Under the National Vector Borne Disease Control Programme (NVBDCP), which of the following is the recommended dose of primaquine for radical cure of Plasmodium vivax malaria in an adult (after confirming normal G6PD status)?
- A 15 mg daily for 5 days
- B 15 mg daily for 14 days ✓
- C 0.25 mg/kg single dose
- D 0.5 mg/kg weekly for 8 weeks
Correct answer: B. 15 mg daily for 14 days
Explanation
Under NVBDCP, the standard radical cure for P. vivax in adults with normal G6PD status is primaquine 15 mg daily for 14 days to eliminate hypnozoites. Option A (5 days) is insufficient. Option C is the single-dose regimen used for P. gametocidal effect in falciparum malaria. Option D is the WHO alternative weekly regimen but not the standard NVBDCP recommendation.
