What is the context: Depends on what you are looking for. No simple test. There are specific tests for certain things (penicillin). There are a few tests done to determine if an individual can tolerate a certain med (G6PD). Mostly, though, it comes down to trial of a med and knowledge of what to look for. For example if you get a cough with ACE inhib (lisinopril) your DR will change you to ARB (valsartan) ...Read more

My mom said I was allergic to sulfa drugs as a child, so could I have outgrown this allergy 20 years later?

It may not be worth your effort, since so many other new meds are available to treat you when needed ...Read moreSee 1 more doctor answer

Been on Hydroxyzine for a month now with AMAZING results on both anxiety and allergies, is it safe to use this drug long term?
Yes, but: Hydroxyzine has very little usefulness for Anxiety in the long term. It is primarily an allergy medicine.

Does cause numbness if held in mouth too long (topical anesthetic). Hope that helps. Bug the one who prescribed it for you. Pharmacist who filled it also a good resource, especially if at an independent pharmacy (my choice!) ...Read moreSee 1 more doctor answer
