Byetta (Exenatide) can lower your blood sugars in addition to metformin. It does not increase your appetite unlike some other anti-diabetics, but must be given by injection and usually causes upset stomach.

Lowers your blood sugar.

alogliptin is a good add-on treatment if your blood sugar is still too high, but you don't want to use an injectable medicine.
