Is the Percocet prescribed by the dentist for your pain? If so, then I would follow their instructions. And many times it is better to rotate and not take at the same time the acetaminophen and the ibuprophen as Caryopteris mentions.
So...if the Percocet prescription reads to take one half or one tablet, then you can add in an Advil in 4-6 hours after that.
But if the Percocet was prescribed by another Dr. for another pain issue in the past....then you should not be taking this to self medicate your dental pain.
I would not do that. You would be mixing 3 pain relievers. Percocet has acetominophen (Tylenol). I doubt your liver would enjoy the mix.
I would check with your dentist or pharmacist. If bones are healing, you don't want to take Advil. That's what an orthopedic surgeon once told me.
For some problems, you can alternate your pain meds. If your stomach isn't overly sensitive, you can probably handle 3 Advil at once. Then after 4-5 hours you could take a different pain medicine like Percocet. When 6 hours is up (or whatever the bottle says), then try the 3 Advil again.
Yes, because Advil contains no acetominophen. (Tylenol). However, Percocet DOES contain Tylenol so you cannot take any other tylenol products with the Percocet.
