⚡ Quick Answer — What is Cyblex MV?
Cyblex MV is a triple-drug fixed-dose combination of metformin, gliclazide and voglibose (Metformin 500 mg + Gliclazide 80 mg + Voglibose 0.2 mg) used for type 2 diabetes not controlled on dual therapy. Three complementary mechanisms in a single tablet: metformin reduces hepatic glucose production; gliclazide (a second-generation sulfonylurea) stimulates insulin release; voglibose slows intestinal carbohydrate absorption to blunt post-meal spikes. Typical HbA1c reduction: 2.0–2.5 points. Usual dose: one tablet 1–3 times daily with the first bite of each main meal. Side-effect profile combines hypoglycaemia risk (gliclazide), GI flatulence/bloating (voglibose), and metformin GI upset. Hypoglycaemia rescue requires glucose (dextrose) tablets, not table sugar (voglibose blocks sucrose breakdown). Avoid in type 1 diabetes, eGFR < 30, IBD, severe hepatic impairment, and sulfa allergy.

What Is Cyblex MV?
Cyblex MV is an oral fixed-dose combination tablet containing three active antidiabetic ingredients: metformin, gliclazide and voglibose (Metformin 500 mg + Gliclazide 80 mg + Voglibose 0.2 mg). Manufactured by WHO-GMP certified manufacturer. Available in packs of 30, 60, 90 or 180 tablets. It is used in adults with type 2 diabetes when dual therapy is not enough and the clinician wants to intensify oral treatment before starting insulin.
The three-way combination is especially useful in people with a predominantly carbohydrate-rich diet (Asian populations) where post-meal glucose spikes are a major driver of HbA1c.
How Does Cyblex MV Work?
Cyblex MV targets hyperglycaemia through three completely separate mechanisms:
- Metformin — reduces hepatic glucose production (activates AMPK), improves insulin sensitivity in muscle/fat, slightly slows intestinal glucose absorption. Does not cause hypoglycaemia on its own.
- Gliclazide — a second-generation sulfonylurea. Closes KATP channels on pancreatic beta cells, triggering insulin release. Gliclazide has the best cardiovascular-safety profile in its class (ADVANCE trial).
- Voglibose — an alpha-glucosidase inhibitor that slows carbohydrate breakdown in the gut, reducing the post-meal glucose spike. Acts locally in the gut lumen; minimal systemic effect.
Combined HbA1c reduction: 2.0–2.5 percentage points. The combination covers fasting, post-meal, and overall insulin-resistance contributions to hyperglycaemia in one tablet.
Dosage and Administration
Usual dose: one tablet taken with the first bite of each main meal (once, twice, or three times daily depending on prior regimen and HbA1c target).
- Take with the first bite — voglibose must be ingested with food to act; gliclazide needs a meal to avoid hypoglycaemia; metformin is best tolerated with food.
- Skip the dose if you skip the meal — especially important because of the gliclazide component.
- Hypoglycaemia rescue: always use pure glucose (dextrose) tablets or gel, not table sugar or fruit juice — voglibose blocks sucrose breakdown in the gut.
- Renal dosing: avoid if eGFR < 30. Reduce dose if eGFR 30–45.
- Hold for IV contrast, surgery, or acute illness with dehydration.
- Monitor glucose, HbA1c, weight, renal function, and vitamin B12 annually.
Side Effects
From metformin (first 1–2 weeks): diarrhoea, nausea, abdominal cramps, metallic taste.
From gliclazide:
- Hypoglycaemia — gliclazide has the lowest hypoglycaemia risk among sulfonylureas, but it is still possible.
- Modest weight gain (1–2 kg)
- Occasional skin rash
From voglibose: flatulence, bloating, soft stools, diarrhoea — usually improves with slow titration.
Uncommon but serious: lactic acidosis (metformin) — very rare, almost always in AKI/sepsis/hypoxia; severe or prolonged hypoglycaemia; hepatic-enzyme elevation; rare haemolytic anaemia in G6PD deficiency.
Drug Interactions
- Raise hypoglycaemia risk: insulin, other antidiabetics, alcohol, trimethoprim/sulfamethoxazole, fluconazole, clarithromycin, ACE inhibitors, high-dose salicylates, non-selective beta-blockers (also mask symptoms).
- IV iodinated contrast — hold pre- and post-procedure if eGFR < 60.
- Carbonic anhydrase inhibitors (acetazolamide, topiramate) — raise lactic acidosis risk.
- Cationic drugs (cimetidine, dolutegravir, ranolazine) — raise metformin levels.
- Digestive enzyme preparations — counteract voglibose; avoid.
- Corticosteroids, thiazides, thyroid hormones, oral contraceptives, atypical antipsychotics, phenytoin, rifampicin — may reduce glucose-lowering effect.
Who Should Not Take Cyblex MV?
- Type 1 diabetes mellitus or diabetic ketoacidosis
- Severe renal impairment (eGFR < 30)
- Severe hepatic impairment
- Inflammatory bowel disease or chronic intestinal obstruction
- Sulfonamide (sulfa) allergy
- Acute illness with tissue-hypoxia risk
- Pregnancy and breastfeeding
- Known hypersensitivity to any component
Storage
Store Cyblex MV below 25°C in a dry place. Keep out of reach of children.
Frequently Asked Questions
Why a triple-drug diabetes tablet?
To simplify the regimen. Patients needing metformin + sulfonylurea + alpha-glucosidase inhibitor would otherwise take three separate tablets at each meal. Combining them into one tablet improves adherence and reduces pill burden without changing the clinical effect.
If I get low blood sugar, can I just eat a sweet?
No — take pure glucose (dextrose) tablets or gel. Because Cyblex MV contains voglibose, the alpha-glucosidase inhibitor blocks the breakdown of sucrose (table sugar) and many other complex carbohydrates, so they work too slowly for a hypo. Glucose itself is absorbed directly and works within minutes.
Does Cyblex MV cause weight gain?
Modest 1–2 kg, driven by the gliclazide component. Metformin and voglibose are weight-neutral or very slightly weight-reducing, so the net effect is usually less than sulfonylurea monotherapy.
Can I drink alcohol while taking Cyblex MV?
Moderate alcohol with food is usually safe. Avoid binge drinking — raises hypoglycaemia risk (gliclazide) and lactic acidosis risk (metformin).
Should I switch to insulin?
A decision for you and your prescriber. Insulin is essential once beta-cell function is severely reduced but has its own risks (hypoglycaemia, weight gain, injections). Triple oral therapy like Cyblex MV is often tried first in motivated patients with residual beta-cell function.
Where can I buy Cyblex MV online?
