ICD-10: T43.3X5

The ICD-10 code T43.3X5 refers to the adverse effects of phenothiazine antipsychotics and neuroleptics. This classification is part of the broader International Classification of Diseases, which is used for coding various health conditions and their effects. Below is a detailed clinical description and relevant information regarding this code.

Overview of Phenothiazine Antipsychotics and Neuroleptics

Phenothiazine antipsychotics are a class of medications primarily used to manage psychotic disorders, including schizophrenia and severe anxiety. They work by blocking dopamine receptors in the brain, which helps to reduce symptoms such as hallucinations and delusions. Common examples include chlorpromazine, fluphenazine, and thioridazine.

Neuroleptics, often synonymous with antipsychotics, encompass a broader range of medications that can include both typical (first-generation) and atypical (second-generation) antipsychotics. While effective in treating various psychiatric conditions, these medications can lead to a range of adverse effects.

Clinical Description of Adverse Effects

The adverse effects associated with phenothiazine antipsychotics and neuroleptics can be categorized into several groups:

1. Extrapyramidal Symptoms (EPS)

These are drug-induced movement disorders that can include:
- Akathisia: A feeling of inner restlessness and an uncontrollable need to be in constant motion.
- Dystonia: Involuntary muscle contractions, which can lead to abnormal postures.
- Parkinsonism: Symptoms resembling Parkinson's disease, such as tremors, rigidity, and bradykinesia.

2. Tardive Dyskinesia

This is a serious and often irreversible condition characterized by repetitive, involuntary movements, particularly of the face and tongue. It can develop after long-term use of antipsychotic medications.

3. Sedation and Cognitive Impairment

Patients may experience drowsiness, sedation, and cognitive deficits, which can affect daily functioning and quality of life.

4. Metabolic Effects

Atypical antipsychotics, in particular, can lead to weight gain, diabetes, and dyslipidemia, increasing the risk of cardiovascular diseases.

5. Neuroleptic Malignant Syndrome (NMS)

This is a rare but life-threatening condition characterized by severe muscle rigidity, fever, autonomic instability, and altered mental status. It requires immediate medical attention.

6. Cardiovascular Effects

Phenothiazines can cause orthostatic hypotension, tachycardia, and other cardiovascular issues, particularly in elderly patients.
