Vardenafil treats erectile dysfunction. It relaxes muscles of blood vessels, increasing blood flow to particular areas of the body. This drug is not approved for use in women or patients under 18.

Do not use Staxyn in place of Levitra. Take with/without food. This medicine is taken as-needed, around an hour before sexual activity. This medicine cannot cause an erection just by taking it. If you receive care for heart issues, tell medical personnel the last time you took vardenafil.

Inform your doctor of your medical history, especially if you’ve had heart problems, eye disorders, seizures, long QT syndrome (or a family history of), or phenylketonuria. Inform your doctor of other medications you take, especially riociguat, other ED medications, heart rhythm medicine, and hypertension or prostate disorder medicine. Do not take vardenafil if you also take a nitrate drug for heart issues, including recreational “poppers.” Avoid grapefruit products. Alcohol may amplify side effects.

Get medical attention at once if your erection is painful or lasts longer than 4 hours, or if you have sudden vision loss. Get emergency medical help if you experience serious side effects, such as: allergic reaction, heart attack symptoms, vision changes, prolonged erection longer than 4 hours, hearing problems, irregular pulse, swelling in hands/ankles/feet, shortness of breath, lightheadedness, seizure. Other side effects include flushing, stuffy nose, sinus pain, upset stomach, back pain, and headache.
