Can you give Tylenol and Claritin together?

Yes you can. Just don't exceed too much acetaminophen(Tylenol) in 24 hours. Maybe like, 3000mgs would be lethal. Acetaminophen can damage your liver and lead to some serious issues if you take it irresponsibly. Claritin doesn't really have any negative side effects, but I would recommend taking the recommended dosage on the back. :D Same goes with the Tylenol.
