Who qualifies for Viagra

Our EU-licensed doctors look for specific criteria to determine if Viagra is a safe and effective treatment for you. Generally, doctors consider your overall health, medical history, and any current medications. Conditions like severe heart disease, uncontrolled high blood pressure, or certain eye problems may prevent a prescription. The doctor will assess if you have erectile dysfunction and if there are any contraindications that make Viagra unsuitable. Your safety is the priority.

What Viagra actually does (and doesn't do)

Viagra (sildenafil) is a phosphodiesterase-5 (PDE5) inhibitor. It works by increasing blood flow to the penis, making it easier to achieve and maintain an erection when you are sexually stimulated. It does not cause an erection on its own; sexual arousal is still required. Viagra typically takes effect within 30-60 minutes and lasts for about 4-6 hours. It will not cure erectile dysfunction, but it effectively treats the symptoms. It also won't increase your libido or provide protection against sexually transmitted infections.

Side effects and when to stop

Like all medications, Viagra can cause side effects. Common ones include headache, facial flushing, nasal congestion, and indigestion. Less common but more serious side effects can occur, such as sudden vision loss, sudden hearing loss, or an erection lasting longer than four hours (priapism). If you experience any severe or persistent side effects, stop taking Viagra and seek immediate medical attention. Always discuss your full medical history and all current medications with your doctor to avoid adverse reactions, especially if you are taking nitrates for chest pain, as this combination can cause a dangerous drop in blood pressure.
