Viagra and Alcohol

Viagra is a popular treatment for erectile dysfunction in men, or the inability to achieve and maintain erections for sexual intercourse. It contains the active ingredient Sildenafil, which works by relaxing the muscles in the penis, thereby dilating the blood vessels and increasing the blood flow in the organ.

However, like most medications, Viagra has its side effects, which include, but are not limited to harmless ones:

  • Dizziness
  • Blurry vision
  • Visual disturbances
  • Hot flushes
  • Blocked nose
  • Nausea
  • Indigestion
  • Headaches

These are the most common side effects (between 1 in 10 to 1 in 100 people using Viagra) but not everyone gets the. Less common ones may affect 1 in 100 to 1 in 10,000 people:

  • Vomiting
  • Blood in the urine
  • Skin rashes
  • Nose bleeds
  • Rapid heartbeats
  • Muscle aches
  • Fainting
  • Eye irritation

More dangerous side effects are very rare:

  • Heart attack
  • Seizure
  • Stroke
  • Blistering skin
  • Painful and prolonged erections
  • Severe allergic reaction

How long the side effects last

Just as side effects can vary from person to person, the same goes for how long they can last. The most common ones are short-term and should disappear a while after taking the medication. 
If you have prolonged side effects, stop taking Viagra and seek medication attention.

Things to avoid taking with Viagra

There are certain prescription medications which react dangerously with Viagra and so should not be taken at the same time. These including drugs to treat heart disease, strokes, alpha blockers and those used to treat kidney and liver failure.
Mixing any other ED medications, alcohol, nitrate-based medication and recreational drugs with Viagra is not advisable and can have serious and potentially fatal consequences. 
If in doubt, speak to your GP about the different options their interactions with your existing prescriptions.

Lower the risks of side effects

  • Getting up slowly from sitting or lying down to avoid getting dizzy
  • Avoid alcohol as it can make it more difficult to achieve an erection
  • Take the tablets with food; taking it on an empty stomach can make the side effects worse
  • Lowering the dose will also reduce the side effects
