The World Health Organization currently recommends artemisinin-based combination therapy (ACT) for three days in the treatment of uncomplicated falciparum malaria. Artemisinin compounds are considered acceptable in the 2nd and 3rd trimester of pregnancy, but not in the 1st trimester. In severe malaria, parenteral artesunate or artemether are preferred in the 2nd and 3rd trimester. Quinine may be preferred in the 1st trimester, but a risk:benefit assessment is required and artesunate may be considered as a treatment option.
