Definition
Larium is a former brand name for mefloquine, an antimalarial drug used to prevent and treat malaria. As mefloquine, it interferes with parasite growth. Larium required careful consideration due to potential neuropsychiatric side effects. It was often prescribed for travelers to malaria-prone regions who could not tolerate other antimalarial drugs. Think of it as a choice for malaria prevention, though alternatives are often preferred today because of its side effects.
