I was wondering if insulin is better for you than taking Metformin to control diabetes? I was wondering that because I don't like the taste of the pill and it goes right through me all the time after I eat and take it.

Metformin and insulin work differently. Metformin helps the liver make less glucose and helps the cells use insulin more effectively. Insulin, on the other hand, is a hormone that lowers blood glucose. Metformin is used for people with type 2 diabetes and can be used in addition to insulin. Most who take metformin will stay on the drug even after starting insulin. You are right that the metformin pills can taste funny and also can be hard to swallow. There is a liquid version of metformin called Riomet that may be more agreeable to you, but this particular medicine is usually reserved for people who have trouble swallowing pills. You also state that the metformin “goes right through me.” The extended release versions of metformin can have less stomach upset associated with them and may taste differently as well. Trying an extended release version of metformin, such as metformin ER or Glumetza, may be a topic you can discuss at your next diabetes visit with your primary care provider.

I was diagnose in 2009, and I am taking Metformin since then. How long I suppose to use this drug?…
Someone knows what are the "typical" side effects of it?
Thanks a lot in advance to whom respond.
Peace and health for everyone!

I just started on insulin, but am still taking my oral meds. I notice that the orals don't really do anything and the insulin seems to be finally helping me out. Thank goodness. I am hoping to be taken off at least my glypizide at my next visit.

I'm type 2 13 yrs now.
Metformin has been in my meds for years off and on.
Metformin did in fact hurt my kidneys although other meds I took did not help either.

Had an ultrasound last week. I'm seeing a renal doctor this week to have biopsys done on my Kidneys.One Kidney has a Cyst. Again All Diabetics are different in their daily walk.
keep in touch so we can grow together :)

PS Metformin can be a laxative to the system. :)
