A member asked:

Is it possible to develop an allergic reaction to a drug/antibiotic that you've never had an allergic reaction to in the past?

Dr. Mahmoud Moammar answered

Specializes in Pulmonology

Yes...: Developing allergic reactions to some medications esp. Antibiotics would require prior exposure to the medicine. The allergies could be idiosyncratic meaning that it is time and dose independent.
