Side effects

Avodart: Similar profile to finasteride. Some studies show slightly higher rate of sexual side effects, others show no difference. Smaller long-term safety dataset than finasteride.

Finasteride (Propecia): Most common: small (~2-4%) rate of sexual side effects in trials (decreased libido, ED, ejaculation issues). Rare: gynecomastia, mood changes. 'Post-finasteride syndrome' is a contested phenomenon with persistent side effects after discontinuation; baseline rate appears low.

Which should you choose?

Neither has a decisive headline-efficacy edge in the catalog data, so the deciding factors are usually tolerability, dosing, and cost. On cost and access, compare each drug's manufacturer direct-pay and insurance path — that often matters more month-to-month than the efficacy gap. Bring this comparison to a prescriber, who will match the drug to your history and titrate the dose.

This is editorial framing, not a prescription. The right choice depends on your medical history, insurance, and a clinician's evaluation.
