    Expert second opinion

    Many people who have been told they are allergic to a certain medication may not actually be allergic to it. They may have had a one-time reaction, may have been allergic to an ingredient that is no longer used in that drug or may have outgrown the allergy. An inaccurate drug allergy diagnosis can create problems with your medical care. Our experts diagnose whether you have a true drug allergy and, if so, what to do about it.
