Mefloquine (Lariam) Action, formerly Lariam Action USA, is an information and support service for people who have questions about the effects of the antimalarial drug mefloquine (Lariam®). Founded in January 1997, Mefloquine (Lariam) Action is a volunteer organization with a world-wide network of sufferers and activists, including but not limited to civilians, active duty military personnel and veterans, returned Peace Corps volunteers, and families of all these contingents.

We are the founding member of the Coalition for Antimalarial Drug Safety (CADS), which includes individuals and “Mefloquine/Lariam Action” groups in other countries.
