Show Cold, cough, and flu season is a good time to revisit the risks of acetaminophen—the pain and fever reliever in Tylenol and many other over-the-counter medications. Billions of doses of acetaminophen are consumed safely every year, but deaths still occur from accidental overdoses and thousands of people end up in the emergency room. More than 600 products contain acetaminophen, and inadvertently combining them can nudge you into the red zone. "People don't realize that these doses all add up, and before you know it you've exceeded the recommended dose of acetaminophen," says Dr. Melisa Lai Becker, instructor in medicine at Harvard Medical School and a specialist in emergency medicine and toxicology at Harvard-affiliated Cambridge Health Alliance. Acetaminophen safe dosage basicsAcetaminophen controls pain and fever but does not reduce inflammation, as does aspirin and the other widely consumed nonsteroidal anti-inflammatory drugs (NSAIDs) ibuprofen (Advil, Motrin, generics) and naproxen (Aleve, generics). But unlike NSAIDs, acetaminophen does not irritate the stomach and intestinal lining. That means a person who cannot tolerate NSAIDs can still take acetaminophen. It's an important drug for controlling chronic pain in older adults. The hitch is that acetaminophen also has a narrower window of safety compared with ibuprofen and naproxen. NSAIDs can make you sick, too, but it takes a larger amount to reach a dangerous overdose. Taking too much acetaminophen can damage the liver, sometimes leading to a liver transplant or death. The body breaks down most of the acetaminophen in a normal dose and eliminates it in the urine. But some of the drug is converted into a byproduct that is toxic to the liver. If you take too much—all at once or over a period of days—more toxin can build up than the body can handle. For the average healthy adult, the generally recommended maximum daily dose is no more than 4,000 milligrams (mg) from all sources. But in some people, doses close to the 4,000 mg daily limit for adults could still be toxic to the liver. It's safest to take only what you need, and to not exceed 3,000 mg a day whenever possible, especially if you use acetaminophen often. How to stay within limitsIf you ever have concerns about how much acetaminophen you can tolerate based on your age, body size, and health status, talk to your doctor or pharmacist. Here are some general precautions for avoiding an accidental overdose of acetaminophen.
How much should you worry?Tens of thousands of people become ill every year from taking too much acetaminophen. In a smaller number of cases—several hundred per year—it leads to death. But it need not happen to you. "Read the labels and stick to the guidelines," Dr. Lai Becker advises.
The maximum daily dose for a healthy adult who weighs at least 150 pounds is 4,000 milligrams (mg). However, in some people, taking the maximum daily dose for extended periods can seriously damage the liver. It's best to take the lowest dose necessary and stay closer to 3,000 mg per day as your maximum dose. If you need to take high doses of acetaminophen for chronic pain, check with your doctor first.

Is Extra Strength Tylenol the same as acetaminophen?1 The difference in Tylenol products has to do with the amount of acetaminophen in each tablet, capsule, or gelcap. This is measured in milligrams (mg). Each regular strength Tylenol contains 325 mg acetaminophen. Each Extra Strength Tylenol contains 500 mg acetaminophen.
What is the highest milligram in Tylenol?In acetaminophen products available over the counter, each pill may contain 325, 500, or 650 milligrams of the drug.
How many Tylenol can I take extra strength?To help encourage the safe use of acetaminophen, the makers of TYLENOL® in 2011 lowered the maximum daily dose for single-ingredient Extra Strength TYLENOL® (acetaminophen) products sold in the U.S. from 8 pills per day (4,000 mg) to 6 pills per day (3,000 mg).
