You may need an allergy test that uses a needle to inject a small amount of allergen extract into the skin on your arm (intradermal test). The injection site is examined after about 15 minutes for signs of an allergic reaction. Your allergist may recommend this test to check for specific allergen such as penicillin.
Allergen immunotherapy, also known as allergy shots, is a form of long-term treatment that decreases symptoms for many people with chronic allergy symptoms. Allergy shots are regular injections over a period of time to stop or reduce allergy attacks. Allergy shots are a form of treatment called immunotherapy with each shot containing a tiny amount of the specific substance or substances that trigger your allergic reactions.
Your allergy treatment plan may include medications, immunotherapy, changes to your work or home environment, or dietary changes. Ask your allergist to explain anything about your diagnosis or treatment that you don’t understand. With test results that identify your allergens and a treatment plan to help you take control, you’ll be able to reduce or eliminate allergy signs and symptoms.
