A member asked:

Do antihistamines and decongestants cancel each other out if taken at the same time?

2 doctors weighed in across 2 answers
Dr. John Chiu answered

No: Since antihistamine does not provide decongestion (although it does reduce itching, runny nose, and sneezing), it is often combined with a decongestant. Overall ,nasal steroid works much better than these pills.
