Who is this for?
What is this drug?
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.
What is it used for?
Malaria (including uncomplicated malaria caused by the most common and dangerous type of malaria parasite found in Nigeria)
Browse by condition
How it works
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.

How to take this drug
For adults, the usual dose is based on your body weight — typically 2 to 4 tablets taken once a day for 3 days. Take it on an empty stomach (at least 3 hours before or after eating) with a glass of water. Do not take it with food as this can increase side effects. Popular Nigerian brands include D-Artepp, Artexaten, and Dipakso — always follow the dosage instructions on your specific pack or as directed by your pharmacist or doctor.
What if I Miss a Dose?
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.
What to watch out for
Always complete the full 3-day course even if you start feeling better after the first day — 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 — you may need a different treatment.
