Travellers familiar with Benzetacil from Latin America or southern Europe are unlikely to encounter the same brand elsewhere — it is registered in only five countries. The active ingredient is benzylpenicillin, one of the original members of the penicillin family and classified pharmacologically as a bactericidal agent.
Benzylpenicillin-containing products are prescribed across a wide range of bacterial infections, including respiratory infections such as bronchitis and pneumonia, soft-tissue infections, abscesses, certain sexually transmitted infections such as gonorrhea, Lyme disease, and febrile presentations of bacterial origin. The structured indication list further down this page details each registered use as recognised in the markets where Benzetacil is sold. The drug sits within the broader injectable-penicillin category, which has been a backbone of antibacterial therapy for decades.
Outside its core markets — Brazil, Spain, Venezuela, Ecuador, and Slovenia — the Benzetacil brand itself is uncommon, but benzylpenicillin as a molecule remains available in essentially every regulated healthcare system in the world. A patient prescribed Benzetacil at home and now travelling will, in most countries, find benzylpenicillin available under a different brand name, often as the long-acting benzathine formulation that is standard for several of the indications listed above.
Other antibiotics in the bactericidal penicillin class also circulate widely, although they are not freely interchangeable — choice of agent depends on the specific infection, regional resistance patterns, and patient-level factors. A local pharmacist can usually translate the brand into a regional equivalent based on the active ingredient, but the prescribing decision itself — including whether benzylpenicillin remains the right choice in a given setting — belongs with a healthcare provider familiar with the patient.
Benzetacil and solutions that contain metal ions should be administered separately.
Benzetacil should not be administered in the same syringe / giving set as amphotericin B, cimetidine, cytarabine, flucloxacillin, hydroxyzine, methylprednisolone, or promethazine since it is incompatible with these drugs.
In the absence of compatibility studies, this medicinal product must not be mixed with other medicinal products
Benzetacil sodium and solutions that contain metal ions should be administered separately.
Benzetacil sodium should not be administered in the same syringe / giving set as amphotericin B, cimetidine, cytarabine, flucloxacillin, hydroxyzine, methylprednisolone, or promethazine since it is incompatible with these drugs.

There are no pre-clinical data of relevance to the prescriber which are additional to that already included in other sections of the SmPC.
Benzetacil rapidly appears in the blood following intramuscular injection of water-soluble salts and maximum concentrations are usually reached in 15-30 minutes. Peak plasma concentrations of about 12 mcg/ml have been reported after doses of 600 mg with therapeutic plasma concentrations for most susceptible organisms detectable for about 5 hours. Approximately 60% of the dose injected is reversibly bound to plasma protein.
In adults with normal renal function the plasma half-life is about 30 minutes. Most of the dose (60-90%) undergoes renal elimination, 10% by glomerular filtration and 90% by tubular secretion. Tubular secretion is inhibited by probenecid, which is sometimes given to increase plasma penicillin concentrations. Biliary elimination of Benzetacil accounts for only a minor fraction of the dose.

After contact with skin, wash immediately with water. In case of contact with eyes, rinse immediately with plenty of water and seek medical advice if discomfort persists.

Benzetacil is prescribed for a range of bacterial infections, including bronchitis, pneumonia, abscesses, soft-tissue infections, gonorrhea, Lyme disease, and bacterial infections presenting with fever. It belongs to the bactericidal penicillin category, one of the longest-established antibiotic classes in clinical use. The structured indication section below this introduction lists each registered indication for Benzetacil in the markets where it is sold.
Benzetacil contains benzylpenicillin, classified as a bactericidal agent within the penicillin family. Benzylpenicillin is one of the original antibiotic molecules and is available worldwide under a variety of brand names, including long-acting benzathine formulations frequently used for several of the indications above. The Benzetacil brand is one of many commercial presentations of the same underlying active ingredient.
Benzetacil is registered in five countries: Brazil, Spain, Venezuela, Ecuador, and Slovenia. Outside this small footprint the specific brand is uncommon, but benzylpenicillin as an active ingredient is available in essentially every regulated healthcare system worldwide. If your country is not on this short list, a local pharmacist can confirm which benzylpenicillin-containing products are stocked in that market.
Benzylpenicillin is sold internationally under several brand names, including widely used long-acting benzathine formulations. Other antibiotics within the broader bactericidal penicillin class also exist, although they are not interchangeable without medical guidance — selection depends on the specific infection, local resistance patterns, and individual patient factors. To identify a regional product, search the active ingredient on Pill2Trip or ask a pharmacist in your country.
Yes. Benzetacil is a prescription antibiotic, and antibiotic therapy in general is calibrated to the specific infection, the patient's history, and local resistance considerations. Prescription rules and available formulations differ between countries, which matters particularly for travellers and people relocating across borders. Any decision to start, stop, switch, or substitute benzylpenicillin should be made together with a healthcare provider, not improvised at a pharmacy counter.
