pharmachologic effect

Biseptol is a combined antibacterial drug with a broad spectrum of bactericidal action, the mechanism of which is due to the blocking of folate biosynthesis in microbial cells.
Sulfamethoxazole disrupts the synthesis of dihydrofolic acid, and trimethoprim prevents the conversion of dihydrofolic acid to tetrahydrofolic acid.
It is active against almost all groups of microorganisms - gram-negative bacteria: Salmonella spp., Shigella spp., Neisseria spp., Proteus vulgaris, Vibrio cholerae, Yersinia spp., Escherichia coli, Corynebacterium spp.; Gram-positive bacteria: Staphylococcus spp. and others.
Chlamydia spp., Actinomyces spp., Klebsiella spp. Are also sensitive to the drug.
The drug is resistant to mycobacteria, viruses, most anaerobic bacteria.

- otitis, sinusitis;
- Meningitis, abscess of the brain;
- infections of the genitourinary system (including pyelonephritis, urethritis, salpingitis, prostatitis);
- gonorrhea;
- gastrointestinal infections (including typhoid fever, paratyphoid fever, bacterial dysentery, cholera, diarrhea).

- violations of the hematopoietic system;
- Severe diseases of the cardiovascular system;
- deficiency of glucose-6-phosphate dehydrogenase;
- pregnancy;
- children's age up to 3 months;

special instructions

Care must be taken when prescribing Biseptol to patients with impaired liver and / or kidney function, with a history of allergic reactions, with folic acid deficiency, and elderly patients.
The appearance of a skin rash or diarrhea severe course is an indication for discontinuation of the drug.
Not indicated the appointment of Biseptol for the treatment of angina caused by streptococcus.
During treatment with Biseptolum, adequate fluid intake should be ensured due to the risk of developing crystalluria and urolithiasis.
When determining the level of creatinine using alkaline picrinate Jaffe while taking Biseptol, it should be taken into account that the result can be 10% higher than the true one.
Control of laboratory parameters
With prolonged use of the drug is necessary to monitor the picture of peripheral blood.

Drug interaction

With the simultaneous use of trimethoprim enhances the action of hypoglycemic agents - sulfonylurea derivatives.
The combined use of Biseptol with thiazide diuretics increases the risk of thrombocytopenia and increased bleeding.
Co-trimoxazole enhances the anticoagulant effect of warfarin and the anticonvulsant activity of phenytoin.
When combined, rifampicin reduces the half-life of trimethoprim.
The combined use of Biseptol and cyclosporine after kidney transplantation worsens the patient's condition.


Symptoms: nausea, vomiting, clouding of consciousness.
