Flecanide

[Paddbear]

I have just realised that I have been taking 2 x 200mg of Flecanide for the last week, instead of 2 x 150mg. I have been feeling as if I was going to pass out several times recently. I have now realised that the 100mg (new packages), look like the 50mg hence the mistake. Should I be concerned , feeling OK now.

Oops, anyone else overdose and did you feel similar?

That must have been a shock for you. I once took 200mg at once by mistake but noticed almost immediatel.

I'm glad you feel OK now but as 300mg is normally considered to be the maximum daily dose, I would be inclined to get checked out with your doctor. The good thing is that you noticed the mistake and only took the extra dose for a week.

Hi Paddbear.

I would certainly check with your doc. I'm sure you'll be OK but taking to much flec can lead to flutter - I know as it happened to me!

At least you spotted it and I'm sure you'll be OK. As Finvola say's 300mg is considered to be the maximum dose so you are within limits so to speak.

Thanks Paulbounce, but I've been taking 400mg a day, no wonder I have been feeling bad, anyway will try to contact the doctor tomorrow, many thanks

Hi Paddbear. 400mg a day is far to high IMO unless your medic suggests this. For sure I would contact your doctor tomorrow. Flec is a strong drug and not to messed with - it's very important to follow your doctors advice on the correct dose to take.

Good luck and post how it goes.

I think the half life of Flecanide (time taken for drug concentration in body to reduce by 50%) is 17 hours. So you should be down to normal levels by now. I think if you feel ok now you should be fine.

I think your be ok but 300mg is thee we highest you should take normally

Thanks for the reminder to check!

Allowed dosage can be as high as 400mg daily but only for life-threatening venture alar arrhythmias.

As other posters state, 300mg/day is usually max dosage for AF. That said, one needs to bear in mind body/size/mass. 300mg would be too much for a 55kg female, but perhaps not so big of a deal for a 110kg 2m tall male with no co-morbities.
