Is 2275mg of acetaminophen enough to overdose? a friend of mine texted me about taking 7 5/325 percocet and i'm scared for him.

Generally not: but depends on whether it was combined with alcohol or not. The toxic dose of acetaminophen is usually in the range of 7000-10,000 mg, but almost any amount of alcohol can cause smaller amounts to be toxic. If your friend values your opinion, and understands that you are concerned about him, see if you can get him to see a counselor regarding his drug use BEFORE there is a worse problem.
