It is generally recommended that people not use metformin and alcohol at the same time. Taking metformin and alcohol together can increase your risk of developing a life-threatening condition called lactic acidosis. However, drinking small amounts of alcohol should not be a problem for most people taking the medication. There is no risk of a false positive alcohol test due to metformin however. Hope this helps
can the combination of the following drugs cause a false positive drug test for alcohol:
Lisinopril, Fluoxetine,Simvastatin, Isosorb, Metformin, Atenol, Amlodipine and insulin?
what if you added promethazine to the mix?
