Levitra.

Levitra (vardenafil) is supposed to be taken by males that experience problems with getting and maintaining an erection that would be hard enough to have sex. You will need to tell your health care provider about any medical conditions you have that may affect the success of your treatment – such as chest pain, a recent history of a heart attack, blood cell disorder, congestive heart failure, bleeding disorder, high or low blood pressure, stomach ulcer, a history of stroke or blood clots, retinitis pigmentosa, liver disease, physical deformity of the penis, kidney disease, or heart disease. Your doctor will need to know if you are taking any nitrate drugs or other medications that can cause interactions. Make sure you report antidepressants, antibiotics, diclofenac, imatinib, heart rhythm medicines, drugs to treat high blood pressure, heart or blood pressure medications, HIV/AIDS medicines, antifungal medications, conivaptan, or isoniazid. Heartburn, upset stomach, flu-like symptoms, headache, stuffy or runny nose, or flushing are considered to be mild side effects, while seizure, sudden vision loss, swelling in your hands, ankles, or feet, pain spreading to the arm or shoulder, vision changes, irregular heartbeat, shortness of breath and ringing in your ears must be reported to your doctor.
