How is Viagra taken?

Swallow 1 tablet whole with a glass of water or juice (avoid grapefruit juice) 1 hour before you want to have sex. It’s also best to take Viagra on an empty stomach as it may take longer to get into your system if you take it with food.

When will my erection happen and how long does it last?

It can take just 30 minutes to 1 hour for Viagra to begin to work. It is best to take it 1 hour before you want to have sex as it can sometimes take this long to work fully.

It will not give you an erection on its own, you also need to be turned on. The effects of Viagra can last up to 5 hours, but it usually starts to wear off after 2 or 3 hours.

When the effects wear off you should not take another Viagra within the same 24 hour period.

What are the side effects?

Common side effects of Viagra include:


  • headaches
  • dizziness
  • feeling sick
  • hot flushes
  • indigestion or heartburn
  • a change in vision
  • a stuffy nose

If you have any of these side effects it is safe to keep taking Viagra, but you should tell your doctor if you are worried or they do not go away over time.

Rare side effects of Viagra include:

  • chest pains
  • prolonged and sometimes painful erections
  • a sudden change or loss of vision
  • a serious skin reaction
  • seizures

You should stop taking Viagra and call a doctor right away if you get any of these rare side effects. You should get medical help right away if you have an erection that lasts more than 4 hours.

In which pack sizes is Viagra available?

You can buy boxes of 4, 8, 12, 16, or 28 tablets. The tablets are blue and diamond-shaped, marked PFIZER on one side and either VGR 25, VGR 50, or VGR 100 on the other depending on the dose you have.
