Short-course standard dose primaquine treatment (2022): To prevent relapse, an additional treatment option of using primaquine 0.5 mg/kg/day for seven days is recommended to treat P. vivax or P. ovale malaria in children and adults (except pregnant women, infants aged < 6 months, women breastfeeding infants aged < 6 months, women breastfeeding older infants unless they are known not to be G6PD deficient, and people with G6PD deficiency).

Notes and Remarks
Remark:
- As recommended previously, the G6PD status of patients should be used to guide administration of primaquine for preventing relapse.
- A shorter regimen can lead to better adherence compared to the standard 14-day regimen and thus to fewer relapses.
Practical info
- Health facilities should continue to monitor for vomiting, anaemia, haemolysis and adherence to treatment.
- Safety monitoring is critical, so strengthening of pharmacovigilance systems is generally needed.
- Surveillance for risk of false-negative results with G6PD tests and for lack of G6PD testing is essential.
