Finasteride Side Effects (Nuksanat)
Finasteride (Propecia) is generally safe when taken at the correct dose under doctor supervision. However, it has some important side effects that every patient should be aware of — particularly sexual side effects and post-finasteride syndrome.
Common Side Effects (Aam Nuksanat)
- Decreased libido
- Erectile dysfunction (mardana kamzori)
- Ejaculation disorders
- Decreased semen volume
These side effects are generally mild and may resolve over time in some patients. However, they should always be reported to a doctor.
Uncommon Side Effects (Ghair Aam)
- Breast tenderness or enlargement in men (gynecomastia)
- Skin rash
Serious Side Effects (Sanjeedah Nuksanat)
- Male breast cancer (rare) — any breast lump or nipple discharge should be reported to a doctor immediately
- Depression, anxiety, suicidal ideation — reported under post-finasteride syndrome; seek help immediately
- Post-finasteride syndrome — persistent sexual dysfunction, depression, or cognitive issues after stopping the medicine
- Severe allergic reaction — swelling of face/lips/tongue/throat, difficulty breathing — go to the emergency room immediately
Post-Finasteride Syndrome (PFS) — Zaroori Maloomat
Post-finasteride syndrome is a condition in which symptoms persist even after stopping finasteride:
- Persistent sexual dysfunction (ED, decreased libido)
- Depression or emotional numbing
- Cognitive issues ("brain fog")
This syndrome is controversial and does not occur in all patients, but documented cases exist. If you experience this, do not struggle alone — see a doctor immediately.
When to See a Doctor (Kab Doctor Se Milna Zaroori Hai)
- Persistent sexual side effects after stopping finasteride
- Any breast lump or nipple discharge in men
- Depression or suicidal thoughts — contact emergency services or a doctor immediately
- Signs of severe allergic reaction
Warnings and Precautions (Ihtiyat)
- Women — never handle crushed/broken tablets (teratogenic risk — male fetal malformation)
- Children — finasteride is strictly not for children
- Mental health monitoring — required both during use and after stopping the medicine
