Extra Strength Tylenol Use and Overdose

Extra Strength Tylenol is a popular over-the-counter medication used to relieve pain, including arthritis pain.

However, you must be careful not to exceed the maximum daily dose, as an overdose can be toxic to the liver.

This article explains how Extra Strength Tylenol differs from regular strength Tylenol or Tylenol Arthritis Pain.

It also outlines the maximum dose recommended for adults and children as well as the signs and symptoms of a Tylenol overdose.

Available Strengths

When you go to the local drugstore, you will see many different types of pain relievers. Tylenol is different from products like aspirin or Advil (ibuprofen) as it is not a nonsteroidal anti-inflammatory drug (NSAID).

Instead, it is referred to as an analgesic used for pain relief and has an altogether different mechanism of action from NSAIDs.

There is not just one kind of Tylenol—several strengths are sold over the counter.

All products labeled Tylenol contain acetaminophen as their active ingredient.

The difference in Tylenol products is related to the amount of acetaminophen in each tablet, capsule, or gelcap. This is measured in milligrams (mg).

The strengths of Tylenol products are as follows:

• Each Regular Strength Tylenol contains 325 mg acetaminophen.
• Each Extra Strength Tylenol contains 500 mg acetaminophen.
• Each Tylenol Arthritis Pain contains 650 mg acetaminophen.

Directions for Use 

Adults and children 12 years and over should take two tablets, capsules, or gelcaps every six hours as needed, with no more than six tablets, capsules, or gelcaps in 24 hours.

Adults have a maximum daily dose of Tylenol (acetaminophen) of 3 grams (3,000 mg).

It is recommended that children read the packaging carefully and consult their healthcare provider for proper dosage.

In 2011, the makers of Tylenol lowered the maximum allowable daily dose of Tylenol from 4 grams (4,000 mg) to 3 grams (3,000 mg) to encourage safe usage.

Tylenol should not be taken for more than 10 days in a row.

If you need to treat pain on an ongoing basis, speak with your doctor for the safest and most effective option for you as an individual.

Acetaminophen may provide some immediate relief but is not considered a long-term solution.

Overdose Symptoms

Taking too much acetaminophen can be deadly because it can lead to hepatotoxicity (liver toxicity).

Because Tylenol is available over the counter, acetaminophen overdose is one of the most common types of overdose around the world today.

The liver is responsible for converting and clearing many chemicals from the body, including drugs like acetaminophen.

When these chemicals are consumed in excess, the liver is "overwhelmed" and cannot clear the chemicals properly. Instead, the chemicals start to accumulate and cause damage to the liver.

Drinking alcohol with acetaminophen only increases the risk of hepatotoxicity, even at lower doses. For this reason, alcohol should never be consumed while you are taking Tylenol.

Signs and symptoms of acetaminophen-induced hepatotoxicity include:

• Nausea
• Diarrhea
• Vomiting
• Upset stomach
• Sweating
• Abdominal pain
• Coma

Symptoms often develop 12 hours or more after a significant overdose. Because drug-induced hepatotoxicity can cause permanent, irreversible liver damage—and even death—it is imperative that you go to the nearest emergency room if an overdose is suspected.

Summary

Extra Strength Tylenol is a popular over-the-counter pain reliever stronger than regular Tylenol but less potent than Tylenol Arthritis Pain.

Each tablet, capsule, or gelcap contains 500 milligrams (mg) of acetaminophen.

Extra Strength Tylenol can be used in adults and children 12 years and over.

As needed, the recommended dose is two tablets, capsules, or gelcaps every six hours. The maximum daily dose is six tablets, capsules, or gel capsules.

Never take Tylenol for more than ten consecutive days without first speaking with your doctor.

Taking more than the recommended dose can lead to liver toxicity and liver damage. The risk of this is increased if you take Tylenol with alcohol.
