Cialis

When and How to Take It

Here are some general guidelines for when and how to take Cialis:
 
  • The medication comes in tablet form. It can be taken just as needed, usually one hour before sexual activity (no more than once a day). It can also be taken every day, without regard to timing of sexual activity ("once-daily Cialis").

 

 

  • Take your Cialis dosage with a glass of water. You may take it with or without food.

 

  • For Cialis to work properly, you have to take it as prescribed. The medication will not work if you stop taking it.
  •   

Dosage Information

The dose of Cialis your healthcare provider recommends will vary, depending on a number of factors, including:
 
  • The medical condition being treated
  • Other medical conditions you may have
  • Other medications you may be taking.
     
As always, do not adjust your dose unless your healthcare provider specifically instructs you to do so.

Side Effects of Cialis

As with any medicine, side effects can occur with Cialis. However, not everyone who takes the drug will experience side effects. In fact, most men tolerate it well. If people do develop side effects, in most cases, they are minor, meaning they require no treatment or are easily treated by you or your healthcare provider.
 
The most common side effects include:
 
  • Headache
  • Indigestion (dyspepsia)
  • Back pain
  • Muscle pain (myalgia)
  • Nasal congestion
  • Facial flushing
  • Pain in the arms or legs.

 

If you have cardiovascular disease or significant heart disease risk factors, there is an increased chance of serious problems related to your heart, brain, and blood vessels. These problems can lead to dangerous side effects, such as a heart attack, stroke, or sudden death.
 
Also, there have been rare cases of a condition called non-arteritic anterior ischemic optic neuropathy (NAION) in people taking Cialis. This condition can lead to sudden loss of vision in one or both eyes. If you experience any loss of vision while taking this medicine, contact your healthcare provider immediately (see Cialis and Blindness).
