This is a summary of the most important information
about Cialis. For details, talk to your healthcare professional.
FDA ALERT [7/2005]: A small number of men have
lost eyesight in one eye some time after taking Cialis, Viagra, or
Levitra. This type of vision loss is called non-arteritic anterior
ischemic optic neuropathy (NAION). NAION causes a sudden loss of
eyesight because blood flow is blocked to the optic nerve.
We do not know at this time if Cialis, Viagra or Levitra causes
NAION. NAION also happens in men who do not take these medicines.
People who have a higher chance for NAION include those who:
FDA has approved new labels for Cialis, Viagra,
and Levitra to include information on possible eyesight loss (NAION).
Stop using Cialis, Viagra, or Levitra if you have a loss in your
eyesight. Get medical help right away.
This information reflects FDA�s current
analysis of data available to FDA concerning this drug. FDA intends
to update this sheet when additional information or analyses become
available.
What is Cialis?
Cialis is a prescription medicine taken by mouth for the treatment
of erectile dysfunction (ED) in men. ED is a condition where the
penis does not harden and expand when a man is sexually excited, or
when he cannot keep an erection. Cialis may help a man with ED get
and keep an erection when he is sexually excited. Cialis must be
used only under a doctor�s care.
Cialis does not:
-
cure ED
-
increase a man�s sexual desire
-
protect a man or his partner from sexually
transmitted diseases, including HIV. Speak to your healthcare
professional about ways to guard against sexually transmitted
diseases.

serve as a male form of birth control
Cialis is only for men with ED. Cialis is not for
women or children. Cialis must be used only under a healthcare
