2. Important information before taking Naproxen Genoptim

When not to take Naproxen Genoptim:

• if the patient is hypersensitive to the active substance, other nonsteroidal anti-inflammatory drugs (NSAIDs) or any of the other ingredients of this medicine (listed in section
• 6);
• if the use of acetylsalicylic acid or other nonsteroidal anti-inflammatory drugs has caused allergic symptoms: bronchial asthma, rhinitis, urticaria;

Warnings and precautions

Before starting treatment with Naproxen Genoptim, you should discuss it with your doctor or pharmacist.
Naproxen should be administered with caution, using the smallest effective dose, to patients with heart failure (due to the possibility of increased peripheral edema).
In order to detect possible side effects, patients taking nonsteroidal anti-inflammatory drugs for a long time should be subject to regular medical check-ups.
In people who have a risk factor for cardiac complications – hypertension, hyperlipidemia, peripheral circulation disorders, diabetes, and smokers, naproxen should be used with extreme caution.
Taking naproxen carries the risk of developing ulcers, perforations or bleeding from the gastrointestinal tract. These side effects, which can be fatal, may be preceded by warning signs, but do not have to be. The use of Naproxen Genoptim should be discontinued in case of gastrointestinal bleeding or ulcers. Patients who have had gastrointestinal diseases, and in particular elderly patients, should be informed about the need to report any unusual gastrointestinal symptoms to their doctor, especially bleeding.
This is especially important during the initial treatment period. In such patients, the use of the smallest effective dose of the medicine is recommended.
It is recommended to avoid concomitant use of Naproxen Genoptim and other nonsteroidal anti-inflammatory drugs (including selective COX-2 inhibitors) due to the increased risk of serious side effects.
Concomitant use of Naproxen Genoptim with heparin or warfarin should be carried out under medical supervision. Naproxen inhibits platelet aggregation and prolongs bleeding time. In patients taking anticoagulant drugs (e.g. dicumarol) or in whom coagulation disorders have already occurred, the risk of bleeding increases.
In patients with liver function disorders, such as chronic alcoholic liver disease and other forms of liver cirrhosis, the use of the smallest effective dose is recommended.
In patients with bronchial asthma or other allergic diseases, Naproxen Genoptim increases the risk of bronchospasm.
Naproxen Genoptim should be used with caution in patients with impaired renal function.
In these patients, the doctor will prescribe periodic tests of renal function: monitoring serum creatinine levels and (or) creatinine clearance. In patients with a creatinine clearance of less than 20 ml/minute, the medicine is contraindicated.
Due to its anti-inflammatory and antipyretic effects, the use of the medicine may mask the symptoms of another disease and make diagnosis more difficult.
Due to the increased risk of side effects, long-term NSAID therapy is not recommended in elderly patients. They should take the medicine in the smallest effective dose.
Elderly patients taking nonsteroidal anti-inflammatory drugs for a long time should undergo regular medical check-ups.
Taking nonsteroidal anti-inflammatory drugs carries the risk of serious side effects related to the gastrointestinal system. This risk is independent of the duration of NSAID use. Most side effects occur in the elderly and frail, who are less likely to tolerate ulcers and bleeding in the stomach and intestines.
Very rarely, severe skin reactions (some fatal) such as exfoliative dermatitis, Stevens-Johnson syndrome, toxic epidermal necrolysis, and drug reaction with eosinophilia and systemic symptoms (DRESS syndrome) have been observed in patients taking NSAIDs.
The greatest risk of the above reactions occurs at the beginning of treatment with naproxen, most often in the first month of taking the medicine. After the first symptoms of a rash, oral mucosa damage, or other signs of hypersensitivity appear, the use of Naproxen Genoptim should be discontinued and medical attention should be sought immediately.
Hypersensitivity reactions may occur in people with hypersensitivity to acetylsalicylic acid or other nonsteroidal anti-inflammatory drugs, as well as in patients with angioedema, bronchial asthma, nasal inflammation, and nasal polyps. Hypersensitivity reactions can be fatal.
The use of nonsteroidal anti-inflammatory drugs has rarely led to eye diseases: optic neuritis; papillitis. The causal relationship of this mechanism is not known. In case of eye diseases, ophthalmological examinations are recommended.
During treatment with Naproxen Genoptim, the reduction of steroid doses or their withdrawal should be gradual. Due to the possibility of side effects such as adrenal insufficiency or worsening of arthritis symptoms, the patient should be under medical supervision.
Taking such medicines as Naproxen Genoptim may be associated with a small increased risk of myocardial infarction (heart attack) or stroke. This risk increases with long-term use of high doses of the medicine. Do not use higher doses or 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.

Naproxen Genoptim 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, including acetylsalicylic acid used to prevent blood clots.
Acetylsalicylic acid may increase the renal clearance of naproxen and decrease its serum concentration.
Concomitant administration of antacids or cholestyramine with Naproxen Genoptim may delay its absorption. Naproxen Genoptim may increase the effect of anticoagulant medicines, e.g. warfarin and heparin.
Naproxen Genoptim may inhibit the diuretic effect of furosemide and lithium excretion (decrease in renal clearance of lithium ions), leading to increased lithium levels in the blood.
Probenecid increases the concentration of naproxen in the blood and prolongs its half-life.
Concomitant use of Naproxen Genoptim with digitalis glycosides may inhibit the renal excretion of glycosides, leading to an increase in their blood levels.
Naproxen decreases the excretion of methotrexate in the urine, which may lead to increased methotrexate toxicity.
Naproxen reduces the blood pressure-lowering effect of propranolol and other beta-adrenergic receptor blockers. Naproxen increases the risk of renal function disorders associated with ACE inhibitors.
Concomitant use of Naproxen Genoptim with cyclosporin may increase the concentration of cyclosporin in the serum, which may lead to toxic effects on the kidneys.
Concomitant use of NSAIDs with tacrolimus may also have toxic effects on the kidneys.
Naproxen Genoptim enhances the effect of hydantoin, sulfonamides, and oral anticoagulants by displacing their binding to proteins.
Concomitant use of Naproxen Genoptim with corticosteroids increases the risk of gastrointestinal disorders: gastrointestinal bleeding.
Naproxen Genoptim reduces the effect of mifepristone. Only after 8 to 12 days from the last dose of mifepristone can naproxen treatment be started.
Taking Naproxen Genoptim at the same time as fluoroquinolones increases the risk of seizures.
Taking Naproxen Genoptim within 48 hours before an adrenal function test may lead to false results of 17-ketosteroid and 5-hydroxyindoleacetic acid measurements in urine.
Concomitant use of Naproxen Genoptim with anti-aggregant medicines and non-selective inhibitors of serotonin reuptake may increase the risk of gastrointestinal bleeding.
Zidovudine (a medicine used to treat AIDS and HIV infections) increases the risk of toxic effects on the hematopoietic system.

Pregnancy, breastfeeding, and fertility

If you are pregnant or breastfeeding, think you may be pregnant, or plan to have a child, you should consult your doctor or pharmacist before taking this medicine.
Naproxen Genoptim should not be used during the first and second trimester of pregnancy, except in cases recommended and supervised by a doctor, after careful consideration of the potential benefits to the mother and the fetus. Naproxen Genoptim should not be used during 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 affect the tendency to bleed in the mother and child and cause late or prolonged delivery. Naproxen Genoptim should not be taken during the first 6 months of pregnancy, unless it is absolutely necessary and recommended by a doctor. If treatment is necessary during this period or during attempts to conceive, the smallest dose should be used for the shortest possible time. Naproxen Genoptim taken for more than a few days from the 20th week of pregnancy may cause kidney function disorders in the unborn child, which can lead to low levels of amniotic fluid surrounding the child (oligohydramnios) or narrowing of the arterial duct (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.
Naproxen passes into breast milk, so it should not be used in breastfeeding women.
Naproxen Genoptim may make it difficult to conceive. If you plan to conceive or have difficulty conceiving, you should inform your doctor.

Driving and using machines

While taking Naproxen Genoptim, you should be cautious. Some patients may experience: drowsiness, dizziness, balance disorders, insomnia, fatigue, vision disorders, depression.
If you experience any of the above side effects, you should not drive or operate machinery.

Naproxen Genoptim contains lactose.

If you have been diagnosed with an intolerance to some sugars, you should consult your doctor before taking this medicine.

Naproxen Genoptim contains sodium.

The medicine contains less than 1 mmol (23 mg) of sodium per tablet, which means that the medicine is considered "sodium-free".

3. How to take Naproxen Genoptim

This medicine should always be taken exactly as directed by your doctor or pharmacist. If you are unsure, you should consult your doctor or pharmacist. The doctor will adjust the dose individually for you.

Adults:

Rheumatoid arthritis, osteoarthritis, ankylosing spondylitis
The recommended initial dose is usually 500 mg to 1000 mg per day in two divided doses every 12 hours or in a single dose.
In acute conditions, the dose can be increased (for a short period, under strict medical supervision) from 750 mg to 1000 mg per day (loading dose):

• in patients reporting severe nocturnal pain or morning stiffness;
• in patients in whom naproxen replaced other NSAIDs taken in high doses;
• in osteoarthritis with painful symptoms.

Acute gouty attack
Initially 750 mg, then 500 mg after 8 hours, then 250 mg every 8 hours until the attack subsides.
Acute musculoskeletal disorders and painful menstruation
The initial dose is 500 mg once, then 250 mg every 6 to 8 hours, depending on the needs, with a maximum daily dose of 1250 mg after the first day of administration.

Elderly patients

Similarly, as with other medicines, elderly patients are at increased risk of side effects, including gastrointestinal bleeding. This medicine should be administered in the smallest effective dose for the shortest possible period. The doctor will periodically monitor these patients.

Children:

Juvenile rheumatoid arthritis (children over 5 years old and weighing over 25 kg)
The recommended daily dose is 10 mg/kg body weight per day in 2 divided doses every 12 hours (morning and evening). Naproxen is not recommended for use in children under 16 years of age for indications other than juvenile rheumatoid arthritis.

Patients with renal or hepatic impairment

In patients with renal or hepatic impairment, the use of lower doses of naproxen should be considered. The medicine is contraindicated in patients with a creatinine clearance of less than 30 ml/minute, as accumulation of naproxen metabolites has been observed in patients with severe renal failure or those undergoing dialysis, as well as in patients with severe liver failure.
Naproxen Genoptim should be taken during or after a meal.
Taking the medicine in the smallest effective dose and for the shortest possible period necessary to alleviate symptoms reduces the risk of side effects.
The treatment results will be assessed by the doctor at regular intervals, and if there is no improvement, the use of naproxen should be discontinued.

Overdose of Naproxen Genoptim

Symptoms of overdose: drowsiness, vomiting, heartburn, nausea, abdominal pain, kidney function disorders. If you experience any of the above symptoms, you should immediately contact your doctor.
In case of naproxen overdose, the stomach should be emptied, and then appropriate supportive treatment should be applied. Rapid administration of a sufficient amount of activated carbon reduces the amount of absorbed medicine.
In case of renal failure, hemodialysis may be necessary.

Missed dose of Naproxen Genoptim

You should not take a double dose to make up for a missed dose.
