Y45.9: Analgesic, antipyretic and anti-inflammatory drug, unspecified

The ICD-10 code Y45.9 pertains to side effects or adverse events related to the use of analgesics, antipyretics, or anti-inflammatory drugs. These are a broad range of medications that are typically used to alleviate pain (analgesics), lower fever (antipyretics), or reduce inflammation (anti-inflammatory drugs). While these medications can be beneficial in managing symptoms or conditions, they may also lead to adverse reactions in some individuals. These undesirable reactions can vary widely, from mild effects such as nausea or diarrhea, to more serious ones, such as ulcers, allergic reactions, or kidney problems. These reactions can emerge shortly after starting the medication or after prolonged use. Individual reactions can differ greatly, depending on factors such as the person's overall health, age, or the specific medication used. Always consult with your healthcare provider if you are experiencing any unusual symptoms after starting a new medication.
