erectile dysfunction
"1st use.  Worked well to achieve and maintain erection.  I'm one of the folks that got significant side effects with 10mg, and am on lisinopril for blood pressure. 12 hours after taking Levitra and blood pressure meds, my blood pressure went up, mild headache throughout the day became severe, and significant stomach flu symptoms.  After about 4 hours, symptoms subsided.  Woke up next morning feeling like day after the flu. Dr. advised taking half BP medicine in the morning, half in the afternoon, with Levitra somewhere in between.  The BP medicine wearing off combined with residual Levitra likely cause of symptoms. Think next time will try 5mg."
