Finasteride: Uses, Side Effects, and What You Need to Know

When dealing with finasteride, a prescription medication that blocks the conversion of testosterone to dihydrotestosterone (DHT). Also known as Proscar or Propecia, it is commonly prescribed for two main conditions. The first is androgenic alopecia, a form of pattern hair loss that affects both men and women, where reducing DHT can slow or reverse thinning. The second is benign prostatic hyperplasia, an enlargement of the prostate gland that causes urinary symptoms; finasteride shrinks the gland by limiting DHT‑driven growth. In both cases the drug works by inhibiting 5‑alpha‑reductase, the enzyme that converts testosterone into the more potent DHT. This simple mechanism creates a cascade of effects: lower DHT levels → reduced hair follicle miniaturization → potential regrowth, and lower DHT → smaller prostate → easier urination.

Key Aspects of Finasteride Therapy

Finasteride’s effectiveness depends on dosage and adherence. For hair loss, a 1 mg daily tablet is typical, while prostate treatment often uses 5 mg per day. Starting the medication can trigger a short‑term shedding phase as weaker hairs fall out, making way for stronger ones later—a phenomenon many users mistake for failure. Side effects vary but commonly include reduced libido, erectile changes, and occasional mood shifts. Because the drug alters hormone pathways, doctors usually order baseline prostate‑specific antigen (PSA) tests and follow‑up labs to monitor prostate health and ensure no hidden issues arise. Women who are pregnant or may become pregnant must avoid handling crushed or broken tablets, as exposure to finasteride can affect fetal development.

Beyond the core uses, finasteride intersects with many other medication topics. If you’re juggling other prescriptions, understanding workplace accommodations for side effects becomes vital—especially under ADA guidelines. Comparing finasteride’s safety profile with other hormone‑modulating drugs, such as certain anti‑androgens or dopamine agonists, can help you weigh benefits against risks. Likewise, knowing how common over‑the‑counter compounds like aspirin or ibuprofen interact with hormone therapies can prevent unwanted bleeding or kidney stress.
