Metformin is a drug prescribed to help treat diabetes type 2. Patients with Type 2 Diabetes can not control the level of sugar in their blood stream without drugs, sometimes including insulin, because the body lacks the ability to properly process the insulin produced by the body naturally.

Metformin acts by reducing the amount of glucose in the bloodstream and help the body to respond appropriately to the presence of insulin. It is usually taken as a tablet, with the option of extended release available that allow patients to take a single dose instead of multiple smaller doses.

Diabetes, both type 1 and type 2, usually covered by standard insurance policies. However, it can be seen as a pre-existing condition when the patient is issued a new policy. That is, however, unless he can provide proof of continuous coverage during the previous 12 months.

If the diagnosis of diabetes was determined to be a pre-existing condition and therefore subject to the waiting period, patients could find themselves without coverage for their conditions and care for up to 18 months. During this time, patients are left to pay out of pocket for her diabetes care.

Similar situations arose for elderly patients on Medicare. When a patient falls into the "donut hole" associated with the Medicare health insurance, medications such as metformin should be paid for out of pocket to resume coverage. This can put an unnecessary financial burden on elderly patients who often live on a fixed income.
