Precose
Precose (acarbose) is an alpha-glucosidase inhibitor used in the management of type 2 diabetes mellitus. It works by slowing down the digestion and absorption of carbohydrates in the intestines, leading to a reduction in postprandial (after meal) blood glucose levels. This medication is often used in combination with other antidiabetic agents when diet and exercise alone are not sufficient to control blood sugar levels.

Frequently Asked Questions
How quickly does Precose start to work?
Acarbose begins to work within a few hours after taking it with a meal, but it may take several weeks to see the full effect on blood sugar control.
Can I stop taking Precose suddenly?
It is generally safe to stop taking Precose without tapering, but consult your healthcare provider if you have concerns about your diabetes management.
Are there any specific dietary restrictions while taking Precose?
There are no specific dietary restrictions, but maintaining a balanced diet with controlled carbohydrate intake is important for effective diabetes management.
What should I do if I miss a dose of Precose?
If you miss a dose, take it with the next meal. If it's almost time for your next dose, skip the missed dose and continue with your regular schedule. Do not double up on doses.
Is Precose safe for long-term use?
Precose can be used long-term under medical supervision, but regular monitoring of blood glucose levels and liver function is essential to assess effectiveness and any potential side effects.
Comprehensive Drug Guide
How Does Precose Work?
Acarbose works by inhibiting the enzymes (alpha-glucosidases) in the intestines that are responsible for breaking down complex carbohydrates into simple sugars. By delaying carbohydrate absorption, it reduces the spike in blood glucose levels that typically occurs after meals. This helps to improve glycemic control in patients with type 2 diabetes.
Common Dosages
- Tablets: 25 mg, 50 mg, and 100 mg
Typical Dosing
- The usual starting dose is 25 mg taken orally at the start of each meal. If tolerated, the dose may be gradually increased to a maximum of 300 mg per day, divided among meals.
Typical Dosing
FDA Approved Indications
- Management of type 2 diabetes mellitus as an adjunct to diet and exercise.
Who Shouldn't Take Precose?
- Known hypersensitivity to acarbose or any of its components
- Inflammatory bowel disease or bowel obstruction
- Severe renal impairment
- Cirrhosis or other severe liver diseases
Advice From The Pharmacist
- Take Precose with the first bite of each meal to maximize its effectiveness in controlling postprandial blood sugar levels.
- Monitor blood glucose levels regularly to assess the effectiveness of the treatment.
- Report any gastrointestinal side effects, such as significant bloating or diarrhea, to your healthcare provider, as these can be common with acarbose.
Side Effects of Precose
Common Side Effects
- Flatulence
- Diarrhea
- Abdominal pain or discomfort
- Nausea
Uncommon/Severe Side Effects
- Liver enzyme elevations
- Severe allergic reactions (such as rash, itching, or difficulty breathing)
Risks and Warnings of Precose
- Gastrointestinal Effects: Acarbose can cause significant gastrointestinal side effects; patients should be advised that these effects often decrease with continued use.
- Hypoglycemia Risk: While acarbose alone typically does not cause hypoglycemia, it may contribute to hypoglycemia when used with other antidiabetic medications. In the case of hypoglycemia, glucose should be used to treat it instead of sucrose, as acarbose may delay the absorption of sucrose.
Interactions with Precose
Common Drug Interactions
- Antidiabetic Agents: Caution is advised when used in combination with other medications that can lower blood sugar levels, as this may increase the risk of hypoglycemia.
- Digestive Enzyme Supplements: Use with caution, as digestive enzymes may interfere with the action of acarbose.
Alternatives to Precose
- Other Oral Antidiabetic Medications: Such as metformin, sulfonylureas, or DPP-4 inhibitors for managing type 2 diabetes.
- GLP-1 Receptor Agonists: Such as liraglutide, which can also help control blood sugar levels.
