How Do I Know That I Won't Be Allergic To Another Drug Prescribed By My Doctor?

Question: How do I know that I won't be allergic to another drug prescribed by my doctor?

Katharine Woessner, M.D., Scripps Clinic

Answer: In order to have an allergic reaction to a medication, your body has to have seen that drug on a prior exposure. Therefore, if you've had trouble with medications in the past, a very candid discussion with your physician can help determine an alternative medication that would not put you at risk of having a future allergic reaction.
