Artemether and Lumefantrine

WHY is this medicine prescribed?

The combination of artemether and lumefantrine is used to treat certain kinds of malaria infections (a serious infection that is spread by mosquitoes in certain parts of the world and can cause death). Artemether and lumefantrine should not be used to prevent malaria. Artemether and lumefantrine is in a class of medications called antimalarials. It works by killing the organisms that cause malaria.

HOW should this medicine be used?

The combination of artemether and lumefantrine comes as a tablet to take by mouth. It is usually taken twice a day for 3 days as instructed by your doctor. Always take artemether and lumefantrine with food. If you are not able to eat, contact your doctor. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take artemether and lumefantrine exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor.

If you have trouble swallowing the tablets, they may be crushed and mixed with 1 or 2 teaspoons of water in a clean container. Drink the mixture right away. Rinse the glass with more water and swallow the entire contents.

You may vomit soon after you take the medication. If you vomit within 1 to 2 hours after you take artemether and lumefantrine, you should take another full dose of artemether and lumefantrine. If you vomit again after taking the extra dose, call your doctor.

You should begin to feel better during the first few days of treatment with artemether and lumefantrine. If your symptoms do not improve or get worse, call your doctor. Also call your doctor if you have a fever, chills, muscle pain, or headache soon after you finish your treatment. This could be a sign that you still are infected with malaria.

Take artemether and lumefantrine until you finish the prescription, even if you feel better. If you stop taking artemether and lumefantrine too soon or skip doses, your infection may not be completely treated and the organisms may become resistant to antimalarials.

What should I know about STORAGE and DISPOSAL of this medication?

Keep this medication in the container it came in, tightly closed, and out of reach of children. Store it at room temperature and away from excess heat and moisture (not in the bathroom).

Unneeded medications should be disposed of in special ways to ensure that pets, children, and other people cannot consume them. However, you should not flush this medication down the toilet. Instead, the best way to dispose of your medication is through a medicine take-back program. Talk to your pharmacist or contact your local garbage/recycling department to learn about take-back programs in your community. See the FDA's Safe Disposal of Medicines website (https://goo.gl/c4Rm4p) for more information if you do not have access to a take-back program.

It is important to keep all medication out of sight and reach of children as many containers (such as weekly pill minders and those for eye drops, creams, patches, and inhalers) are not child-resistant and young children can open them easily. To protect young children from poisoning, always lock safety caps and immediately place the medication in a safe location — one that is up and away and out of their sight and reach. https://www.upandaway.org
