I went in this morning to get the injection of Alprostadil which I think is Caverjet. Since this was my first try the nurse only gave me a .10 mg dose. The nurse showed me how to do the injection and it was not a problem with no pain and went very easy. I left the doctors office and had a drive home of about 1 1/2 hours. I achieved the start of an erection at the doctors office, but in drive home it increased and continued for over four hours. When I could see it was not going down (even after intercourse) I was ready to go to the emergency room, but on a whim I took an anti inflammatory pill I had and when I called the nurse she told me to try taking a Sudafed. However, within a few minutes of taking the anti inflammatory pill I could feel the pressure lessening substantially. Within 15 minutes it was back to normal and I was very relieved. In case this happens to anyone else I thought you would like to know about my remedy.
