What is Xenglu Met 12.5/850mg Tablet?
Xenglu Met 12.5/850mg combines Empagliflozin 12.5mg and Metformin Hydrochloride 850mg — two complementary diabetes medicines working through entirely different mechanisms in a single tablet. Empagliflozin removes excess glucose through the kidneys by blocking SGLT2 transporters, while Metformin reduces the liver's excess glucose production and improves insulin sensitivity. Together they provide stronger blood sugar control than either medicine alone, alongside clinically proven cardiovascular and kidney-protective benefits — making this combination particularly valuable for Type 2 diabetes patients with heart disease or at risk of kidney complications.
What is Xenglu Met 12.5/850mg Used For?
- Type 2 diabetes mellitus — improving blood sugar control when single-agent therapy is insufficient (ذیابیطس)
- Cardiovascular death risk reduction — Empagliflozin component reduces risk of cardiovascular death in patients with established heart disease
- Kidney protection — slowing progression of diabetic kidney disease under medical supervision
- Weight management — Empagliflozin-associated urinary glucose excretion contributes to modest weight reduction
- Step-up combination therapy — for patients requiring both SGLT2 inhibition and Metformin in one tablet
How Does Xenglu Met 12.5/850mg Work?
Empagliflozin 12.5mg — SGLT2 Inhibitor: Blocks SGLT2 transporters in the kidney's proximal tubule, preventing glucose reabsorption back into the bloodstream. This causes excess glucose to be excreted in urine daily — lowering blood sugar independently of insulin. The accompanying fluid and sodium excretion also produces modest reductions in blood pressure and body weight, contributing to cardiovascular and kidney-protective benefits observed in clinical trials.
Metformin Hydrochloride 850mg — Biguanide: Reduces the liver's excessive glucose production — the primary driver of elevated fasting blood sugar in Type 2 diabetes. It also improves peripheral insulin sensitivity in muscles, helping cells absorb and use glucose more effectively throughout the day. Metformin does not stimulate insulin production, keeping hypoglycaemia risk low when used without insulin or sulphonylureas.
Combined Effect: Empagliflozin addresses post-meal and overall glucose load through urinary excretion while Metformin controls fasting glucose through liver suppression and insulin sensitisation — providing comprehensive blood sugar management with added heart and kidney protection.
Dosage and Administration
⚠️ Take exactly as prescribed alongside a diabetes-appropriate diet and regular exercise. Never stop without medical advice.
| Indication | Usual Adult Dose | Frequency |
|---|---|---|
| Type 2 diabetes combination therapy | 1 tablet (12.5mg/850mg) | Twice daily with meals |
- Always take with meals to minimise Metformin-related stomach side effects
- Swallow whole with a full glass of water
- Maintain adequate fluid intake throughout the day — Empagliflozin increases fluid loss through urination
- Regular HbA1c, kidney function, and Vitamin B12 monitoring required during treatment
Active Ingredients
| Ingredient | Strength per Tablet |
|---|---|
| Empagliflozin | 12.5mg |
| Metformin Hydrochloride | 850mg |
Who Should NOT Take Xenglu Met 12.5/850mg?
- Type 1 diabetes — not indicated; increases diabetic ketoacidosis risk
- Severe kidney disease (eGFR below 30) — both components are contraindicated
- Severe liver disease or history of lactic acidosis
- Known allergy to Empagliflozin, Metformin, or any SGLT2 inhibitor
- Recurrent urinary tract or genital fungal infections
- Pregnancy or breastfeeding — avoid; consult doctor immediately
Consult your doctor before use if you have: moderate kidney disease, low blood pressure, heart failure, history of recurrent UTIs or genital infections, or are scheduled for surgery or contrast imaging.
Side Effects
Common:
- Nausea, stomach discomfort, or diarrhoea — reduced by always taking with food
- Genital yeast infections (thrush) — due to increased urinary glucose from Empagliflozin (فنگل انفیکشن)
- Urinary tract infections — increased urinary glucose raises infection risk
- Increased urination — expected effect of urinary glucose excretion
- Metallic taste in the mouth — common Metformin effect, usually temporary
Serious — seek medical attention immediately:
- Lactic acidosis — rare but life-threatening Metformin complication; muscle pain, weakness, difficulty breathing, stomach pain (یہ طبی ہنگامی صورتحال ہے)
- Diabetic ketoacidosis (DKA) — nausea, vomiting, abdominal pain, difficulty breathing — can occur even with near-normal blood sugar
- Severe dehydration — dizziness, fainting, markedly reduced urination
- Fournier's gangrene — rare but serious genital area infection requiring emergency care
- Severe allergic reaction — facial swelling, difficulty breathing, widespread rash
Drug Interactions
| Medicine | Interaction |
|---|---|
| Insulin / Sulphonylureas (e.g., Glibenclamide) | Increased hypoglycaemia risk — dose reduction may be needed |
| Iodinated contrast media (X-ray dye) | Metformin must be stopped before and 48 hours after contrast procedures — kidney failure risk |
| Diuretics (e.g., Furosemide) | Combined fluid loss increases dehydration and low blood pressure risk |
| Alcohol (شراب) | Increases lactic acidosis risk from Metformin — avoid excessive alcohol |
| Corticosteroids | Raise blood sugar and reduce effectiveness of diabetes medicines |
| Antihypertensives | Additive blood pressure lowering — monitor for hypotension |
Storage Instructions

Frequently Asked Questions (FAQs)
Q: Why does Xenglu Met contain 12.5mg Empagliflozin instead of the standard 10mg or 25mg? The 12.5mg dose is specifically formulated for combination tablets — delivering effective SGLT2 inhibition at a dose optimised for twice-daily use alongside Metformin, providing consistent coverage throughout the day.
Q: Can Xenglu Met 12.5/850mg cause low blood sugar on its own? No — neither Empagliflozin nor Metformin causes hypoglycaemia independently. The risk increases only when this combination is used alongside insulin or sulphonylurea medicines.
Q: Should I stop Xenglu Met before surgery or a contrast scan? Yes — stop at least 3 days before planned surgery and before any contrast imaging procedure. Restart only after kidney function is confirmed normal and your doctor advises it is safe to do so.
Q: What are the warning signs of diabetic ketoacidosis I must watch for? Nausea, vomiting, stomach pain, extreme tiredness, and difficulty breathing — stop the medicine immediately and go to the nearest emergency department if these symptoms develop.
