Antimalarial (Artemisinin-based Combination Therapy - ACT)
Last reviewed July 2026
Who is this for?
Dihydroartemisinin/Piperaquine Phosphate is a combination antimalarial drug that contains two active ingredients which work together to kill the malaria parasite in your blood. Dihydroartemisinin acts fast to quickly reduce the parasites, while piperaquine stays in your body longer to clear out the remaining ones and prevent them from coming back.
Inhibits plasmodial protein synthesis and causes oxidative damage to the parasite by generating reactive oxygen species through interaction with heme, while piperaquine intercalates into parasitic DNA and inhibits nucleic acid synthesis, providing synergistic antimalarial activity against Plasmodium falciparum and other malaria parasites.
Malaria (including uncomplicated malaria caused by the most common and dangerous type of malaria parasite found in Nigeria)

If you miss a dose, take it as soon as you remember, as long as your next dose is not due very soon. If it is almost time for your next dose, skip the missed one and continue your normal schedule. Do not take a double dose to make up for the missed one. Make sure you still complete the full 3-day course.
Always complete the full 3-day course even if you start feeling better after the first day, as stopping early can make the malaria come back stronger. Buy only from licensed pharmacies, not from roadside vendors or unregistered shops, as fake antimalarials are common in Nigeria. If your symptoms do not improve after finishing the course or you develop a fever again, go back to your doctor, as you may need a different treatment.
Avoid taking this drug with other medicines that can affect your heart rhythm, such as chloroquine, halofantrine, or some antibiotics like erythromycin. Do not combine it with other artemisinin-based antimalarials (like Coartem/Lonart) at the same time. Avoid alcohol while on this medication as it can worsen dizziness and stomach upset.
