Many medications prescribed for diabetes can also help with other conditions. For example, statins, which are primarily used to lower cholesterol, are recommended for nearly all patients with type 2 diabetes and at least one heart disease risk factor. They may also reduce the risk of bone fractures in older women. Diuretics, used to treat high blood pressure, are believed to reduce the risk of Alzheimer's disease. Additionally, the oral diabetes medicine Avandia may improve memory and thinking ability in people with mild Alzheimer's. It's important to always consult your doctor before using any medication for an off-label purpose.
