Y46: Antiepileptics and antiparkinsonism drugs

The ICD-10 Y46 category designates conditions resulting from harmful effects of antiepileptic and antiparkinsonism drugs. These drugs are meant to manage conditions like epilepsy, which is characterized by recurrent seizures, and Parkinson's disease, a progressive nervous system disorder that affects movement. Misformulation, overdose, or an individual's adverse reactions to these medications can result in harmful effects. Symptoms of such circumstances can vary widely but often include issues related to nervous system functions such as dizziness, disorientation, balance problems, and potentially severe effects like a significant decline in motor function or increased frequency and severity of seizures. It's important to note that while these harmful effects typically result from medication errors, they can occasionally occur even with proper drug administration due to individual differences in drug metabolism and sensitivity.
