Could my Metformin dose be too high?

My endo started me on Metformin 750 mg twice a day but since starting it, I've been getting horrible headaches and light headed and nausea. Before starting it about two months ago, my a1c was 5.4 and my fasting bs was 106. Insulin was 20.

Re: Could my Metformin dose be too high?

Do you take it with meals? Metformin can raise some havoc on your system on an empty stomach. I take 500 mgs. once a day with my largest meal. When first put on it I tried taking it in the a.m. and ran into all sorts of problems...headache..stomach pains and Diarrhea. Dr. told me to cut them in half to 250 mgs. for two weeks and then up it to the 500.

750 mgs. twice daily seems like a lot especially if your A1c was 5.4 and fasting glucose at 106. Maybe you should call the Dr. and tell him/her of your problems and see if you can maybe cut the dosage till you get use to it.

Best of wishes and keep us posted...JJ...

Re: Could my Metformin dose be too high?

I am surprised that he would prescribe metformin with an A1c of 5.4, especially a higher dose. Am I missing something? Does diabetes run in your family? Have you tried diet and exercise? I would be delighted to have that A1c. Mine is around 6.2 and my doctor does not want me to take metformin, but to continue diet and exercise.

I do take it with meals.

It's actually more for PCOS. But he said that I'm going to develop diabetes in the future b/c of my insulin resistance.

Re: Could my Metformin dose be too high?

Have you had your A1c checked since starting the metformin?

Re: Could my Metformin dose be too high?

I think you should call your Dr. and tell him/her about your symptoms. With your A1c and glucose being in the normal range I think 750 twice a day is a bit weird. I know it is for the PCOS but still, that is a fairly high doseage in my opinion. Don't understand him saying your going to be Diabetic anyway, why not wait till you do show signs. Being pro active is one thing, but I think in this case he/she went a bit overboard...JMHO

Good luck...JJ....

I thought it was a bit odd too...my PCOS isn't even severe. I have elevated testosterone and all...but I still get a period every month. I'll ask my primary doctor about it when I see her...get her opinion on it.

Re: Could my Metformin dose be too high?

Hon...I would definately ask as it is really weird in my opinion. Like I said, my A1c was 6.4 and she was undecided whether to put me on meds. or not. Usually they don't till it is about 6.7-6.8..some not till it's 7, and I'm only on 500 mgs. once a day. Keep us posted.

Good luck...JJ...
