Sulfamethoxazole + Trimethoprim
Biseptol is an antibacterial medicine, containing cotrimoxazole, which consists of two active substances: sulfamethoxazole (a sulfonamide with a medium duration of action) and trimethoprim, in appropriate proportions. Both components of the medicine act on the same biochemical process, which leads to an increase in antibacterial activity and slower development of bacterial resistance. Before recommending the use of the medicine, the doctor will consider the sensitivity of the microorganisms causing the infection and the possibility of side effects. The therapeutic indications are limited to infections caused by microorganisms sensitive to this medicine. Biseptol should be used for the treatment or prevention of infections, only in cases where it has been confirmed or there is a justified suspicion that they were caused by bacteria or other microorganisms sensitive to the active substances of this medicine. Both components of the medicine are quickly absorbed from the gastrointestinal tract; the maximum concentration of both components in the blood occurs 1-4 hours after oral administration. Both compounds appear in therapeutic concentrations in many tissues and body fluids. Biseptol is indicated for the treatment of adults, adolescents, and children over 6 years of age.
The medicine is used to treat the following bacterial infections:
The following situations are described in which you should be particularly careful when taking Biseptol.
If you experience an increase in cough and shortness of breath, you should tell your doctor immediately. The risk of severe side effects is higher:
During treatment with Biseptol, potentially life-threatening skin rashes (Stevens-Johnson syndrome, toxic epidermal necrolysis) have been reported, which can start on the torso as red, blistering spots or circular patches, often with localized blisters. Additional symptoms may include oral, pharyngeal, and genital ulcers, as well as eye inflammation (red and swollen eyes). Potentially life-threatening skin rashes are often accompanied by flu-like symptoms. The rash can spread to large blisters or may lead to skin peeling. The greatest risk of severe skin reactions occurs within the first few weeks of treatment. If you have experienced Stevens-Johnson syndrome or toxic epidermal necrolysis while taking Biseptol, you should never take Biseptol again. If you experience a rash or skin symptoms, you should contact your doctor immediately and inform them that you are taking Biseptol. Hemophagocytic lymphohistiocytosis Very rare cases of severe immune reactions resulting from uncontrolled activation of white blood cells, leading to inflammatory conditions (hemophagocytic lymphohistiocytosis) have been reported - these can be life-threatening if not diagnosed and treated early. If multiple symptoms occur simultaneously or with a slight delay, such as fever, lymph node swelling, weakness, dizziness, shortness of breath, cyanosis, or skin rash, you should contact your doctor immediately.
Sulfonamides, including Biseptol, may cause increased urine excretion, especially in patients with heart failure. The doctor should carefully monitor serum potassium levels and kidney function in patients: taking high doses of Biseptol, used in patients with pneumonia caused by Pneumocystis jiroveciitaking the usual recommended dose of Biseptol, who have potassium metabolism disorders or renal impairment who are taking medicines that increase potassium levels in the blood (see "Biseptol and other medicines" below).
During long-term treatment with Biseptol, the doctor will recommend regular blood, urine, and kidney function tests. You should drink plenty of fluids during treatment. If you have a folic acid deficiency, you may experience blood-related side effects. These symptoms disappear after folic acid administration. Biseptol should not be used in patients with G6PD enzyme deficiency, except in cases of absolute necessity. In such cases, only minimal doses of the medicine should be used.
In patients with renal impairment, the doctor will recommend a dose adjusted for the individual patient based on the results of tests (creatinine clearance), see section 3.
The medicine should be used with caution. The doctor will order more frequent blood tests.
The medicine should be used with caution due to the increased risk of severe side effects - see section 3.
In patients with folic acid deficiency (in elderly people, patients with pre-existing folic acid deficiency, or patients with renal impairment), blood-related side effects occur more frequently. These symptoms disappear after folic acid administration. The doctor will order periodic blood tests.
Children under 6 years of age: tablets are not recommended due to the risk of choking; for younger children, under 6 years of age, suspensions are available. In infants under 2 months of age, Biseptol is contraindicated.
You should tell your doctor about all medicines you are currently taking or have recently taken, as well as any medicines you plan to take. The doctor will decide on continuation, possible modification, and monitoring of treatment effects. This applies in particular to medicines containing:
It is not recommended to take Biseptol concurrently with medicines containing:
Effect on laboratory tests:
The medicine should be taken orally during meals or immediately after meals. During treatment, you should drink plenty of fluids.
If you are pregnant or breastfeeding, think you may be pregnant, or plan to have a child, you should consult your doctor or pharmacist before taking this medicine. Pregnancy: The doctor will consider the use of Biseptol in pregnant or breastfeeding women. There is no clear evidence of the risk of fetal developmental abnormalities in women treated with cotrimoxazole in early pregnancy. However, an increased risk of spontaneous abortion has been observed in women who took trimethoprim or trimethoprim in combination with sulfamethoxazole in the first trimester of pregnancy. Animal studies indicate that very high doses of cotrimoxazole can cause fetal developmental abnormalities typical of folic acid-lowering substances. The medicine may be used during pregnancy only if, in the doctor's opinion, the expected benefits of treatment outweigh the potential risk to the fetus. In such cases, pregnant women or women planning to become pregnant during treatment with Biseptol are advised to take folic acid at a dose of 5 mg per day. Whenever possible, Biseptol should be avoided in the last period of pregnancy due to the risk of kernicterus in the newborn. Breastfeeding: Both trimethoprim and sulfamethoxazole pass into breast milk, so the doctor must consider the risk to the child (kernicterus, hypersensitivity) in relation to the expected therapeutic benefits for the mother. Cotrimoxazole is not recommended during breastfeeding. Fertility: There is no available data on the effect on fertility.
There is no data on the effect of the medicine on the ability to drive and use machines. Biseptol 960 contains sodium. The medicine contains less than 1 mmol (23 mg) of sodium per tablet, which means the medicine is considered "sodium-free".
