Do not use this medication if you are allergic to mefloquine or similar medications such as quinine (Qualaquin) or quinidine (Quinaglute, Quinidex, Quin-Release).
You should not use this medication to prevent malaria if you have a recent history of seizures, depression, anxiety, or a psychiatric illness such as schizophrenia. However, your doctor may prescribe mefloquine to treat malaria even if you do have any of these conditions.

If you are taking this medicine to prevent malaria, start taking it 1 week before entering an area where malaria is common.

If you stop taking the medicine early for any reason, contact a healthcare professional about another form of malaria prevention.
If you are taking this medicine to treat malaria, the usual dose is 5 tablets at one time as a single dose.

In addition to taking mefloquine, use protective clothing, insect repellents, and mosquito netting around your bed to further prevent mosquito bites that could cause malaria.
