Treatment for acetaminophen overdose
depends on how much time has passed since the overdose and whether the overdose happened all at one time or over a longer period of time. You may be given activated charcoal medicine to soak up the APAP that is still in your stomach. Activated charcoal will make you vomit. Gastric lavage may be needed to clean out your stomach to get rid of the APAP. Gastric lavage is also called having your stomach pumped. You may be given antidote medicine to stop the effect of the overdose. You may also be given medicine to slow down the effects of APAP.
Prevent acetaminophen overdose:
- Read labels carefully. Read the labels of the medicines that you take. If your medicine contains APAP, it will be listed in the active ingredients section. Check carefully to see if the APAP is a regular or extended-release form. Ask your healthcare provider if you are not sure what is in your medicine.
- Take the correct dose. Make sure you take the right amount and wait the right number of hours between doses. Never take more than the label says to take. Do not take APAP for more days than directed. If the medicine came with a special device such as a spoon or dropper, use that device to measure your medicine.
- Do not take acetaminophen for too many days in a row. Do not take APAP for more than 10 days to treat pain, unless your healthcare provider tells you to. Do not take APAP for more than 3 days to treat a fever, unless your healthcare provider tells you to. Your pain or fever may need to be treated another way if it lasts more than a few days.
- Do not take more than 1 type of acetaminophen at a time. Many combination medicines contain APAP. Make sure the total dose of APAP you take is not more than 4,000 milligrams (4 grams) in 1 day. Ask your healthcare provider if you are not sure how much you are taking.
Follow up with your healthcare provider as directed:
Write down your questions so you remember to ask them during your visits.
