Medicine colchicine

Hi my son takes colchicine daily. I would like to know if that’s kosher for Passover.

In addition I take xyzal each day due to allergies and wanted to know if that’s kosher for Passover.

Thanks

Hi, is the colchicine a swallow pill?
If so it is fine.
Xyzal is approved

Is NyQuil pills cough and cold ok for Pesach?
