Allergy Tests & Allergy Treatments at University of Colorado Hospital

Skin Testing for Allergies

Skin testing is often performed to diagnose allergies. A doctor will determine if skin testing is necessary after reviewing your medical history and symptoms. Tests are performed by pricking or scratching tiny drops of allergen into your skin.

Allergy & Immunology Treatments

Antihistamines

Available in the form of a:

• Pill
• Nasal spray
• Eye drop

Antihistamines block the action of histamine, a chemical released during an allergic reaction that causes inflammation.

Decongestants

Pills, liquids and nasal sprays that relieve nasal and eye congestion caused by allergies.

Corticosteroids

Prescription drugs available as a pill, a nasal spray or eye drop that are used to treat severe allergies. Some corticosteroids have side effects and may not be prescribed for long periods of time.

Allergy shots

Shots may be prescribed to individuals who have allergies. Shots contain small amounts of allergens that are given repeatedly so your body gets used to them and over time stops overreacting to them. Shots may be administered for a couple of months or for longer periods of time, depending on the individual.
