Important safety information.
Viagra has been shown to successfully treat ED in many men. But remember, no medicine is for everyone. If you use nitrate drugs, often used to control chest pain (also known as angina) don’t take Viagra as this can lower your blood pressure to unsafe levels.10
Remember to discuss your general health status with your GP to ensure that you are healthy enough to engage in sexual activity.
If you experience chest pain, nausea, or any other discomforts during sex or an erection that lasts longer than 4 hours, seek immediate medical help.
The most common side effects of Viagra are headache, facial flushing, and upset stomach. Less commonly bluish vision, blurred vision, or sensitivity to light may briefly occur.10
