Propafenone HCl
Propafenone HCl is an antiarrhythmic medication used primarily for the treatment of certain types of abnormal heart rhythms (arrhythmias), particularly ventricular and atrial arrhythmias such as atrial fibrillation and atrial flutter. It works by affecting the electrical conduction in the heart, helping to restore a normal rhythm and rate.

Frequently Asked Questions
Can I stop taking Propafenone suddenly?
It is not advisable to discontinue Propafenone abruptly without consulting your healthcare provider, as this may lead to a recurrence of arrhythmias.
Are there any dietary restrictions while taking Propafenone?
There are no specific dietary restrictions; however, it’s best to maintain a balanced diet and discuss any supplements with your healthcare provider.
What should I do if I miss a dose of Propafenone?
If you miss a dose, take it as soon as you remember. If it is almost time for your next dose, skip the missed dose and continue with your regular schedule. Do not double up on doses.
Is Propafenone safe for long-term use?
Propafenone can be used long-term under medical supervision, but regular monitoring is essential to evaluate its effectiveness and any potential side effects, particularly regarding heart rhythm and liver function.
Comprehensive Drug Guide
How Does Propafenone HCl Work?
Propafenone works by blocking sodium channels in the cardiac cells, which slows down the electrical conduction within the heart. This action stabilizes the cardiac membrane and reduces the likelihood of arrhythmias. It also has some beta-blocking activity, which can further help in managing heart rhythm and rate.
Common Dosages
- Tablets: 150 mg, 225 mg, and 300 mg
Typical Dosing
- For atrial fibrillation or flutter: The initial dose is usually 150 mg taken orally every 8 hours. Depending on the patient's response and tolerability, the dose may be increased to a maximum of 300 mg every 8 hours.
- For ventricular arrhythmias: Dosing will depend on the specific condition and should be determined by a healthcare provider.
Typical Dosing
FDA Approved Indications
- Treatment of paroxysmal atrial fibrillation and atrial flutter
- Prevention of recurrent episodes of atrial fibrillation
- Treatment of symptomatic ventricular arrhythmias
Off-Label Uses
Who Shouldn't Take Propafenone HCl?
- Known hypersensitivity to propafenone or any of its components
- History of significant heart block (unless a pacemaker is present)
- Uncontrolled heart failure
- Severe hypotension
Advice From The Pharmacist
- Take Propafenone HCl exactly as prescribed, and do not alter the dosage without consulting your healthcare provider.
- Regular follow-up appointments are essential to monitor heart rhythm and assess the effectiveness of the treatment.
- Report any signs of new or worsening arrhythmias, dizziness, fainting, or other concerning symptoms to your healthcare provider immediately.
Side Effects of Propafenone HCl
Common Side Effects
- Dizziness or lightheadedness
- Fatigue
- Nausea or vomiting
- Constipation
Uncommon/Severe Side Effects
- New or worsening arrhythmias
- Severe allergic reactions (such as rash, itching, or difficulty breathing)
- Liver function abnormalities
Risks and Warnings of Propafenone HCl
- Cardiac Monitoring: Patients starting on Propafenone should be monitored closely for any changes in heart rhythm, especially during the initiation of therapy or dosage adjustments.
- Liver Function: Regular monitoring of liver function tests is important, as Propafenone can cause liver enzyme elevations.
- Heart Failure: Caution should be exercised in patients with a history of heart failure, as Propafenone can exacerbate this condition.
Interactions with Propafenone HCl
Common Drug Interactions
- Other Antiarrhythmics: Use with caution when combined with other antiarrhythmic medications, as this may increase the risk of additive effects or toxicity.
- Beta-blockers: Concomitant use may enhance the effects of both medications, leading to increased bradycardia or hypotension.
- CYP450 Enzyme Interactions: Propafenone is metabolized by CYP2D6; drugs that inhibit or induce this enzyme may alter its effects.
Alternatives to Propafenone HCl
- Other Antiarrhythmics: Such as flecainide or amiodarone, which may be considered based on individual patient profiles and specific arrhythmias.
- Cardioversion: In some cases, electrical cardioversion may be used as an alternative treatment for atrial fibrillation or flutter.
