I was diagnosed with an antibiotic allergies at a young age. Recent testing failed to prove if I'm really allergic. Can an oral challenge test help?
Drug allergy: Most of the time there is no true allergy to a certain drug, rather an adverse drug reaction interpreted as an allergy, yet we cannot speculate. I'm not sure what kind of allergy testing you had that failed, and why do you want to go for an oral challenge if there is a safer antibiotic alternative that you aren't allergic to. If necessary, consult an allergist, check aaaai. Org for one in your area ...Read more
Immune activation: The body recognizes foreign substances as invaders at time and will immunologically react against them.

Will an antibiotic allergy go away on its own? I got hives from Hydrochlorothiazide on my face & chest. I've been using Benadryl (diphenhydramine) & water gels for pain
Yes: But the time it takes for remission to occur (if it goes away at all) depends on the medication. People with sulfa allergy almost never loses the allergy but those with penicillin allergy tend to lose it in 5-6 years. Do note that hydrochlorothiazide is not a common allergen and you should consider seeing an allergist to document this allergy. Benadryl (diphenhydramine) gel for pain? Does it work? ...Read more

Every time I have had an antibiotic I have had an allergic reaction. I have a had inconclusive allergy testing. What antibiotics can I use if needed?
Not sure: Many types of adverse reaction occur with antibiotics. Worrisome reactions occur after your body produces antibody against a drug (requiring prior exposure) or severe delayed reactions that may involve rash, liver damage, joint destruction etc. Most adverse reactions are not immune-mediated. Its very abnormal to have true allergy to many antibiotics. See an allergist willing to provide answers ...Read more
