BRONCOVIR ORAL SUSPENSION

2. What you need to know before you take Broncovir suspension

Do not take Broncovir:

• If you are allergic to sulfonamides, trimethoprim, cotrimoxazole, or any of the other components of this medicine (listed in section 6).
• If you have or think you have acute porphyria (a blood disease in which hemoglobin is not produced properly).
• Do not administer to children under 2 years of age.
• If you are pregnant.

Warnings and precautions

Consult your doctor or pharmacist before starting to take Broncovir oral suspension.

• In elderly patients, as they may be more likely to experience severe effects.
• If you have kidney problems (known renal insufficiency). Your doctor should take special measures. To ensure adequate renal elimination, the patient should receive adequate fluid intake and the urinary pH should be maintained within normal limits, avoiding acidification of the urine.
• If you have liver problems.
• If you have severe blood disorders, except in cases where there is close medical supervision.
• If you have a deficiency of an enzyme called glucose-6-phosphate dehydrogenase (G-6-PD).
• If you take Broncovir for a long time or if you have a folate deficiency or are an elderly patient, your doctor may request that you have blood tests to perform blood counts.
• If you are at risk of hyperkalemia (high potassium levels) or hyponatremia (low sodium levels), your doctor will consider the need for potassium and sodium control in the blood.
• If you have phenylketonuria (a metabolic disease that affects the enzyme phenylalanine), as the administration of trimethoprim alters phenylalanine metabolism. This is not a problem in patients with an adequate restrictive diet.
• Broncovir may interfere with the results of some analytical tests.
• If you experience an unexpected worsening of cough and shortness of breath, inform your doctor immediately.

There have been rare cases of death due to severe reactions, including fulminant hepatic necrosis (severe liver damage), agranulocytosis (decrease in the number of a certain type of white blood cell), aplastic anemia (insufficiency of the bone marrow to produce different types of cells), and other blood disorders, as well as respiratory hypersensitivity.

There have been reports of skin eruptions that can be life-threatening (Stevens-Johnson syndrome and toxic epidermal necrolysis) with the use of Broncovir, initially appearing as red spots or patches, often with a central blister.

Other additional signs that may appear are sores in the mouth, throat, nose, genitals, and conjunctivitis (swollen and red eyes).

These life-threatening skin eruptions are often accompanied by flu-like symptoms. The rash can progress to generalized blistering or peeling of the skin.

The period of highest risk 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 Broncovir, you should not use Broncovir again at any time.

If you develop a rash or these skin symptoms, stop taking Broncovir, go to a doctor immediately, and inform them that you are taking this medicine.

Hemophagocytic lymphohistiocytosis

Very rare cases of excessive immune reactions have been reported due to unregulated activation of white blood cells, causing inflammation (hemophagocytic lymphohistiocytosis), which can be potentially fatal if not diagnosed and treated early. If you experience multiple symptoms such as fever, swelling of the lymph nodes, feeling of weakness, dizziness, shortness of breath, bruising, or skin rash, either simultaneously or with a slight delay, contact your doctor immediately.

Taking Broncovir oral suspension with food and drinks:

Broncovir can be taken with or without food.

To ensure adequate renal elimination, the patient should receive adequate fluid intake and the urinary pH should be maintained within normal limits, avoiding acidification of the urine.

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 medicine.

Trimethoprim and sulfamethoxazole cross the placenta, and their safety in pregnant women has not been established. Trimethoprim/sulfamethoxazole should be avoided in pregnancy, unless the potential benefit to the mother outweighs the potential risk to the fetus, and a folate supplement may be considered if trimethoprim/sulfamethoxazole is used during pregnancy.

When Broncovir is administered to the mother before birth, there may be a theoretical risk of kernicterus (severe neurological complication due to increased bilirubin in the blood) in the newborn. This theoretical risk is particularly important in children with a higher risk of hyperbilirubinemia, such as premature infants or those with glucose-6-phosphate dehydrogenase deficiency.

The administration of trimethoprim/sulfamethoxazole should be avoided in the final stage of pregnancy and in breastfeeding mothers, when the mothers or children have or are at particular risk of developing hyperbilirubinemia, are premature, or have glucose-6-phosphate dehydrogenase deficiency (G-6-PD).

The medicine is excreted in breast milk.

Driving and using machines:

The influence of Broncovir on the ability to drive and use machines is negligible or insignificant.

However, if you notice any symptoms, do not drive or use machines until you know how you tolerate the medicine.

Broncovir oral suspension contains sucrose

This medicine contains 3g of sucrose per 7.5ml, which should be taken into account in patients with hereditary fructose intolerance, glucose/galactose malabsorption, sucrose-isomaltase deficiency, and diabetic patients.

This medicine may cause severe allergic reactions and bronchospasm (sudden feeling of suffocation) because it contains ammonium sulfate.

Use of other medicines:

Tell your doctor or pharmacist if you are taking, have recently taken, or might take any other medicines.

Broncovir may enhance the effect and/or toxicity of some medicines. It is essential that you inform your doctor if you are taking or have recently taken any of the following medicines:

• Medicines used to increase urine elimination: diuretics (especially thiazides). The concomitant administration of diuretics with trimethoprim/sulfamethoxazole in elderly patients may have a higher risk of thrombocytopenia (decrease in platelet count) and hyponatremia (low sodium levels).
• Medicines that are antagonists of folic acid, such as phenytoin (used to treat epilepsy) and methotrexate (used to treat various types of cancer and also to treat rheumatoid arthritis). If trimethoprim/sulfamethoxazole and phenytoin are administered, the excessive effect of phenytoin should be taken into account. If Broncovir is administered with methotrexate, the administration of a folate supplement should be considered.
• Medicines for treating diabetes or for making blood more fluid (anticoagulants). If a variation in response to usual doses of anticoagulant or antidiabetic is observed, the doctor will adjust the dose during the period of concomitant administration with Broncovir.

3. How to take Broncovir

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

Remember to take your medicine.

Your doctor will indicate the duration of your treatment with Broncovir. Do not stop treatment before.

Pneumocystis jiroveci (P. carinii) pneumonia

Adults, adolescents, and children:

20mg of trimethoprim and 100mg of sulfamethoxazole/kg/day in two or more doses for two weeks.

The daily dose administered in one day of treatment is approximately 150mg of trimethoprim/day and 750mg of sulfamethoxazole/day. The total daily dose should not exceed 320mg of trimethoprim and 1600mg of sulfamethoxazole (30ml).

Acute exacerbations of chronic bronchitis in patients without risk factors, acute otitis media, and acute bacterial sinusitis:

• Adults and adolescents (12 to 18 years):

15ml of Broncovir oral suspension every 12 hours (160mg of trimethoprim/800mg of sulfamethoxazole/12 hours)

• Children (2-11 years):

3.75ml of Broncovir oral suspension every 12 hours (40mg of trimethoprim/200mg of sulfamethoxazole/12 hours)

Special populations

Elderly patients:

Available data do not indicate that the dose should be adjusted in this population; therefore, the standard dose will be used.

Patients with renal insufficiency:

Adults and adolescents (12 to 18 years)

It is recommended to measure the plasma concentration of sulfamethoxazole at intervals of 2-3 days in samples obtained 12 hours after the administration of Broncovir. If the total sulfamethoxazole concentration exceeds 150 micrograms/ml, treatment should be interrupted until the value is below 120 micrograms/ml.

No information is available for children under 12 years of age.

If you take more Broncovir than you should:

Symptoms of overdose include vomiting, visual and mental disturbances, yellowing of the skin (jaundice), skin lesions (purpura and petechiae).

In acute overdose with trimethoprim, bone marrow depression has been observed.

If vomiting does not occur, it should be induced. Gastric lavage should be performed. Depending on the state of renal function, administration of fluids is recommended if urinary elimination is low.

In case of overdose or accidental ingestion, consult the Toxicology Information Service. Phone: 91 562 04 20, indicating the medicine and the amount taken.

If you forget to take Broncovir:

Do not take a double dose to make up for forgotten doses, wait for the next dose and continue taking Broncovir as usual.
