Antimalarial
Last reviewed July 2026
Who is this for?
Artemether is an antimalarial drug that works by killing the malaria parasite in your blood, stopping the infection from spreading in your body.
Inhibits malaria parasite protein synthesis and causes oxidative damage by generating reactive oxygen species following bioactivation of the artemisinin nucleus, leading to parasite death. Acts rapidly against both sexual and asexual forms of Plasmodium species, including multidrug-resistant strains.

Since this injection is given by a health worker on a schedule, missed doses are unlikely. However, if a dose is delayed, get to the hospital or clinic as soon as possible to continue treatment. Do not skip doses as this can make the malaria worse.
Always get artemether injection from a licensed pharmacy or hospital, and avoid buying from roadside vendors or unregistered shops, as fake antimalarials are common in Nigeria. Make sure a trained health worker gives the injection. Once you can eat and drink, your doctor should switch you to oral antimalarial tablets (like artemether-lumefantrine) to complete the full course; do not stop treatment early even if you feel better.
Avoid taking artemether with drugs that affect your heartbeat such as some antibiotics like erythromycin or heart medications. Grapefruit juice can increase the drug level in your body. Avoid alcohol during treatment as it can worsen side effects like dizziness and put extra stress on your liver.
Check your specific combination
Is it safe to take Artemether with your other drugs?
Artemether injection should only be used in pregnancy if the malaria is life-threatening and no safer alternative is available; always consult your doctor. It is not recommended during the first three months of pregnancy unless absolutely necessary. Breastfeeding mothers should also consult their doctor.
Store below 30°C in a cool, dry place away from direct sunlight and heat. Do not freeze. Keep out of reach of children. In hot Nigerian weather, avoid storing near windows or in cars where temperatures can get very high.
