Often the pain medication that I have prescribed contains Tylenol (Acetaminophen). If so, you should not take any OTC Acetaminophen products. Too much Acetaminophen can be harmful to your liver.
If you had a rotator cuff repair, fracture surgery, any surgery using bone graft or if I advised against it preoperatively, you should not use anti-inflammatory medications (Motrin, Advil, Aleve, Naprosyn, Ibuprophen, etc.) until I say it is OK. This will usually be around 6 weeks postop.
