I had to switch to using xyzal last year. Zyrtec just wasn't cutting it anymore. All I could find the stores was the name brand and it is not cheap. Well, we ran out and I sent dh to the store. He texts me and asks if the generic is ok. I was like, what generic? I actually didn't trust he was looking at the right medicine. He comes home and low and behold there is now a generic xyzal! Yipee! and it works!
