Higher dose primaquine prevents relapse of P. vivax malaria, study finds

A higher dose of primaquine was significantly more effective at preventing relapse of Plasmodium vivax malaria than a smaller dose, according to study findings published in The New England Journal of Medicine.
The study was conducted in 2018 during malaria season in a city in the western Brazilian Amazon with a high prevalence of infection. It compared a primaquine dose of 7 mg per kg of body weight with a dose of 3.5 mg/kg, which is widely recommended in the Americas, according to Nathália N. Chamma-Siqueira, MSc, from the Evandro Chagas Institute, and colleagues.
