Twinkletoes

Zyrtek only worked for a very short time period for me. And at times during
the really bad allergy seasons like now I have to take both.

Zyrtek and Singular. I take singular year round of course its a prescription drug. And I take zyrtek when I can tell I need a second medicine per my allergist and asthma doctor. What I do is take one in the morning and one
at night.

Now before I started taking Singular I took Claritin and now its over the counter also. So you might try calling your doctor and see what they want to do.
