This discussion is making me very curious about Larium, its effects and "side" effects. Could someone explain? What symptoms does it cause that could be confused with culture shock, "travel stress," etc.?

I would like to query Judith Krieger what she includes among her old fashioned remedies for malaria. I am currently working with two students who will be overseas next year: one in Mali, the other in Tanzania. If there are ones she would recommend as "supplements" or in lieu of the others, please advise. . .at least for discussion with medical advisors.

This drug has been known to cause serious side effects for several years. I recall being advised about the side effects many years ago when I was about to undertake a six nation tour in countries that are malaria-infested. The extent to which information about the drug and its effect are widely distributed is uncertain. You have provided an excellent service by posting this on the net.

I think western paranoia of African illnesses and their general belief that African medicine/doctors etc. are inferior is a major part of what makes it so hard for them to physically deal with being on the continent.

The problem of doxycyline as a substitute for mefloquine is that for women yeast infections often result. Further, doxycycline must be taken daily and has a limited span of protection. If one misses two pills (or perhaps just one) a possible "window of opportunity" for infection is created.

It would be interesting to know the experiences of PCVs and of state department personnel (especially in plasmodium falciprum areas such as coastal Tanzania and Kenya) with mefloquine.

Also, is length of use of mefloquine a factor for those experiencing significant side effects? I have taken 120 students on three foreign study programs to east Africa over the last four years. All were on Larium as the malaria prophylactic. The exposure period was four weeks. No students experienced what would be considered significant side effects. On each trip two or three women complained of "bad dreams" after taking the tablet at times other than with meals. When taken with food, as is suggested, such dreams ceased or became "less bothersome".

I am interested in the experiences of others with study abroad programs in east Africa.

H-AFRICA's Editor's Note: As issues about anti-malarial drugs began to be discussed on H-Africa, I sent copies to the editor of a new H-Net list on the history of science, medicine, and technology, Harry Marks. Responding to my concern that much of what was appearing on H-Africa was anecdotal information, Professor Marks kindly provided the following. Please take note of his caveats, some of which have already been a part of our discussion here. mep

I promised to send some citations from the medical literature re: mefloquin. These should be available from any good medical library. If you post them, will you please also post the following caveats:

1) I am not a physician, nor have I even read the articles, though I looked at the abstracts and these seemed informative overviews;

2) medical studies (and authors) disagree about the strengths and implications of medical advice, and reading journal articles is a poor substitute for getting that advice directly;

3) the idea of a SAFE drug, to which your discussions allude, is an oxymoron. NO drug is safe--think of the nasty things aspirin can do to your gut or your clotting ability. Whether mefloquin is nastier than the alternatives (or than malaria) is a complex question.

FYI the last item on the list comes from Hoffman LaRoche, the drug manufacturer.

This discussion of Lariam is very interesting, and I thought that I'd put in my two cents worth. After four seasons of archaeology in northern Cameroon, I've come to the following conclusions:

(1) Lariam is a lot more toxic than its makers and most North American doctors will admit.

(2) Larium has very different effects on different people. About half my crew (including me) take alternative prophylactics because of bad reactions to Larium; the other half wonder what all of the fuss is about.

(3) Larium is more effective against chloroquine-resistant malaria than other prophylactics are, but you can still get malaria while taking it (we've had two cases, of about 10 people who have used it).

Personally, this whole thing reminds me of my second season of archaeology in Africa, in 1983. I was told about this new wonder-prophylactic called Fansidar, and took it regularly for 3.5 months. Doctors aren't too happy to hear that now.

Persons of wealth with access to anti-malarial drugs do not die of malaria. Therefore it has always been my philosophy (20 years living in Madagascar) to take chloroquin or nothing as a prophylactic and to have two or three curative doses of various drugs at my disposal, including Larium, should I contract malaria.

I wait until I arrive in Antananarivo to walk into the local pharmacy and purchase chloroquin over the counter for cents a pill, rather than deal with the hassles of seeing a physician and receiving a prescription for the same drug in North America.

The doctor's advisory books in North America tell you that Madagascar is notoriously chloroquin resistant, but most Malagasy (who do not take prophylactic) still effectively cure their malaria with cheap doses of the drug. The cost differential between the two systems is astounding.

Fortunately I have never succumbed to malaria, but I have numerous friends in Madagascar and other malaria endemic regions who do well by this philosophy. Getting sick with malaria is not pleasant, but hitting it early on with curative drugs often has one back to work within a week.

I think Larium as prophylactic is symptomatic of our overly aggressive biomedical ethic and practice and, ultimately, our worst fears about tropical disease.

I took mefloquine/Larium for 5 months in Tanzania during 1992-3, and subsequently used the chloroquine/paludrine combination for another 3 months. I did not get malaria. I was extremely careful to avoid getting bitten. This is ultimately the best defense against malaria, as no drug is 100% effective as a prophylactic. Nor did I experience any of the serious side effects sometimes associated with mefloquine.

However, I did have problems in another respect. One of the side effects is insomnia. For 5 months I did not get enough sleep. After switching drugs I slept better. But in the meantime I experienced many small illnesses of various types which interfered to some degree with my research programme. I am convinced that 5 months of insufficient sleep reduced my immune defences to the point that I could not ward off other illnesses. I think this should be an important consideration for some people. I would have to think carefully about using mefloquine again.

Does anyone know the state of the Colombian developed vaccine tested in Tanzania and Columbia in 1993/4?

As long as anecdotal evidence seems to be the only type available for this thread, due to a distinct lack of public health types on this list, I will add my two cents worth.

My wife and I did a 28 month stint as Peace Corps Volunteers in Mali from 1989-91, we have returned to Mali for research, the most recent trip being an 11 month stay during 95-96 academic year. Early in our Peace Corps service we were switched, (voluntarily) from a malaria prophylaxis regime of chloroquine and Paludrine to mefloquine tablets (Larium).

This was done after I had contracted a not too serious case of malaria. (Serious enough though to convince me that I was not interested in getting it ever again.) We were on mefloquine for at least 18 months with no serious side effects and no reoccurrence of malaria (I experienced occasional dizziness when lying down and the usual vivid dream). My wife did not get malaria at all and also never had serious side effects from the prophylaxis.

On our return to Mali last year we both took mefloquine again and gave a reduced dose to our 3 year old son. (Under the advice of physicians.) Again we were all malaria and side effect free. I have personal knowledge of friends who did not take prophylaxis or only took chloroquine and suffered repeated bouts of malaria, one friend contracted cerebral malaria and survived only because we were able to get her to Bamako, and into the care of Peace Corps medical staff in a timely manner. They estimated that if she had gone untreated for three more hours that she probably would have died.

There are three important points that anyone considering travel, research, or work in chloroquine resistant malaria areas should take from the experiences expressed in this thread. First, the impact of repeated exposure to malaria is a serious long term health threat as well as the very real possibility that malaria can kill you in the short run. (This is particularly true with young children and those who have never been exposed to the parasite). Because of this, whatever prophylaxis is taken, should be taken religiously.

Second, mefloquine is neither 100% effective, nor side effect free, but it can and does provide excellent protection for many people. One should be certain then to take the drug with enough lead time to discontinue its use if the side effects prove to be overwhelming.

Third, there are numerous other things that you can and should do to dramatically reduce your exposure to the parasite. Often over looked, or simply flaunted by Africa veterans as the paranoid activities of a Tenderfoot, are the simple precautions of wearing long pants, socks, insect repellent, use of mosquito nets, screens etc. to minimize the number of bites to which you are exposed.

My final question is this: What sort of responsibility do we have for the physical health of our students who are taking advantage of travel, study abroad and research opportunities in Africa? I was well prepared by Peace Corps who provided extensive training on keeping oneself healthy in the tropics. Others without such training could well benefit from an advisor who provides a realistic preview of these issues and ensures that the student has access to up to date resources about health issues well before leaving home.

I was a Peace Corps volunteer in Kenya in 1991 - 1992. At this time, so I was told, meflaquine (which I believe is the chemical name for the now commercially available drug) was not approved by the FDA. As volunteers - and for insurance reasons - we were required to take some anti-malarial. We were told all the dangers of malaria - and I have now discovered that the facts we were given were exaggerated - and told that there was discovered a chloroquine resistant strain. We were given a choice whether we wanted to take chloroquine or meflaquine.

I chose the meflaquine and was told I had to sign a waiver, releasing the US government of responsibility, if anything went wrong. Young, fearless and ready to try anything, I became part of an FDA study to determine the side effects of meflaquine.

Within two weeks, the crazy dreams started, mostly sexual in nature. Others in my group - women included - recounted the various 'meflaquine dreams' that we had. We were in the Peace Corps; it was the closest we came to the real thing! About a month later is when the negative side effects began.

I noticed that I was considerably less patient - a bad quality for someone attempting to bridge cultures. I became very depressed at the slightest bit of unwanted information. I started sleeping irregularly, which I had never experienced before in my life. (Friends and family will debate this next point...) My hair started falling out at an increasing rate. When I walked through a doorway, I would see the door frame for minutes after, like vapor trails, which although welcomed at some time, became an irritant, thus beginning the cycle of impatience and depression.

I remained on the drug for about 6 months - through my first bout of malaria and then stopped taking the medicine altogether. I ended up contracting another bout almost two years later while working in Somalia, at which point I was not taking anything.

The Peace Corps did periodically ask me about the 'side-effects.' All of these effects were experienced by others, plus bed-wetting.

I will make a recommendation to those who will be in a malaria region for extended periods of time - take nothing, wear insect repellent (Skin-so-soft works wonders), wear long sleeves in the evenings and sleep under your mosquito net. After you have your first bout with malaria, it gets easier. Just make sure you are not alone when you get it. If you feel sick, get help immediately. If you are living 'there,' make friends quickly. The parasite is growing stronger; data suggests human intervention is assisting this.

Another piece of advice - do not trust western medical practitioners when it comes to malaria - they are not familiar with it, they have not studied it, and they do not believe you when you tell them it could be malaria (this is a generalization, but a good rule of thumb.) A Kenyan friend of English decent, who lived in Japan, was visiting his mother in Kenya. He contracted malaria unbeknownst and returned to Japan. Within a week he was in the hospital. A week later he was dead. Malaria is no joke, but it is easily curable with a bit of sulfur. (P.S. If you are allergic to sulfur, I suggest you vacation in the Hamptons).

Good luck. If anyone has seen information on the FDA/Peace Corps testing for meflaquine, please send it along. Thank you.
