Under India's National Family Planning Programme, the subcutaneous injectable contraceptive 'Antara' contains which drug and dose?

• A Medroxyprogesterone acetate 150 mg intramuscularly every 12 weeks
• B Etonogestrel implant 68 mg subdermally for 3 years
• C Norethisterone enanthate 200 mg intramuscularly every 8 weeks
• D Medroxyprogesterone acetate 104 mg subcutaneously every 13 weeks ✓

Explanation

Antara is DMPA subcutaneous 104 mg given once every 13 weeks (about 3 months); it was introduced into the national programme alongside Chhaya (centchroman) and the LNG-IUS. Option A describes the conventional intramuscular Depo-Provera preparation available commercially, not the programme product. Norethisterone enanthate is a separate two-monthly injection not branded Antara, and option B describes a subdermal implant, which is a different delivery system entirely.
