How many lorcet can you take in a day?

Depends on your tolerance. But be careful for the Tylenol in it, which can cause a very long, very slow, very painful death over the course of a few weeks. I take percoset regularly and I have a high tolerance. More then 3, 5/325mg tablets makes me nauseous. You should take no more then 2 every 4 hours and never exceed more then 12 every 24 hours.
