Your doctor has found that you have malaria and so has prescribed Artesunate Amodiaquine Winthrop.

It is indicated only for the treatment of so called uncomplicated malarial attacks due to Plasmodium falciparum (a particular type of malaria parasite) against which the medicine is active.

For complete cure it is important that you complete the prescribed dose as advised by your doctor, pharmacist or health care worker.
