is it safe to take more then 10 mg of zyrtec
show more I take Zyrtec every day for my allergies. It says not to take more than one 10 mg pill in 24 hours but my allergies are truly awful. It's not a prescription medication, so I doubt it would hurt me if I took two. It might just make me a bit sleepy.Btw I'm not a druggie.how more I take Zyrtec every day for my allergies.
