The diabetes drug, Januvia, works by lowering one's blood sugar. I have used it myself to treat my Type 2 Diabetes. It worked well in lowering my blood sugar numbers, though it often gave me a stomache ache. Januvia is not for people with Type 1 diabetes. This pill can be split with a pill cutter and taken in half doses with no reprecussions. Sometimes medication will be given lower doses if blood sugar levels regularly drop too low. Half doses might be a good solution to that problem. Because Januvia does not come in an extended release form and is absorbed all at once, the pill does not need to remain intact.
