This medication can cause various side effects including blood cell reduction, hepatitis, kidney issues, allergic reactions, gynecomastia, digestive disorders, neurological issues, and skin reactions; therefore, patients should consult a physician immediately when symptoms occur. Particularly in elderly or patients with deteriorated kidney function, attention should be paid to neurological side effects such as confusion or seizures.

Pregnant women or those who may become pregnant should use this medication only when the benefits outweigh the risks, and breastfeeding should be paused if using this medication.

In the case of overdose, respiratory depression and other issues may occur, and immediate medical care should be sought.
