What is a notable side effect of phenothiazines such as Haldol?

1. Anxiety

2. Insomnia

3. Tardive dyskinesia

4. Weight gain

The correct answer is: Tardive dyskinesia

Tardive dyskinesia is a notable side effect associated with phenothiazines, which are a class of antipsychotic medications commonly used to treat conditions such as schizophrenia and acute psychosis. This condition is characterized by involuntary, repetitive body movements, often affecting the face, lips, and limbs. It typically occurs after prolonged use of these medications, particularly in elderly patients or those on high doses. The risk of developing tardive dyskinesia emphasizes the importance of careful monitoring and the potential need for medication adjustment in patients receiving phenothiazines. Awareness of this side effect is crucial for healthcare providers to prevent or manage its occurrence, thereby improving treatment efficacy while minimizing adverse effects.
