Side Effects of Impotence Drugs Viagra, Cialis & Levitra

KNOW SIDE EFFECTS TO AVOID COMPLICATIONS

Like all prescription medications, impotence drugs may produce some side effects. These side effects are generally mild to moderate in nature, and usually go away within a few hours of use.

Side effects that may occur while taking sexual enhancements may vary from one drug to another and include headache, flushing, upset stomach, stuffy nose, diarrhea, blurred vision, changes in blue or green vision, or increased light sensitivity, back pain, and or muscle aches.

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.

NAION also happens in men who do not take impotence medicines. People who have a higher chance for NAION include those who:

have heart disease
over 50 years old
have diabetes
have high blood pressure
have high cholesterol
smoke
have certain eye problems
