Is ibuprofen or tylenol worse for your liver

Most things in life are about balance and moderation, and pain killers are no different. While Advil, Motrin and Tylenol offer relief when you’ve tweaked your neck or have a fever, taking too much of these medications can have serious health consequences, one of which is liver damage. But how much exactly is too much?

Acetaminophen, the active ingredient in Tylenol, is the one most closely linked to liver problems. The U.S. Food and Drug Administration warns against using higher than the recommended dose, even in the short-term; using more than one product containing the drug; or combining the drug with alcohol. “FDA believes that consumers need to know that these products can cause serious side effects, such as severe liver injury and stomach bleeding, when used improperly.” The maximum safe dose of extra strength Tylenol for adults, as per the company’s website, is 3,000 milligrams per day, or six pills. That’s lower than it used to be — Tylenol explains that the old dosage limit was 4,000 milligrams a day, and that it now recommends taking only two pills every six hours, when previously it said four to six hours.

Although the liver is the only organ that can regenerate damaged tissue, interfering with its function is dangerous, as it cleans the blood, helps to digest food and fights off infection. You’ll know your liver is damaged if your skin and the whites of your eyes turn yellow, a condition called jaundice that comes when the liver is not filtering out a yellowish substance called bilirubin and it builds up in the blood. Jaundice also makes urine dark and stool pale. Other symptoms of liver damage include itchy skin, swelling in the abdomen and legs, and bruising easily because the liver has stopped producing blood clotting proteins.

But sometimes the body shows no symptoms of liver damage at all, or only vague symptoms like fatigue. That can be dangerous because liver troubles that go untreated could become dangerous. The American Liver Foundation says that blood vessels leading to the liver can burst; and toxins can build up in the brain and interfere with mental function. “There is a risk of coma and death.”

Harvard Medical School explains that the main risk of liver damage from acetaminophin is from large doses, “but there are reports of people developing liver problems after taking small to moderate amounts of acetaminophen for long periods of time. Drinking alcohol while taking acetaminophen can also cause liver damage.”

What happens to the liver exactly? The Mayo Clinic says exposure to too much medication can cause toxic hepatitis, an inflammation in the liver. When the liver breaks down drugs and chemicals in the bloodstream, the byproducts of the process could hurt the organ. Constant exposure to those dangerous byproducts can cause the inflammation, which could permanently damage the liver by scarring it or sending it into organ failure. “In some cases, toxic hepatitis develops within hours or days of exposure to a toxin,” the organization says. “In other cases, it may take months of regular use before signs and symptoms appear.”

While much health literature refers specifically to the potential of acetaminophen to cause liver damage, ibuprofen, the active ingredient in Advil and Motrin, appears to do the same in some rare cases. Motrin, for example, advises people on its warning label to seek a doctor’s advice before taking the medication if they have liver cirrhosis, a condition marked by tissue scarring. However, the U.S. National Library of Medicine explains that ibuprofen is one of the safest and most easily tolerated nonsteroidal anti-inflammatory drugs, also known as NSAIDs. Still, it can “rarely cause clinically apparent and serious acute liver injury,” the federal institute says. But most of those cases might be attributable to an “immunoallergic” reaction and most ibuprofen overdoses do not present with liver injury.

To avoid liver damage associated with any pain reliever, the FDA advises following recommended dosage guidelines.

Chances are, acetaminophen is a mainstay in your medicine cabinet. You use it to ease aches and pains or bring down a fever.

When you follow the instructions on those pill-bottle labels, it's helpful and safe, and it generally doesn't upset the stomach like other pain relievers.

But if you take too much, it can hurt your liver. In extreme cases, it can even cause liver failure.

It’s still fine to use acetaminophen. You just need to know how to do that safely.

What’s It In?

More than 50 million Americans use acetaminophen each week. It's the most widely used drug ingredient in the U.S., found in more than 600 prescription and over-the-counter (“OTC”) medications, including allergy pills, cold medicines, cough syrups, headache pills, and sleep aids.

Never take more than one product at a time that’s made with acetaminophen. For instance, if it’s in your headache pill and your cold medicine, and you take them both, you could get more than you should.

Check the “Active Ingredients” section of the “Drug Facts” box on your OTC medication, or the label on your prescription, where it may be called “APAP” or “acetam.”

Follow the Directions

Read the label on your medication. Don’t take more than directed, even if you’re still in pain or don't feel well.

Even when you stick to the recommended dose, you shouldn’t take acetaminophen for more than 10 days for pain, or 3 days for fever. If you still feel like you need relief, call your doctor, nurse, or pharmacist.

Adults should not get more than 4,000 milligrams of acetaminophen per day from all sources. That’s no more than 12 regular-strength pills at 325 milligrams per pill, or 8 extra-strength pills at 500 milligrams per pill.

For children, the daily limit depends on their weight and age. Check how many milligrams are in your child’s doses, and follow the directions on the label exactly.

You may need to switch your child’s weight from pounds to kilograms -- you can use an online calculator to do that. If you're not sure how much is OK, ask your doctor or pharmacist. To help you keep track, write down all the medicines you give your child each day.

Common reasons people mistakenly pass the daily limit include:

  • They take too much at once.
  • They don’t wait long enough between doses.

Talk to Your Doctor

If you have more than three alcoholic drinks a day or have liver disease, ask your doctor before you take anything that has acetaminophen in it. In these cases, even the recommended dose could make liver damage more likely.

5 Overdose Warning Signs

If you think you may have accidentally taken too much acetaminophen, you may have:

  1. Nausea
  2. Loss of appetite
  3. Vomiting
  4. Sweating
  5. Diarrhea

These symptoms may not start until hours after you've taken the drug. By the time you notice something’s wrong, your liver may already be severely damaged.

If you have questions about whether you took the right amount, call your local poison control center, which will tell you if you need to go to the ER. If you think someone may have overdosed, call 911.

Is Tylenol or ibuprofen better for liver disease?

But if you have a history of liver problems, it's usually recommended to avoid acetaminophen. Ibuprofen is harder on the kidneys than acetaminophen. Acetaminophen doesn't have the same effect on the COX pathway as ibuprofen. So kidney damage is much more rare.

Which pain reliever is most harmful to the liver?

Any NSAID (non-steroidal anti-inflammatory drug) can cause liver injury, although it's very rare. This class of medications includes popular drugs like ibuprofen and naproxen. But when it comes to liver injury, diclofenac is the NSAID with the highest risk.

What pain relievers are easy on the liver?

Contrary to many peoples beliefs, acetaminophen can be used in patients with chronic liver disease (CLD). Most experts suggest up to 2 grams of acetaminophen a day in non-consecutive days can be safely used.

Why do doctors recommend Tylenol over ibuprofen?

Ibuprofen can also damage the kidneys and cause high blood pressure, especially when large doses are taken over a prolonged period. The biggest risk with acetaminophen is liver damage when very high doses are taken. This can lead to liver failure and death if prompt medical attention is not sought after an overdose.
