Medicine is used to treat some food allergies.
For mild allergic reactions, people often try nonprescription medicines first. You can try prescription medicines if over-the-counter medicines fail to control allergy symptoms or if they cause drowsiness or other bothersome side effects.
Medicines used to treat a severe allergic reaction include:
- Epinephrine. Epinephrine is given as a shot. It acts quickly to relax the muscles that help you breathe. Sometimes more than one shot is needed if symptoms do not go away. Epinephrine is the medicine used to treat anaphylaxis.
- Antihistamines. Antihistamines block the action of histamine during an allergic reaction and help improve symptoms such as itching and sneezing.
- Corticosteroids. These medicines help reduce inflammation.
Medicines used to relieve mild food allergy symptoms include:
- Antihistamines and corticosteroids for hives, gastrointestinal symptoms, or sneezing and a runny nose.
- Bronchodilators for asthma symptoms. Bronchodilators relax the airways of the lungs, making it easier to breathe.
