Tenoxicam is a medication that belongs to the group of medications called nonsteroidal anti-inflammatory drugs (NSAIDs), which acts by reducing inflammation.

Reutenox is indicated for:

• Treatment of painful inflammatory conditions of muscles, joints, tendons, and ligaments.
• Treatment of menstrual pain.

Reutenox has a strong and lasting effect on pain and inflammation or swelling. It does not eliminate the causes of muscle and joint conditions, but it improves symptoms.

It is essential to use the smallest dose that relieves or controls pain and not to take this medicationReutenox 20 mg for longer than necessary to control symptoms.

Do not take Reutenox:

• If you are allergic to tenoxicam or any of the other components of this medication (including those listed in section 6), or to any anti-inflammatory or calming medication.
• If you react with asthma, rhinitis, or skin alterations when taking medications containing salicylates as the active ingredient, or other non-steroidal anti-inflammatory drugs.
• If you have severe renal or hepatic insufficiency.
• If you are allergic to dairy products, as Reutenox contains powdered cow's milk. If you are unsure, consult your doctor.
• If you have had a stomach or duodenal ulcer or hemorrhage or have suffered a perforation of the digestive apparatus.
• If you have severe heart failure.
• If you are in the third trimester of pregnancy.

Warnings and precautions:

• If you have had or develop a stomach or duodenal ulcer, hemorrhage, or perforation, which may manifest as intense or persistent abdominal pain and/or black stools, or even without previous warning symptoms.
• This risk is higher when using high doses and prolonged treatments, 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 protector medication.
• Inform your doctor

• If you have renal or hepatic dysfunction.
• If you have blood disorders.
• If you have heart diseases or other diseases.
• If you have allergies.
• If you are to be operated on and are taking Reutenox, as your doctor will decide on the treatment.
• If you are taking medications that alter blood coagulation, such as corticosteroids, oral anticoagulants, or antiplatelet agents of the type of acetylsalicylic acid. You should also inform your doctor about the use of other medications that may increase the risk of these hemorrhages, such as corticosteroids and selective serotonin reuptake inhibitors.
• If you have Crohn's disease or ulcerative colitis, as Reutenox-type medications may worsen these pathologies.

Cardiovascular Precautions

Medications such as Reutenox 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 treatments. 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, suffer from diabetes, have high cholesterol, or are a smoker), consult this treatment with your doctor or pharmacist.

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

Severe skin eruptions that can threaten the patient's life (Stevens-Johnson syndrome and toxic epidermal necrolysis) have been described with the use of Reutenox, initially appearing as red, circular spots with a central blister.

Additional signs that may appear include mouth, throat, nose, genital, and conjunctivitis (swollen and red eyes) lesions.

These life-threatening skin eruptions often accompany flu-like symptoms. The rash may progress to widespread blistering or skin peeling.

The highest risk period for the appearance of severe skin reactions is during the first weeks of treatment.

If you have developed Stevens-Johnson syndrome or toxic epidermal necrolysis with the use of Reutenox, do not use Reutenox again at any time.

If you develop rashes or these skin symptoms, seek immediate medical attention and inform your doctor that you are taking this medication.

Reutenox Interactions with Other Medications

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 taking multiple medications at the same time may increase or decrease their effect. For example, other medications used to treat muscle or joint pain (salicylates or other non-steroidal anti-inflammatory drugs) may increase the frequency of gastrointestinal side effects (stomach disorders).

Caution should be exercised when taking Reutenox with other medications containing methotrexate as the active ingredient, as severe adverse effects may occur, such as blood disorders, liver or kidney problems, diarrhea, or inflammation and ulceration of the mouth.

The combination of Reutenox and lithium may cause undesirable effects such as tremors, vomiting, skin redness, and fluid retention. However, no clinically relevant interactions have been detected between Reutenox and low-molecular-weight heparin.

You should consult your doctor if you are taking medications containing the following active ingredients: salicylates, other non-steroidal anti-inflammatory drugs, diuretics that conserve potassium (substances that increase urine flow), alpha-adrenergic blockers, hydrochlorothiazide, and inhibitors of the ECA (substances that lower blood pressure), anticoagulants (substances that thin the blood), antidiabetic medications (substances that lower blood sugar levels), or corticosteroids (substances used to treat, for example, allergic reactions such as asthma or skin alterations).

Consult with your doctor if you need more information about this.

In any case, the daily dose will not exceed 2 packets, corresponding to 40 mg of tenoxicam.

Reutenox provides relief shortly after starting treatment, and this relief may increase over time. In prolonged treatments, your doctor may prescribe lower daily doses to maintain the same effect.

Patients of advanced age

Your doctor will decide on the dose, which will generally be lower than that prescribed for other adult patients. While taking Reutenox, your doctor will ask you to attend a consultation to check that the dose is correct for you and to determine if any adverse effects occur. This is especially important if you are an elderly person. Risks are more likely with high doses and prolonged treatments. Do not exceed the recommended dose or treatment duration.

If the patient has liver, kidney, heart, blood, or stomach problems, your doctor will decide whether it is appropriate to administerReutenox at lower doses or if the patient should not take it. Follow your doctor's instructions carefully.

Do not change the dose prescribed by your doctor. If you consider that the medication's effect is too weak or too strong, you must consult your doctor.

Do not interrupt treatment on your own, as your doctor is the one who should decide on the treatment duration. If your doctor considers it necessary, treatment withReutenox may be restarted later.

Reutenox is prescribed individually by your doctor for each patient, and under no circumstances should you give it to a third party.
