Is Viagra safe?

Yes, Viagra (sildenafil) is generally safe when taken as prescribed.

Precautions to keep in mind

1. Avoid certain medications. Never take Viagra with nitrates or medications like riociguat. These combinations can cause dangerously low blood pressure. Other medications may require additional monitoring for side effects with Viagra.

2. Talk to your healthcare team about your health history. Having certain health conditions can make Viagra unsafe. For example, you may need to avoid Viagra if you’ve had a recent heart attack or stroke.

3. Be aware of potential vision and hearing changes. In rare cases, sildenafil can cause sudden vision or hearing loss. Tell your healthcare team right away if you notice any changes in your vision or hearing.

4. Know the signs of serious side effects. Get emergency medical care if you experience symptoms such as chest pain, trouble breathing, or an erection lasting more than 4 hours (priapism).

Make sure your healthcare team has your complete medication list (including supplements) and medical history before starting Viagra. They can discuss the potential risks and symptoms to watch for when taking it.
