That said, don’t throw your bottle of pain relievers in the trash. But make sure you never take more than a total of 4 grams of acetaminophen in a 24-hour period. You should also be aware of any other medication you take that may also contain acetaminophen.
Causes and Statistics
Since the pain reliever is included as an active ingredient in many different over-the-counter (OTC) products, including those for headache relief, cold and flu, and cough, you can take more than you realize pretty easily. Many people think OTC medicine is harmless, and that’s just not true with regards to acetaminophen.
Acetaminophen is the leading cause of acute liver failure in the United States, according to a report published in the British Medical Journal. The same report notes that acetaminophen overdose accounts for 82,000 emergency room visits and 26,000 hospitalizations each year.
Liver failure caused by acetaminophen is usually seen in:
People who are depressedPeople in chronic painPeople who misuse alcohol or narcoticsPeople who take several acetaminophen medications at the same time
Sadly, some people overdose on acetaminophen in an attempt to commit suicide.
Accidental Overdose in Oklahoma
One case of accidental overdose occurred in Oklahoma when 17-year-old Kellie Lynn McWilliams, who was having a migraine attack, took approximately 20 acetaminophen capsules. Each capsule contained 500 milligrams (half a gram) of acetaminophen.
Her dose was equal to ingesting 10 grams of acetaminophen. The maximum recommended within 24 hours is 4 grams. And anything more than 7 grams is considered a severe overdose.
When Kellie became ill, repeatedly vomiting, she was admitted to the hospital. She even told her mother, “I thought it was OK. It’s just Tylenol, Ma.” But the side effects of the overdose caused kidney and liver damage resulting in organ failure. It ultimately led to her death.
How to Avoid Accidental Overdose
When you’re in the middle of experiencing pain from a headache or a migraine, your thinking isn’t always clear. That makes it much easier to accidentally overdose on pain relievers.
It is important to never take more than 4 grams of acetaminophen within 24 hours. That’s equal to 4,000 milligrams (mg), or about eight extra-strength (500 mg) tablets.
If you have a liver condition or drinking problem, even this may be too much. Speak with your healthcare provider to determine the right dose for you.
Here are some do’s and don’ts for avoiding an accidental overdose.
Alternatives to Tylenol
While taking Tylenol for a headache is a reasonable approach, you may want to consider a non-medication therapy first. For instance, if you are sleep-deprived or hungry, taking a nap or eating a nutritious snack may soothe your headache.
If you find that you are taking Tylenol or another medication frequently, it’s good to be aware that you may be at risk for developing a medication overuse headache. This is a rebound headache that forms as a result of taking headache medication too much. Too much acetaminophen may mean you are taking it more than 10 to 15 days per month, depending on the specific drug.
Summary
Tylenol is a brand name of acetaminophen. It helps with pain relief. Many people think that it’s harmless because it’s an over-the-counter drug. But if you take too much of it, you could experience liver or kidney damage. Overdosing on acetaminophen can even lead to death.
To avoid overdose, never take more than 4 grams of Tylenol within 24 hours. But if you have liver disease or a drinking problem, even that may be too much. Check with your healthcare provider to make sure you are taking the right amount if you have either of these medical issues.
A Word From Verywell
The take-home message here is to always read the labels and follow the dosage instructions when taking medicine. This goes for both over-the-counter and prescription medications.
Tylenol is generally a safe and effective pain reliever for mild headaches and other aches and pains. But it can be fatal in large doses. This doesn’t mean you should avoid it. Instead, use it sensibly and properly.
