Who qualifies for Sildenafil

Our EU-licensed doctors look for specific criteria to determine if Sildenafil is appropriate for you. Generally, Sildenafil is prescribed for men experiencing erectile dysfunction. Factors considered include your overall health, existing medical conditions, and any other medications you are currently taking. Doctors will assess for contraindications such as severe heart conditions, recent stroke or heart attack, low blood pressure, or use of nitrate medications. Your safety is our priority, and the doctor only issues a prescription if they find it medically appropriate for your individual health profile.

What Sildenafil actually does (and doesn't do)

Sildenafil, widely known as Viagra, helps men achieve and maintain an erection suitable for sexual activity. It belongs to a class of drugs called PDE5 inhibitors. When sexually stimulated, Sildenafil increases blood flow to the penis by relaxing blood vessels. This makes it easier to get an erection. It's important to understand that Sildenafil does not cause an erection on its own; sexual stimulation is still required. It typically starts working within 30 to 60 minutes and its effects can last for up to 4 hours. Sildenafil does not cure erectile dysfunction, nor does it increase sexual desire or 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 bluish tinge. These are usually mild and temporary. More serious, but rare, side effects include sudden vision loss, sudden hearing loss, or an erection lasting more than 4 hours (priapism). If you experience any severe side effects, stop taking Sildenafil immediately and seek urgent medical attention. Always inform the doctor reviewing your case about all your medical conditions and medications to minimise risks.
