Tylenol Arthritis Vs. Tylenol Extra Strength: What Is The Difference?

Hello and thank you for reaching out to us!

There are two main differences between Tylenol Extra Strength and Tylenol Arthritis.

• The amount of acetaminophen (the active ingredient) contained in each
• How long a dose lasts

I discuss these differences below.

Strength Difference

The first main difference between Tylenol Extra Strength and Tylenol Arthritis is their respective strengths:

• Tylenol Extra Strength contains 500mg acetaminophen per tablet
• Tylenol Arthritis contains 650mg acetaminophen per tablet

For reference, 'regular strength' Tylenol contains 325mg acetaminophen per tablet.

Below are the 'drug facts' for each product, showing the difference in strength.

Now, even though Tylenol Arthritis contains more acetaminophen per dose, it is released from the tablet (or caplet) over a longer period of time than Tylenol Extra Strength, and I discuss this in the next section.

Duration Of Action & Dosing

Tylenol Arthritis is an extended-release formulation and each tablet releases acetaminophen over an 8-hour window. Tylenol Extra Strength, on the other hand, is immediate-release.

Due to the differences in their drug-release mechanism, the products are recommended to be dosed as follows:

• Tylenol Arthritis: 1-2 tablets every 8 hours.
• Tylenol Extra Strength: 1-2 tablets every 4-6 hours.

Tylenol Arthritis is sometimes referred to as 'Tylenol 8-Hour', as that is the approximate duration of action. Tylenol Extra Strength, being an immediate release product, generally lasts around 4 to 6 hours per dose.

Maximum Tablets Per Day

The recommended maximum daily dose of acetaminophen is 4,000 mg per day for most adults. This equates to:

• A maximum of 8 tablets of Extra Strength Tylenol per day
• A maximum of 6 tablets of Tylenol Arthritis per day

Final Words

Thanks again for your question!

I hope this answer helped!

The takeaway is that these are both similar products, with just some slight differences in strength and duration of action.

In regard to arthritis, it is more of a chronic condition, and has to be treated as such.

Taking a pain reliever that releases slowly over time, and therefore lasts longer, (like Tylenol Arthritis) is generally a better option than taking something intended to be used from minor aches and pains on an 'as-needed basis' (like Tylenol Extra-Strength).

The American College of Rheumatology actually recommends acetaminophen as a first-line treatment for osteoarthritis of the knee and hip, so Tylenol Arthritis, with its long duration of action, is a good choice for most individuals.
