Generic Levitra (Vardenafil 20mg) is an oral prescription medication used to treat erection problems in men. Levitra is usually taken 30 to 60 minutes before sexual activity. Its effects sustain for about 4 hours of action. Levitra is considered as a good competitor to replace Viagra and Cialis and is gaining more popularity day by day.
Vardenafil belongs to the class of medications called phosphodiesterase type 5 inhibitors. Most men find Vardenafil works the very first time they use it. It works for men who have occasional ED and for men who need more frequent help. Afterwards, the blood flow decreases and the erection goes away.
Vardenafil should be taken orally along with water and should be taken 30 - 60 minutes before having sexual intercourse. Levitra should be taken only as directed, usually once daily as needed. Do not change the dose of your medication. Please call your doctor to determine if your dose needs to be reevaluated. Because alcohol can make it more difficult to get an erection, do not drink large amounts of alcohol before sexual activity.
Contact your physician immediately if the erection lasts longer than 4 hours or if it becomes painful. If you have had a stroke or kidney problems that require dialysis, a bleeding problem; a deformed penis shape, blood pressure or high blood pressure that is not controlled, blood cell problems such as sickle cell anemia, multiple myeloma or leukemia, avoid taking Levitra without telling your doctor first.
The most common side effects include headache, upset stomach, stuffy nose, visual changes such as mild and temporary changes in colors or increased sensitivity to light, and diarrhea. Side effects that you should report to your prescriber or health care professional as soon as possible: changes in hearing such as loss of hearing or ringing in ears, eyes being more sensitive to light, chest pain or palpitations, difficulty breathing, shortness of breath, eyelid swelling, muscle aches, prolonged erection (lasting longer than 4 hours), itching.
