I have a-fib with a rapid resting heart rate. my cardiologist just prescribed 50mg metoprolol succinate twice a day ( i was taking 25mg/day). i read that the succinate should be taken only once a day.is it safe to take it twice a day like prescribed?

You are correct, the succinate formula is a long acting metoprolol which should be taken just one a day. However, it is still safe to take twice a day instead one a day although some insurance does not cover twice a day because more pills (more cost). Total daily dose can be up to 400 mg/day in some cases. You can ask your cardiologist for 100 mg tablets if insurance does not cover twice a day.

Yes, sometimes prescribed twice a day, the actual daily dose remains important, confirm with cardiologist, unusual increase from 25 to 100 mg per day.

Metoprolol succinate is usually dosed once daily, but there is no problem taking it twice a day if that’s what the prescribing doctor intended.
