The preventive treatment of Plasmodium vivax relapse recommended by the World Health Organization is primaquine at a dose of 15 mg/day for 14 days, except for malaria cases from Asia and Oceania. Since 2006, CDC recommends the use of primaquine at 30 mg/day for 14 days. In France, all cases of malaria due to P. vivax are treated with 30 mg of primaquine. This systematically increased dosage needs to be evaluated according to epidemiological context. The aim of the study was to compare relapses after 14 days of primaquine at 15 or 30 mg/day. ⋯ There were no significant differences between primaquine at 15 or 30 mg/day for 14 days in the prevention of P. vivax relapses at 2, 3 and 6 months after primaquine treatment in French Guiana.
