What is Lariam
MefloquineThe Generic name of this drug
Treatment SummaryMalaria is a serious disease found in many parts of the world that is caused by a parasite. In the last two decades, the number of deaths from malaria has decreased by 60%. It is most dangerous for people who are not living in malaria-endemic areas, children under 5, pregnant women, refugees, and immigrants visiting their country of origin. Mefloquine (also known as Lariam) is a drug used to prevent and treat malaria. It was developed by the Walter Reed Army Institute of Research in the 1960s and 1970s, and was approved by the FDA in 1989. There have been reports of serious neurological

Effectiveness
How Lariam Affects PatientsWhen a mosquito carrying malaria parasites bites a human, the parasites enter the bloodstream. These parasites then move to the liver, where they grow and burst open, releasing thousands of merozoites that invade red blood cells. Mefloquine is a drug used to prevent and treat malaria. It works by killing the malaria parasites in the blood.
How Lariam works in the bodyWe don't know exactly how mefloquine works, but some researchers think it targets proteins in the Plasmodium falciparum, a type of malaria. By targeting these proteins, mefloquine is able to stop the malaria from reproducing, killing it in the process. Some research suggests this is true, but more is needed to confirm it.

Lariam Reviews: What are patients saying about Lariam?
5Patient Review
7/7/2010 My wife and I took Larium for two years while we were in Ethiopia with the Peace Corps. We had no problems whatsoever. The Peace Corps said it had only been cleared for six months of usage, but they knew of no problems with longer-term use.
4.3Patient Review
3/16/2020 I've been taking this medication on an as-needed basis since 1989 without any problems. I have not contracted malaria, although I know some of my friends have had issues with it.
3.3Patient Review
3/11/2008 My father-in-law took this before going to Africa and, upon returning, started having psychotic episodes due to the hallucinations caused by the medication. He had no history of mental illness prior to taking this drug. Do not take this under any circumstances!
3Patient Review
3/10/2011 I've gotten migraines since I stopped taking this medication. I'm not sure what the long-term side effects are, but they're definitely something to be aware of.
