Who qualifies for Sildenafil

Our EU-licensed doctors carefully evaluate your medical history to determine if Sildenafil is suitable. They look for specific criteria to ensure your safety and the effectiveness of the treatment. Generally, Sildenafil is prescribed to adult men experiencing erectile dysfunction (ED). However, certain conditions may make Sildenafil inappropriate, such as severe heart problems, uncontrolled high or low blood pressure, recent stroke or heart attack, or specific liver or kidney conditions. It's crucial to disclose all existing health conditions and medications during your online consultation, especially nitrates, alpha-blockers, and other ED treatments, as these can interact dangerously with Sildenafil. Your doctor prioritises your health and will only issue a prescription if it is safe and medically appropriate.

What Sildenafil actually does (and doesn't do)

Sildenafil, the active ingredient in Viagra, helps men with erectile dysfunction achieve and maintain an erection firm enough for sexual activity. It works by increasing blood flow to the penis when you are sexually aroused. Sildenafil is a PDE5 inhibitor, meaning it relaxes blood vessels in the penis, allowing more blood to flow in. It does not create an erection on its own; sexual stimulation is still required for it to work. You typically take Sildenafil about 30-60 minutes before sexual activity, and its effects can last for 4-6 hours. It will not increase your libido or cure underlying causes of ED. It's a supportive treatment that helps you achieve an erection when naturally stimulated.

Side effects and when to stop

Like all medications, Sildenafil can cause side effects, though not everyone experiences them. Common side effects are usually mild and temporary, including headache, flushing of the face, nasal congestion, indigestion, and temporary visual disturbances (like blurred vision or a blue tinge to vision). More serious side effects are rare but require immediate medical attention. These include sudden vision loss, sudden hearing loss, or an erection that lasts longer than four hours (priapism). If you experience chest pain, dizziness, or nausea during sexual activity, stop and seek medical advice. Always follow your doctor's instructions and discontinue use if you experience any concerning or severe side effects.
