Who qualifies for Viagra

Our EU-licensed doctors assess your medical history to ensure Viagra is safe and effective for you. They look for certain health conditions, current medications, and overall cardiovascular health. Contraindications like severe heart conditions, uncontrolled high blood pressure, or certain eye conditions mean Viagra is not appropriate. Always be honest in your medical questionnaire; it helps the doctor protect your health.

What Viagra actually does (and doesn't do)

Viagra (sildenafil) helps you achieve and maintain an erection when you are sexually stimulated. It works by increasing blood flow to the penis. It does not create sexual arousal itself, nor is it an aphrodisiac. An erection typically occurs 30–60 minutes after taking the pill and lasts for about 4 hours. It's important to understand that Viagra treats the symptoms of erectile dysfunction; it does not cure the underlying cause.

Side effects and when to stop

Like all medications, Viagra can cause side effects. Common ones include headaches, flushing, nasal congestion, and mild visual disturbances. More serious, but rare, side effects can include a sudden decrease or loss of vision or hearing, or an erection lasting longer than 4 hours (priapism). If you experience any severe side effects, or an erection lasting more than 4 hours, seek immediate medical attention. Always follow your doctor's instructions and stop taking Viagra if you experience concerning symptoms.
