I also have loss of taste and no medical problems and take Metformin and sometimes I have almost no taste. As I'm losing weight my dosage is suppose to go so that eventually if I can get where I don't need it anymore I will see if my taste comes back. I do understand this process will take a year, but I'm patient as I have had the loss of taste for longer than that, so I guess I will just have to wait to see if the drug Metformin is the cause of my taste loss unless you would have another suggestion as to why my taste is half to three quarters of what it used to be since I started taking the medicine.View Thread
