Patient Information Sheet
Sildenafil citrate (marketed as Viagra)
This is a summary of the most important information about Viagra. For details, talk to your healthcare professional.
FDA ALERT [07/2005]: A small number of men have lost eyesight in one eye some time after taking Viagra, Cialis, 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 Viagra, Cialis, 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:
have heart disease
are over 50 years old
have diabetes
have high blood pressure
have high cholesterol
smoke
have certain eye problems
FDA has approved new labels for Viagra, Cialis, and Levitra to include information on possible eyesight loss (NAION).
Stop using Viagra, Cialis, 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 Viagra?
Viagra 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. Viagra may help a man with ED get and keep an erection when he is sexually excited. Viagra must be used only under a doctor’s care.
Viagra 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
Viagra is only for men with ED. Viagra is not for women or children. Viagra must be used only under a healthcare professional’s care.

Do not take Viagra if you:
take any medicines called “nitrates”

What are The Risks?
The following are the major possible risks and side effects of Viagra therapy. This list is not complete.
Viagra can cause your blood pressure to drop suddenly to an unsafe level if it is taken with certain other medicines such as nitrates and alpha-blockers, and recreational drugs that contain nitrates called “poppers.” A sudden drop in your blood pressure could cause you to become dizzy, faint, or have a heart attack or stroke.
Tell all your healthcare professionals that you take Viagra. If you need emergency medical care for a heart problem, it will be important for your healthcare professionals to know when you last took Viagra.

an erection that won’t go away (priapism)
vision changes, such as seeing a blue tinge to objects or having difficulty telling the difference between the colors blue and green
