2. Important information before using Naproxen 250 H or Naproxen 500 H

H

When not to use Naproxen 250 H or Naproxen 500 H

  • if the patient is allergic to naproxen or any of the other ingredients of this medicine (listed in section 6) and to other non-steroidal anti-inflammatory drugs (NSAIDs);
  • in patients who have had allergic symptoms in the past, such as rhinitis, urticaria or bronchial asthma, during treatment with acetylsalicylic acid or other non-steroidal anti-inflammatory drugs;
  • in patients with severe liver, kidney or heart failure;
  • in patients with active or past peptic ulcer of the stomach and (or) duodenum, perforation or bleeding, also occurring after the use of NSAIDs;
  • in the third trimester of pregnancy;
  • in patients with bleeding disorders.

Warnings and precautions

  • Taking the medicine in the smallest effective dose and for the shortest possible time necessary to alleviate symptoms reduces the risk of side effects. Patients who are long-term treated with NSAIDs should undergo regular medical check-ups to detect any potential side effects of treatment.
  • Taking medicines such as naproxen may be associated with a small increased risk of heart attack (myocardial infarction) or stroke. This risk increases with long-term use of high doses of the medicine. Do not use higher doses and longer treatment than recommended.
  • In case of heart disorders, past stroke or suspected risk of these disorders (e.g. high blood pressure, diabetes, increased cholesterol, smoking), you should discuss treatment with your doctor or pharmacist.
  • There is a risk of gastrointestinal bleeding, ulceration or perforation, which can be fatal and do not necessarily have to be preceded by warning symptoms, or may occur in patients who have had such warning symptoms. In case of gastrointestinal bleeding or ulceration, the use of the medicine should be discontinued. Patients with a history of gastrointestinal diseases, especially the elderly, should inform their doctor about any unusual gastrointestinal symptoms (especially bleeding), especially during the initial treatment period.
  • Concomitant use of naproxen and other non-steroidal anti-inflammatory drugs is not recommended due to the increased risk of serious side effects characteristic of this group of medicines.
  • Naproxen belongs to a group of medicines (NSAIDs) that may adversely affect female fertility. This effect is transient and disappears after the end of treatment.
  • Naproxen inhibits platelet aggregation and prolongs bleeding time, especially in people who have had coagulation disorders or are taking anticoagulant medicines.
  • Caution should be exercised when using naproxen in patients with bronchial asthma or allergic diseases, as the medicine may contribute to the occurrence of bronchospasm.
  • Severe skin reactions, some of which are fatal, including exfoliative dermatitis, Stevens-Johnson syndrome, toxic epidermal necrolysis, and drug reaction with eosinophilia and systemic symptoms (DRESS syndrome), have been reported in association with the use of NSAIDs. The greatest risk of these severe reactions occurs at the beginning of treatment, in most cases within the first month of using the medicine. You should stop using the medicine after the first symptoms of skin rash, mucosal damage, other symptoms of hypersensitivity or DRESS syndrome.
  • Due to its anti-inflammatory and antipyretic effects, naproxen may mask the symptoms of another disease, making its diagnosis difficult.

Patient with heart failure
Naproxen should be administered with caution, using the smallest effective dose, in patients with heart failure (as it may exacerbate peripheral edema).
Patient with renal and (or) hepatic impairment
Naproxen should be administered with caution, using the smallest effective dose, in patients with liver and kidney function disorders.
In alcoholic liver disease and other forms of liver cirrhosis, there is a decrease in naproxen plasma concentration, with a simultaneous increase in the amount of unbound naproxen.
In patients with renal function disorders, serum creatinine concentration and (or) creatinine clearance should be periodically monitored. The medicine is not recommended for patients with creatinine clearance below 20 ml/minute.
Elderly patient
Naproxen should be administered with caution, using the smallest effective dose, in elderly patients, due to the increased risk of gastrointestinal complications.
You should talk to your doctor, even if the above warnings concern situations that occurred in the past.

Naproxen 250 H or Naproxen 500 H and other medicines

You should tell your doctor or pharmacist about all medicines you are currently taking or have recently taken, as well as about medicines you plan to take.

  • Before starting to take this medicine, you should talk to your doctor or pharmacist if you are taking any of the following medicines:
  • Acetylsalicylic acid used to prevent blood clots.
  • Concomitant administration of antacids or cholestyramine with naproxen may delay its absorption.
  • Non-steroidal anti-inflammatory drugs may increase the effect of anticoagulant medicines, such as warfarin.
  • Naproxen may inhibit the diuretic effect of furosemide.
  • Naproxen inhibits the excretion of lithium, increasing its plasma concentration.
  • Probenecid increases the plasma concentration of naproxen.
  • Naproxen inhibits the excretion of methotrexate, increasing its toxicity.
  • Concomitant use of naproxen with digitalis glycosides may decrease their renal excretion, leading to increased plasma concentration.
  • Naproxen may weaken the antihypertensive effect of propranolol and other beta-blockers, and increase the risk of renal function impairment associated with the use of acetylcholinesterase inhibitors.
  • Caution should be exercised when administering naproxen and cyclosporine concomitantly due to the increased risk of nephrotoxicity.
  • Naproxen used concomitantly with hydantoin, oral anticoagulants, and sulfonamides enhances their effect.
  • Caution should be exercised when using naproxen concomitantly with corticosteroids due to the increased risk of gastrointestinal bleeding.
  • Non-steroidal anti-inflammatory drugs reduce the effect of mifepristone. Naproxen administration can be started 8 to 12 days after the last dose of mifepristone.
  • Concomitant use of naproxen with fluoroquinolones increases the risk of seizures.
  • It is recommended to discontinue naproxen administration 48 hours before assessing adrenal cortex function, due to the possible falsification of 17-ketosteroid and 5-hydroxyindoleacetic acid urine test results.

Naproxen 250 H or Naproxen 500 H with food and drink

Food intake does not significantly affect the degree of naproxen absorption.

Pregnancy, breastfeeding, and fertility

If the patient is pregnant or breastfeeding, suspects that she may be pregnant or plans to have a child, she should consult a doctor or pharmacist before using this medicine.
Pregnancy
Naproxen 250 H or Naproxen 500 H should not be used if the patient is in the last 3 months of pregnancy, as it may harm the unborn child or cause complications during delivery. It may cause kidney and heart disorders in the unborn child. It may increase the risk of bleeding in the patient and her child and cause prolongation or prolongation of the delivery period. During the first 6 months of pregnancy, the medicine should not be used unless it is absolutely necessary and recommended by a doctor. If treatment is necessary during this period or during attempts to become pregnant, the smallest possible dose should be used for the shortest possible time. From the 20th week of pregnancy, Naproxen 250 H or Naproxen 500 H may cause kidney function disorders in the unborn child if used for more than a few days - this may lead to a decrease in the amount of amniotic fluid surrounding the child (oligohydramnios) or narrowing of the blood vessel (ductus arteriosus) in the child's heart. If treatment is necessary for a period longer than a few days, the doctor may recommend additional monitoring.
Breastfeeding
Naproxen passes into breast milk, so it should not be used during breastfeeding.
Fertility
Naproxen may make it difficult to become pregnant. If the patient plans to become pregnant or is having difficulty becoming pregnant, she should inform her doctor.
