Jisanda is a core drug for the treatment of hepatitis C, but extra caution should be exercised in specific combination therapy or postoperative populations. The combination with amiodarone may cause severe bradycardia, and there are special requirements for the timing and monitoring of medication in liver transplant patients. The following outlines the core precautions in two aspects.

1、 Risk of bradycardia in combination with amiodarone

1. It is prohibited to use Jisanda in combination with amiodarone (an antiarrhythmic drug) without close monitoring.

2. Combined use can cause severe symptomatic bradycardia, even requiring pacemaker intervention or endangering life.

3. If combined use is necessary, it should only be performed under hospitalization or electrocardiogram monitoring conditions, and heart rate should be continuously monitored for the first 48 hours.

4. It is recommended to monitor heart rate daily or use home electrocardiographic devices until at least 2 weeks after discontinuing amiodarone.

When using beta blockers or other heart rate lowering drugs in combination, the risk of bradycardia further increases and follow-up needs to be strengthened.

2、 Key points of medication for liver transplant patients

1. After liver transplantation, patients can be treated for recurrent or newly developed hepatitis C infection.

2. Treatment should be initiated when the condition stabilizes and liver function indicators tend to stabilize after transplantation, and the specific timing should be evaluated by the transplantation team.

3. It is necessary to closely monitor the blood concentration of immunosuppressants such as tacrolimus or cyclosporine, as their levels may be elevated in the third generation of Jiji.

During the treatment period, it is necessary to repeatedly adjust the dosage of immunosuppressants and regularly monitor liver function and signs of rejection.

5. It is recommended to develop individualized medication plans through multidisciplinary collaboration in transplant centers, avoiding self medication or adjustments.
