Yep, the narcotic in the Tylenol 3 can be constipating, the tylenol part of it is OK.One thing to do to reduce the amount of pain meds you need is ice your jaw after the surgery. I had an ice pack and a timer and every 15 minutes I switched sides (you usually want to do the ice on and off anyway as ice for too long could cause frostbite)I would continue what you do to control constipation and you might want to consider adding an over the counter stool softener to the mix and take it when you take the narcotics. I'm not normally constipated, but was after a recent surgery with some heavy narcotics and the stool softeners do make a difference for me.I'd at least take the narcotics the first day or so, but you might be able to switch to regular OTC tylenol after that. Good control of the pain early on, at least for me, really does limit the amount of time I am in pain, and also seems to make me heal up faster (I don't have the added stress of the pain slowing things down).If the regular dose of the over-the-counter tylenol isn't enough to control the pain, don't increase the dose of that, go back to the tylenol-3 for your next dose. Over-dosing the tylenol can be really, really bad for the liver. It is not a problem for the liver if you stick to the recommended dose, but don't try to control it with more tylenol at a time. Trading liver failure for constipation isn't a good idea.K.
