You took 2 Tylenol can you take 4 advil?

Follow the directions on the bottle. If in doubt, talk to your doctor. Tylenol is acetaminophen and can cause liver damage if you combine it with other acetaminophen products (and exceed daily recommended limits). This includes cough syrup,etc. Read all labels carefully. yes, there aren't any interactions. both are pain relievers but they work in different ways.
