I had them about 7 years ago, they lasted about a year. I'm taking Zyrtec
(once a day), Zantac (2 / day), Doxepin (150 mg @ bedtime), and Benadryl
as needed. I had been on prednisone on and off since July but my doctor has taken me off of it (for obvious reasons). Unfortunately nothing I've taken other than prednisone has worked. My hives are particularly associated with pressure (underwear) - Since September i have worn a tank top under my clothes due to hives associated with wearing a bra.
