|02018055||LARIAM 250MG TABLET|
Mefloquine belongs to the class of medications called antimalarials. Mefloquine is used to treat and prevent malaria infections caused by certain types of parasites.
Malaria is an infection caused by a group of parasites called Plasmodia that enter the blood through bites from infected mosquitoes. The parasites first enter and destroy red blood cells, then they reproduce within the liver and are released into the blood. Mefloquine does not prevent the mosquitoes from biting or prevent the parasite from reproducing in the liver. Mefloquine works by destroying the parasite after it is released from the liver into the blood.

The dose of mefloquine for treatment of malaria is based on body weight (20 mg/kg to 25 mg/kg for those with no immunity, and 15 mg/kg for those with partial immunity). The total dose is taken all at once or in 2 to 3 doses spaced 6 or 8 hours apart to reduce the occurrence or severity of side effects. If a person vomits less than 30 minutes after receiving the medication, a full additional dose should be taken as instructed by your doctor. If vomiting occurs 30 to 60 minutes after the dose, an additional one-half dose should be taken as instructed by your doctor.
