Warnings and precautions

Consult your doctor or pharmacist before starting to take this medication.

Be cautious in the following situations:

• It is essential to use the smallest dose that relieves-controls the pain and not to take this medication for longer than necessary to control your symptoms,
• If you have had or developed an ulcer, bleeding, or perforation in the stomach or duodenum, which may be manifested by intense or persistent abdominal pain and/or black stools, or even without previous warning symptoms,
• If you have had a stomach or duodenal bleeding or have suffered a perforation of the digestive tract while taking a non-steroidal anti-inflammatory drug,
• This risk is higher when high doses and prolonged treatments are used, in patients with a history of peptic ulcers, and in the elderly. In these cases, your doctor will consider the possibility of associating a stomach-protecting medication,
• If you have or have had stomach problems, as this medication can cause stomach irritation, bleeding, or ulcers. Your doctor will recommend the most suitable dose,
• If you have Crohn's disease or ulcerative colitis, as medications like naproxen sodium can worsen these conditions,
• If you have asthma or allergic disorders (such as rhinitis or nasal polyps), as naproxen sodium can cause breathing difficulties (bronchospasm),
• If you have severe kidney, liver, or heart problems,
• If you are taking medications that alter blood coagulation or increase the risk of ulcers, such as oral anticoagulants or antiplatelet agents like acetylsalicylic acid. You should also discuss the use of other medications that may increase the risk of such bleeding, such as corticosteroids and selective serotonin reuptake inhibitors,
• If you have or suspect you have an infection, as this medication can mask the usual signs and symptoms of infectious processes,
• If you experience stomach pain and/or observe black stools while taking this medication, you should interrupt treatment with naproxen sodium,
• If you experience vision disorders during treatment,
• This medication should be used with caution in patients who have a low-salt diet and a history of digestive problems,
• If you wish to become pregnant, as this medication can affect fertility.

There have been reports of severe skin reactions, including Stevens-Johnson Syndrome (SJS) and toxic epidermal necrolysis (TEN), and drug reaction with eosinophilia and systemic symptoms (DRESS), associated with naproxen sodium. Stop taking this medication and consult your doctor immediately if you observe any symptoms related to severe skin reactions described in section 4.

Cardiovascular precautions

Medications like naproxen sodium may be associated with a moderate increase in the risk of heart attacks ("myocardial infarctions") or strokes. This risk is more likely to occur when high doses and prolonged treatments are used. Do not exceed the recommended dose or duration of treatment.

If you have heart problems, a history of strokes, or think you may be at risk for these conditions (for example, you have high blood pressure, diabetes, high cholesterol, or are a smoker), you should consult your doctor or pharmacist about this treatment.

Additionally, this type of medication can cause fluid retention, especially in patients with heart failure and/or high blood pressure (hypertension).

Taking Naproxen Sodium Kern Pharma with other medications

Tell your doctor or pharmacist that you are taking, have recently taken, or may need to take any other medication.

This is very important, as naproxen sodium can alter the way other medications work. It is essential to inform your doctor or pharmacist if you are taking any of these medications:

• Antacids or cholestyramine, as they may delay the action of naproxen sodium, but do not affect the overall effect,
• Acetylsalicylic acid to prevent blood clots,
• Hydantoins (medications used primarily for epilepsy),
• Sulfonylureas (medications for diabetes),
• Sulfonamides (a type of diuretic medication),
• Methotrexate (an immunosuppressive medication),
• Beta-blockers (antihypertensive medication),
• Furosemide (a medication with a natriuretic effect),
• Lithium. It may cause an increase in lithium plasma concentration,
• Corticosteroids, as naproxen sodium may interfere with adrenal function tests,
• Angiotensin-converting enzyme inhibitors (ACE inhibitors, antihypertensive medication),
• Angiotensin receptor blockers (antihypertensive medications).

It may be necessary for your doctor to adjust the dose of one of the two medications. Consult your doctor if you have any questions about these points.

Taking Naproxen Sodium Kern Pharma with food and beverages

It is recommended to take the tablets during meals or immediately after eating to reduce the possibility of stomach discomfort.

Pregnancy, breastfeeding, and fertility

If you are pregnant or breastfeeding, think you may be pregnant, or plan to become pregnant, consult your doctor or pharmacist before using this medication. The oral forms (e.g., tablets) of this medication can cause serious side effects in the fetus.

This medication should not be administered during pregnancy, childbirth, or breastfeeding.

Do not take naproxen sodium if you are in the last 3 months of pregnancy, as it may harm the fetus or cause problems during delivery. It may cause kidney and heart problems in your fetus. It may affect your and your baby's tendency to bleed and prolong or prolong delivery more than expected. You should not take naproxen sodium during the first 6 months of pregnancy unless it is clearly necessary and as directed by your doctor. If you need treatment during this period or while trying to become pregnant, you should take the minimum dose for the shortest possible time. From the 20th week of pregnancy, naproxen sodium may cause kidney problems in your fetus if taken for more than a few days, which can lead to low levels of amniotic fluid surrounding the baby (oligohydramnios) or narrowing of a blood vessel (ductus arteriosus) in the baby's heart. If you need treatment for more than a few days, your doctor may recommend additional monitoring.

For women of childbearing age, it should be noted that medications like naproxen sodium have been associated with decreased fertility.

Driving and using machines

This medication should be used with caution in patients whose activities require attention and who have observed dizziness or visual disturbances during treatment with this medication.
