The following meds have caused mild hives: benadryl, nsaids, tylenol, (acetaminophen) mestinon, morphine, vicodin. Could this be something other than allergy?
Yes. Opiates are known to be able to induce or aggravate hives for some people. Nsaid allergy is usually specific for that one and not to all others. Tylenol (acetaminophen) and Benadryl allergies are rare if ever present. Since you have chronic urticaria, i suspect that many of the reactions you have described might have been incidental and not related. You need to consult an allergist.
Unlikely. If you have problem with Opiates (more likely intolerances than allergies), you are more likely to have problem with Dilaudid as well. However there may be exceptions , perhaps starting at a 1/4 of the dose then gradually work the dose up may be helpful if Dilaudid is a drug you really needed. Read more...
