Primaquine alternative dosing schedules for preventing malaria relapse in people with Plasmodium vivax.
CONCLUSIONS: Trials available to date do not detect a difference in recurrence between the following regimens: 1) 0.5 mg/kg/day for seven days versus standard 0.25 mg/kg/day for 14 days; 2) high-standard 0.5 mg/kg/day for 14 days versus standard 0.25 mg/kg/day for 14 days; 3) 0.75 mg/kg/week for eight weeks versus high-standard 0.5 mg/kg/day for 14 days; 4) 1 mg/kg/day for seven days versus high-standard 0.5 mg/kg/day for 14 days. There were no differences detected in adverse events for Comparisons 1, 2 or 3, but there may be more serious adverse events with the high seven-day course in Comparison 4. The shorter regimen of 0.5 mg/kg/day for seven days versus standard 0.25 mg/kg/day for 14 days may suit G6PD-normal patients. Further research will help increase the certainty of the findings and applicability in different settings.
