Who qualifies for Finasteride

When you consult with an EU-licensed doctor for Finasteride, they carefully assess your medical history and current health. They look for specific criteria to ensure Finasteride is safe and effective for you. This includes reviewing your symptoms, any existing medical conditions, and other medications you might be taking. Finasteride 1mg is typically prescribed for male pattern baldness, while Finasteride 5mg is for benign prostatic hyperplasia (BPH). The doctor will determine the appropriate dosage if they find treatment suitable for your specific needs. Contraindications and potential drug interactions are thoroughly checked to ensure your safety.

What Finasteride actually does (and doesn't do)

Finasteride is a medication that works by inhibiting an enzyme called 5-alpha reductase. This enzyme converts testosterone into dihydrotestosterone (DHT), a hormone that plays a key role in both male pattern baldness and benign prostatic hyperplasia (BPH). By reducing DHT levels, Finasteride helps to slow down hair loss and, in some cases, promote hair regrowth for male pattern baldness (1mg dosage). For BPH (5mg dosage), it helps to shrink the enlarged prostate gland, alleviating urinary symptoms. It's important to understand that Finasteride does not cure these conditions; its effects are maintained only as long as you continue taking the medication. You can expect to see results for hair loss typically after several months of consistent use, while BPH symptom improvement may also take a few months.

Side effects and when to stop

Like all medications, Finasteride can have side effects. Common side effects for both 1mg and 5mg dosages may include decreased libido, erectile dysfunction, and a decrease in ejaculate volume. Less common but more serious side effects can include depression and, rarely, breast tenderness or enlargement. If you experience any severe or concerning side effects, such as persistent mood changes, breast lumps, or significant pain, you should stop taking Finasteride and consult a doctor immediately. Your Hi-Doctor EU-licensed doctor will discuss potential side effects with you during your consultation to ensure you are fully informed.
