If you get sick, your health care team may have to act fast. Before they give you any medicine, they need to know if you could have a bad reaction to it. That’s why you should tell them in advance about any allergy or reaction you have ever had to any medicine or food.
Reactions can include rashes, headaches, breathing trouble, and feeling sick. Because some medicines have food in them (such as the eggs used in the flu shot), be sure to talk about your food allergies too. Tell a member of your team right away if a new medicine makes you feel unwell. If you do not know if you have allergies, you can get tested.
Don’t wait until you get sick to tell people about your allergies. Some people wear an ID bracelet such as MedicAlert™. This tells the health care team about your allergies when you can’t tell them yourself.
