Hi
@titanmuse. I've given pioglitazone a whirl for a few months, and found it didn't have any affect on my blood glucose, sadly, so did not warrent the potential side effects, which, like for you, I found a bit daunting!
This was very disappointing for me as I had high hopes for a drug that apparently sensitizers the cells to one's own insulin, if one, like me, is producing plenty of insulin oneself. (But am obviously highly insulin resistant.)
I have since read that one should give this drug quite a long period to start working, as in six months!(I can't remember where I read this - on some medications website. ) I may give it another go in combination with a drug I am on that has some effect, mild, but some - vildagliptin.
I think with all potential side effects one needs to look at one's physical cons and pros? Which is what your doctor and 'diabetes team' ought to be doing, and perhaps do? Hopefully! (I have not had this experience apart from my trusty GP.) How vulnerable are you to bone fractures/osteoporosis for instance? Cardio vascular problems? And conversely - how resiliant? This is what I did when looking at those scary potential side effects. As it was, I didn't have any, except one of those strange vision experiences in the wee hours of a morning. Which was a bit scary for sure.
But most hopefully, you have a good relationship with your GP or diabetes team member/s and can discuss your fears and hopefully be reassured by them?
You could try going through each potential side effect with your GP/prescribing medical professional, and hear what they say, considering your own health and diabetes presentation, is what I suggest.
