description: The skill advises clinicians to avoid prescribing topical antiandrogen agents (e.g., spironolactone or finasteride cream) for hirsutism in premenopausal women. Trigger phrases include “patient wants a topical cream for facial hair,” “considering eflornithine for hirsutism,” or “requests antiandrogen topical therapy.”

# Avoid topical antiandrogen therapy for hirsutism

## STEP 1 — Gather Information
Confirm hirsutism diagnosis (Ferriman–Gallwey score ≥8 in US White/Black women, ≥9 in Mediterranean/Hispanic/Middle Eastern, ≥6 in South Asian, ≥2–7 in East Asian), assess menstrual regularity, pregnancy/contraception status, prior cosmetic or pharmacologic treatments, and patient’s specific interest in topical antiandrogen preparations.

## STEP 2 — Rule In / Rule Out
Is the patient requesting or considering a topical antiandrogen agent for hirsutism?  
- **Yes** → proceed to Step 3.  
- **No** → no further action needed for this skill.

## STEP 3 — Classify or Stratify
Stratify by hirsutism severity (mild: FG 8‑15; moderate/severe: >15) and patient fertility intentions to guide overall management, but note that the recommendation against topical antiandrogen applies regardless of stratum.

## STEP 4 — Decide
Do **not** prescribe topical antiandrogen therapy. Instead, initiate first‑line pharmacologic therapy (combined estrogen–progestin oral contraceptive) or direct hair removal methods (laser/photoepilation or electrolysis) based on patient preference, contraception needs, and hair/skin type.

## Clinical Guardrails / Mimics / Pitfalls
Avoid topical antiandrogens due to limited efficacy, lack of robust RCT data, potential for systemic absorption, and risk of delaying effective therapy. Do not substitute topical agents for proven oral contraceptives, antiandrogens, or hair‑removal modalities. Be aware that eflornithine is **not** an antiandrogen (it inhibits ornithine decarboxylase) and is only adjunctive to laser/photoepilation, not a standalone hirsutism treatment.

## Concrete Clinical Example
A 24‑year‑old woman presents with mild facial hirsutism (FG score 10), regular menses, and requests a topical spironolactone cream after reading online. The clinician confirms no pregnancy risk, explains the lack of evidence for topical antiandrogens, and prescribes a combined oral contraceptive (ethinyl estradiol 20 µg + levonorgestrel) while offering laser hair removal for faster cosmetic improvement.
