Available by prescription only, Lariam® (mefloquine hydrochloride) is a medicine approved to treat and prevent malaria. Lariam comes in the form of a tablet and is either taken as a one-time dose (to treat malaria) or on a weekly basis for several weeks (to prevent malaria).
When used to treat malaria, Lariam works by killing the parasite that causes this blood infection. Although most people tolerate the medication well, side effects are possible and may include vomiting, diarrhea, and dizziness.
You may not be able to safely take Lariam if you have certain medical issues, such as seizures or mental health problems. Make sure your healthcare provider is aware of any other medical conditions you may have, as well as any other medications you are taking, before using Lariam for malaria treatment or prevention.
