1. What is Debecylina and what is it used for

Benzylopenicillin benzathine is a long-acting penicillin antibiotic.
Indications for use
Benzylopenicillin benzathine is indicated for the treatment of the following infections caused by susceptible microorganisms, when a low but prolonged blood antibiotic concentration is required.
Adults

• upper respiratory tract infections caused by susceptible streptococci;
• venereal diseases - syphilis;
• prevention of recurrences of acute rheumatic fever, endocarditis, and glomerulonephritis. Children
• exclusively for the prevention of rheumatic disease and endocarditis.

Before starting treatment with benzathine penicillin, the doctor should order a sensitivity test of the microorganism causing the infection. Treatment may be initiated before the test results are available. Once the results are available (antibiogram), the doctor may change the antibiotic.
When deciding on treatment, the doctor will take into account the official guidelines for the use of antibacterial agents.

2. Important information before using Debecylina

When not to use Debecylina

If you are allergic to penicillins or any of the other ingredients of this medicine (listed in section 6).
Do not inject into the area of a nerve or blood vessel.

Warnings and precautions

Warning!In cases of acute or severe infections, when high blood concentrations are required, it is recommended to administer benzylpenicillin potassium or sodium intramuscularly or intravenously.
Before starting treatment, tell your doctor:

• if you have ever had an allergic reaction to any antibiotic;
• if you have ever had any other allergic reaction. Allergic reactions to penicillin may occur more frequently in people with a tendency to allergic reactions to many different substances. These reactions can have various symptoms and severity - from skin changes to anaphylactic shock (severe allergic reaction), see section 4.
• if you have kidney disease. Your doctor may adjust the dose of the medicine according to the degree of kidney failure. You should consult your doctor, even if the above warnings refer to past situations.

If you experience any of the following symptoms while using Debecylina, seek medical attention immediately:

• if skin changes (e.g., hives, itching) occur, which may be symptoms of an allergic reaction - see section 4.
• severe and persistent diarrhea, occurring during or after treatment with penicillin - may be a sign of pseudomembranous colitis, a complication associated with antibiotic use; do not take medications that slow down intestinal motility or other constipating medications, just consult your doctor, who will prescribe appropriate treatment.
• new fungal or bacterial infections caused by the overgrowth of non-susceptible strains of bacteria or fungi during penicillin treatment; in this case, discontinue the antibiotic and contact your doctor immediately.
• if you experience fever, general malaise, headache. These may be symptoms of a Jarisch-Herxheimer reaction. This reaction may occur during the treatment of early syphilis - see section 4.

During long-term treatment with benzathine penicillin, especially if high doses are used, your doctor will recommend periodic monitoring of kidney function and the hematopoietic system.
Debecylina should be administered with great caution to avoid injecting the medicine directly into an artery or its immediate vicinity or into the area of nerves.

Debecylina and other medicines

Tell your doctor about all the medicines you are taking or have recently taken, as well as any medicines you plan to take.
In particular, inform your doctor if you are taking:

• Probenecid increases the concentration and prolongs the half-life of the medicine in the blood serum.
• Administering penicillin with bacteriostatic agents (erythromycin, tetracyclines) may reduce the bactericidal effect of penicillin.

Pregnancy and breastfeeding

If you are pregnant or breastfeeding, think you may be pregnant, or plan to have a child, consult your doctor before using this medicine.
If you are pregnant or think you may be pregnant
The medicine may be administered to pregnant women only if absolutely necessary.
If you are breastfeeding

Using a higher dose of Debecylina than recommended

Administering too high a dose of the medicine may cause severe side effects, including central nervous system irritation and seizures.

Do not take a double dose to make up for a missed dose.

4. Possible side effects

Like all medicines, Debecylina can cause side effects, although not everybody gets them.
Side effects after administration of Debecylina occur with an unknown frequency (the frequency cannot be determined from the available data).

Severe side effects

If you experience any of the following severe side effects, inform your doctor immediately.
Allergic reactions -allergic symptoms may occur in the form of hives, itching, rash, generalized skin inflammation, chills, fever, muscle pain. Severe allergic reactions, including anaphylactic shock (severe allergic reaction), angioedema (localized swelling, usually in the face or throat, which can be life-threatening), and serum sickness (characterized by hives with a burning sensation, fever, muscle pain, redness, and swelling of the joints) occur rarely and usually affect patients allergic to many allergens or with a history of asthma, rhinitis, or urticaria.
Jarisch-Herxheimer reaction - this reaction occurs due to the breakdown of bacteria and is characterized by fever, general malaise, and headache. It most often occurs during the treatment of early syphilis.
The appearance of the above symptoms during the treatment of early syphilis is not a threat. In patients with late-stage disease and organ damage, the Jarisch-Herxheimer reaction occurs very rarely, but its occurrence at this stage may lead to worsening of the disease and, consequently, to severe complications.
Severe diarrhea, persistent for a longer period or containing blood, accompanied by abdominal pain or fever. This may be a sign of severe colitis (pseudomembranous colitis), which may occur after antibiotic use.

Warnings regarding allergic reactions

Patients treated with penicillin may experience severe hypersensitivity reactions, especially those allergic to many allergens. Ensure that the patient is not allergic to penicillin, cephalosporins, or other medicines, and gather information about any past allergic reactions, regardless of their cause. The lack of data on hypersensitivity to beta-lactam antibiotics does not mean that such hypersensitivity does not occur in the patient.
If the administration of benzathine penicillin is necessary, and the patient has a history of allergic reactions (regardless of the cause), and a diagnostic test for hypersensitivity to this medicine is available, perform the test according to the instructions for use of the test. It is not recommended to perform a test with penicillin, as the administration of too high a dose may lead to shock or even death.
