About Precose
Generic Precose (Acarbose) is a prescription-only oral medication used to improve blood-sugar control in adults with type 2 diabetes. It belongs to the class of α-glucosidase inhibitors, which act locally in the intestine to slow the breakdown of complex carbohydrates. In Australia, the Therapeutic Goods Administration (TGA) approved acarbose in 1999, and it is available in 25 mg and 50 mg tablets. Alongside diet and exercise, it helps blunt post-prandial glucose spikes, a key target in modern diabetes management.
What is Generic Precose (Acarbose)?
Generic Precose (Acarbose) is the generic form of the branded α-glucosidase inhibitor acarbose. The drug works in the gastrointestinal tract rather than entering systemic circulation in significant amounts. It is regulated by the TGA as a Schedule 4 prescription product, meaning it can be dispensed only with a valid medical prescription. The therapeutic aim is to lower post-meal blood-glucose excursions in people with type 2 diabetes mellitus (T2DM). While its primary indication is T2DM, clinicians sometimes consider it for patients who experience pronounced post-prandial hyperglycaemia despite other oral agents.
How Precose Works
Acarbose competitively inhibits intestinal α-glucosidases-enzymes that catalyse the final step of carbohydrate digestion. By blocking these enzymes, the drug delays the hydrolysis of disaccharides and oligosaccharides into absorbable glucose. The result is a slower and reduced rise in blood glucose after meals.
Pharmacokinetic studies show that less than 2 % of the dose is absorbed systemically; most of the drug remains in the lumen and is metabolised by intestinal bacteria into inactive metabolites. Peak enzymatic inhibition occurs within 30 minutes to one hour after ingestion, aligning with typical meal timing. Because systemic exposure is minimal, hepatic metabolism plays a negligible role, and the drug’s half-life is not clinically relevant. This local action accounts for the gastrointestinal side-effect profile, as unabsorbed carbohydrate fermentation leads to gas production.
Why Precose is Used for Diabetes Conditions
-
Post-prandial glucose control • Acarbose directly reduces the rate at which glucose enters the bloodstream after carbs, flattening the glucose curve. • Clinical trials (e.g., the STOP-NIDDM study) demonstrated a .5-% to .8 % reduction in HbA1c when added to metformin or sulfonylureas.
-
Complement to other agents • Because it acts independently of insulin secretion, acarbose can be combined with insulin-sensitising drugs (metformin) or insulin secretagogues (sulfonylureas) without overlapping mechanisms.
-
First-line or add-on therapy • Australian diabetes guidelines list α-glucosidase inhibitors as second-line options after metformin failure, especially when post-prandial spikes dominate the glycaemic profile.
-
Weight-neutral profile • Unlike some sulfonylureas or thiazolidinediones, acarbose does not cause weight gain; modest weight loss has been noted in some patients, likely due to reduced caloric absorption.
-
Cost-effective generic • Generic Precose offers the same bio-equivalence as the branded product at a lower price, making it accessible for patients with limited insurance coverage.
Off-Label and Investigational Uses of Precose
Evidence from small prospective studies suggests acarbose may attenuate the progression from impaired glucose tolerance to overt diabetes, particularly in Asian populations where carbohydrate intake is high. However, the Australian TGA has not approved this indication, and the data are limited to short-term trials. Off-label use should only be considered under the supervision of a qualified healthcare provider.
Is Precose Right for You?
Precose suits adults with type 2 diabetes who need better post-meal glucose control and are not achieving targets with metformin alone. Ideal candidates are those with:
- Predominant post-prandial hyperglycaemia.
- Normal renal function (creatinine clearance ≥ 60 mL/min); dose reduction may be needed in moderate renal impairment.
- No history of chronic liver disease, as rare hepatic enzyme elevations have been reported.
Pregnancy and breastfeeding are contraindicated due to insufficient safety data (Category C). Elderly patients may experience intensified gastrointestinal effects, so a slower titration (starting at 25 mg three times daily) is advisable. Individuals with inflammatory bowel disease or a history of intestinal obstruction should avoid acarbose because it can exacerbate symptoms.
Taking Precose Effectively
- Timing: Take one tablet with the first bite of each main carbohydrate-containing meal (usually three times daily).
- Food interactions: The drug’s efficacy depends on the presence of carbohydrates; taking it with a non-carbohydrate snack reduces its benefit.
- Missed dose: If you forget a dose, take it as soon as you remember only if a meal is still upcoming; otherwise, skip it and resume the regular schedule.
- Travel tips: Carry tablets in the original packaging to avoid customs issues; keep them at room temperature, away from moisture.
- Dose titration: Begin with 25 mg TID; after one to two weeks, increase to 50 mg TID if tolerated, aiming for a maximum of 100 mg TID based on glycaemic response.
Understanding Side Effects and How to Manage Them
The most common adverse events are gastrointestinal, directly linked to the drug’s mechanism of carbohydrate fermentation:
-
Flatulence and abdominal distension - Occur as bacterial gases accumulate. Management: Start with a low dose, increase gradually, and consider a low-FODMAP diet to reduce gas-producing substrates.
-
Diarrhoea - Result from unabsorbed carbohydrates drawing water into the lumen. Management: Ensure adequate hydration, and if diarrhoea persists beyond two weeks, consult a clinician for possible dose reduction.
-
Upper abdominal pain - May be mitigated by taking the tablet with water and the first bite of the meal, rather than after a large carbohydrate load.
Rare but serious side effects include hepatic enzyme elevations and severe hypoglycaemia when combined with insulin or sulfonylureas. Routine liver function testing is recommended during the initial months of therapy. If you experience jaundice, dark urine, or persistent fatigue, seek immediate medical attention.

Frequently Asked Questions
-
What should I eat when taking Precose? Take the tablet with the first bite of a carbohydrate-rich meal. Meals low in carbs provide little benefit, as the drug’s action depends on the presence of digestible sugars.
-
Can Precose be used with insulin? Yes, but dosage of insulin may need adjustment because Precose blunts post-prandial glucose peaks, increasing the risk of hypoglycaemia if insulin doses remain unchanged.
-
Why do I experience gas after starting Precose? The inhibition of carbohydrate breakdown leads to increased fermentation by intestinal bacteria, producing gas. This effect often diminishes as the gut microbiota adapts.
-
Is there a difference between generic Precose and the brand? Generic Precose contains the same active ingredient, acarbose, at identical strength and is required to demonstrate bio-equivalence. The therapeutic outcome is therefore comparable.
-
How often should liver function be monitored? Baseline liver enzymes are recommended before initiating therapy, followed by repeat testing after 2-3 months, especially if you are taking other hepatotoxic drugs.
-
Can I take Precose if I have a history of ulcer disease? Acarbose does not directly irritate the gastric lining, but the increased gas and bloating may exacerbate discomfort. Discuss your ulcer history with a clinician before starting.
-
What happens if I miss a dose? Skip the missed tablet if the next meal is more than an hour away; resume the regular schedule with the next meal. Do not double-dose to compensate.
-
Is Precose safe for people over 75 years old? Elderly patients often tolerate lower initial doses better. Starting at 25 mg three times daily and titrating slowly can minimise gastrointestinal side effects.
-
Can Precose be used in type 1 diabetes? It is not approved for type 1 diabetes because the primary pathology involves insulin deficiency rather than post-prandial carbohydrate absorption.
-
How does Precose compare to DPP-4 inhibitors? DPP-4 inhibitors enhance endogenous incretin levels, affecting fasting and post-prandial glucose. Acarbose solely targets carbohydrate digestion, making it a complementary option when post-prandial spikes dominate.
-
Will Precose affect my cholesterol levels? Some studies have observed modest reductions in LDL cholesterol, likely secondary to improved glycaemic control, but cholesterol management should remain independent of acarbose therapy.
