I think you can take up to 4 grams a day but, too much Tylenol daily is not good for your kidneys. So if your taking a lot of Lortab for pain on a daily basis, you might want to try narco. That has less Tylenol or even a long acting painkiller if it's for daily pain.

Since it doesn't sound like you have a lot of migraines, I wouldn't worry about the Tylenol in the fioricet.
