  1. penicillin G

    Benzylpenicillin, also known as penicillin G (PenG) or BENPEN, and in US military slang "Peanut Butter Shot" is an antibiotic used to treat a number of bacterial infections. This includes pneumonia, strep throat, syphilis, necrotizing enterocolitis, diphtheria, gas gangrene, leptospirosis, cellulitis, and tetanus. It is not a first-line agent for pneumococcal meningitis. Due to Benzylpenicillin's limited bioavailability for oral medications, it is generally taken as an injection in the form of a sodium, potassium, benzathine, or procaine salt. Benzylpenicillin is given by injection into a vein or muscle. Two long-acting forms benzathine benzylpenicillin and procaine benzylpenicillin are available for use by injection into a muscle.Side effects include diarrhea, seizures, and allergic reactions including anaphylaxis. When used to treat syphilis or Lyme disease a reaction known as Jarisch–Herxheimer may occur. It is not recommended in those with a history of penicillin allergy. Use during pregnancy is generally safe in the penicillin and β-lactam class of medications.Benzylpenicillin is on the World Health Organization's List of Essential Medicines.


  1. penicillin G

    Penicillin G, also known as Benzylpenicillin, is a naturally occurring antibiotic derived from the Penicillium fungi. It is regarded as one of the earliest discovered and widely used antibiotics for the treatment of bacterial infections caused by susceptible organisms, such as streptococci, pneumococci, staphylococci and clostridium, among others. It serves by inhibiting bacterial cell wall synthesis, thus helping to fight against bacterial infections. However, it is ineffective against viruses. Penicillin G can be administered through oral consumption or intravenous injection, depending on the severity of the infection.
