There are some steps that we encourage all clients to follow to ensure we are able to get the most accurate results. First, you will need to be sure your pet has not had certain medications just prior to the test. Ideal withdrawal periods (with some exceptions – please call for more patient-specific questions) for an intradermal allergy test are:

• 4 weeks off injectable steroids (some injectable forms take longer)
• 1 – 2 weeks off oral steroids
• 1 – 2 weeks off a topical ear, eye, and skin medications, creams, sprays, and shampoos with steroids
• 1 – 2 weeks off antihistamines (including Histacalm shampoo/spray and Resihist). Some behavior modification medications are antihistamines such as Clomicalm, Doxepin, and Elavil (AKA amitriptyline)

You may bathe your pet up to the day of testing if the shampoo does not contain any steroids or antihistamines. You may also use topical flea products such as Advantage, Frontline Topspot, or Revolution prior to the testing. If you are unsure if your pet’s medications need to be stopped prior to testing, please call our office.

Typically, the test is scheduled in the early afternoon. Your pet will be sedated for his or her comfort, so we ask that you do not feed your pet the morning of the test.
