Can you take Levocetirizine with Zyrtec?

In my case, the answer is yes. I have Asthma, and seasonal Allergies. I have been on claritin for years, but this year i have had significant nasal allergies that the claritin hasn't prevented, such as post nasal drip, which then causes congestion and asthma flare ups. So my Pulmonologist just prescribed Atepro nasal spray to be taken daily along with claritin.
