Question: Has anyone noticed one brand of generic Metformin being less effective than another brand?
For the last 2 months, my blood sugar has been running about 30 points higher than usual with some spiky behavior I had not previously seen. I use a Free Style Libre and have had predictable readings for a few years. This is definitely out of the norm.
Took action to further reduce carbs & calories, lost 4 pounds, and no improvement. Changed sensor and no improvement. It certainly possible that this is age-related, but seems very sudden.
Last night I realized that my pharmacist filled my last Metformin prescription (short-acting) with a different brand about 2 MONTHS AGO. The new manufacturer is Asceno. At the time, I noticed the different tablet shape and also that this version has the unfortunate “fishy” order. So . . .
Could Asceno Metformin not be working as well as my previous brand? Is this possible? Has anyone heard of such a thing? I plan to talk with the pharmacist on Tuesday, but would love to hear from you guys if there is any wisdom out there. I will probably insist on swapping for a different brand just to see what happens.
Thanks so much!
