Having been on narcotics for the last several years, I have developed the side effect of severe
itching after being on them for a while. This has happened with Demerol, Diluidid,Darvocet,Hydrocodone and Tramadol. I can take Tylenol #3 and morphine (post op in the hospital) with out any problems. Sometimes,if I take one of the itchy ones with Atarax and benadryl I'm ok for awhile, and then the itching will eventually get too bad and I will have to switch to something else.
