Cialis Precautions and Warnings

Some Cialis Warnings and Precautions

Here are some precautions and warnings to be aware of when taking Cialis:
 
  • There are several other medications that Cialis can interact with (see Cialis Drug Interactions).
     
  • If you have a heart or blood vessel disease (cardiovascular disease) or significant heart disease risk factors, there is an increased chance of serious side effects while taking Cialis. In rare cases, problems with the heart, brain, and blood vessels are seen in people on Cialis. These problems can lead to serious side effects such as heart attack, stroke, or sudden death.

(Click Cialis Side Effects for more information.)

  • In people taking Cialis or other PDE5 inhibitors, there have been rare cases of a condition called non-arteritic anterior ischemic optic neuropathy (NAION). This condition can lead to sudden loss of vision in one or both eyes. If you experience any loss of vision while taking Cialis, contact your healthcare provider immediately (see Cialis and Blindness).

 

  • There have been reports of Cialis causing hearing problems. Stop taking Cialis and immediately contact your healthcare provider if you notice a sudden decrease in or loss of hearing.
  •  

  • The FDA considers Cialis a pregnancy Category B medicine, meaning that while the drug has not been studied in pregnant women, it showed no negative effects on unborn babies in previous animal studies. However, Cialis is not licensed for use in female patients.
     
  • In rare cases, people on Cialis can experience a prolonged erection, which in some cases can be painful. If you experience an erection for longer than four hours while taking Cialis, contact your healthcare provider immediately.
     
  • Cialis does not provide any protection against sexually transmitted diseases (STDs).
