Levitra (vardenafil) is intended for men with impotence caused by a wide array of physiological and psychological factors. There are a number of medical conditions that need to be reported to your health care provider, including kidney or liver disease, heart disease, a history of a stroke, heart attack, retinitis pigmentosa, high or low blood pressure, bleeding disorder, leukemia, stomach ulcer or sickle cell anemia. Some of these conditions may require a dose adjustment while others can actually prevent you from taking this medicine. When taking Levitra you can experience mild or more serious side effects. The mild side effects such as stuffy nose, headache, warmth or redness in your neck and face, memory problems, back pain and an upset stomach are most likely to go away and do not need to be reported to your health care provider unless they interfere with your everyday activities.
More serious side effects can include priapism (a painful and prolonged erection lasting over 4 hours), blurred vision, shortness of breath, fainting, lightheadedness, irregular heartbeat, chest pain, sudden hearing loss, ringing in your ears, nausea, sweating, swelling in your ankles, hands or feet. If you are also using any nitrate-based drugs you must not take Levitra as it can cause a sudden drop in blood pressure and result in a stroke or a heart attack. Other medicines that should not be taken simultaneously with Levitra include antidepressants, antibiotics, high blood pressure medications, as well as diclofenac, enoxacin, imatinib, isoniazid and conivaptan. Make sure you talk to your doctor before starting to take any other drugs along with Levitra to avoid drug interactions. If you are not sure about whether Levitra will interfere with the medicine you are taking consult your doctor or pharmacist.
