Does Metformin Contain Lactose? Could This Be Triggering My Lactose Intolerance?

The metformin seems to create the same problems as my lactose intolerance, but on a much greater scale. An article I read about Metformin mentioned lactic acidosis, which got me to wondering if Metformin contains lactose or something similar. The obvious next question is whether or not there is a drug with similar efficacy, without that particular problem.

Answer

Hi Zinnia,

Lactic Acidosis doesn't have anything to do with lactose or being lactose intolerant. Lactic Acidosis is a condition where the body creates more lactic acid than it can dispose of. The metformin can sometimes hamper renal/kidney function, making it more difficult for the body to excrete the lactic acid causing the condition.

I don't see anything to suggest that the metformin is causing a lactose intolerance, but the side effects can mimic lactose intolerance with regard to gastro issues, diarrhea, IBS, gas, etc. You can read more about Metformin (generic for Glucophage) here in the drugs database.

Hope this helps! Take care and stay in touch!
