    Default 3000 mg's Metformin?

    Is anyone on that many mg's? I was always under the impression that the dose I am currently on, 850 three times a day, or 2550, was the maximum?

    I was on 3000mg until I got pregnant and they took me down to 2500mg. My RE said that 2550 is technically the recommended dose maximum but he prescribes 3000mg sometimes as long as there is no ill effects. I took 3000mg for 13 months.

    Did you do three 1000 mg doses a day? What dose did you start at? I've been researching and there are some sites recommending 3000!

    Yes I did 1000 mg 3x a day (breakfast, lunch, and dinner). I started at 1000mg a day and and got up to 1500 where I stayed for a long time. It wasn't helping me much so that's when the RE upped me to 3000mg. I didn't work up to that I just added it right away with no problems.

    I think some doctors go to 3,000 just because it's easier to prescribe 3 1,000mg pills than it is to try and mix and match the other pills to get 2,500. Prescribing info lists 2,500 as the max recommended dose. I don't think it's harmful to go higher than that - just ineffectual for the most part.

    I take 2,500mg per day.

    Max dose is mostly listed as 2550, or three 850 mg pills a day. That's what I'm taking now. I've been reading some research, especially in other countries, where 3000 is the max and seems to be working well!

    The maximum recommended dose is 2550 mg, which technically would be 850 three times a day. This refers to the immediate release, as with extended release, there is no reason to take it more than twice a day.

    Some physicians have used up to 3000 mg, but studies out there using this dose has shown that it offers little benefit above 2500mg, but with the added cost of increased side effects, and worry about possible serious side effects. If you can't get the response that is needed with 2500mg, then you won't get it with 3000mg either, but will just punish the patient with the extra side effects.
