The most common side effects with vardenafil hydrochloride tablets are headache, flushing, stuffy or runny nose, indigestion, upset stomach, dizziness or back pain. These side effects usually go away after a few hours. Call your doctor if you get a side effect that bothers you or one that will not go away.
Vardenafil hydrochloride tablets may uncommonly cause:
An erection that won't go away (priapism).If you get an erection that lasts more than 4 hours, get medical help right away. Priapism must be treated as soon as possible or lasting damage can happen to your penis including the inability to have erections.
Color vision changes,such as seeing a blue tinge to objects or having difficulty telling the difference between the colors blue and green.
In rare instances, men taking PDE5 inhibitors (oral erectile dysfunction medicines, including vardenafil hydrochloride tablets) reported a sudden decrease or loss of vision in one or both eyes. It is uncertain whether PDE5 inhibitors directly cause the vision loss. If you experience sudden decrease or loss of vision, stop taking PDE5 inhibitors, including vardenafil hydrochloride tablets, and call a doctor right away.
Sudden loss or decrease in hearing, sometimes with ringing in the ears and dizziness, has been rarely reported in people taking PDE5 inhibitors, including vardenafil hydrochloride tablets. It is not possible to determine whether these events are related directly to the PDE5 inhibitors, to otherdiseases or medications, to other factors, or to a combination of factors. If you experience these symptoms, stop taking vardenafil hydrochloride tablets and contact a doctor right away.
These are not all the side effects of vardenafil hydrochloride tablets. For more information, ask your doctor or pharmacist.
