Is it safe to take zyrtec (cetirizine) and loratadine (claritin) at the same time?

Zyrtec (cetirizine) loratidine: Yes but can get expensive and i wouldn't recommend it routinely.

Yes: Yes, but i would only recommend it for conditions like urticaria (hives) and angioedema. If you are treating nasal symptoms with this combination, i would rather use only one and add other types of medications like nasal steroid sprays, singulair, (montelukast) etc.
