• If you are allergic (hypersensitive) to naproxen, naproxen sodium, or any of the other components of Naproxen Normon.
• If you have an allergy to acetylsalicylic acid or other non-steroidal anti-inflammatory drugs and/or they cause you severe allergic reactions.
• If you have had a stomach or duodenal hemorrhage or have suffered a perforation of the digestive tract while taking a non-steroidal anti-inflammatory drug.
• If you have any intestinal disease.
• If you have severe liver or kidney disease.
• Naproxen Normon should not be administered to children under 2 years of age.

Be careful with Naproxen Normon:

• If you have had or develop an ulcer, hemorrhage, 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.

This risk is greater when high doses and prolonged treatments are used, in patients with a history of peptic ulcer and in the elderly. In these cases, your doctor will consider the possibility of associating a stomach protective medication.

• If you have asthma or allergic disorders, as Naproxen Normon may cause breathing difficulties (bronchospasm).

If you have severe kidney, liver, or heart problems, consult your doctor.

• Medicines like Naproxen Normon can be associated with a moderate increase in the risk of suffering heart attacks ('myocardial infarction') or strokes. This risk is more likely to occur when high doses and prolonged treatments are used. Do not exceed the recommended dose or treatment duration.

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.

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

• If you are taking other anti-inflammatory drugs, consult your doctor.
• If you have or suspect you have an infection, as Naproxen Normon may mask the usual signs and symptoms of infectious processes, consult your doctor.

• If you experience vision disorders during treatment, consult your doctor or pharmacist.

Tell your doctor:

• If you are taking medications that alter blood coagulation or increase the risk of ulcers, such as oral anticoagulants or antiplatelet agents of the acetylsalicylic acid type. You should also discuss the use of other medications that may increase the risk of such hemorrhages, such as corticosteroids and selective serotonin reuptake inhibitor antidepressants.
• If you have Crohn's disease or ulcerative colitis, as medications of the Naproxen Normon type may worsen these conditions.
• There have been reports of serious skin reactions, including Stevens-Johnson Syndrome (SJS) and toxic epidermal necrolysis (Lyell's syndrome), and drug reaction with eosinophilia and systemic symptoms (DRESS), in association with Naproxen Normon. Stop taking Naproxen Normon and consult your doctor immediately if you observe any of the symptoms related to serious skin reactions described in section 4.

Use of other medications:

Tell your doctor or pharmacist if you are using or have recently used other medications, including those obtained without a prescription.

• antacids or cholestyramine, as they may delay the action of Naproxen Normon,
• hydantoins (medications used preferably for epilepsy),
• sulfonylureas (medications for diabetes),
• sulfonamides (a type of medication used to increase urine elimination),
• methotrexate (an immunosuppressive medication),
• probenecid (a medication used in patients with gout),
• furosemide (a type of medication used to increase urine elimination),
