A forum horror story is not your baseline. Photograph; do not hide symptoms from the clinician.

U.S. 1 mg labels discuss sexual adverse events. Causation, persistence after stop, and β€œPFS” debates are clinical and controversial β€” HairBase will not invent a PMID. Related: finasteride-and-fertility β€” different URL.

Do not double minoxidil as a sexual AE workaround. Do not mash 5 mg prostate tablets.

Acute mood crisis or inability to urinate is care now. This is not medical advice.

Pregnancy warning: Finasteride and dutasteride can harm a developing male fetus. Do not take or handle them if pregnant or possibly pregnant.

FAQ

How common is it?

Labels describe a minority. This page is not a new epidemiology paper.

Will it reverse if I stop?

Ask the prescriber. This page is not a stop protocol.

Same as fertility page?

Related 5AR family, different URL. This file is sexual AE literacy.

More foam instead?

Topical minoxidil is another labelled story. Do not invent a swap without a clinician.

Not medical advice. General education only; it does not replace diagnosis or treatment by a licensed professional. Figures such as 1 mg or 5% are labelled strengths you may see in your country β€” not a dosing instruction. Consult a board-certified dermatologist before starting, stopping or changing any treatment.

⚠️ When to see a doctor β€” don’t self-treat

  • Sudden patchy or circular bald spots
  • Redness, scaling, pus, pain or itch (possible scarring alopecia β€” treat urgently)
  • Broken hairs or rapid loss
  • Loss with body-wide signs (weight loss, fatigue, cycle changes, acne, extra hair)
  • Loss right after a new medication
  • Any hair loss in a child
