Anyone have good knowledge of different beta bockers and dose equivalents?

Edited , 5 users are following.


First time poster here. Not sure where else to ask this so I figure i'd give this place a try.

For multiple reasons which i'd rather not explain at this point, i have been on a steady dose of 10mg propranolol, twice a day for 10 years now. It works well and helps me get through the day, but having the need to take it twice a day is becoming quite annoying, so i'm trying to find something like this drug that i can take once a day. My doctor (who is a replacement from my original doctor who put me on the drug) does not seem very keen to help with this. Basically i was offered a 50mg Atenolol prescription which i turned away considering the strong dose. I don't want to take such a dose when 10mg twice a day works fine for me of propranolol. I don't want to over dose this medicine into my body when it does not require it, but i cannot find anything else that would be a good equivalent.

DOes anyone know what would be a similar replacement that i could potentially try and switch over to? Another beta blocker that is close (wouldn't mind if its a little higher) to 10mg propranolol, but one that i could take only once a day.

    10mg of one drug can be the equivalent of 50mg of another drug - or 5mg or 500mg. It varies widely from drug to drug.

    50mg of atenolol is just the standard dose.

    You will find variations like that between all sorts of related and unrelated medicines.

    OK i've just managed to find a converter chart online of sorts, and it seems there are no beta blockers out there that can be taken one a day, that is an equivalent or close to 10mg propranolol. What a crazy age we live in with modern medicine but something so simple does not exist 😕

      What do you mean no equivalent?

      I just looked at that calculator, it's nice, but it says 10mg propranolol equivalent is 6.25mg of atenolol. So what's the problem?

      They don't make 6.25mg atenolol pills, right?

      That's a pretty tiny dose!

      The smallest pill is 25mg, and they are tiny - I know, because I cut them in half myself, and it's not easy to do accurately on a standard drugstore pill cutter.

      But my doctor already thinks I'm crazy taking just 12.5mg atenolol once a day!

      But you take your propanolol twice a day, so that would be - the same as my 12.5mg dosage. So if you want to join me, come ahead!

      BTW, if you really want it done accurately, get your atenolol at a "compounding pharmacy", they will grind it up and make you some pills exactly 12.5mg or any other size you want.

    I've been concerned with all the drugs I'm prescribed so I went to the Mayo Clinic

    website to see what they do & the side effects. Is the drug prescribed by your GP ?

    I've been prescribed drugs by my cardiologist, kidney specialist & GP. I feel I'm being

    stuffed with too many drugs.
