Lifestyle & Tips
- Take acarbose with the first bite of each main meal (breakfast, lunch, and dinner).
- Continue to follow your doctor's recommended diet and exercise plan.
- If you experience low blood sugar (hypoglycemia) while taking acarbose with other diabetes medications (like insulin or sulfonylureas), treat it with pure glucose (dextrose) tablets or gel, not regular table sugar or sugary drinks, as acarbose will block the breakdown of table sugar.
- Be aware that common side effects include gas, bloating, and diarrhea, especially when starting the medication or increasing the dose. These usually lessen over time.

This list is not exhaustive, and it is crucial to discuss all your medications, including prescription and over-the-counter drugs, natural products, and vitamins, with your doctor and pharmacist. They will help you determine if it is safe to take this medication with your other medications and health conditions. Never start, stop, or change the dose of any medication without first consulting your doctor to ensure your safety.
Precautions & Cautions
Monitor your blood sugar levels as directed by your doctor. Additionally, have your blood work checked as recommended by your doctor, and discuss the results with them. Adhere to the diet and exercise plan outlined by your doctor to maintain optimal blood sugar control.
Be aware that stress, such as fever, infection, injury, or surgery, can make it more challenging to manage your blood sugar levels. Changes in physical activity, exercise, or diet can also impact your blood sugar control.

If you are pregnant, planning to become pregnant, or are breastfeeding, consult your doctor to discuss the potential benefits and risks to you and your baby.
Overdose Information
Overdose Symptoms:
- Acute overdose of acarbose is not expected to cause hypoglycemia if not taken with sulfonylureas or insulin. However, it may lead to transient increases in flatulence, diarrhea, and abdominal discomfort.
What to Do:
In case of overdose, contact a poison control center immediately (1-800-222-1222) or seek emergency medical attention. Avoid food or drinks containing carbohydrates for 4-6 hours after an overdose.
Drug Interactions
Moderate Interactions
- Intestinal adsorbents (e.g., charcoal): May reduce the effect of acarbose.
- Digestive enzyme preparations (e.g., amylase, pancreatin): May reduce the effect of acarbose.
- Thiazides, corticosteroids, phenothiazines, thyroid products, estrogens, oral contraceptives, phenytoin, nicotinic acid, sympathomimetics, calcium channel blockers, and isoniazid: May cause hyperglycemia and reduce the glucose-lowering effect of acarbose.
Monitoring
Baseline Monitoring
Rationale: To establish baseline glycemic control.
Timing: Prior to initiation of therapy.
Rationale: To assess renal function, as acarbose is contraindicated in severe renal impairment.
Timing: Prior to initiation of therapy.
Rationale: To establish baseline liver function, as transient elevations have been reported.
Timing: Prior to initiation of therapy.
Routine Monitoring
Frequency: Every 3-6 months
Target: Individualized, typically <7%
Action Threshold: If target not met, consider dose adjustment or additional therapy.
Frequency: Periodically, as needed for dose titration
Target: Individualized, typically <180 mg/dL 1-2 hours post-meal
Action Threshold: If consistently elevated, consider dose adjustment.
Frequency: Every 3 months during the first year of treatment, then periodically (e.g., annually) or as clinically indicated.
Target: Within normal limits
Action Threshold: If persistently elevated, consider dose reduction or discontinuation.
Symptom Monitoring
- Symptoms of hypoglycemia (if used with sulfonylureas or insulin): sweating, tremor, dizziness, confusion, hunger.
- Gastrointestinal side effects: flatulence, diarrhea, abdominal pain/cramping, bloating.
- Symptoms of liver injury: unusual fatigue, dark urine, yellowing of skin/eyes (jaundice), nausea, vomiting, abdominal pain.
Special Patient Groups
Pregnancy
Acarbose is Pregnancy Category B. Studies in animals have shown no evidence of harm to the fetus. However, there are no adequate and well-controlled studies in pregnant women. Acarbose should be used during pregnancy only if clearly needed.
Trimester-Specific Risks:
Lactation
It is not known whether acarbose is excreted in human milk. Due to the potential for adverse effects in nursing infants, a decision should be made whether to discontinue nursing or to discontinue the drug, taking into account the importance of the drug to the mother. Generally not recommended.
Pediatric Use
Safety and effectiveness of acarbose in pediatric patients (under 18 years of age) have not been established. Use is not recommended.
Geriatric Use
No specific dose adjustment is required based on age alone. However, elderly patients may have age-related decline in renal function, which should be assessed before initiating therapy and monitored periodically, as acarbose is contraindicated in severe renal impairment.
Clinical Information
Clinical Pearls
- Acarbose must be taken with the first bite of each main meal to be effective.
- It does not cause hypoglycemia when used as monotherapy, but can increase the risk when combined with insulin or sulfonylureas.
- If hypoglycemia occurs while on acarbose (especially with other antidiabetics), treat with pure glucose (dextrose), not sucrose (table sugar), as acarbose inhibits sucrose breakdown.
- Gastrointestinal side effects (flatulence, diarrhea, abdominal discomfort) are common, especially at the start of therapy or with dose increases, but often improve with continued use and dietary adjustments.
- Liver enzymes should be monitored periodically, especially during the first year of treatment.
Alternative Therapies
- Metformin (Biguanide)
- Sulfonylureas (e.g., Glipizide, Glyburide, Glimepiride)
- Thiazolidinediones (TZDs) (e.g., Pioglitazone, Rosiglitazone)
- DPP-4 Inhibitors (e.g., Sitagliptin, Saxagliptin)
- GLP-1 Receptor Agonists (e.g., Liraglutide, Semaglutide)
- SGLT2 Inhibitors (e.g., Canagliflozin, Dapagliflozin, Empagliflozin)
- Insulin
- Meglitinides (e.g., Repaglinide, Nateglinide)
