What is a common side effect associated with antipsychotic medications used to treat schizophrenia?

Tardive dyskinesia is a common side effect associated with antipsychotic medications, particularly the older typical antipsychotics, though it can also occur with newer atypical antipsychotics. This condition is characterized by involuntary, repetitive movements, often affecting the face, tongue, and limbs. It results from long-term use of these medications, which are designed to manage the symptoms of schizophrenia.

Understanding this side effect is crucial, especially since it can significantly impact the quality of life for patients. Tardive dyskinesia can sometimes be irreversible, making it vital for healthcare providers to monitor patients on these medications regularly.

Other options presented do not accurately reflect common side effects of antipsychotic medications. For example, antipsychotics typically do not lead to increased energy and may instead cause sedation. Weight reduction is not commonly seen; rather, many patients experience weight gain as a side effect. Improvements in mood stability can occur but are primarily the therapeutic outcomes rather than side effects associated with the medication use.
