Finasteride Side Effects: What You Should Know Before Starting

Are you looking to get a Finasteride prescription online in Spain or another EU country? You've come to the right place. An EU-licensed doctor can review your case online, and if they find treatment appropriate, you receive a prescription in under 24 hours. The online consultation costs a flat €25, and your prescription is valid at any pharmacy across the EU.

How it works — get your Finasteride prescription in 4 steps

  1. Fill out our secure online medical questionnaire. It takes just 2–3 minutes.
  2. A licensed EU doctor privately reviews your medical information.
  3. If the doctor finds Finasteride appropriate for you, you receive a REMPE electronic prescription within 24 hours. It's delivered to your private account and by email.
  4. Pick up your medication at any EU pharmacy – whether you're in Portugal, Italy, France, Germany, or elsewhere.

Who qualifies for Finasteride

When you seek a Finasteride prescription EU wide, our doctors carefully assess your medical history. Finasteride is primarily for men experiencing male pattern baldness (androgenetic alopecia). The doctor looks for specific criteria to ensure it's safe and effective for you. They consider your age, the pattern and extent of your hair loss, and any existing medical conditions or medications you are currently taking. Finasteride is not suitable for women or children. Contraindications include hypersensitivity to the active substance and certain liver conditions. The doctor always makes the final decision based on your individual health profile.

What Finasteride actually does (and doesn't do)

Finasteride works by targeting the root cause of male pattern baldness. It's a 5-alpha-reductase inhibitor that reduces the conversion of testosterone into dihydrotestosterone (DHT). DHT is the hormone responsible for shrinking hair follicles, leading to thinning hair and eventual hair loss. By lowering DHT levels in the scalp, Finasteride can slow down hair loss and, for many men, stimulate new hair growth. It's important to understand that Finasteride is not a cure-all; it addresses the hormonal aspect of hair loss. You won't see results overnight; consistent use over several months (typically 3–6 months) is needed to observe significant changes, and results can vary. It does not prevent other types of hair loss not related to DHT.

Side effects and when to stop

Like all medications, Finasteride can have side effects, though most men tolerate it well. Common side effects, usually mild and reversible, include decreased libido, erectile dysfunction, and ejaculation disorders. Less common side effects can involve breast tenderness or enlargement (gynecomastia), skin rash, or mood changes, such as depression or anxiety. If you experience persistent or concerning side effects, it's crucial to consult your doctor. They can assess whether these symptoms are related to Finasteride and advise if you should adjust the dosage or stop the medication. Most side effects resolve after discontinuing treatment.
