What is a known side effect of haloperidol (Haldol) in children?

1. Hyperactivity

2. Excessive weight gain

3. Tardive dyskinesia

4. Increased anxiety

The correct answer is: Tardive dyskinesia

Haloperidol is an antipsychotic medication that is often used to treat various psychiatric conditions, including schizophrenia and severe behavioral problems in children. One of the significant concerns with long-term use of haloperidol, particularly in children, is the risk of tardive dyskinesia. This condition is characterized by abnormal, involuntary movements, often of the face and tongue, and can occur after prolonged exposure to the medication. Tardive dyskinesia is a serious and sometimes irreversible side effect of antipsychotic drugs, making this a critical consideration for clinicians prescribing haloperidol to children. The risk increases with the duration of treatment and the dosage of the drug. Tardive dyskinesia is especially concerning in the pediatric population, where neurodevelopmental factors may amplify the risk and impact of such side effects. While hyperactivity, excessive weight gain, and increased anxiety may occur with other treatments or medications, they are not characteristic side effects specifically associated with haloperidol. Thus, understanding the significant risk of tardive dyskinesia with haloperidol use is essential for safe and effective treatment planning in children.
