Is it safe to take tylenol while taking valacyclovir

What do you have, shingles or herpes ? This med is used for these and others. Ask your doctor if you can take tylenol..

Yes, it is safe to take tylenol with Valtrex.

I will only add, since J9 gave you a great answer.

The medication comes with a fact sheet, and normally talks about drug interaction.
Also, the druggist you get the medication from, is available to ask, questions on the medication you take.
