Staxyn (vardenafil) Dosage and Side Effects
STAXYN used to treat men who have sexual impotence, also known as erectile dysfunction or ED. It's part of a group of drugs known as phosphodiesterase-5 (PDE5) inhibitors. PDE5 inhibitors work by preventing an enzyme, PDE5, from working too rapidly in certain areas of the body, including the penis.

Warnings and Precautions
In 2007, the FDA issued safety information about STAXYN and other ED medicines, warning of possible sudden hearing loss in some men.
The information was issued after a case report in medical literature that described a man having sudden hearing loss after taking Viagra (sildenafil).
While no direct cause and effect was demonstrated, the FDA said that the link found between the ED drug use and hearing loss in the case report and other reports warranted a change in the label to reflect the potential problem.
If your erection is painful or continues beyond four hours as a result of taking STAXYN, you should contact your doctor right away.
A prolonged erection could cause serious and permanent injury to your penis.
Pregnancy and STAXYN
STAXYN is only for use in men. Women should never take it, especially if they are pregnant or breastfeeding.
