I have heard of patients taking i\t on an "as needed" basis. I guess that means your SVT isn't that bad where you need it daily, so that is a good thing.
I think it depends on which brand you're using. Some of them are in "slow release" formula (so a dose of say 25 mg is released through 24 hours) and will not work as a "pill in the pocket".
I have a beta blocker for use when needed, but that one is propranolol and not metoprolol (slow release). Propranolol works better towards anxiety, stress and other factors that may trigger a rapid heart rhythm. From time to time (generally stressful times) I can take 12,5 or 25 mg metoprolol in addition.
But I guess this is something that your doctor should decide as we are all different.
I've received two different instructions from my family physician, and my cardiologist. The former put me on 100mg/day and told me that if I had an SVT event, to chew on one, and that it would help in converting it. When I told my cardiologist, he politely told me that "it doesn't work that way". So take your choice. Regardless, I found Metoprolol ineffective in preventing episodes, which in my case had grown to 3 to 5 times per month. I do think however that the drug helped in converting episodes. I had a self sustaining form of SVT that once initiated, would run on until I intervened or I guess dropped over.
Metoprolol come is both slow release and in normal release, the normal release is much lower cost in the USA and is called Metoprolol Tartarait (sp?). I used the slow release once a day for a few years but got approval to move to the regular release taken at 1/2 the former dose rate, but I take it twice a day. I do not suffer from SVT, but I do take BB.
Hi! I know im a little late but I was wondering what your outcome was with taking it as needed. I am in the same position you were. I hope you get a chance to read this.
