Just bumping this again a couple of years later.

Is anyone on Metformin (other than as a diabetic)?.

My blood glucose is climbing on HT, although not outside normal range yet. Consultant mentioned metformin as a good thing, knowing that I would have read about STAMPEDE. Spoke to my GP who was a bit reluctant as it's quite a liver toxin and I'm not yet above 6mmol/L blood glucose (which is not quite the point for PCa use), although I think he would allow me to have it if I really want it.

So wondering if anyone else is on it?

I am T2 diabetic and took Metformin for about 10 years, my observation is that the side effects are directly related to the dose level. At lower doses the side effects for me were very minor, but at higher doses the side effects became a real issue. We all vary so some do not get any side effects at all, others do. There is an extended release version that helps a lot with side effects.

I no longer take metformin and now manage my diabetes with diet and exercise. Interestingly, I was still taking metformin at the time of my diagnosis.

My Blood Glucose is measured by taking blood and doing an HbA1c test, this measures blood sugars over a period of some ( 2 or 3 ) months and is more accurate for most purposes.

Metformin is best started at the lowest dose and built up over time.

Saw my GP again today, and he's let me have metformin.

STAMPEDE dose docs said 850mg, initially once a day, and escalate to twice a day after a month if tolerated well.

My GP said they don't normally prescribe the 850mg dose any more. It's been replaced with a 500mg slow release dose which is less harmful to the stomach, and doesn't generate large fluctuations in level like the 850mg dose did, so that what I've got. Starting with one tablet per day, and I can escalate to two if I want to.

It's not allowed with contrast dyes for CT/MRI scans (they're both quite a load on the kidneys), and having had one of those yesterday, I will wait a day or two more before starting it.

What side effects did you have? GP mentioned it can impact bowel movements, and some people come off it due to that.

My side effects were :- Loose bowels, wind ( bottom burps!), cramping, and a slight nauseous feeling.

They can ease after time and not everyone gets them.

Some foods are best avoided, mainly those that are windy, beans, sprouts etc.

Take care when bending down in company :-0
