It is important that your doctor check your or your child's progress after treatment. This is to make sure that the infection is cleared up completely, and to allow your doctor to check for any unwanted effects.
If your or your child's symptoms do not improve within a few days or if they become worse, check with your doctor.
Tell your doctor if you or your child have used other medicines to treat your malaria infection. Using this medicine together with halofantrine (Halfan®), mefloquine (Lariam®), or quinine may increase the chance for more serious side effects.

Malaria is spread by the bites of certain kinds of infected female mosquitoes. If you are living in or will be traveling to an area where there is a chance of getting malaria, the following mosquito-control measures will help to prevent infection:
If possible, avoid going out between dusk and dawn because it is at these times that mosquitoes most commonly bite.
Wear long-sleeved shirts and long trousers to protect your arms and legs, especially from dusk through dawn when mosquitoes are out.
Apply insect repellant, preferably one containing DEET, to uncovered areas of the skin from dusk through dawn when mosquitoes are out.
If possible, sleep in a screened or air-conditioned room or under mosquito netting sprayed with insecticide to avoid being bitten by malaria-carrying mosquitoes.
Use mosquito coils or sprays to kill mosquitoes in living and sleeping quarters during evening and nighttime hours.
This medicine may decrease the effects of birth control pills or transdermal patches. To avoid an unwanted pregnancy, it is a good idea to use additional contraceptive measures with your pills or patches (eg, condoms, a diaphragm, or a contraceptive foam or jelly) while using this medicine.
