I have high blood pressure and take meds for it. Should I take Zyrtec?

Which high blood pressure medicine(s) are you taking? Generally it is fine to take Zyrtec with high blood pressure medicines.

yes, antihistamine such as zyrtec has no known side effects for most people even with high blood pressure. Although it may cause sleepiness for some, just avoid activities that will require motor skills like driving or operating heavy machine. Take it in the evening after supper.
