A member asked:

Is it ok to take promethazine w/codiene for a cough during allergy patch testing? what other meds should i avoid?

A doctor has provided 1 answer
Dr. John Chiu answered

Contact allergen: If you are looking for contact allergens on a skin condition, this medication would not affect the test at all. But if you are looking for airborne allergens causing hay fever, asthma etc, then a 72-hr elimination period is needed.
