Primaquine alternative dosing schedules for preventing malaria relapse in people with Plasmodium vivax

This review found no evidence for a difference in recurrence between the various regimens tested; more serious adverse effects may be seen with the high-dose (1mg/kg/day) 7-day course. The shorter regimen of 0.5 mg/kg/day for seven days may suit G6PD-normal patients.
