Y40: Systemic antibiotics

The ICD-10 group range Y40 refers to complications of systemic antibiotics, rather than a specific disease. Systemic antibiotics are medications taken by mouth or injected into the body to fight bacterial infections. While they are generally safe and effective, misuse or an unexpected reaction may result in complications, which can affect various body systems. Common issues may include digestive system upsets, such as nausea, vomiting, and diarrhea. Allergic reactions can also occur, including rash, swelling, or trouble breathing. In rare cases, overuse of antibiotics can lead to antibiotic resistance, where certain bacteria no longer respond to a specific antibiotic. This can make future infections harder to treat. It's important to remember these outcomes are not diseases themselves but potential complications or adverse effects related to the use of systemic antibiotics.
