Y40: Systemic antibiotics

Y40.0: Penicillins

Penicillins are a group of antibiotics frequently used to treat a variety of bacterial infections. However, an unintended consequence of their use can be adverse effects or complications, which is what the ICD-10 code Y40.0 refers to. Patient reactions to penicillins can vary greatly. Some may experience mild symptoms like a rash, diarrhea, or nausea, while others might have serious reactions like anaphylaxis, a severe and potentially life-threatening allergic reaction. Anaphylaxis can cause a sudden drop in blood pressure, shortness of breath, and rapid, weak pulse. Other serious complications can involve the kidneys or the nervous system. The likelihood of these reactions can depend on numerous factors, including the dosage, the method of administration, the duration of treatment, and the individual's own medical history.
