How does this medication work? What will it do for me?
Repaglinide belongs to the class of medications called antidiabetes agents. It is an oral hypoglycemic (lowering of blood sugar) medication used by people with type 2 diabetes, along with proper diet and exercise, for the control of blood sugar. It is used when diet, exercise, and weight reduction alone have not been found to control blood sugar well enough.
Repaglinide may also be used in combination with metformin or rosiglitazone, two other medications that lower blood sugar, when medication (in addition to diet, exercise, and weight reduction) does not control blood sugar well enough on its own. Repaglinide helps to control blood sugar by increasing the amount of insulin released by the pancreas.

How should I use this medication?
The usual dose of repaglinide is based on response to the medication, but is usually started at 0.5 mg. It can be taken either immediately before a meal or up to 30 minutes before a meal. The dose is increased by your doctor based on your response to the medication. The maximum daily dose is 16 mg. Repaglinide may be used along with other medications that reduce blood sugar if one medication is not enough to reduce blood sugar levels to the desired range.
Repaglinide should only be taken with meals. Because it works by increasing the release of insulin into the blood, if a meal is delayed, wait until you are starting to eat before taking the medication. If you skip a meal, do not take repaglinide. Wait until your next meal to take a dose.
