How it works — get your Finasteride prescription in 4 steps

2. A licensed EU doctor reviews your case in private. An EU-licensed doctor assesses your information and determines if Finasteride is suitable for you.
3. If appropriate, you receive a REMPE electronic prescription within 24 hours. Your valid prescription is delivered to your private account and by email.
4. Pick up your medication at any EU pharmacy. Present your REMPE prescription at any pharmacy in the EU (e.g., Spain, Portugal, Italy, France, Germany).

Who qualifies for Finasteride

Finasteride is a prescription medication for male pattern baldness (androgenetic alopecia). When you consult with our EU-licensed doctors, they look for specific criteria to ensure Finasteride is safe and effective for you. This includes your medical history, current health status, and the pattern of your hair loss. Finasteride is generally prescribed for men, and contraindications include known hypersensitivity to the drug or its components. The doctor always reviews your individual case to determine if Finasteride is the appropriate treatment.

What Finasteride actually does (and doesn't do)

Finasteride works by blocking the conversion of testosterone into dihydrotestosterone (DHT) — a hormone that contributes to hair follicle shrinkage and hair loss in genetically susceptible men. By reducing DHT levels in the scalp, Finasteride can slow down hair loss and, for some, stimulate new hair growth. While effective, it's not a magic bullet. You need consistent use, and results are not immediate; typically, you will notice changes within 3–6 months, with full effects possibly taking up to a year. It primarily targets the crown and mid-scalp areas and does not cure baldness, but rather manages it. If you stop taking Finasteride, hair loss will likely resume.

Side effects and when to stop

Like all medications, Finasteride can have side effects, though they are usually mild and uncommon. The most common reported side effects include sexual dysfunction (decreased libido, erectile dysfunction, ejaculation disorders), which typically resolve upon stopping the medication. Some men also report mood changes, including depression or anxiety, breast tenderness, or rash. It's crucial to discuss any concerns with your doctor. If you experience persistent or severe side effects, you should stop the medication and contact your doctor immediately. Medical honesty builds trust, and our doctors ensure you are fully informed.
