What is a common side effect of olanzapine, an atypical antipsychotic?

Weight gain is a well-documented side effect associated with olanzapine, which is often classified as an atypical antipsychotic. This phenomenon can be attributed to several factors, including changes in metabolism and alterations in appetite regulation. Olanzapine impacts various neurotransmitter systems, including serotonin and histamine, which can lead to increased hunger and cravings, particularly for carbohydrates.

Patients taking olanzapine are often advised to monitor their weight regularly and maintain a balanced diet and physical activity, as the weight gain associated with this medication can contribute to long-term health issues such as metabolic syndrome and cardiovascular diseases. This makes it essential for healthcare providers to consider this side effect when prescribing olanzapine, especially for patients who may be at risk for weight-related health concerns.
