About naproxen

What is naproxen used for?

Naproxen is a type of analgésique anti-inflammatoire called non-steroidal anti-inflammatory drugs (NSAIDs), or just 'anti-inflammatories'.

It is used to treat painful conditions such as l'arthrite, les entorses et les foulures, backache, period (menstrual) cramps, and douleur de la goutte.

Naproxen is available on prescription. Short courses of tablets for the treatment of period pain are also available to buy at pharmacies.

How does naproxen work?

Naproxen works by blocking the effect of chemicals in your body, called cyclo-oxygenase (COX) enzymes. These enzymes help to make other chemicals in the body, called prostaglandins.

Certaines prostaglandines sont produites aux sites de blessure ou de dommage, et provoquent douleur et inflammation. En bloquant l'effet des enzymes COX, moins de prostaglandines sont produites, ce qui signifie que la douleur et l'inflammation sont atténuées.

How to take naproxen

• Before you start taking naproxen, read the manufacturer's printed information leaflet from inside the pack for information about your tablets and a full list of side effects which you may experience from taking them.

• Make sure you take the tablets exactly as your doctor or pharmacist tells you to:

  • Long-term conditions (such as arthritis): 500 mg-1 g daily, as one or two doses.

  • Short-term pain (muscle pain, sprains, period pain): usually 250 mg, taken 3-4 times daily. First dose may be 500 mg.

  • For gout, the usual dose is 750 mg for the first dose, and then 250 mg every eight hours until the attack has passed.

  • If you have bought naproxen over the counter for period pain, take 250 mg three times daily, for a maximum of three days.

  • The dose of Vimovo® is one tablet twice daily before meals.

  • Doses for children depend upon the age of the child.

• Take with food, milk, or water to reduce stomach upset (except Vimovo®, which should be taken 30 minutes before a meal).

• Some brands of naproxen are specially coated (enteric-coated (EC) tablets) to protect your stomach from irritation. Do not chew or break the tablets, as this will stop the coating from working properly.

• For enteric-coated (EC) tablets, avoid antacids 2 hours before and after taking them.

• If you miss a dose, take it as soon as you remember unless it’s almost time for your next dose. Ne prenez pas deux doses ensemble.

Tirer le meilleur parti de votre traitement

• Votre médecin vous prescrira la dose la plus faible pour la durée la plus courte afin de réduire les effets secondaires.

• For long-term use you may be given another medicine to protect your stomach, or a combination product such as Vimovo®, which includes stomach protection.

• Keep regular appointments with your doctor, especially if you are taking naproxen long term.

• If you have asthma and develop wheezing or breathing problems, stop taking naproxen and see your doctor as soon as possible.

• Check with a pharmacist before taking other medicines. Do not take naproxen with other anti-inflammatory painkillers, including some cold and flu remedies.

• Si vous subissez une opération ou un traitement dentaire, informez la personne qui effectue le traitement des médicaments que vous prenez.
