1.    What Naproxen EC is and what it is used for

Naproxen EC tablets contain the active substance naproxen, which belongs to a group of medicines called non-steroidal anti-inflammatory drugs (NSAIDs). These medicines help to relieve pain and joint inflammation.

Naproxen EC can be used in adults for the treatment of rheumatoid arthritis, osteoarthritis, ankylosing spondylitis (causing pain and stiffness in the back), back pain, neck pain, and swollen or painful tendons. It is also used to treat sprained or strained muscles or painful menstrual periods.

2.    What you need to know before you take Naproxen EC

Do not take Naproxen EC if you:

•    are allergic to naproxen or any of the other ingredients of this medicine (listed in section 6).

•    have or ever had a stomach ulcer, or bleeding of the stomach or intestine.

•    have previously experienced bleeding or perforation in your stomach while taking NSAIDs.

•    have ever suffered any allergic reactions after taking aspirin or other NSAIDs or if you have a history of swelling of the tongue or larynx (angioedema), wheeziness (asthma) inflammation of the nose (rhinitis) or nasal polyps (Lumps lumps in nose), hay fever, itchiness or skin rash (urticaria) after taking aspirin or other NSAIDs

•    have severe problems with your kidneys, liver or heart.

•    are in the last three months of pregnancy.

Do not take Naproxen EC if any of the above applies to you. If you are not sure, talk to your doctor or pharmacist before taking Naproxen EC.

Warnings and precautions

Talk to your doctor or pharmacist before taking Naproxen EC if you:

•    suffer from stomach problems. It is known that bleeding in the stomach or gut can occur in patients taking Naproxen EC. If you find you have black, tarry stools while taking these tablets, you must stop taking them and tell your doctor at once.

•    have asthma, hay fever or allergies as these tablets can cause breathing difficulties (bronchospasm).

•    are having liver or adrenal function tests as taking these tablets can change the results.

•    suffer from any blood clotting disorders or are taking anti-coagulant therapy (blood thinning medicines) e.g. heparin or warfarin, as naproxen decreases the ability of your blood to clot and will increase the length of time you bleed if you get a cut.

•    have heart problems. Occasionally patients have reported swollen feet or hands while taking these tablets and this is more likely in patients who have heart problems.

•    have problems with the blood vessels (arteries) anywhere in your body.

•    have kidney problems. Your doctor may wish to check your kidney function before and during treatment and/or use a lower dose than normal.

•    have liver problems, including alcohol-related disease or other forms of cirrhosis of the liver, as you should then take the least number of tablets needed.

•    are elderly and/or feeling weak (perhaps because of an illness). These patients are more susceptible to side effects of NSAIDs especially bleeding and perforation in the stomach or gut. Long term use of Naproxen in these patients is not recommended.

•    have an autoimmune condition, such as 'systemic lupus erythematosus' (SLE, causes joint pain, skin rashes and fever) and ulcerative colitis or Crohn's disease (conditions causing inflammation of the bowel, bowel pain, diarrhoea, vomiting and weight loss).

If any of the above applies to you, or if you are not sure, talk to your doctor or pharmacist before you take Naproxen EC.

While taking this medicine if you develop visual disturbances, talk to your doctor and go for ophthalmological examination.

Please note:

Medicines such as Naproxen EC may be associated with a small increased risk of heart attack (“myocardial infarction”) or stroke. Any risk is more likely with high doses and prolonged treatment. Do not exceed the recommended dose or duration of treatment.

If you have heart problems, previous stroke or think that you might be at risk of these conditions (for example if you have a high blood pressure, diabetes or high cholesterol or are a smoker) you should discuss your treatment with your doctor or pharmacist.

Children and adolescents

Naproxen EC is not recommended for use in children under 16 years of age.

•    mifepristone (used to end pregnancy or to bring on labour if the baby has died)

•    zidovudine (used to treat AIDS and HIV infections).

Pregnancy, breast-feeding and fertility

Do not take Naproxen if you are in the last three months of pregnancy, as it can harm your baby.

If you are pregnant or breast-feeding, think you may be pregnant or are planning to have a baby, ask your doctor or pharmacists for advice before taking this medicine.

Talk to your doctor before taking Naproxen if you are up to six months pregnant. Your doctor will then discuss this with you and decide whether you should take this medicine. Naproxen may make it more difficult to become pregnant. You should tell your doctor if you are planning to become pregnant or if you have problems becoming pregnant.

If you are breast feeding you should not take these tablets.

Ask your doctor or pharmacist for advice before taking any medicines.

3. How to take Naproxen EC

Always take this medicine exactly as your doctor or pharmacist has told you. Check with your doctor or pharmacist if you are not sure. The number of tablets you should take depends on the type of pain you have.

Do not take more than you are told to, as this increases the chances of side-effects (especially in the elderly).


For rheumatoid arthritis, osteoarthritis, and ankylosing spondylitis The recommended dose is between 500 mg and 1 g each day in two separate doses, 12 hours apart. Where 1 g per day is needed, you can take 500 mg twice each day, or 1 g in one single dose (morning or evening).

In some people, a larger dose of between 750 mg and 1 g per day may be taken to start with to control the pain. This is in patients with:

•    severe night-time pain and/or morning stiffness.

•    if your tablets have recently been changed from a high dose of another treatment for pain.

•    osteoarthritis where pain is your main problem.

For strained or sprained muscles, back pain, neck pain, swollen or painful tendons, and painful periods

The recommended starting dose is 500 mg, followed by 250 mg every 6 to 8 hours as needed. Do not take more than 1250 mg a day after the first day.

Elderly and people with liver and kidney problems

Your doctor will decide your dose; it will usually be lower than that for adults.

Use in children and adolescents

Naproxen EC is not for use in children under 16 years of age.

Medicines such as Naproxen EC may be associated (linked) with a small increased risk of heart attack ('myocardial stroke') or stroke. Any risk is more likely with higher doses and prolonged (longer term) treatment. Do not exceed (take more than) the recommended dose or duration (length) of treatment.

Swallow the tablets whole with a little water, with or after food. Do not crush or chew tablet.
