A 30-year-old multiparous woman wants a long-acting reversible progestin-only contraceptive but refuses an intrauterine device. She receives depot medroxyprogesterone acetate. What is the standard dose and injection interval?

• A 50 mg intramuscularly every 6 weeks
• B 100 mg intramuscularly every 8 weeks
• C 150 mg intramuscularly every 12 weeks ✓
• D 300 mg intramuscularly every 16 weeks

Explanation

Depot medroxyprogesterone acetate is given as 150 mg by deep intramuscular injection every 12 weeks (3 months); the subcutaneous preparation is 104 mg at the same interval. It works mainly by suppressing ovulation. The other dose-interval combinations correspond to no standard product; norethisterone enanthate, the other injectable used in India, is 200 mg given every 8 weeks, which is the trap some students pick.
