What are Naproxen tablets?

Maximum quantity per treatment - 112 tablets 

Naproxen has been used to treat a variety of pain and inflammation conditions since 1976, it is considered the first line treatment for gout, musculoskeletal pain, inflammation, and dysmenorrhea (period pain).

Naproxen is a non-steroidal anti-inflammatory drug (NSAID) which is used to provide pain relief for a variety of conditions ranging from arthritis to Gout.

Naproxen tablets are available in a number of different strengths, ranging from 250mg to 500mg. Naproxen 500mg is typically the strongest strength of Naproxen available.

For more information, read our guide to Naproxen which explains everything you need to know.

What are Naproxen tablets used to treat?

Naproxen 500mg is usually prescribed when over the counter options such as paracetamol have failed to relieve symptoms. 

It is used to treat the below conditions:

  • period pain 
  • arthritis
  • muscle/joint pain
  • back pain
  • Gout
  • Sprains and strains

In most cases, paracetamol is the most effective pain relief medicine for treating mild to moderate pain. Naproxen over the counter is available in lower doses, without a prescription, and may be a treatment option before moving onto the higher strength doses such as Naproxen 500mg and 250mg tablets.

It is also safe for children when taken under medical supervision to treat the following:

  • Period pain for girls of any age
  • Diseases of the joints in children aged 2 years old and over
  • Muscle and bone disorders in babies who are older than 1 month

How does naproxen work?

Like most anti-inflammatory drugs, naproxen works by reducing the hormones in your body that cause pain and inflammation.

Naproxen works by inhibiting the cyclooxygenase (COX) enzymes that help the body produce another natural chemical called prostaglandins. As part of the body’s natural healing process, prostaglandins are responsible for causing pain and inflammation at the source of an injury.

However, this natural healing response by the body can sometimes lead to excessive production of prostaglandins and contribute to unwanted pain and inflammation in certain parts of the body. Excessive production of prostaglandins is directly linked to conditions such as arthritis, painful menstrual cramps, and heavy menstrual bleeding.

By inhibiting the cyclooxygenase (COX) enzymes, the production of prostaglandins is decreased, as a result; pain and inflammation is also reduced.

Naproxen Dose

The dosage you require will depend on the kind of pain you are taking Naproxen for, as well as your age and whether you have any pre-existing conditions.

The Naproxen dose as per the NICE guidelines:

Taking Naproxen tablets with other pain relief medicine

Read our detailed guide on the differences between Naproxen, Paracetamol and Ibuprofen and if they can be taken together.

Who can take Naproxen tablets?

Naproxen tablets may not be a suitable pain relief medicine for everyone. It is also possible that certain Naproxen doses may not be suitable for your condition. For example, your doctor may choose to prescribe Naproxen 500mg tablets instead of the lower 250mg dose if your condition is more severe. Likewise, if your condition does not require the stronger dose of Naproxen, you may be prescribed Naproxen 250mg tablets.

In other instances, your doctor may decide that the prescription strengths of Naproxen are not needed and instead recommend over the counter Naproxen which is typically a lower strength version of the medicine.

  • You are in the late stages of pregnancy
  • You have had bleeding or perforation in your stomach while previously taking a non-steroidal anti-inflammatory drug (NSAID)
  • You have severe liver, kidney, or heart problems
  • You have ever had, or currently have, any stomach problems, such as an ulcer or bleeding

  • You have any kidney or liver problems
  • You have any problems with blood clotting
  • You have lumps in your nose (polyps), you sneeze a lot, have a runny, blocked, or itchy nose

How long does Naproxen last?

Naproxen will stay in your system for approximately 93.5 hours. This may seem like a very random number; however, it is calculated using the half-life of Naproxen, which is 12 to 17 hours, typically the body will require 5.5 half-lives to remove the active ingredient from the body. In this case, we take the half-life of Naproxen which is 12 to 17 hours and multiply it by 5.5 to get to the 93.5 hours until Naproxen is removed by the body.
