Question: I have been taking 5 mg of Cialis daily for more than a year, but recently ran out of the medicine and have been four days without the Tadalafil. I haven't noticed any change in urinary symptoms. I am wondering whether I should ask my urologist about changing my prescription to 50 mg of Viagra to be used when I intend to have sex and to stop taking the 5 mg Cialis. I began taking Cialis 5 mg because my erections weren't as strong as I would like, but, even with Cialis taken daily, my erections are not quite as firm as I would like, though I have not lost function. Also, I began a regimen of testosterone shots (270 mg every 21 days) which has increased my testosterone level from 240 to 636. That has given me increased strength and libido but hasn't done anything for the firmness of my erections--I didn't expect it to do so. I have gained a little weight (15 lbs.) but my pants fit looser, so I am losing some belly fat and increasing muscle. I wonder if the testosterone injections have decreased the need for the Cialis 5 mg? Since this is the new year, my insurance company requires my urologist to ask for approval for the Cialis 5 mg, so I won't be getting anymore of those pills for at least three more days, anyway. This might be a good time to ask him about changing the prescription from Cialis to Viagra. What do you think?
