[Long-lasting neuropsychiatric side-effects following mefloquine prophylaxis. A case after six weeks of initiating and lasting six months].

Neuropsychiatric side-effects from mefloquine are well known. When used for prophylaxis, the side-effects have been claimed to be relatively rare, mild and transient, most often arising within two to three weeks, and in patients with a previous history of neuropsychiatric disorders. We here describe a case of severe neuropsychiatric side-effects arising six weeks after initiating mefloquine prophylaxis, requiring repeated hospitalization, and not resolving completely after six months, in a previously healthy 30 year-old female.
