Acetaminophen is the most commonly used medicine in the United States, and is found in both over-the-counter (OTC) and prescription medications. It is used for the temporary relief of minor aches and pains and fever.
When used as directed, acetaminophen is very safe and effective. When too much is taken or for too long, it can cause health risks. Taking too much acetaminophen may mean overdosing on it, which can cause liver injury.
Here’s what you need to know about acetaminophen and how to use it safely:
- Always read and follow the Drug Facts label before taking any OTC medicines. The directions on the label will tell you how much acetaminophen you should take and for how long.
- Do not take more than what the label says. Taking too much acetaminophen may lead to an overdose and liver injury.
- Because acetaminophen is found in many OTC and prescription medicines, it is important to always read the active ingredients section on the OTC label before taking any medicine. Taking two medicines that both contain acetaminophen, OTC or prescription, may put you at risk of an overdose and may increase the risk of liver injury.
- If you are not sure whether your medicine contains acetaminophen, ask your pharmacist or other healthcare provider to make sure you are not taking more than one product with acetaminophen at the same time. Remember, while acetaminophen may be written as “APAP” on prescription drugs, it is the same ingredient.
- Don’t take acetaminophen-containing medicines if you drink three or more alcoholic drinks a day, as this may cause severe liver injury.
- Always keep all medicines out of reach and sight of children.
If you have any questions about acetaminophen or using it safely, talk to a healthcare professional.
