How it works — get your Sildenafil prescription in 4 steps

1. Fill the online medical questionnaire (2–3 minutes).
2. A licensed EU doctor reviews your case in private.
3. If appropriate, you receive a REMPE electronic prescription within 24 hours.
4. Pick up your medication at any EU pharmacy.

Who qualifies for Sildenafil

When you complete your online medical questionnaire, an EU-licensed doctor assesses your health profile to determine if Sildenafil or other ED medication is safe and appropriate for you. They look for:

• A confirmed diagnosis of Erectile Dysfunction.
• No significant heart conditions, uncontrolled high blood pressure, or recent stroke/heart attack.
• No severe liver or kidney problems.
• You are not taking nitrates (often used for chest pain) or riociguat (for pulmonary hypertension), as these can interact dangerously with Sildenafil.
• Other medications you are currently taking to check for potential contraindications.

Your doctor will ensure the treatment aligns with your overall health and medical history before issuing a prescription.

What Sildenafil actually does (and doesn't do)

Sildenafil, the active ingredient in Viagra, is a phosphodiesterase-5 (PDE5) inhibitor. It works by increasing blood flow to the penis when you are sexually aroused. This helps you achieve and maintain an erection firm enough for satisfactory sexual intercourse. It typically starts working within 30-60 minutes and its effects last about 4-6 hours.

What Sildenafil doesn't do: It does not create sexual arousal; you still need to be stimulated for it to work. It's not a cure for ED, but a treatment that helps manage symptoms. It also doesn't protect against sexually transmitted infections.

Side effects and when to stop

Like all medications, Sildenafil can cause side effects. Most are mild and temporary. Common side effects include headache, flushing, nasal congestion, indigestion, and visual disturbances (a bluish tinge to vision or increased sensitivity to light). Less common but more serious side effects include a sudden decrease or loss of vision or hearing, or an erection lasting longer than 4 hours (priapism).

When to stop and seek urgent medical attention: If you experience chest pain, sudden vision loss, sudden hearing loss, or an erection lasting more than 4 hours, stop taking Sildenafil and seek immediate medical help. Always discuss any concerns about side effects with your doctor.
