Who qualifies for Sildenafil

Our EU-licensed doctors carefully review your medical history to determine if Sildenafil is right for you. They look for specific health indicators and potential contraindications to ensure your safety and the treatment's effectiveness. Generally, Sildenafil is considered for adult men experiencing erectile dysfunction. However, certain conditions may make Sildenafil unsuitable, such as severe heart conditions, recent stroke or heart attack, low blood pressure, or certain eye conditions. It's crucial to disclose all existing health issues and medications during your online consultation. The doctor will assess if Sildenafil is a safe and appropriate treatment option based on your individual profile.

What Sildenafil actually does (and doesn't do)

Sildenafil works by increasing blood flow to the penis, which helps you achieve and maintain an erection when you are sexually aroused. It belongs to a class of medications called PDE5 inhibitors. When you take Sildenafil, it helps relax the blood vessels in your penis, allowing more blood to flow in. This mechanism only works in response to sexual stimulation; Sildenafil itself does not cause an erection without it. Its effects typically last for about 4–6 hours. It's important to understand that Sildenafil treats the symptoms of ED; it does not cure the underlying cause of erectile dysfunction. It also does not protect against sexually transmitted infections.

Side effects and when to stop

Like all medications, Sildenafil can cause side effects. Common side effects include headache, flushing, nasal congestion, indigestion, and temporary visual disturbances like blurred vision or a blue tint to your vision. These are usually mild and temporary. More serious, though rare, side effects can include sudden vision loss, hearing loss, or an erection lasting longer than 4 hours (priapism). If you experience any of these serious side effects, seek immediate medical attention. Always stop taking Sildenafil and consult a doctor if you experience chest pain, severe dizziness, or an allergic reaction. Our doctors will discuss potential side effects with you during your consultation to ensure you are fully informed.
