Who qualifies for Sildenafil
Our EU-licensed doctors individually review every case. They assess your medical history, current health status, and any other medications you are taking to determine if Sildenafil is a safe and appropriate treatment for you. Factors like cardiovascular health, blood pressure, and liver function are carefully considered. The doctor looks for contraindications that might make Sildenafil unsuitable, ensuring your safety is paramount.
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, making it easier to achieve and maintain an erection. It does not cause an erection automatically; sexual arousal is still required. Sildenafil typically starts working within 30 to 60 minutes and its effects can last for about 4 to 6 hours. It is not a cure for erectile dysfunction but effectively manages its symptoms, allowing for satisfactory sexual activity.
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 (such as a bluish tinge to vision). More serious, but rare, side effects include a sudden decrease or loss of vision or hearing, and an erection that lasts longer than 4 hours (priapism). If you experience any severe or prolonged side effects, you must stop taking Sildenafil and seek immediate medical attention. Always discuss any concerns with your doctor.
