1. WHAT NAPROXEN IS AND WHAT IT IS USED FOR
Naproxen belongs to a group of medicines called non-steroidal anti-inflammatory drugs (NSAID). It is a painkiller and antipyretic (reduces fever). Naproxen works by reducing inflammation and relieving pain, swelling and stiffness in the joints and muscles. There are a number of painful conditions that can affect your joints and muscles, which can be helped by taking Naproxen. These conditions include:
- rheumatoid arthritis including childhood rheumatoid arthritis
- ankylosing spondylitis (arthritis in the spine)
- musculo-skeletal disorders such as sprains, strains and other injuries, such as backache or neckache
- period pain
2. BEFORE YOU TAKE NAPROXEN Do not take Naproxen
- if you are allergic (hypersensitive) to naproxen or any of the other ingredients in these tablets (these are listed in section 6)
- if you have taken another non-steroidal anti-inflammatory drug before (including Aspirin) and suffered an unpleasant or allergic reaction including asthma, redness and itching of the skin or an itchy, running nose
- if you have a stomach ulcer or know that you have suffered with ulcers in the past
- if you have severe heart failure, a disease of the heart that causes shortness of breath and swelling of the feet or legs due to fluid build up
- if you have recently become pregnant
Take special care with Naproxen
- if you suffer from bronchial asthma or from allergies
- if you have any problems with your stomach or bowel
- if you have problems with your blood not clotting
- if you have problems with your liver or kidneys or have to be careful not to take too much sodium in your diet.
Tell your doctor if any of the above applies to you.
It is important that you use the lowest dose that controls your pain and you should not take Naproxen for longer than necessary to control your symptoms. Some anti-inflammatory/pain- relieving medicines may be associated with a small increased risk of heart attack (“myocardial infarction”) or stroke, especially when used at high doses and in long-term treatment. Although Naproxen (1000mg daily) may be associated with a lower risk, some risk is still possible
- if you have heart problems including heart failure, angina (chest pain), or if you have had a heart attack, bypass surgery, peripheral artery disease (poor circulation in the legs or feet due to narrow or blocked arteries), or any kind of stroke (including ‘mini-stroke’ or transient ischaemic attack “TIA”) you should discuss this with your doctor before taking Naproxen.
- you should also discuss your treatment with your doctor if you have high blood pressure, diabetes, high cholesterol, have a family history of heart disease or stroke, or if you are a smoker. Your doctor will want to ensure that you take the lowest necessary dose of Naproxen for the shortest period necessary.
Please tell your doctor or pharmacist if you are taking or have recently taken any other medicines, including medicines obtained without a prescription, or any of the following:
- Phenytoin to treat or prevent convulsions, anticoagulants to thin your blood, such as Warfarin or sulphonamides to treat infection, as the levels of all these medicines in your blood may increase when you start taking Naproxen
- Furosemide or other “water tablets”, as these may not work as well when you start taking Naproxen Lithium to treat mental illness or Methotrexate, for psoriasis, as your body may not be able to clear these as quickly when you start taking Naproxen
- medicines to lower your blood pressure or to treat a heart condition
- Probenecid, for gout, as the dose of Naproxen you will need will be lower than usual
- antibiotics, to treat infection, as side effects may occur if some antibiotics are taken with Naproxen
- Digoxin for your heart; corticosteroids such as Ciclosporin and Prendisolone; Mifepristone or if you are already taking other non-steroidal anti-inflammatory drugs
You should swallow Naproxen whole with a glass of water, with or after food. Do not crush or chew. Pregnancy and breast-feeding
Naproxen may make it more difficult to become pregnant. You should inform your doctor if you are planning to become pregnant or if you have problems becoming pregnant. Tell your doctor if you are breastfeeding, as small amounts of Naproxen can pass into breast milk. Ask your doctor or pharmacist for advice before taking any medicine.
Driving and using machines - Do not drive or operate machinery if you suffer from side effects such as dizziness, drowsiness, fatigue and visual disturbances.
Effects on laboratory tests
If you need to have any tests such as blood tests, urine tests, liver function or adrenal function tests tell the doctor that you are taking Naproxen. You may need to stop taking these tablets before you have the test.
