1. What is Pirexin and what is it used for

Pirexin belongs to a group of medicines called non-steroidal anti-inflammatory drugs (NSAIDs).

This medicine is used for the symptomatic treatment of fever and pain of mild to moderate intensity.

2. What you need to know before you take Pirexin

Do not take Pirexin

• If you are allergic (hypersensitive) to ibuprofen, to other medicines of the NSAID group (e.g. acetylsalicylic acid, naproxen, etc.) or to any of the other ingredients of Pirexin. Such reactions may be: skin rash with itching, swelling of the face, lips or tongue, nasal discharge, difficulty breathing or asthma.
• If you have had a stomach or duodenal ulcer or have suffered a perforation of the digestive tract.
• If you vomit blood.
• If you have black stools or diarrhea with blood.
• If you have a severe liver or kidney disease.
• If you have bleeding disorders or blood coagulation disorders or are taking anticoagulants (medicines used to "thin" the blood). If it is necessary to use anticoagulant medications at the same time, your doctor will perform blood coagulation tests.
• If you have severe heart failure.
• If you are in the third trimester of pregnancy.

Warnings and Precautions

Consult your doctor or pharmacist before starting to take Pirexin. Special caution is recommended with Pirexin.

Tell your doctor:

• 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. This risk is higher when using high doses and prolonged treatments, in patients with a history of peptic ulcer and in elderly patients. In these cases, your doctor will consider the possibility of associating a stomach protective medication.
• If you have edema (fluid retention).
• If you have asthma or any other respiratory disorder.
• If you have had any heart disorder or have high blood pressure.
• If you have kidney or liver disease, are over 60 years old, or need to take the medication for a prolonged period (more than 1 to 2 weeks), your doctor may need to perform regular checks. Your doctor will indicate the frequency of these checks.
• If you experience symptoms of dehydration, e.g. severe diarrhea or vomiting, take plenty of fluids and contact your doctor immediately, as ibuprofen could cause kidney failure as a consequence of dehydration.
• If you are taking medications that alter blood coagulation, such as oral anticoagulants, antiplatelet agents of the type of 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 Crohn's disease or ulcerative colitis, as medications of the Pirexin type may worsen these conditions.
• If you are being treated with diuretics (medications to increase urine production), as your doctor should monitor your kidney function.
• If you have systemic lupus erythematosus (a chronic disease that affects the immune system and can affect various vital organs, the nervous system, blood vessels, skin, and joints), as it may cause aseptic meningitis.
• If you have acute intermittent porphyria (a metabolic disease that affects your blood and can cause symptoms such as reddish urine color, blood in urine, or liver disease), so that your doctor can assess the convenience or not of treatment with ibuprofen.
• If you have an infection; see the "Infections" section below.

• If you experience headaches after prolonged treatment, do not take higher doses of the medication.
• Your doctor will perform stricter monitoring if you receive ibuprofen after undergoing major surgery.
• It is advisable not to take this medication if you have chickenpox.
• It is important to use the smallest dose that relieves/controls the pain and not to take this medication for longer than necessary to control your symptoms.

Allergic Reactions

With ibuprofen, signs of allergic reaction to this medication have been reported, such as respiratory problems, swelling of the face and neck area (angioedema), and chest pain. Stop using Pirexin immediately and contact your doctor or the emergency medical service immediately if you notice any of these signs.

Cardiovascular Precautions

Anti-inflammatory/analgesic medications like ibuprofen may be associated with a small increased risk of suffering a heart attack or stroke, especially when used in high doses. Do not exceed the recommended dose or treatment duration.

You should discuss your treatment with your doctor or pharmacist before taking Pirexin if:

• You have heart problems, including heart failure, angina (chest pain), or if you have had a heart attack, bypass surgery, peripheral arteriopathy (circulation problems in the legs or feet due to narrowing or blockage of the arteries), or any type of stroke (including a "mini-stroke" or transient ischemic attack "TIA").
• You have high blood pressure, diabetes, high cholesterol, have a family history of heart disease or stroke, or are a smoker.

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

Infections

Pirexin may hide the signs of an infection, such as fever and pain. Consequently, Pirexin may delay the appropriate treatment of the infection, which may increase the risk of complications. This has been observed in bacterial pneumonia and bacterial skin infections related to chickenpox. If you take this medication while having an infection and the symptoms of the infection persist or worsen, consult a doctor without delay.

Skin Reactions

Severe skin reactions, such as exfoliative dermatitis, erythema multiforme, Stevens-Johnson syndrome, toxic epidermal necrolysis, drug reaction with eosinophilia and systemic symptoms (DRESS), and acute generalized exanthematous pustulosis (AGEP), have been reported in association with ibuprofen treatment. Discontinue Pirexin treatment and seek medical attention immediately if you notice any of the symptoms related to these severe skin reactions described in section 4.

Precautions during Pregnancy and in Women of Childbearing Age

Because the administration of medications of the Pirexin type has been associated with an increased risk of congenital anomalies/abortions, it is not recommended to administer it during the first and second trimester of pregnancy unless it is considered strictly necessary. In these cases, the dose and duration will be limited to the minimum possible.

In the third trimester, the administration of Pirexin is contraindicated.

For women of childbearing age, it should be taken into account that medications of the Pirexin type have been associated with a decrease in fertility.

Using Pirexin with other Medications

Tell your doctor or pharmacist if you are using or have recently used any other medication, even those purchased without a prescription.

Pirexin may affect or be affected by other medications. For example:

• Anticoagulant medications (e.g. to treat coagulation problems/prevent coagulation, e.g. acetylsalicylic acid, warfarin, ticlopidine).
• Antiplatelet agents (prevent the formation of blood clots or thrombi in blood vessels) such as ticlopidine.
• Corticosteroids such as cortisone and prednisolone.
• Selective serotonin reuptake inhibitors (used in depression).
• Other NSAIDs such as aspirin.
• Lithium (medication used to treat depression). Your doctor may adjust the dose of this medication.
• Methotrexate (for cancer and inflammatory diseases). Your doctor may adjust the dose of this medication.
• Mifepristone (abortion inducer).
• Digoxin and cardiac glycosides (used in the treatment of heart disorders).
• Hydantoins such as phenytoin (used in the treatment of epilepsy).
• Sulfonamides such as sulfamethoxazole and cotrimoxazole (used in the treatment of certain bacterial infections).
• Diuretics (medications used to increase urine production).
• Pentoxifylline (for intermittent claudication).
• Probenecid (used in patients with gout or with penicillin in infections).
• Quinolone antibiotics such as norfloxacin.
• Sulfinpyrazone (for gout).
• Sulfonylureas such as tolbutamide (for diabetes).
• Tacrolimus or cyclosporin (used in organ transplants to prevent rejection).
• Medications that lower high blood pressure (ACE inhibitors such as captopril, beta-blockers such as atenolol, and angiotensin-II receptor antagonists such as losartan).
• Thrombolytics (medications that dissolve blood clots).
• Zidovudine (medication against the AIDS virus).
• Aminoglycoside antibiotics such as neomycin.
• Ginkgo biloba tree extracts.

Other medications may also affect or be affected by Pirexin treatment. Therefore, you should always consult your doctor or pharmacist before using Pirexin with other medications.

Interference with Laboratory Tests

Taking ibuprofen may alter the following laboratory tests:

• Bleeding time (may be prolonged for 1 day after discontinuing treatment).
• Blood glucose concentration (may decrease).
• Creatinine clearance (may decrease).
• Hematocrit or hemoglobin (may decrease).
• Blood concentrations of urea nitrogen and serum creatinine and potassium (may increase).
• Liver function tests: increased transaminase values.

Tell your doctor if you are going to undergo a clinical analysis and are taking or have recently taken ibuprofen.

Taking Pirexin with Food and Drinks

It is recommended to take Pirexin with milk or with food, or immediately after eating, to reduce the possibility of stomach upset.

Pregnancy, Breastfeeding, and Fertility

If you are pregnant or breastfeeding, think you may be pregnant, or are planning to have a baby, ask your doctor or pharmacist for advice before taking this medicine.

Do not take Pirexin during pregnancy, especially during the third trimester (see section precautions during pregnancy and in women of childbearing age).

Although only small amounts of the medication pass into breast milk, it is recommended not to take ibuprofen for prolonged periods during breastfeeding. It is not necessary to interrupt breastfeeding during short-term treatment with the recommended dose for pain and fever.

Driving and Using Machines

If you only take one dose of Pirexin or take it for a short period, it is not necessary to take special precautions.

If you experience dizziness, vertigo, vision disturbances, or other symptoms while taking this medication, do not drive or use hazardous machinery.

Pirexin contains azorubine (E-122), liquid maltitol (E-965), sodium benzoate (E-211), and sodium (as sodium benzoate, sodium citrate, sodium chloride, and sodium saccharin).

This medication:

Contains azorubine (E-122) which may cause allergic reactions. It can cause asthma, especially in patients allergic to acetylsalicylic acid.

Contains liquid maltitol (E-965). If your doctor has told you that you have an intolerance to some sugars, consult with them before taking this medication. It may have a slight laxative effect because it contains 2.5 g of liquid maltitol (E-965) per 5 ml dose. Caloric value: 2.3 kcal/g of maltitol.

Contains 1 mg of sodium benzoate (E-211) per ml. Sodium benzoate may increase the risk of jaundice (yellowing of the skin and eyes) in newborns (up to 4 weeks of age).

Contains less than 23 mg of sodium (1 mmol) per ml; this is, essentially "sodium-free".

3. How to take Pirexin

Follow the administration instructions for this medication exactly as indicated by your doctor. In case of doubt, consult your doctor or pharmacist again.

Pirexin is an oral suspension. It can be administered directly or diluted in water.

For exact dosing, the packages contain a 5 ml oral syringe. The syringe is inserted into the perforated cap, the bottle is inverted, the plunger is pulled until the liquid reaches the corresponding milliliter (ml) mark, the bottle is returned to its initial position, and the syringe is removed.

The syringe should be cleaned and dried after each use.

Patients with stomach discomfort should take the medication with milk or during/after meals.

Children:

The dose of ibuprofen to be administered depends on the child's age and weight. As a general rule, the recommended daily dose is 20 to 30 mg per kg of weight, divided into three or four individual doses. It is recommended not to exceed the maximum daily dose of 40 mg per kg of weight of ibuprofen.

The use of this medication is not recommended in children under 3 months.

The interval between doses will depend on the evolution of symptoms, but it will never be less than 4 hours.

However, as a guideline, the following posology is recommended:

Adults and adolescents (over 12 years):

Due to the amount of ibuprofen contained in this medication, it is recommended to use other more suitable presentations for the treatment of adults and adolescents over 12 years.

Patients with kidney and/or liver disease:

If you have kidney and/or liver disease, your doctor may prescribe a lower dose than usual. If so, take the exact dose that your doctor has prescribed.

Elderly patients:

If you are over 60 years old, your doctor may prescribe a lower dose than usual. If so, you can only increase the dose once your doctor has checked that you tolerate the medication well.

The effective lowest dose should be used for the shortest necessary time to relieve symptoms. If you have an infection, consult your doctor without delay if symptoms (such as fever and pain) persist or worsen (see section 2).

If you think the action of this medication is too strong or too weak, inform your doctor or pharmacist.

If you take more Pirexin than you should

If you have taken more Pirexin than you should, or if a child has accidentally ingested the medication, consult your doctor or go to the nearest hospital immediately to find out about the risk and ask for advice on the measures to be taken.

Overdose symptoms may include nausea, stomach pain, vomiting (which may contain bloody sputum), gastrointestinal bleeding (see also section 4), diarrhea, headache, ringing in the ears, confusion, and involuntary eye movement. Agitation, drowsiness, disorientation, or coma may also occur. Occasionally, patients develop seizures. At high doses, symptoms of numbness, chest pain, palpitations, loss of consciousness, seizures (mainly in children), weakness, and dizziness, blood in the urine, low potassium levels in the blood, chills, and breathing problems have been reported. Additionally, the prothrombin time with INR may be prolonged, probably due to interference with the actions of circulating coagulation factors. Acute kidney failure and liver damage may occur. Exacerbation of asthma is possible in asthmatics. There may also be low blood pressure and reduced breathing.

If a severe poisoning has occurred, the doctor will take the necessary measures.

In case of ingestion of significant amounts, activated charcoal should be administered. Stomach emptying will be considered if significant amounts have been ingested and within 60 minutes after ingestion.

If you forget to take Pirexin

Do not take a double dose to make up for forgotten doses.

If you forget to take your corresponding dose, take it as soon as you remember. However, if the time of the next dose is very close, skip the forgotten dose and take the next dose at its usual time.
