Is there interaction between Zyrtec and advil cold and sinus?

I'm not a doctor, but in my experience it is safe as long as it is not Claritin D. Claritin is loratadine and Advil Cold & Sinus is ibuprofen and Pseudoephedrin. Claritin D is both of these combined minus the ibuprofen, so I would say it is safe, it has never caused me any problems.
