Minerva-35 for Acne: How Long Until Results?

Minerva-35 (norethindrone 0.5 mg / ethinyl estradiol 0.035 mg) is a combined oral contraceptive that can improve hormonal acne.

Timeline for Improvement

• 1–3 months: Initial reduction in inflammatory lesions.
• 3–6 months: Significant clearance typical.
• Up to 12 months: Maximal benefit; some need longer.

Why It Works

• Suppresses ovarian androgens.
• Increases SHBG → reduces free testosterone.
• Anti-androgenic progestin (norethindrone has mild androgenic activity; other pills like drospirenone are more anti-androgenic).

Adjunctive Measures

• Gentle cleanser 2×/day.
• Topical retinoid ± benzoyl peroxide.
• Non-comedogenic moisturizer/sunscreen.
• Dermatologist if severe (isotretinoin candidate).

Important

OCPs are not first-line for acne alone (contraception primary indication). Discuss risks (VTE, mood, libido) with provider. Not for use in pregnancy.
