Your doctor will ask questions about the medicines you are or have recently been taking, your past health, and your symptoms. This is important for finding out whether you have a drug allergy and finding which medicine is causing the allergic reaction.

Your doctor will ask about:

• All medicines you have recently taken, including over-the-counter medicines. How much did you take and for how long?
• The type of allergic reaction you had. If you had a skin rash, what did it look like? What other symptoms did you have?
• When the allergic reaction happened.
• How long it took for the reaction to stop.
• Current or recent viral infections, such as having a cold or the flu.
• A previous reaction to a medicine.
• A family history of drug allergies or other harmful (adverse) drug reactions, such as side effects.
• Any long-lasting diseases you may have, such as asthma or diabetes.
