Will I be okay? I took two different medicines both containing Acetaminophen with both having 500 mg of it. Also within an hour apart. This isn't the first time I have done this. I usually only do this on my period because of how bad my cramps are. I'm only 95 pounds and within the age of 14-17.
This is an excellent question to ask any pharmacist and you will get a good answer.
And here's a good overview of acetaminophen toxicity:
The dosage for an adult is 4000 mg per day maximum.
Taking 1000 mg ( or perhaps 2000 mg ) for someone of your mass should not be toxic. Unless you are allergic to acetaminophen. The problem with too much of this medication is the liver flushing time and amount taken.
