Who qualifies for Sildenafil

Sildenafil is a powerful medication, and our EU-licensed doctors carefully assess each patient to ensure it's safe and effective for you. They look for specific criteria, including a confirmed diagnosis of erectile dysfunction. You must be an adult male without certain contraindications. These include severe heart conditions, recent stroke or heart attack, low blood pressure, or specific eye conditions like NAION. It's also crucial that you are not taking nitrates or alpha-blockers, as combining these with Sildenafil can lead to a dangerous drop in blood pressure. Your doctor will review your full medical history and current medications during the consultation to determine if Sildenafil is the right treatment for you.

What Sildenafil actually does (and doesn't do)

Sildenafil, widely known as Viagra, works by increasing blood flow to the penis, making it easier to achieve and maintain an erection when you are sexually stimulated. It belongs to a class of drugs called PDE5 inhibitors. Essentially, it helps your body's natural response to sexual arousal by allowing the smooth muscles in your penis to relax, leading to better blood circulation. It does not create sexual desire or act as an aphrodisiac; you still need to be sexually aroused for it to work. Typically, Sildenafil starts working within 30 to 60 minutes, and its effects can last for about 4 to 6 hours. It's important to have realistic expectations: Sildenafil enhances your natural erectile function, it doesn't guarantee instant or continuous erections without stimulation.

Side effects and when to stop

Like all medications, Sildenafil can cause side effects. Most common are mild and temporary, including headaches, flushing (redness in your face), nasal congestion, indigestion, and altered vision (such as blurred vision or sensitivity to light). More serious side effects are rare but require immediate medical attention. These include sudden loss of vision, sudden decrease or loss of hearing, or an erection that lasts longer than 4 hours (priapism). If you experience any of these severe symptoms, stop taking Sildenafil and seek emergency medical care. Always discuss your full medical history and all current medications with the doctor, as Sildenafil can interact dangerously with certain drugs, especially nitrates, leading to a severe drop in blood pressure.
