benign prostatic hyperplasia
"My urologist suggested that I try 5 mg. Cialis daily for BPH (enlarged prostate). He gave me a two week supply to see if I would incur any side effects. He did make it very clear that treatment for BPH requires about a month's regular use of the 5 mg. daily dose. From the first day onward, I experienced significant heartburn, which was easily remedied by taking a dose of Zantac with the Cialis and a Zantac, 12 hours later. On the 5th day of Cialis, I experienced excruciating muscle pain starting with my lower back, into the buttocks, and legs. At the ER I was informed that between 5-7% of Cialis users will experience this and to stop using Cialis immediately."
