It will be one of the anti-inflammatories..ie Motrin (Ibuprofen), Aleve, and the like......Tylenol doesn't have anti-inflammatory properties.
You need to read label and take as directed.There has been some warnings about not to take this class of medicine if you have heart disease,or have had heart attacks...also if you have an history of ulcers you should avoid this class of medicine.
Taking too much Tylenol can be bad for your liver though...so if you have doubts check with your provider.
