4.Abnormal thyroid function: Monitor thyroid function regularly and correct hyperthyroidism or hypothyroidism in a timely manner.

4. Side Effect Management Strategies

1.Monitoring and prevention: Conduct regular comprehensive physical examinations and biochemical indicator monitoring to detect and deal with side effects in a timely manner.

2.Dose adjustment: Depending on the severity of side effects, flexibly adjust the drug dose or briefly discontinue the drug.

3.Indications for discontinuation of medication: If severe liver damage, interstitial pneumonia or uncontrollable mental symptoms occur, medication should be discontinued immediately.
