Y49.3: Phenothiazine antipsychotics and neuroleptics

Phenothiazine antipsychotics and neuroleptics are a type of medication used to manage psychological disorders like schizophrenia and other conditions that lead to severe emotional disturbances. These drugs work by blocking certain chemicals in the brain, helping to balance its function. While they can be helpful, they can also cause complications sometimes known as antipsychotic poisoning. This can happen if someone uses too much of the medication, either accidentally or intentionally. Symptoms can include restlessness, tremors, muscle stiffness, confusion, and changes in heart rhythm. These medications may also cause the movement disorder known as tardive dyskinesia, characterized by repetitive, involuntary movements, especially of the face. Long-term use, particularly at high doses, increases the risk of these complications.
