• in patients with severe liver failure, severe kidney failure, or severe heart failure,
• in patients with active or past peptic ulcer disease and (or) duodenal ulcer, perforation, or bleeding, also occurring after the use of NSAIDs,
• during the third trimester of pregnancy,
• in patients with bleeding disorders.

Warnings and precautions

Before starting Naproxen Hasco, you should discuss it with your doctor, pharmacist, or nurse.

• Taking the medicine in the smallest effective dose and for the shortest possible time necessary to relieve symptoms reduces the risk of side effects. Patients treated with NSAIDs for a long time should undergo regular medical check-ups to detect any potential side effects of treatment.
• Taking such medicines 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 problems, a history of stroke, or suspected risk of these disorders (e.g. high blood pressure, diabetes, increased cholesterol levels, 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, you should stop using naproxen. 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 administration of naproxen and other non-steroidal anti-inflammatory drugs is not recommended due to the increased risk of serious side effects.
• 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 individuals who have previously had coagulation disorders or are taking anticoagulant medications.
• 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), have been reported in association with the use of NSAIDs. The greatest risk of these severe reactions occurs at the beginning of therapy, 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.
• Naproxen, due to its anti-inflammatory and antipyretic effects, may mask the symptoms of another disease, making its diagnosis more difficult.

Patient with heart failure
Naproxen should be used 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 used with caution, using the smallest effective dose, in patients with hepatic and renal impairment.
2/6
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 impairment, 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 patients
Naproxen should be used with caution, using the smallest effective dose, in elderly patients, due to the increased risk of gastrointestinal complications.

Naproxen Hasco and other medicines

Please tell your doctor or pharmacist about all medicines you are currently taking or have recently taken, as well as any 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 medications, 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, as well as increase the risk of renal impairment associated with the use of ACE 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 the use of naproxen 48 hours before assessing adrenal cortex function, due to the potential for falsifying the results.

Pregnancy

If treatment is necessary during this period or during attempts to conceive, you should use the smallest possible dose for the shortest possible time. From the 20th week of pregnancy, Naproxen Hasco may cause kidney problems in the unborn child if taken 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 arterial duct (ductal constriction) in the child's heart. If treatment is necessary for a longer period, your doctor may recommend additional monitoring.
Breastfeeding
Naproxen passes into breast milk, so you should not use it during breastfeeding.
