A member asked:
Can having hypothroidism or taking zyrtec (cetirizine) daily compromise my immune system?
A doctor has provided 1 answer
Yes and No: Not a lot. No. Zyrtec (cetirizine) can help the symptoms of a overreactive part of the system that we call allergy but does not influence the immune system. Hypothyroidism can in more severe cases realted to influences on other structures in the body.
