WARNING

Taking Tambocor (flecainide) comes with potential risks, and it’s important to be aware of these before starting the medication. Here are some key risks associated with Tambocor:

• Proarrhythmic Effects: Tambocor is an antiarrhythmic medication, but paradoxically, it can sometimes worsen existing arrhythmias or cause new ones. This risk should be carefully evaluated by your healthcare provider.
• Serious Cardiovascular Events: Tambocor may increase the risk of serious cardiovascular events, including heart attack, especially in individuals with pre-existing heart conditions.
• Worsening Heart Failure: For individuals with certain types of heart failure, Tambocor may increase the risk of worsening heart failure symptoms.
• Dizziness and Lightheadedness: Tambocor can cause dizziness and lightheadedness, which may affect the ability to perform tasks that require alertness, such as driving or operating machinery.
• Visual Disturbances: Some individuals may experience visual disturbances, including blurred vision or changes in color perception.
• Electrolyte Imbalances: Tambocor can affect electrolyte levels, particularly potassium. Individuals with conditions or medications that affect electrolyte balance may be at an increased risk.
• Individual Variability: Response to Tambocor can vary among individuals, and its effectiveness can be influenced by factors such as age, weight, kidney function, and other medications.
• Drug Interactions: Tambocor may interact with other medications, leading to potential adverse effects or reduced efficacy. It’s important to inform your healthcare provider about all the medications and supplements you are taking.
• Allergic Reactions: While rare, allergic reactions to Tambocor can occur. Seek immediate medical attention if you experience symptoms such as rash, itching, swelling, severe dizziness, or difficulty breathing.
• Pregnancy and Breastfeeding Risks: The use of Tambocor during pregnancy and breastfeeding should be carefully considered, as it may pose risks to the developing fetus or nursing infant.

It’s crucial to discuss these risks with your healthcare provider before starting Tambocor. The decision to use this medication is based on a thorough assessment of your medical history, current health status, and the specific arrhythmia being treated. Regular follow-up appointments and monitoring are typically recommended to assess the medication’s effectiveness and manage any potential side effects or risks. If you have concerns or experience any unusual symptoms while taking Tambocor, contact your healthcare provider promptly.

Why is this medication prescribed?

Tambocor (flecainide) is a medication prescribed to treat certain heart rhythm disorders, specifically those related to irregular heartbeats or arrhythmias. It belongs to the class of antiarrhythmic drugs and is used to help maintain a regular heart rhythm.

Conditions for which Tambocor may be prescribed include:

• Atrial Fibrillation or Atrial Flutter: These are conditions where the upper chambers of the heart (atria) beat irregularly, potentially causing an increased risk of blood clots and stroke.
• Supraventricular Arrhythmias: Tambocor may be used to treat certain types of rapid heartbeats originating above the heart’s ventricles.

How should this medicine be used?

The use of Tambocor (flecainide) should be strictly in accordance with the prescription and guidance provided by your healthcare provider. Here are general guidelines on how Tambocor is typically used:

• Dosage: The dosage of Tambocor will be determined by your healthcare provider based on factors such as the type and severity of the arrhythmia, your age, weight, kidney function, and other medical conditions. It is essential to take the prescribed dosage and not exceed it.
• Administration: Tambocor is usually taken orally in the form of tablets or capsules. It is commonly taken with or without food, but your healthcare provider may provide specific instructions based on your individual needs.
• Regular Schedule: Take Tambocor at the same times each day to maintain a consistent level of the medication in your body. This helps in achieving optimal therapeutic effects.
• Do Not Skip Doses: Take Tambocor regularly as prescribed. If you miss a dose, take it as soon as you remember. However, if it’s almost time for your next scheduled dose, skip the missed dose and continue with your regular dosing schedule. Do not double up on doses to make up for a missed one.
• Avoid Abrupt Discontinuation: It’s important not to stop taking Tambocor suddenly without consulting your healthcare provider. Abruptly stopping the medication can lead to a rebound effect and may worsen arrhythmias. Your doctor will provide guidance on how to gradually reduce the dosage if discontinuation is necessary.
• Regular Monitoring: Your healthcare provider may monitor your heart rhythm regularly through electrocardiograms (ECGs) or other tests to assess the effectiveness of Tambocor and to make any necessary adjustments to your treatment plan.
• Reporting Side Effects: If you experience any unusual or severe side effects while taking Tambocor, such as dizziness, chest pain, shortness of breath, or a rapid or irregular heartbeat, contact your healthcare provider immediately.
• Informing Other Healthcare Providers: Make sure to inform other healthcare providers, including dentists and specialists, that you are taking Tambocor. This is important in case of any interactions with other medications or medical procedures.

Remember, these guidelines are general and may not cover all individual considerations. Always follow the specific instructions provided by your healthcare provider and ask them any questions you may have about your medication. If you have concerns or experience any side effects, seek medical advice promptly.
