How to take Naprosyn
Please read the enclosed leaflet before taking Naprosyn tablets.
For short term muscular pain and inflammation and for period pains in adults, the recommended dose is two 250mg tablets initially, followed by a further 250mg tablet every six to eight hours as needed. The maximum recommended dose each day is five tablets (1250mg).
For rheumatic diseases, the recommended dose is one or two 250mg tablets, twice a day.
For acute gout attack, the recommended dose is three 250mg tablets initially, then a further 250mg every eight hours until the attack has passed. The maximum recommended dose each day is five tablets (1,250mg). To prevent side effects, the lowest effective dose and duration should be used to control your symptoms. Swallow the tablets with water, with or after food to minimise stomach discomfort. The tablets should not be broken, crushed or chewed.
Because Naprosyn treatment can be harmful to the stomach, and especially if you are at a higher risk of stomach side effects, we recommend that you also take another medicine to protect the stomach while you are taking Naprosyn, such as Omeprazole 20mg Capsules or Zoton FasTab 30mg Tablets (lansoprazole). These are taken once a day. People at a higher risk of side effects relating to the stomach include those who:
- Are heavy drinkers and smokers
- Are over the age of 65
- Are taking the maximum recommended dose of ibuprofen
- Have other medical conditions including diabetes, heart disease, high blood pressure and liver or kidney problems
- Have suffered from a history of stomach problems
Is Naprosyn suitable for me?
In certain situations, Naprosyn, like all medicines, should be used with caution or may not be recommended at all.
Do not take Naprosyn if:
- You are allergic to naproxen or any of the other ingredients of this medicine
- You are known to have an ulcer or bleeding in your stomach or intestines
- As a consequence of taking aspirin or any other anti-inflammatory and pain-relieving medicine (NSAID), you have contracted asthma, a runny or blocked nose, nasal polyps, or an allergic reaction such as an itchy rash of the skin, swelling of the face, lips, tongue or throat or breathing difficulties
- You are pregnant. If you find out you’re pregnant during ongoing treatment, it’s advised that you discuss methods of contraception with your doctor
- You are breastfeeding
- You have severe heart failure, liver failure or kidney failure
- You have any medical condition that involves an increased tendency to bleed
Check with your doctor or pharmacist before taking Naprosyn if you:
- Have ever had an ulcer or bleeding in your stomach or intestines
- Have been known to struggle with any other stomach or gut problems (ulcerative colitis or Crohn’s disease, for example)
- Have, or have previously had, various problems with your heart or circulation, including high blood pressure
- Smoke, or have conditions including high cholesterol or diabetes
- Take a low dose of aspirin each day as advised by your doctor
- Take any other medicines, including steroids, anticoagulants such as warfarin, antidepressants, diuretics (water tablets), or other medicines for your heart or circulation
- Have, or have had, bronchial asthma or an allergic disease
- Have SLE (systemic lupus erythematosus) or a connective tissue disorder
- Are female and are trying to conceive
- Have issues with the function of heart, liver or kidneys - your doctor may want to keep a regular check on you
- Have fluid retention (such as swollen ankles and feet)
- Have an infection or think you may have an infection due to feeling ill, as you may find it difficult to spot a fever or other signs of infection and inflammation while taking naproxen.
Naprosyn, like other NSAIDs, has been found to bring on symptoms of asthma in patients who have, or have a history of, bronchial asthma.
Elderly patients are more likely to experience side effects or other problems with Naprosyn, especially perforation or bleeding in the stomach.
If you are trying to conceive, Naprosyn may make it more difficult to become pregnant. It’s advised that you inform your doctor if you are planning to become pregnant or if you’re having problems in becoming pregnant before committing to this treatment.
It is vital that, during your consultation, you tell us if you are currently on any other medicines, whether they’re prescribed by your doctor or purchased from a pharmacy without a prescription. These tablets may cause problems if they’re taken alongside certain other medicines, including:
- Celecoxib, aspirin, diclofenac, ibuprofen and other NSAID medicines
- Diuretics, beta-blockers and medicines for blood pressure
- Digoxin or other cardiac glycosides that are used to treat heart conditions
- Certain oral medicines taken for diabetes, such as gliclazide, glipizide, glibenclamide, glimepiride, or tolbutamide
- Lithium (which is used to treat certain types of depression)
- Methotrexate (which you might be taking to treat rheumatoid arthritis, psoriasis or leukaemia)
- Probenecid (which is used to treat gout)
- Ciclosporin and tacrolimus (used for immune system suppression – following transplants, for instance)
- Oral steroids including prednisolone
- Warfarin or any other oral anticoagulants (“blood-thinning” agents that reduce blood clotting), or clopidogrel
- Antibiotics, particularly those that ending in “-floxacin” (quinolone antibiotics)
- Some antidepressants, known as selective serotonin reuptake inhibitors (SSRIs)
- Zidovudine (which is a treatment for the HIV infection)
You should not use Naprosyn if you are pregnant or suspect you might be pregnant, or are breastfeeding, or planning to, unless specifically advised by your doctor.
Please be sure to give a full picture of your general health in your consultation, as this provides the doctor with all the information required to assess your suitability for Naprosyn.
