Finasteride is a prescription-only tablet used to treat male pattern hair loss (androgenetic alopecia). It works by blocking the action of an enzyme (5-alpha-reductase) that converts testosterone into dihydrotestosterone (DHT). Lowering DHT levels helps to reduce hair thinning and can encourage hair regrowth on the scalp.

Common (usually mild/temporary):

• Decreased libido, erectile dysfunction, reduced semen volume

• Breast tenderness or enlargement

• Mood changes (including low mood)

​

Serious - seek medical advice promptly:

• Breast changes (lump, pain, nipple discharge)

• Allergic reactions (swelling of lips/face, rash, itching, hives)

• Persistent sexual side effects or significant mood changes

​

Finasteride can affect PSA blood tests (for prostate checks). Tell your doctor you take finasteride so results can be interpreted correctly.
