Levitra (vardenafil) can be recommended for patients unable to achieve a stable erection. Its effects are based on the active ingredient expanding the blood vessels in the penis contributing to a greater blood inflow and preventing the blood from going back into the body. Levitra works for most patients helping them to achieve a stable erection that lasts long enough to have sex. Levitra becomes effective within one hour and the patient can have sex during the next 4 hours. The medicine starts to be effective when some sexual stimulation is provided, although the patient is likely to get excited after less stimulation than usually needed.
Side effects reported by patients taking this medicine include indigestion, facial flushing, headache, nasal congestion, upset stomach, and flu-like symptoms. These side effects are not likely to last long and go away without any treatment required. People with heart disease risk factors (high cholesterol, diabetes, smoking, age, obesity and high blood pressure) or cardiovascular disease are more likely to experience serious side effects of this medicine. The problems can occur with your brain, heart and blood vessels causing a stroke, sudden death and heart attack.
