Like Tylenol, Anacin, tramadol, meloxicam?
You really need to ask your surgeon what you can and can't take prior to surgery because it may make a difference depending on the type of surgery, anesthesia, etc.
I know aspirin products (like Anacin) and medicines containing ibuprofen need to be stopped (usually at least a week or more prior to surgery) because they tend to thin your blood, which could cause significant bleeding problems during surgery. I'm not sure about meloxicam.
I recently had two different surgeries and both times I was allowed to continue taking tramadol – even the morning of the surgery. And I think Tylenol is ok. But as I mentioned before, you really need to ask your doctor. And it's extremely important on the day of surgery that you tell the doctors exactly what medications you took and when you last took them.
