Perkin Trans. 1 (1978) 185-190 (CSD Entry: BZPENK01). Colour code: &#x2002; Carbon, C: grey &#x2002; Hydrogen, H: white &#x2002; Nitrogen, N: blue &#x2002; Oxygen, O: red &#x2002; Sulfur, S: yellow Model manipulated and image generated in CCDC Mercury 3.8.
context_page_description: Benzylpenicillin, also known as penicillin G, 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. 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. It is in the penicillin and β-lactam class of medications.
  Benzylpenicillin was discovered in 1929 by Alexander Fleming and came into commercial use in 1942. It is on the World Health Organization's List of Essential Medicines.
