Warnings and precautions

Consult your doctor or pharmacist before starting to take naproxen:

Severe skin reactions have been reported with the use of nonsteroidal anti-inflammatory drugs, appearing as red patches, generalized skin redness, ulcers, or widespread rash accompanied by symptoms similar to the flu, including fever (see section 4). The rash may progress to generalized blisters or skin peeling. The highest risk of these severe skin reactions is during the first weeks of treatment, but they may start to develop several months after administration of the medication (see section 4). If you have developed any of these severe skin reactions with the use of Naproxeno, do not restart treatment with this medication at any time. If you develop a skin rash or these symptoms, stop taking Naproxeno and contact your doctor or seek immediate medical attention.

Severe skin reactions, including Stevens-Johnson syndrome (SJS), toxic epidermal necrolysis (Lyell syndrome), and drug reaction with eosinophilia and systemic symptoms (DRESS), have been reported in association with naproxen. Stop taking this medication and consult your doctor immediately if you observe any symptoms related to severe skin reactions described in section 4.

During treatment with naproxen, kidney inflammation may occur. Signs and symptoms may include decreased urine volume or blood in the urine and/or hypersensitivity reactions such as fever, skin rash, and joint stiffness. Inform your doctor of these signs.

Be cautious in the following situations:

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

Cardiovascular precautions

Medications like naproxen may be associated with a moderate increase in the risk of suffering heart attacks ("myocardial infarctions") or strokes. This risk is more likely to occur when using high doses and prolonged treatment. 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 (e.g., you have high blood pressure, diabetes, high cholesterol, or are a smoker), consult this treatment with your doctor or pharmacist.

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

Other medications and Naproxeno sódico Normon

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

This is very important, as naproxen may alter the way other medications work. It is essential to inform your doctor if you take any of the following medications:

• Antacids or cholestyramine, as they may delay the action of Naproxeno, but do not affect the total effect.
• Acetylsalicylic acid to prevent blood clots.
• Hydantoins (medications used primarily for epilepsy).
• Sulfonilureas (diabetes medications).
• Sulfonamides (a type of diuretic medication).
• Metotrexate (an immunosuppressive medication).
• Beta-blockers (anti-hypertensive medication).
• Furosemide (a medication with natriuretic effect).
• Lithium. It may cause an increase in lithium plasma concentration.
• Glucocorticoids, Naproxeno may interfere with adrenal function tests.
• ACE inhibitors (anti-hypertensive medication).
• Angiotensin receptor antagonists (anti-hypertensive medication).

You may need your doctor to adjust the dose of one of the medications. Consult your doctor if you have any doubts about these points..

Taking Naproxeno sódico Normon with food and drinks

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 intend to become pregnant, consult your doctor or pharmacist before using this medication.

Naproxeno sódico Normon should not be administered during pregnancy, childbirth, or breastfeeding.

Do not take Naproxeno 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 predisposition and that of your baby to bleed and delay or prolong delivery more than expected.

Due to the association of naproxen-type medications with an increased risk of congenital anomalies/abortions, do not take naproxen during the first and second trimesters of pregnancy unless strictly necessary and your doctor indicates it. 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 week 20 of pregnancy, naproxen may cause kidney problems in your fetus if taken for more than a few days, which may lead to low amniotic fluid levels surrounding the baby. If you need treatment for more than a few days, your doctor may recommend additional monitoring.

For fertile women, it is essential to consider that naproxen-type medications have been associated with a decrease in the ability to conceive.
