Injuries / Conditions section
Use the following at your own risk; I'm not a doctor;
this is not medical advice; no liability accepted.
- Take Red Cross first-aid classes.
Fairly cheap, invaluable, will change your attitude.
- Assemble your own medical kit instead of buying a
Maybe buy the contents outside of
the USA. Cheaper.
But most important: when you get done,
you'll know exactly what is in there and why.
Divers Alert Network (DAN)
sells a kit appropriate for divers.
- There is no one "ideal" list of items you should have
in your medical kit.
Instead, tailor your kit to the type of
trip you're about to make.
This includes thinking about:
- What problems might occur (most likely, and worst).
- How many people are involved, their conditions and skill levels.
- How long the trip is, and how far from help you'll be.
- Best and worst that environment might throw at you.
- Other gear that will be present (for improvising).
- Capacity to carry the kit, and how to protect it.
- Division into multiple kits, for side-trips or because of weight.
- Possible/likely injuries/problems while cruising on a boat (most likely first):
- Chapped/dried skin from windburn or salt.
- Swimmer's ear (water in ear canal causes inflammation and infection).
- Sprains/strains, including back injury from raising anchor, hoisting dinghy, etc.
- Food/water poisoning.
From a health article: "there may be as many as 81 million
illnesses - and more than 9,000 deaths - [in the USA] from
food-borne bugs each year"
and "the vast majority of 24-hour flu in this country
is actually food-borne illness".
- Allergic reactions to insects or food.
- Broken bones.
(I broke a toe when I got tired and accidentally bashed my bare foot
into the companionway.)
- Dinghy-related accidents; the outboard propeller is a menace.
- Heart attack.
- Bag medications into zip-loc bags by treatment group
(cut, burn, sting, etc) and label each bag.
- Get examinations for likely conditions before a long cruise.
Heart check, prostate exam, dental checkup, eye exam, etc.
And check yourself:
16 Ways to Monitor Your Health Between Checkups.
- Get appropriate vaccinations.
- Get supply of drugs from your doctor before long cruise.
Carry the prescriptions with you;
customs officials may require them.
Prescriptions should mention the generic names
as well as any brand names.
Carry eyeglass prescription as well.
Getting prescriptions filled when you're away from your home doctor:
From article by George Sass in May/June 2006 issue of Power Cruising magazine:
- Have new prescription orders mailed/faxed from doctor to you; have them filled locally.
- Get extra, undated prescription orders from doctor before leaving.
- Some/many pharmacies won't fill a prescription more than a year old ?
- Tell insurance company you're going on long trip; they may let
you buy more than a 30 or 60-day supply of medication.
Don't buy too much; it expires.
- Some medications that are prescription in USA are non-prescription in other countries.
You'll find it impossible to get a prescription written in one state filled
in another state; each state has its own laws about prescriptions,
and often has different laws for different drugs. (But try a pharmacy
used by commercial-fishing boats, in a busy seaport; they may fill
a prescription faxed from your doctor.)
- Carry medications and supplies even if you're not sure how to
use them; you can consult a doctor by radio.
- Carry a copy of your latest medical
records (blood pressure, blood test results,
immunizations, dental x-rays, etc).
If you fall ill, the hospital
can compare your new test results to the records you carry.
- Keep a medical log of everything that happens (for legal reasons,
for tracking changes in condition over time,
for recording consumption of controlled drugs).
- Keep controlled drugs under lock and key.
- Have a skin-cancer examination once per year. Very important.
Three types of skin-cancer:
EPA's "The Sun, UV, And You"
- Basal cell: usually raised, pearly; clear or flesh-toned;
may crust or bleed.
- Squamous cell: usually pink, scaly.
- Melanoma: usually asymmetrical, irregular border, non-uniform color,
diameter more than 6 mm (size of pencil eraser),
irregular elevations, may feel burning, bleeding or itching.
SailNet - Joy Smith's "Protecting Ourselves from the Elements"
- Avoid blood transfusions outside the USA: blood
screening typically less reliable. If having elective
surgery, give your own blood ahead of time.
- The Caribbean has the second-highest incidence of HIV and AIDS
in the world, after Africa.

Medical advisory services:
From John Harper at Medical Advisory Systems
1. Medical Advisory Systems, Inc. (MAS, for short) does have a medical
advice hotline, available to our subscribers on a 24/7 basis.
George Washington University
MedAire / MedLink
2. The annual subscription is $400 per year. This entitles you to contact
with our duty physician within a minute of the time you call, again, on
a 24/7 basis. Also included for the $400 fee are: medical record
storage for two persons; a quick communications guide; a radio drill
manual; and advice about stocking your vessel's medical locker.
3. Yes, the hotline can be contacted by radio. Many of our clients use
single sideband radio or a relay through a shore/marine radio station.
From Jeanne Pockel's "Cruising Dictionary":
If you need medical care outside of Western Europe, USA, Australia, NZ,
we strongly urge that you do not go to the local hospital.
In major towns and cities find the private clinic that treats
the well-to-do (applies to every South American country,
every Caribbean island, and most Pacific islands).
If you can find it, read a book called "Sitting Ducks".

- Adhesive tape
From Bev Clary on Cruising World message board:
[Carry] plenty of 'real' adhesive tape,
sometimes known as trainers tape or athletic tape.
Unlike the stuff found in first aid kits, will
stick to wet sweaty people."
Topical anaesthetic: Opthane.
Simple anaesthetic for splinters and such:
chill skin with wrapped ice cube.
- Anaphylaxis kit ?
(Same as antihistamines ?)
For treating anaphylactic shock in someone allergic to insect bites.
Asthma inhaler (bronchodilator).
Epinephrine (EpiPen or Ana-Kit auto-injector).
From Jeanne Pockel on Cruising World message board:
I just heard that a cruising friend just died of anaphylactic shock
in a hospital in Thailand (in less than three hours from first
signs of the allergic reaction). Scary. My point is that a doctor
friend, years ago, insisted that we carry Children's Benadryl at
all times for just those times when we have an allergic reaction
to something new. Children's Benadryl because it's a liquid and can
be swallowed when pills might not be, and acts faster than a pill.
I am so grateful that I took this person's advice - I've had two
severe allergic reactions to things that I encountered on the boat,
and the three hours or so that it would have taken us to get to
medical help would have been too long.
- Antibiotics and Antiseptics
Very important in Tropics;
very easy to get infected, and infections spread quickly.
You may have to use 2x of the normal antibiotic dose (or more).
- Broad-spectrum oral antibiotics: Cipro, Erythromycin, Keflex,
Dicloxacillin, Septra DS, Bactrim DS, Bactrim Fort,
Ampicillin, Amoxacillin, Augmentin, Penicillin V, doxycycline,
Trimethoprim/Sulfa double strength (e.g. TMP/SMX DS, Bactrim DS, Septra DS),
- Injectable antibiotic: cephtriaxone.
- Antibiotic ointment: Betadine, Bacitracin (check expiration date).
- Antibiotic ear-drops: Cortisporin, Amoxacillin.
- Antibiotic eye-drops: sulfacetamide.
Types of anti-microbials,
mostly summarized from "Medicine For Mountaineering" edited by James Wilkerson
There are quite a few kinds of antibiotics, organized by either
chemical class, mechanism of action, or type of bacteria. ...
Bacteria are often classified as gram positive (mostly skin organisms like
staph and strep) or gram negative (mostly intestinal bacteria like E.
coli). They are often also classified as aerobic (requiring oxygen) or
anaerobic (nasty bugs like that causing gangrene).
Some useful antibiotics to have on board would include:
- Ampicillin/amoxicillin - general antibiotic, could be useful for sinusitis,
- Augmentin - good for infections involving gram positives and negatives,
aerobic and anaerobic.
- Keflex - good for skin infections.
- Metronidazole - good for anaerobic bacteria.
That's just a suggested few off the top of my head. You have to keep in mind
that oral antibiotics have limited usefulness in anything other than
superficial infections. If whatever you're treating looks like an infection
and does not improve reasonably quickly, you would need to go somewhere to
have it looked at and consider the need for intravenous antibiotics.
Use antibiotic powders for open oozing wounds, antibiotic
ointments for under-skin infections.
- Povidone-iodine (Betadine, Povidine, Pharmadine, etc).
- Benzalkonium Chloride (Zephiran).
Good for deep wounds; must store in glass bottle.
- In a pinch, 70% rubbing alcohol.
- For treating established infections:
About 10% of patients are allergic.
Kill cocci (strep throat, cellulitis, boils, abscesses, wound infections, pneumonia).
Ampicillin is the only penicillin that is effective
against gastrointestinal problems (diarrhea, dysentery, typhoid).
Good oral penicillins: cloxacillin, dicloxacillin.
Ceclor, a cephalosporin antibiotic, is used in the treatment of ear, nose, throat,
respiratory tract, urinary tract, and skin infections caused by specific bacteria,
including staph, strep, and E. coli.
Some patients allergic to penicillins are also allergic to cephalosporins.
Substitute for penicillins in allergic patients.
Not as effective as penicillins.
Used only for serious infections.
Can damage kidneys, inner ear.
Not as effective.
Useful for diarrhea and cholera.
Become toxic when outdated.
- Neosporin (a mixture of 3 drugs).
- Bactrim, Septra (a mixture of 2 drugs).
Antiseptics: hydrogen peroxide (turns into water after 6 months;
you have to replace it), mercurochrome, alcohol.
(Overlap with Anaphylaxis kit ?)
Used to reduce swelling (including swelling that threatens airway).
Hismanal, Benadryl, adrenaline.
- Automated External Defibrillator (AED) ?
$1500 ? Requires prescription ?
These are very easy to use: just put two pads
in the right places and push a button.
The machine decides if a shock is appropriate,
tells you to stand clear, and you push a button to shock.
From someone at Red Cross, in late 1999:
Senate Bill 911 was passed [in 1999] to protect
laypersons who use an AED under the 'Good Samaritan Law'.
American Red Cross training is named in that Senate Bill.
You do need a Doctor's prescription to purchase
an AED, and that is usually no problem.
You can purchase AEDs directly from [Red Cross].
There are several bad states a heart may be in: tachycardia, fibrillation, arrest.
An AED only works against fibrillation, but most heart-attack victims
are in fibrillation for a minute or two before progressing to full arrest.
So quick use of an AED is critical.
Performing CPR extends the fibrillation period a bit.
- Blood pressure measurement:
- E.g. "Tens" from PCP ($100).
Take it to a clinic or hospital to "calibrate" it.
- Body Substance Isolation (BSI):
- Gloves: get latex gloves at most big drugstores.
- Rescue breathing mask,
Ambu Res-Cue Mask,
but you can buy Laerdal w/o O2 port at Red Cross for exactly $12
(no tax or shipping if you pick it up yourself).
- Calamine lotion or hydrocortisone
cream (islands have "poison wood").
- Charcoal tablets
From Jeanne Pockel's "Cruising Dictionary":
Available in most health food stores.
Good for absorbing ingested toxins such as Salmonella toxin from food poisoning,
or for accidental overdoses of medications.
It is not a medicine, but the same activated charcoal used to absorb minerals
and odors from drinking water. Must be taken when symptoms first appear to
have any effect. Can’t hurt, often helps, and with food poisoning, helps dramatically.
Tincture of iodine, diluted bleach.
- Ear medicine:
Otic Domeboro, Cortisporin Otic solution.
- Gauze roll
Use "vet wrap" (from feed or pet store) instead;
works better in wet conditions.
- Hypodermic needles:
To make sure a doctor doesn't use
a re-used needle on you, provide your own needles.
- Otoscope: magnifying lense with light.
Good for looking into ears, removing small spines and splinters, etc.
Maybe through Divers Alert Network ?
Note: medical oxygen is not the same as welding oxygen.
Medical oxygen is moistened so it doesn't dry out the airway.
Note: SCUBA uses compressed air, not compressed oxygen.
Breathing pure oxygen at depth is deadly.
- Snakebite kit.
- Surgical stapler, and staple remover.
- Toothache kit.
From Coastal Cruise - The FAQ:
"Wax for braces - helpful if your tooth pops
a filling and you can't get to a dentist."
- Water-purifying tablets.
Globaline or Potable Aqua (tetraglycine hydroperiodide).
Twenty-Four Methods To Purify Water
Water Treatment Methods
From "Medicine For The Outdoors" by Paul Auerbach:
Use boiling or iodine-based methods or intensive filtering to purify water;
chlorine-based methods are less effective, have shorter shelf-life, lose potency when exposed to air.
- Witch hazel:
Good for sun-glazed eyes, itchy bug bites,
sunburn, general soothing/cooling of skin.
- Wound plaster ?
From kaj on Cruising World message board:
... Compeed Hydro Cure System plaster. It cures cuts and grazes and prevents the minor
infections to develope. Another item first used this summer was cooling foam
in a spray bottle to ease the pain of a badly burnt hand. Then
on with Compeed plaster. Although the rope burn took off pretty much of skin,
there was no pain or aching, plaster on and forget. Then 4-5
days later, when I went to the doctor, everything was healed.
Overseas prescription drug suppliers:
Imported Drugs.Com (generic drugs; high shipping cost)
Pharmacy International Inc (moderate shipping cost)
From John / truelove on World-Cruising mailing list:
My doctors say that most prescription drugs are good for 2 years, despite expiration dates.
Do *not* photocopy your prescriptions - it's illegal to do so.
Ask your doctor to give you 2 originals - get one filled and
take the other with you. Prescriptions should be understood by
From John Titterton on World-Cruising mailing list:
Some prescription drugs are like colour (color in the US) photographic
film - it loses sensitivity and stability before the expiration
date when in humid and/or hot conditions. I
keep film and prescription drugs that are not stable or deteriorate
quickly in the refrigerator. They do not take up much space, and it will
normally extend their useful life well beyond the expiration date.
There are exceptions to this, such as compounds or medications
made from animal extract or ones with a high natural content
in cream form. My wife also uses some special drops for her
eyes to treat enzyme infections once in a blue moon - she
wears contact lenses. This small bottle has a very short
shelf life (6 months from manufacture) and once opened
should be thrown away after two days, before the infection
has cleared up. We experimented keeping the unopened
bottle (you can fit two into a matchbox) in the refrigerator
and found that it was still 100% effective after a year.
Also, once opened and kept in the refrigerator, it lasted
approximately a week instead of the two days.
From John / truelove on World-Cruising mailing list:
A pharmacist once told me to not only keep the
cream he had made up for me in the refrigerator, but
to keep a small plastic film on the surface of the cream
to prevent air reaching it. He informed me the cream
would deteriorate quickly if exposed to the air and
become ineffective. It cured my ailment quickly and
thus I was never able to see how long it would actually last.
You make some good points. I had not thought of compounds -- of course
you are right. I recall when the Trans-Derm Scop patch was temporarily
banned and I was able to get topical syringes filled with
Scop gel -- it had to be constantly refrigerated.
When I quoted my doctors, I was referring to caps like Vioxx
and Cephalexin and also BP meds, which I should have clarified.
It's true that cooler and less humidity is better.
You can buy frames and lenses very
cheaply through the internet (although
customer service can be bad if anything goes wrong).
The process is explained at
Glassy Eyes' "Online Eyeglasses: How it works"
Use store links
on Glassy Eyes
to get extra discounts.
But you still need to visit an optometrist to get an eye examination and prescription (make
sure it includes your Pupillary Distance and Near Pupillary Distance).
This costs $50-$100 (try Walmart or CostCo for cheapest ?), and really should be done every year or two.
And you need the frame measurements, best taken from an existing set of your frames.
The measurements will be in the form
"Lens Width - Bridge Width - Temple Width (earpiece length) - Lens Height", in MM.
Often the first three numbers are stamped on the earpiece.
My experience 7/2009:
I had an eye-exam done and a prescription written ($35), then ordered progressive bifocals
Price ($85 including shipping) and speed were great. I ordered grey frames and received brown frames with
"gray" stamped on the inside of the earpiece !
I'm not happy with the progressive bifocal lenses:
the lens size is too small and the near-distance field of vision (in focus) is much too narrow, but
that seems to be a common complaint about progressive bifocal lenses, and nothing
to do with ordering through the internet. Someone suggested that more expensive
lenses may have wider fields of vision (in focus).
At exam time, the optometrist looked at my
old with-line bifocals and said "you won't be able to get big lenses like that any more",
so maybe I couldn't have done any better on the "too small" issue either, buying off-line.
"I know a man who gave up smoking, drinking, sex, and rich food. He was healthy right up to the day he killed himself."

Injuries / Conditions
From Beth Leonard's "An Apple a Day When the Doctor's Away":
- Anxiety attacks; it is not uncommon
for someone to panic when far offshore.
- Silvadene ointment (silver-sulfadiazine).
- Foille burn ointment (topical antibacterial containing neomycin,
polymyxin B, and bacitracin).
- Vitamin A and D ointment.
- Fresh aloe-vera gel from fresh leaves.
- Water-Jel and Burn-Jel
- Immediately soak in cold or iced water for 15 minutes.
- Leave wound open, or coat with plastic skin or very soapy
water or paste of baking soda and water.
- Don't break blisters.
- Toothpaste is good on minor burns, especially steam burns.
- Apply soy sauce, or miso paste.
To avoid scarring while a serious burn heals, keep it very moist; don't let
the skin dry out and a scab form.
- Clean with soap and water.
- No oils or ointments.
- Leave wound open.
- Keep victim warm.
- Give plenty of fluids, with salts.
- Cuts / sores / scrapes:
- Clean with warm soapy water, or antiseptic solution, or hydrogen peroxide.
- Antibiotic cream or powder.
- Bactericidal soap: Hibiclens.
- Keep salt water out.
- On clean, recent cuts, use spray-on bandage (Mistdress).
- If deep and not bleeding, or animal bite, or dirt in it, start antibiotics.
- From a Lonely Planet guide:
"(in hot climates) ... Where possible avoid bandages and Bandaids, which can keep wounds wet.
Coral cuts are notoriously slow to heal, as the coral injects a weak venom into the wound. ...
clean any cut thoroughly with hydrogen peroxide if available."
- Symptom may be a headache.
- To reseat a crown temporarily, use Vaseline instead of cement,
to avoid sealing in decay.
- To reseat a crown, use temporary denture glue (available over-the-counter).
- For a broken tooth or loose filling, use two-part zinc oxide dental cement (available over-the-counter).
- For an infected or abscessed tooth, use antibiotics.
- Digestive / Diarrhea:
From Judy Lamar's "Illnesses Related To Water":
- Antacid (Tums).
- Milk of Magnesia.
"Prevent or control dehydration. ... For most causes of diarrhea, no medicines are needed, and can cause
harm because they work like a plug keeping in what should be coming out."
- Drowning victim:
BoatSafe's "Help Prevent Drowning with These Tips"
If in cold water (especially if a child), they may be alive.
Perform CPR. They are not dead until they are warm and dead.
- Ear infection:
- Prevent with 50/50 isopropyl alcohol / vinegar drops after swimming.
- Treat with drops containing cortisones and antibiotics.
- Treat external infection with merthiolate solution.
- Fever blisters (especially on lips, from sun):
- Itchy Fiberglass fibers on skin:
- Vacuum off fibers, then apply and remove adhesive tape.
- Don't take a hot shower; it opens the pores and lets fibers in.
Wash with very cold water and soap/detergent.
- Benadryl or Calamine lotion for itching ?
- Fiberglass splinters in skin:
- Apply and remove adhesive tape, again and again.
- Fatigue / Exhaustion / Sleepiness when on passage:
- Do any extra sleeping (with lack of a proper watch) when well at sea,
not near land or shipping lanes or fishing areas.
- If not on watch, you should be sleeping.
- Fungus infection of skin (jungle rot, tinea versicolor, sun-spots):
selsun lotion, Selsun-Blue shampoo, tinver lotion.
If using Selsun-Blue shampoo: wet the skin, apply
shampoo to spots, let dry for 5-10 minutes, wash off. Do
every day for at least 3 weeks.
- Athlete's foot: Tinactin, Lotrimin, sunshine.
- Hyperthermia (too hot):
- Hypothermia (too cold):
If serious hypothermia, warm trunk of body before warming extremities.
Very easy to get infected in Tropics, and infections spread quickly.
Signs of infection: swelling, redness, heat, discoloration, pus ?
Basic prevention/care for infections:
Types of infections, mostly summarized from "Medicine For Mountaineering" edited by James Wilkerson
- Clean the wound.
- Protect with clean dressing.
- Change dressings frequently.
- Let the wound drain naturally.
- Soak crusted wound in warm disinfected water with antiseptic.
- Take antibiotics.
Summarized from "Yachtsman's Emergency Handbook" by Neil Hollander and Harald Mertes
- Abscess / Boil:
If larger than 1 inch, or fever or chills, use cloxacillin.
- Cellulitis (skin red, swollen, hot, tender, not sharply demarcated, usually fever):
Use cloxacillin, and hot wet compresses to increase circulation.
- Bacteremia / Septicimia (chills, high fever, sweating, prostration):
Use nafcillin and gentamicin, and rest, warmth, soft diet,
fluids, mild pain medication, acetaminophen for fever.
- Typhoid / Dysentery:
Use sulfa or chloramphenicol (Bactrim, Septra).
- Influenza (chills, fever, muscle aches, coughing, weakness, headache):
No antibiotics. Rest, warmth, light diet, mild pain medication.
- Malaria (muscle soreness, low fever.
Later, chills and fever.
Then repeated febrile episodes: feeling of intense heat,
headache, delirium, high temperature.)
- Cryptosporidiosis (severe diarrhea):
There is no adequate treatment.
Women's vaginal yeast infection: use Monistat.
- Chest, throat, ear infections, boils, infected cuts: use tetracycline.
If no improvement after 3-4 days, switch to ampicillin or erythromycin.
- Urinary tract infection: use Bactrim or Septrim.
- Dysentery: use tetracycline.
If no improvement after 3-4 days, switch to Flagyl.
- Skin infection, minor infected wounds: use Bacitracin (check expiration date) or Neosporin ointments.
- Eye infection: use chloramphenicol drops.
Fungal infection: use Clotrimazole.
Skin infections: use antibiotic powders instead of ointments.
- Insect bites:
Apply baking soda or witch hazel or soap to reduce itching.
- Lightning strike victim:
Heart/electrical system may be severely disrupted but recoverable.
Perform CPR, for hours if possible; victim may revive long after the event.
- Poisoning (lots of nasty chemicals are on board):
Good practice to have the MSDS (Manufacturer's Safety Data Sheet) for every product
that you use on board.
Fume poisoning: common symptoms are drowsiness and headache.
Carbon monoxide poisoning is very insidious: victim may appear to recover within hours,
then crash and die a day or two later. Supply oxygen and get them to a hospital even
if they appear to have recovered.

Seasickness article in 7/2000 issue of Cruising World magazine
SailNet - Liza Copeland's "The Delicate Art of Preventing Seasickness"
SailNet - William Mahaffy's "Dealing with Seasickness"
From Roger and Misty Jones on the
WorldCruising mailing list
... sea sickness comes with the territory. Some will succumb, some
will not. However, don't read that the same will succumb each time. It
doesn't work that way. One time it will be their turn, the next time
- Acclimate people to the boat slowly; don't go from land
to close-hauled ocean sailing in one jump.
Spend some time just sitting on the boat,
then some gentle sailing.
Sleep overnight on boat before starting trip ?
- Eat something light.
- Drink adequate amounts of water.
- Start taking medicine a day ahead of time, to get it
in your system and to find out any side-effects.
- Minimize time belowdecks, especially in enclosed spaces.
- Avoid diesel and exhaust fumes.
- Volunteer for helm duty.
- Ask helmsman to sail boat on gentler point of sail.
From Dave Richardson on the
WorldCruising mailing list
... My experience would indicate that most people "overindulge"
the night before leaving port. Myself included. Then add foods
which don't do much for our stability and we have created a
monster waiting to explode over the side.
Lee I hope. Start by trying to treat this cause but good luck. ...
From Roger and Misty Jones on the
WorldCruising mailing list
... Most sea sickness medicine is useless if taken after the problem; you
need to take it before you set out. ...
From Matt Pedersen on the Morgan mailing list
My Scottish grandfather always told me the best way for a Scotsman not to
get seasick was to put a penny in his mouth. It takes a lot for a Scotsman
to part with his money.
From Matt Pedersen on the Morgan mailing list
From our last Safety at Sea seminar, here's a list of medications and their
|Scopolamine Gel Xtr||Scopolamine|
The Cinnarizine is not available in the USA, but it is in some other
Dimenhydrinate and Meclizine are usually effective for most people (I do
pretty well with Meclizine).
Promethazine and Scopolamine are available by prescription only. The
Promethazine also comes in a suppository form for really drastic cases.
BTW, Scopolamine was off the market for a couple years not because it was
ineffective but because in its original form there was no control over the
dosage - an 80 pound person got the same amount of medication as a 240
pounder. The latest generation of Scop medications takes care of that.
The doctor who gave our SAS talk said it may be necessary to take some sort
of stimulant (e.g. NoDoze) to avoid drowsiness. He also recommended that
you take these medications while you're going about your daily business
sometime to see if there are any side effects. It's not a good idea to
learn about those things while you're at sea. ...
Early signs of seasickness: sleepiness and lethargy.
From Roger and Misty Jones on the
WorldCruising mailing list
... Get the sick person on deck. Seeing the horizon and getting fresh air
tend to help. If they can doze off on deck so much the better. But remember,
they are sick. Make sure they are harnessed and latched to the boat so they
don't go overboard when doing the old heave ho!!!! Part of sea sickness is
loss of balance. Remember that and don't let them near the storm rail
without a safety harness. ...
From SailNet - Sue and Larry's "How to passage safely and comfortably":
We have found that the active ingredient in Bonine and Dramamine II,
meclizine hydrochloride 25 mg, works great without causing drowsiness.
If you want to fall asleep fast, take the regular Dramamine.
They should market this product as a sleep pill.
[Meclazine is cheaper than Dramamine II / Dramamine Plus.]
Compazine suppository (prochlorperazine).
Includes a little anti-anxiety medicine too.
"Navy Cocktail": 50 mg ephedrine and 25 mg Phenergan (promethazine).
Scopolamine patch can cause blurred vision.
And don't touch the patch and then rub your eyes.
Electronic wrist-band: ReliefBand ($100)
A smart-phone application that you listen to through headphones: Nevasic
Other remedies recommended by various people:
ginger (dried candied, or ginger snaps),
wrist-pressure-strap (can be used after symptoms appear;
velcro better than elastic, must be tight),
eye-patch over one eye (maybe that's why pirates are
always pictured with an eye-patch !),
Marezine (spelling ?).
Vomit into a bucket, not directly over the side (unsafe).
A severely seasick person needs to be supervised closely:
watch for dehydration, overexposure to heat/cold,
make them wear a harness abovedecks (balance is affected,
and survival instinct is suppressed).
Sail boat more gently (less close to wind) to reduce motion.
From John Smith in 5/2006 issue of Caribbean Compass magazine:
Recognize a stroke by asking the victim to:
- Talk coherently.
- Raise both arms.
If they can't do any one of these, get help immediately.
Also, if when they stick out their tongue, it is crooked (goes to one side or the other), that
is an indication of a stroke.
Cool wet compresses.
Vitamin E oil.
Pure aloe vera gel.
Sunscreen that has been refrigerated.
Baking soda paste to relieve pain.
Talcum powder on the bedsheets.
Dab wet teabags on and let liquid evaporate.
Watch out for dehydration.
Maintain proper body temperature.
PABA pills ?
Zinc oxide cream.
Facial cream/moisturizer with sun protection (less oily than
suntan lotion), such as Oil of Olay.

years-old sunscreen may not work.

- Venom / stings:
- Jellyfish stings:
- Seawater (not fresh water) to wash
off tentacles without activating them.
- Use gloves or rags to pull off tentacles.
- Wash with vinegar.
- Wash with fresh water and dilute ammonia.
- Coat area with baking soda paste.
- Take antihistamine (Benadryl) ?
- Stingray stings:
Summarized from letter from Jan Loomis in
6/2001 issue of Seven Seas Cruising Association bulletin:
- Avoid stings by shuffling your feet (not lifting up and down)
as you walk on the bottom.
- Wash wound with fresh water.
- Remove foreign material from wound.
- Immerse area in hot water for 30-90 minutes;
continue to remove foreign material.
- Take pain medication.
- Apply sterile dressing, elevate the wound,
stay out of seawater, let wound drain.
- Infection is very likely; start antibiotics.
- Sea-urchin spines: don't try to remove them; treat with hot lime
juice to help dissolve them, or use urine to neutralize the toxin.
- In general, treat sea-life stings/venom with wet compresses as hot
as you can stand them; it breaks down the venom.
- You can buy an electrical device that will heat the skin just in the area
of the sting, using electricity, and breaking down the venom.
- Benadryl to reduce swelling.
- Windburn protection:
Thin coat of petroleum jelly (on top of sunscreen).
Allergy and infection can give same symptoms: heat and swelling.
Rub area with cortisone cream.
If it works, you have an allergy: take an antihistamine.
If it doesn't work, you have an infection: take an antibiotic.
Always follow instructions from doctors: pic

International Association for Medical Assistance to Travellers (IAMAT)
Some of this from CDC and Travel Health Online:
- Amoebic Dysentery:
Parasitic; don't treat with antibiotics.
See doctor; treat with oral medications.
Parasitic: don't swim in fresh water in South America, Caribbean, Africa, Asia.
Very similar to Dengue fever: spread by same mosquitoes, no vaccine.
In most of Central and South America, including Mexico and Venezuela.
A single vaccination is effective for 2 to 6 months.
The vaccination is only about 50%-80% effective.
Treat with fluids and antibiotics.
See doctor; some complications can be fatal.
- Dengue fever:
Rare, but present on all Caribbean islands (mosquito-borne).
Symptoms: fever, headache, muscle and joint pains, skin rash.
There is no vaccine.
There is no specific treatment;
replenish fluids and take non-aspirin pain reliever;
taking aspirin while infected can lead to internal bleeding.
Viral; don't treat with antibiotics.
See doctor; there are two types and four viral varieties of the fever,
and some complications can be fatal. In particular, if you get strain X first,
and later get a different strain Y, the second time you can get Dengue Hemorrhagic Fever and die.
From Ken on Facebook:
"Generally speaking, mosquitos aren't usually much of a problem on the boat in most anchorages.
Marinas, boatyards and shoreside restaurants and bars are where those pesky Aegypti mosquitoes are.
They will silently get you under the table while you're playing dominoes in the afternoon or
having sundowners and dinner ashore. Strong insect-repellent sprays such as DEET may help to minimize your risk of being bitten."
Treat with Fasigyn (tinidazole) or Flagyl (Metronidazole).
- Hepatitis A:
Transmitted by ingestion of contaminated food or water, or through direct contact with an infectious person.
Symptoms: long-term fatigue, fever, nausea, stomachache, appetite loss, jaundice, dark urine, diarrhea.
"Vaccination should be considered if travel
to areas of questionable sanitation is anticipated." (Central and South
America, Mexico, Caribbean. Especially Mexico, Jamaica, Haiti.)
"Immune Globulin" is one vaccine; it provides temporary immunity;
clinic recommends better 2-shot vaccine.
Vaccination is 2 shots about 6 months apart; first shot gives good
protection; second probably gives lifetime protection. Get first shot
at least one month before travel.
The vaccine is 94-100% effective.
- Hepatitis B:
"Vaccination is advised for ... persons planning extended
stays of 6 months or greater (especially those who anticipate using local health care
facilities, staying in rural areas, or having intimate contact with the local population)".
Don't need it unless you're in risk of contact with blood or other body fluids of
Vaccination is 3 shots over 6-8 months.
Common in the Caribbean and USA.
Present in the tropics and subtropics.
In the Caribbean, mainly in Haiti and the Dominican Republic.
You don't get a vaccination for malaria;
you take prescription medicine before/during/after trip (usually start one week
before and end several weeks after).
Not all anti-malarials work in all areas;
you have to get the right one for your area.
But strains change and migrate, so the appropriate
medicine may vary from year to year.
Anti-malarials often are ineffective.
Summarized from a Chicago Tribune article by Alfred Borcover:
In USA, there are 3 drugs commonly used:
- Chloroquine (Aralen): taken orally once a week.
Ineffective in severe malaria areas, but
often used for Central America, Haiti, parts of Mediterranean.
- Doxycycline: taken orally every day.
Effective in severe malaria areas.
- Mefloquine (Lariam): taken orally once a week.
Effective in severe malaria areas.
Can have fairly severe side-effects (hallucinations, nightmares).
The disease is much worse than most of the possible side-effects.
Malarone pills: one per day, $8 per pill. Start 2 days before trip,
continue 7 days after trip.
Symptoms (can appear months after exposure): fever, then chills and aches, then organ failure.
Use physical prevention (screens, nets, DEET, long-sleeved clothing).
Some cruisers, and reportedly some doctors in Guatemala, disagree
with the "disease worse than side-effects of the medicine" statement.
They say the strain in the NW Caribbean is easily cured,
and the possible side-effects of the preventive pills include death.

ICT Malaria Pf test, both awaiting FDA approval ?
"The most frequently used anti-malarial drug
is hydroxychloroquine and the most
common trade name for this is 'Plaquenil'."
Generic (Hydroxychloroquine Sulfate) at drugstore.com
Another medicine: Chloroquine (chloroquine phosphate tablets
or chloroquine hydrochloride injection).
In Caribbean (in Haiti and Dominican Republic and Central America),
take either Proguanil daily or Chloroquine weekly.
"The anti-malarial medication [for Central African Republic]
is mefloquine (Lariam)." [Also for Brazil.]

- Poliomyelitis (Polio):
Vaccination good for 5 years.
A parasitic infection; found in fresh water in parts of Antigua,
the Dominican Republic, Guadeloupe, Martinique,
Montserrat, Puerto Rico, and St. Lucia.
Do not swim in fresh water (except in well-chlorinated swimming pools)
in these countries."
Vaccination good for 5 to 10 years.
Present in Latin America. You can get it from swimming in polluted water
(most islands don't do sewage treatment ?), or by eating
risky foods (contaminated food or water, and raw vegetables or fruits that
can't be peeled).
Symptoms: sustained high fever, often fatigue, headache, loss of appetite. Must have test to confirm.
The vaccination is only about 50%-80% effective,
but also significantly reduces severity of infections that do occur.
Two forms of vaccination: one shot (inactivated virus) taken at least 1 week before travel,
or four-pill regimen (attenuated virus).
Boosters required every 5
years for the oral vaccine and every 2 years for the injectable vaccine.
More frequent booster recommended in known risk areas.
Treated with antibiotics.
- Yellow fever:
Present in some parts of Brazil,
Trinidad and Tobago. Spread by mosquitoes.
Get a "vaccination certificate"; other
countries may require it when you enter.
A single vaccination is effective for 10 years. Get it at least 10
days before traveling.
CDC yellow fever info.
Immunizations, summarized from "Medicine For Mountaineering" edited by James Wilkerson
- Viral vaccines (hepatitis A, tetanus, diptheria, and others):
can be given 6 months or more before trip; benefits persist for years.
- Bacterial immunizations (typhoid, cholera, and others):
must be given just before trip; benefits don't persist long.
From Donal Philby on the SailNet liveaboard-list:
I just received $500 worth of vaccinations and other health medications prior
to an upcoming trip this month to Thailand, Cambodia and Laos. Holy smokes!
And another $300 for hep A and B boosters on return.
From Franz Karl Byars on the SailNet liveaboard-list:
Included in this is Malarone, an anti-malarial which you take a couple days
before and all during and for a week after returning. At $5.75 a pill/day
(some pharmacies sell this for up to $13/pill), this is no small investment.
It was $170 for a three-week trip. But after watching my father suffer
recurring bouts of malaria contracted during WWII in the Pacific, I'm not
interested in sharing that experience.
It made me realize that planning a cruise through malaria-prone areas of the
tropics could prove wildly expensive unless one can find a cheaper source of
such medications. The source I found seemed less than other places. I'm
going to check to see if these could be gotten via VA hospital (I just got
my records to apply for services, if needed).
I expect that the health precautions are going to cost more than our on the
ground travels, since we are going where things are cheap.
As one who prescribes Malarone for travelers, I'm pretty sure that you
don't take the med on a daily basis but once a week. You should start
the med prior to leaving and then continue the med for at least 3 weeks
after you leave the infested area. You should double-check on the
From Rick Kennerly:
Re: Getting vaccinations:
Not a lot of doctors carry these vaccines because they expire before they
use them all, so they will order them or send you where you can get them.
Most hospitals do have a vaccinations nurse. Some county health departments
do some or all vaccinations for free. But any county health department will
know where to get the shots in your local area.
Prices of vaccinations (11/2004 at Marathon FL health clinic):
Cholera: 1 shot $36.
Hepatitis A: 2 shots $68 each, at least 6 months apart.
Hepatitis B: 3 shots $60 each, over a 6- to 8-month period.
Typhoid: 1 shot $70, or four-pill regimen ($???).
Tetanus booster: 1 shot about $36.
Yellow Fever: 1 shot $90.
I decided to get hepatitis A and typhoid vaccinations before my
Caribbean cruise, on the theory
that you can get those diseases from contaminated water.
I think my tetanus is up-to-date.
[Later, got a Tetanus booster in Salinas PR for $10.]
From article by Bernadette Bernon in 11/2003 issue of Cruising World magazine:
We met one crusty coot who'd had such a wicked toothache on a
transocean passage that he finally wrenched it out with vise-grip pliers,
"leaving only one damn tooth on top," he crowed, "What the hell good's
that ? I pulled it out, too."
"Lucky he didn't have a urinary-tract infection," Douglas whispered to me.

"You can't catch scurvy," Julie said. "You get it from not eating enough oranges."
"That's an old wives' tale," Monk said. "From wives who later died of scurvy."
