Precose, also known as Acarbose, is used in conjunction with a proper diet and exercise program to control high blood sugar in individuals with type 2 diabetes. 

The focus on controlling high blood sugar is crucial for preventing a range of serious complications associated with diabetes, including kidney damage, blindness, nerve problems, loss of limbs, and sexual function problems.

Acarbose works in the intestines to slow the breakdown and absorption of carbohydrates from the foods consumed. This effect helps to moderate the rise in blood sugar levels after a meal, contributing to the overall control of blood sugar throughout the day and after eating.


  • Take Precose exactly as prescribed by your healthcare provider, typically 3 times daily with the first bite of your main meals.
  • Follow your healthcare provider's instructions carefully, especially regarding the starting dose and any gradual increases.
  • Take Precose consistently at the same times each day to maximize its effectiveness.
  • Inform your healthcare provider if your blood sugar control improves or worsens while taking Precose.


  • Don't take Precose at any other time than with the first bite of a meal.
  • Don't skip doses or take more medication than prescribed.
  • Don't adjust your dosage without consulting your healthcare provider.

Common side effects:

  • Stomach discomfort
  • Gas
  • Bloating
  • Mild diarrhea

  • Unusual bleeding (nose, mouth, vagina, or rectum)
  • Purple or red pinpoint spots under the skin
  • Decreases in hematocrit, calcium, or vitamin B6 levels

  • Severe gastrointestinal side effects that may progress to intestinal obstruction caused by paralysis of the intestinal muscles (paralytic ileus)

This is not an exhaustive list, and other side effects may occur. If you experience any unusual or severe side effects while taking Precose,  contact your healthcare provider for medical advice.

Tell your healthcare provider if you have allergies to Precose or any ingredients in Precose.

Inform your healthcare provider about your medical history, especially intestine/bowel problems, kidney problems, or liver disease.

Precose may cause blurred vision, dizziness, or drowsiness. Avoid activities requiring alertness until you feel safe.

Limit alcohol while taking Precose because it can increase your risk of low blood sugar.

Stress can make it harder to control your blood sugar. Consult your healthcare provider if you experience stress as your treatment plan may need adjustment. Tell your healthcare provider about all medications you take before surgery.

Precose should only be used during pregnancy when clearly needed. Discuss the risks and benefits with your healthcare provider.

Pregnancy may affect your diabetes management. Discuss a plan with your healthcare provider. It is unknown if Precose passes into breast milk. Consult your healthcare provider before breastfeeding.

Precose can interact with other medications. Tell your healthcare provider about all medications you take, including prescription/nonprescription drugs and herbal products.

Some medications that may interact with Precose include charcoal products, digestive enzyme products, pramlintide, beta-blocker medications, and glaucoma eye drops.

Regularly check your blood sugar as directed and share the results with your healthcare provider. Tell your healthcare provider right away if you have symptoms of high or low blood sugar. Your healthcare provider may need to adjust your medication, exercise program, or diet.
