Pulcard Tablet (Flecainide Acetate)

Adult dose

Adults: The initial dose is flecainide acetate 50-100mg orally twice daily. The maximum daily dose is 400mg; this dose is generally used in patients with a large body size or those requiring rapid treatment of arrhythmia. After 3-5 days of treatment, gradually reduce the dose for maintenance treatment of arrhythmia. The dose may be reduced for long-term treatment. Because the plasma clearance of this medicine is reduced in elderly patients, the usual dose is 100mg twice daily, which may be reduced to a maintenance dose after 1 week. In patients with severe renal impairment (creatinine clearance 35ml/min or less), it is preferable not to exceed a maximum daily dose of 100mg. When administering to these patients, monitor blood concentrations frequently. Adjust the dose as appropriate according to age and symptoms.

Child dose

Children aged 12 years and older: The initial dose is flecainide acetate 50-100mg orally twice daily. The maximum daily dose is 400mg

This medication should not be used in patients with severely impaired cardiac function, such as those with heart failure. It is safe not to administer to patients with problems in the transmission of electrical signals in the heart or those with very slow heart rates. Using this medication may pose risks for patients with significant heart damage or abnormalities in heart rhythm. Women who are pregnant or may become pregnant should not take this medication. Additionally, this medication contains lactose, so patients with lactose intolerance or certain genetic metabolic disorders should not take it. Patients with existing heart disease or elderly patients should take special care when using this medication, and patients with liver or kidney function issues should also be cautious. During treatment with this medication, regular monitoring of heart rate and blood pressure is necessary, and changes in electrical signals in the heart should be carefully observed through electrocardiograms. If the heart rate becomes too slow or abnormalities in the electrical signals of the heart are discovered, stop using the medication immediately and consult a physician. It is advisable not to use this medication in conjunction with other antiarrhythmic agents, and caution should be exercised as side effects can occur when taken with certain medications. Pregnant or nursing women are advised to avoid this medication, and if it is necessary to use it, breastfeeding should be stopped. The safety of this medication has not been sufficiently established in children, so its use is not recommended. In cases of overdose, there is no specific antidote, thus it is crucial to visit a hospital quickly to receive appropriate treatment, and supportive treatment for heart function may be necessary. Long-term use of this medication may result in abnormalities in the eyes or lungs, so regular check-ups are necessary. Finally, this medication can increase mortality in patients with severe heart disease, therefore it must be taken according to a physician's instructions.
