Precautions

This medication may increase the risk of suicidal thoughts or behaviors, so patients should carefully monitor for signs of depression, mood changes, or behavioral abnormalities while taking it. Pregnant women or those who may become pregnant, as well as individuals allergic to any components of this medication, should not take it. Patients with lactose intolerance or certain genetic disorders should also avoid taking this medication. Patients with liver function issues or allergy history should take this medication cautiously. Side effects including drowsiness, reduced appetite, abnormal movements, nausea, hallucinations, and fatigue may occur, so caution should be exercised. In severe cases, conditions such as malignant syndrome, skin rashes, allergic reactions, blood disorders, acute renal failure, interstitial pneumonia, and liver dysfunction may arise; patients should consult a doctor immediately if symptoms appear. This medication can cause significant mental symptoms like hallucinations, delusions, and confusion, so changes in mental status should be closely observed. During treatment, regular liver and kidney function tests are necessary, and patients should avoid driving cars or operating hazardous machinery due to drowsiness or decreased concentration. There may be issues with temperature regulation leading to reduced sweating and an increased risk of heat stroke, especially in hot environments. This medication may interact with other drugs, so patients must inform their doctor of any other medications they are taking. There is a risk of fetal malformation if taken during pregnancy; therefore, women who are pregnant or planning to become pregnant should not take this medication, and breastfeeding women should avoid nursing. Safety in pediatric patients has not been established, so it is recommended not to use this medication in children. Elderly patients should be closely monitored as liver and kidney functions may be diminished. In cases of overdose, symptoms such as coma, muscle spasms, and eye tremors may occur, and there is no specific antidote, so immediate hospital treatment is required.
