Rare Levitra Side Effects
During clinical studies, there were a number of other side effects that occurred in fewer than 2 percent of people who were taking
Levitra. It is difficult to tell whether these side effects are from Levitra or something else.
Some of these rare side effects include but are not limited to:
In rare cases, people taking medicine (such as Levitra) for
erectile dysfunction have also experienced serious problems that occur in the heart, brain, or blood vessels. These problems include:
Because most of these people had heart or blood vessel (cardiovascular) risk factors, and because the side effects occurred during or shortly after sexual activity, it is difficult to tell the origin of these side effects. Researchers don't know if the problems were related to the Levitra, the person's existing risk factors, sexual activity, or a combination of these factors.
There have also been rare cases of a condition called non-arteritic anterior ischemic optic neuropathy (NAION) associated with the use of PDE5 inhibitors. This condition can lead to sudden loss of vision in one or both eyes
(see Levitra and Blindness).
