A member asked:

Will taking an antihistamine w/decongestant before sinus ct give false results?

A doctor has provided 1 answer

No: Decongestants reduce the swelling in the nose, but do not clear out the sinuses to the point of changing ct results. Other pathologies will be completely unaffected.
