I have been taking zyrtec and axid twice a day along with singulair, allegra and hydroxidine for four months now. My pharmasist told me today that I shouldn't take all these antihistamines together. It can cause my tongue to swell, which is why I am on all these meds to begin with.





There was a Pharmacist agreed for me to take Zyrtec and Singulair together at the same time. I already took those 2 tablet a while ago, hope nothing will happen to me tonight.
