Viagra is the most popular medication for erectile dysfunction, and is safe and effective for most men. However, it can cause side effects for less than 2% of men who use it. These side effects usually aren’t serious and most go away after a few hours.

If you’re worried about getting side effects from Viagra, we have a few tips for keeping your risk low and a doctor can help you find the right dose for you.

How to avoid side effects 

1.      Get a prescription from your GP or online doctor.

You doctor will check and make sure Viagra is suitable for you before prescribing your treatment. If you have any medical conditions or are taking any other medication, you may be at an increased risk of side effects.
 
2.      Don’t drink too much alcohol.

Alcohol increases the risk of certain side effects, such as low blood pressure and dizziness. It also reduces your ability to get an erection. Avoiding alcohol will help you minimise your risk of side effects and help you get the most from your medication.
 
3.      Don’t take more Viagra than you have been prescribed.

You should never exceed the dosage that your doctor has prescribed. Consult your doctor if you feel that the dosage you are taking is not high enough.
 
4.      Don’t mix Viagra with recreational drugs.

Avoid using recreational drugs during your treatment with Viagra – some illegal or ‘legal high’ drugs interact with Viagra and taking them can be dangerous.
 
5.      If you experience side effects, try a lower dosage.

If you suffer from side effects you may benefit from trying a lower dosage. You can also take the tablet with food. It will take longer to take effect when taken alongside a meal but will also be less likely to cause certain side effects.
