How it works — get your Sildenafil prescription in 4 steps

1. Fill the online medical questionnaire (2–3 minutes). This secure form gathers essential health information for the doctor.
2. A licensed EU doctor reviews your case in private. They assess your medical history and current health to determine if Sildenafil is appropriate for you.
3. If the doctor finds treatment appropriate, you receive a REMPE electronic prescription within 24 hours. This prescription is delivered directly into your private Hi-Doctor account and by email.
4. Pick up your medication at any EU pharmacy. Your prescription is valid across the European Union, making it easy to get your medication locally.

Who qualifies for Sildenafil

When you complete your online medical questionnaire, the EU-licensed doctor looks for specific criteria to ensure Sildenafil is safe and effective for you. They review your medical history for conditions such as heart disease, uncontrolled high blood pressure, or liver/kidney problems. They also check for any medications you are currently taking that might interact with Sildenafil, particularly nitrates. The doctor assesses your overall health to confirm that Sildenafil is appropriate for your individual case.

What Sildenafil actually does (and doesn't do)

Sildenafil, commonly known by its brand name Viagra, belongs to a class of medications called PDE5 inhibitors. It works by increasing blood flow to the penis when you are sexually stimulated. This helps you achieve and maintain an erection firm enough for sexual intercourse. Sildenafil does not automatically cause an erection; sexual arousal is still necessary. Its effects typically last for about 4–6 hours after taking the pill, giving you a window of opportunity for sexual activity. It does not cure erectile dysfunction, but it effectively treats the symptoms.

Side effects and when to stop

Like all medications, Sildenafil can have side effects. Common ones include headache, flushing, nasal congestion, and mild dizziness. More rarely, some men experience visual disturbances. Serious side effects are uncommon but can include a prolonged erection (priapism) lasting more than 4 hours, or sudden vision or hearing loss. If you experience any severe or concerning side effects, stop taking Sildenafil immediately and seek medical attention. Always discuss your full medical history with the doctor to ensure Sildenafil is safe for you, especially if you have heart conditions or take other medications.
