Just to be safe I would do OTC tylenol like pepper said, or if you have anything like vicodin. Definitely no aspirin, aleve, or any blood thinning pain reliever, and my doc said not ibuprofen either. And you definitely don't want to take any ibuprofen after the surgery for at least the first few weeks. Stick with tylenol.
Here is a pretty complete list of NSAIDS (Non-Steroidal Anti-Inflammatory Drugs). These need to be discontinued for several weeks before surgery, and held for months after a fusion to allow new bone growth.
SpineAz is correct that too much acetaminophen is dangerous to your liver. People have died from completely accidental acetaminophen overdoses. Generally we say 4000 mg (8 extra strength Tylenol) is the 24 hour limit for most people. Anyone who consumes alcohol daily or has any type of liver disease is not even allowed that much.

Yep, Tylenol would be the treatment of choice. It never did squat for me, though, unless it was just along for the ride with something stronger, like Vicodin or Percocet. If you're like me and it doesn't do anything, you might have to give your doctor a call and ask if there's anything else you can take.
