I've recently been prescribed Tambocor 100mg Tablets (Flecainide) for my irregular heartbeat (arrhythmia). I'm a bit nervous about starting a new medication, especially one that's been described to me as having some serious potential side effects. I'm taking it exactly as prescribed, but I'm wondering if anyone else out there has some experience with it. What were your biggest concerns? What were the side effects like? What did you do? Should I be worried about the heart failure risks? I'd be really grateful for any insights or advice you can share!

I've been on Flecainide for a few months now. The most annoying side effect for me has been dizziness, but it's manageable. Make sure you're taking it with food to avoid an upset stomach. Good luck!

I've been on Flecainide for a couple of years now. The first few weeks were tough with dizziness. I called my doctor and we adjusted the dose a bit. Now I'm feeling great. Also, make sure you monitor for any vision changes. It's rare, but it can happen.

If you have any history of heart disease, make sure your doctor knows. My grandmother almost died from heart problems after taking this medication for just a few days, and it was because of a history she didn't disclose.

I've been on this for a while and haven't had any major issues. Just some dizziness that went away after a few days. But seriously, if you start feeling any chest pain or shortness of breath, get to a doctor ASAP.

I've had a great experience with this medication. I didn't have any serious side effects, just a bit of fatigue. But I've heard the horror stories too, so definitely stay in touch with your doctor. Keep a symptom diary and report any changes immediately.

Be really careful with this one. I had a friend who ended up in the hospital with severe dizziness and an irregular heartbeat. Please monitor your symptoms closely.

Make sure you're not doing anything too strenuous when you start taking it. The dizziness can be pretty bad at first. Also, keep an eye on your weight! Sudden weight gain can be a sign of heart failure, and that's not something to mess around with.

I took this for a while and it wasn't good for me. I had a lot of dizziness and headaches, but honestly, the worst was the constant feeling of like my heart was racing. It was terrifying.
