Precose (Acarbose)

Precose is used for treating type 2 diabetes in adults whose diabetes cannot be managed with diet alone. Precose may be used alone, in combination with other oral diabetes medicines, or with insulin.

Use Precose as directed by your doctor. Check the label on the medicine for exact dosing instructions.

Take Precose by mouth with food.

If you also take charcoal or digestive enzyme preparations, do not take them within 2 to 4 hours before after taking Precose . Check with your doctor if you have questions.

Temporary insulin therapy may be necessary during stressful periods (such as fever, trauma, infection, or surgery).
