Ah ha!!! So there is another Januvia user in the tudiabetes community. In answer to your question “does Januvia cause beta cell exhaustion?”: I asked the same question when my endocrinologist recommended that I switch from Levimer to Januvia. (Note: I hesitated starting Januvia. I didn’t take any medication for over a month after stopping Levimer but couldn’t control my diabetes with exercise and diet alone. As you probably know, Januvia is a relatively new drug. I believe drugs can be just as–or more–dangerous than the diseases they address; to me, anything that can be done to avoid a prescription drug is preferable.)
My doctor pointed out that in an animal study, Januvia actually improved beta cell function. However, considering info received from this website after I’d already started Januvia, apparently, my doctor is parroting Januvia manufacturer propaganda.
Nevertheless, I’ve not had any side effects on Januvia; my fasting and after meal blood sugars are lower.
So I too have gotten yes and no in answer to the question of whether Januvia “stimulates and improves beta cells function” and I too would appreciate more input about Januvia. I’m seriously considering info about Januvia that Jenny, a member of this community, kindly provided me in the form of links. I’d like to be a better informed patient at my next endo appointment in mid-May. In the meantime, instead of getting a 90-day prescription filled today, I’ve decided to get a prescription filled for a free 30-day trial supply of Januvia (manufacturer voucher)–in case there’s a safer option open to me regarding diabetes treatment.
Best regards, Lucy
