A woman opts for the injectable contraceptive depot medroxyprogesterone acetate (DMPA). What is the standard dose and dosing interval?
- A 50 mg intramuscularly monthly
- B 150 mg intramuscularly every 6 months
- C 150 mg intramuscularly every 3 months ✓
- D 104 mg orally every month
Correct answer: C. 150 mg intramuscularly every 3 months
Explanation
The standard DMPA regimen is 150 mg of medroxyprogesterone acetate given deep intramuscularly (gluteal or deltoid) every 3 months, ideally within the first 5 days of the cycle. The 104 mg preparation is a lower-dose formulation given SUBCUTANEOUSLY, not orally, which kills option D. Monthly injections are combination oestrogen-progestogen preparations, not DMPA.
