What Is Naproxen?
Naproxen is a painkiller medicine that specifically targets inflammatory pains. It belongs to a medicine class known as non-steroidal anti-inflammatory drugs (NSAIDs). Other medicines in this category include ibuprofen, aspirin and diclofenac. Typically people find that Naproxen provides more inflammatory pain relief than ibuprofen or aspirin.
Depending on the pain severity, 250mg or 500mg doses are available. The lowest effective dose should be used to minimise the chance of side effects. Pain and inflammation should be noticeably reduced in 30-60 minutes after taking a dose of Naproxen.
It is only available on prescription, although you can buy it over the counter for period pain and menstrual cramps from a pharmacy under the brand name Feminax Ultra.
What Is Naproxen Used For?
It is commonly prescribed for pain relief and to treat inflammation in conditions such as gout, rheumatoid arthritis, sprains and strains and osteoarthritis. Because NSAIDs do not have the potential to cause addiction such as opioid-based painkillers, it is the preferred treatment for those who suffer inflammatory pain. Naproxen (or other NSAIDs) along with paracetamol may make up the base of pain relief treatments before using potentially addictive medicines.
How Does Naproxen Work?
Non-steroidal anti-inflammatories such as Naproxen work by reversibly stopping enzymes in the body responsible for producing an inflammation causing substance known as prostaglandins. Prostaglandins usually signal the body to induce inflammation, by reducing their numbers in the body by slowing their production, inflammation is reduced.
Naproxen, Paracetamol & Other Painkillers
Yes, Naproxen can be taken alongside paracetamol or paracetamol/codeine combinations such as co-codamol. However, it should not be taken with ibuprofen, aspirin, or diclofenac because they are from the same class of medicines (NSAIDs) and will cause increased side effects that may be dangerous.
It is important to note that many other medicines can contain NSAIDs or paracetamol in combination such as cold and flu medicines. This can lead to accidental double doses that can result in side effects. Always ensure you are aware of what is in each medicine you take before use.
As with all pain medicines, it is best to use the lowest effective dose required to avoid the potential side effects of treatments.
Naproxen Dose
You should take it exactly as your doctor has told you to. The dose may vary from person to person depending on why your doctor has prescribed it. The usual Naproxen dosage is to take a dose twice a day with food.
Two strengths are available: Naproxen 250mg and Naproxen 500mg. Your doctor will decide the safest strength and dose for you. Usually, you should take the lowest effective dose for the shortest time. However, some people can be prescribed Naproxen long-term to relieve pain in chronic conditions.
If you have been prescribed Naproxen for a long time, it is important that you are aware of the ways to protect yourself from the potential side effects. Refer to warnings and precautions for more information.
Regular or Gastro-Resistant Naproxen
Naproxen is available as regular tablets or as gastro-resistant tablets. The gastro-resistant tablets have a coating that protects them from stomach acid and releases the drug later on in the gut. This can help to protect the stomach from being irritated by the drug.
