What is used to treat falciparum malaria?
falciparum infection in the second and third trimesters can be treated with artemether-lumefantrine. Artemether-lumefantrine may be used during the first trimester if other treatment options are not available, and if the potential benefit is judged to outweigh the potential risks.

Why primaquine is given for 14 days?
Background. Plasmodium vivax infections are an important contributor to the malaria burden worldwide. The World Health Organization recommends a 14‐day course of primaquine (0.25 mg/kg/day, giving an adult dose of 15 mg/day) to eradicate the liver stage of the parasite and prevent relapse of the disease.

Is primaquine the same as chloroquine?
Chloroquine is a highly effective schizontocide, while primaquine has weaker asexual-stage activity (3) but is the only generally available drug with hypnozoitocidal properties, i.e., it kills dormant liver stage parasites and prevents relapse (radical cure) (1).
How do you give primaquine?
Primaquine phosphate should be administered concurrently in order to eradicate the exoerythrocytic parasites in a dosage of 1 tablet (equivalent to 15 mg base) daily for 14 days.
