Description
Viagra is a branded prescription medicine containing sildenafil. It is used for erectile dysfunction in adult men.
How does Viagra work?
Viagra helps increase blood flow to the penis during sexual stimulation. It does not increase sexual desire and does not cause an automatic erection.
How to take Viagra
Take Viagra exactly as prescribed. Swallow one tablet whole with water before anticipated sexual activity.
- It is usually taken around one hour before sex.
- Do not take more than one dose in 24 hours.
- A heavy or high-fat meal may delay the effect.
- Avoid grapefruit juice and excessive alcohol.
- Do not combine it with generic sildenafil or another erectile dysfunction medicine unless the prescriber has instructed you to do so.
What to expect
The effect commonly begins in around 30 to 60 minutes, although this varies. Viagra can be taken up to four hours before sex. Sexual stimulation is required.
Viagra and generic sildenafil
Both contain sildenafil. The branded product has its own licensed formulation, appearance and packaging. The prescriber may discuss whether branded or generic treatment is appropriate.
