What precautions should be taken during the use of Cedilanid?

　　Cedilanid usually refers to acetyldigitoxin injection. Acetyldigitoxin injection is a prescription drug, and the patient's physical response must be strictly monitored during treatment. Key considerations generally include monitoring heart rate and rhythm, controlling dosage, watching for signs of toxicity, maintaining electrolyte balance, and avoiding drug interactions. If there are any concerns, it is recommended to consult a healthcare provider in advance. The detailed analysis is as follows:

　　1. Monitor heart rate and rhythm: Continuous monitoring of heart rate and rhythm is required during treatment. If bradycardia (heart rate below 60 beats per minute) occurs, or arrhythmias such as ventricular premature beats or atrioventricular block appear, medical staff should be informed immediately for medication adjustment.

　　2. Control dosage: The drug has a narrow therapeutic window; insufficient dosage may reduce efficacy, while overdose can easily cause toxicity. Dosage must be precisely calculated by medical professionals based on the patient’s weight, liver and kidney function, and clinical condition. Patients should never adjust the dose on their own.

　　3. Watch for toxic reactions: Closely observe for symptoms of toxicity such as nausea, vomiting, blurred vision, yellow or green vision (xanthopsia or chloropsia), dizziness, or headache. If any of these symptoms occur, discontinue the drug promptly and receive appropriate symptomatic treatment.

　　4. Maintain electrolyte balance: Hypokalemia or hypomagnesemia increases the risk of drug toxicity. Electrolyte levels should be regularly tested during treatment, and any imbalances should be corrected promptly through dietary changes or supplements.

　　5. Avoid drug interactions: This medication may interact with calcium-containing agents, diuretics, antiarrhythmic drugs, and others. Inform healthcare providers of all medications currently being used before starting treatment to avoid risks associated with combination therapy.

　　Acetyldigitoxin injection must be administered by qualified healthcare professionals within medical institutions. Patients and their families should not purchase or adjust the medication on their own. Close cooperation with all monitoring procedures is essential during treatment. Any discomfort should be reported immediately, and patients must strictly follow medical instructions to complete the treatment course safely.
