What is Sitaglu Met 50/1000mg Tablet?
Sitaglu Met 50/1000mg is the highest-Metformin-strength formulation of the Sitagliptin-Metformin combination — prescribed when maximum Metformin dosing is required alongside Sitagliptin for adequate blood sugar control. It contains Sitagliptin 50mg to enhance the body's natural post-meal insulin response and Metformin Hydrochloride 1000mg — the standard full therapeutic dose of Metformin — to provide maximum suppression of the liver's excess glucose production. This formulation is typically prescribed for patients with Type 2 diabetes requiring the strongest available Metformin effect combined with DPP-4 inhibition in a single convenient tablet.
What is Sitaglu Met 50/1000mg Used For?
- Type 2 diabetes mellitus — blood sugar control when lower-strength combinations or single agents are insufficient (ذیابیطس)
- Maximum Metformin-strength therapy — for patients requiring full 1000mg Metformin dosing alongside Sitagliptin
- Prevention of long-term diabetes complications — reducing the risk of kidney damage, heart attack, and stroke with sustained glycaemic control
- Step-up combination therapy — for patients previously on Sitaglu Met 50/850mg requiring further intensification
How Does Sitaglu Met 50/1000mg Work?
Sitagliptin 50mg — DPP-4 Inhibitor: Blocks the DPP-4 enzyme that breaks down incretin hormones (GLP-1 and GIP), preserving their blood sugar lowering action. This stimulates glucose-dependent insulin secretion from the pancreas — meaning insulin is released only when blood sugar is actually elevated, keeping hypoglycaemia risk very low. Sitagliptin simultaneously suppresses glucagon, the hormone that raises blood sugar between meals and overnight.
Metformin Hydrochloride 1000mg — Biguanide: At the full 1000mg dose, Metformin provides maximum suppression of hepatic gluconeogenesis — the liver's production of excess glucose that drives elevated fasting blood sugar levels. It also delivers its strongest peripheral insulin-sensitising effect in muscle and fat cells, improving the body's ability to absorb and use glucose throughout the day. Metformin does not stimulate insulin production, maintaining low hypoglycaemia risk when used without insulin or sulphonylureas.
Combined Effect: Maximum-dose Metformin comprehensively controls fasting and between-meal glucose while Sitagliptin specifically manages post-meal blood sugar spikes — providing the most complete glycaemic coverage available from this combination.
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 (maximum combination therapy) | 1 tablet (50mg/1000mg) | Twice daily with meals |
- Always take with meals — the 1000mg Metformin dose requires food to minimise stomach side effects
- Swallow whole with a full glass of water
- Take at the same time each day for consistent blood sugar control
- Regular HbA1c, kidney function, and Vitamin B12 monitoring is essential during long-term treatment
Active Ingredients
| Ingredient | Strength per Tablet |
|---|---|
| Sitagliptin | 50mg |
| Metformin Hydrochloride | 1000mg |
Who Should NOT Take Sitaglu Met 50/1000mg?
- Type 1 diabetes or diabetic ketoacidosis
- Severe kidney disease (eGFR below 30) — Metformin is contraindicated
- Severe liver disease or personal history of lactic acidosis
- Known allergy to Sitagliptin, Metformin, or any component of the tablet
- History of pancreatitis — Sitagliptin component requires caution
- Pregnancy or breastfeeding — consult doctor immediately
Consult your doctor before use if you have: moderate kidney disease, liver disease, heart failure, history of pancreatitis, or are scheduled for surgery or any contrast imaging procedure.
Side Effects
Common:
- Nausea, stomach discomfort, or diarrhoea — most noticeable at 1000mg Metformin dose; always take with food without exception
- Metallic taste in the mouth — common Metformin effect, usually improves over time
- Mild headache or dizziness
- Nasopharyngitis (runny nose or mild sore throat) — common DPP-4 inhibitor class effect
Serious — seek medical attention immediately:
- Lactic acidosis — rare but life-threatening Metformin complication; muscle pain, weakness, difficulty breathing, stomach pain, feeling cold or dizzy (یہ طبی ہنگامی صورتحال ہے)
- Pancreatitis — severe persistent abdominal pain radiating to the back — Sitagliptin class risk
- Severe allergic reaction — facial swelling, difficulty breathing, widespread rash or blistering
- Hypoglycaemia — when combined with insulin or sulphonylureas — shakiness, sweating, confusion
- Vitamin B12 deficiency — with long-term use; fatigue, numbness or tingling in hands and feet
Drug Interactions
| Medicine | Interaction |
|---|---|
| Insulin / Sulphonylureas (e.g., Glibenclamide) | Increased hypoglycaemia risk — dose reduction may be needed when adding this combination |
| Iodinated contrast media (X-ray dye) | Metformin must be stopped before and 48 hours after contrast procedures — acute kidney failure risk |
| Alcohol (شراب) | Increases lactic acidosis risk from Metformin — avoid excessive alcohol completely |
| Digoxin | Sitagliptin may slightly increase Digoxin blood levels — monitoring advised |
| Corticosteroids | Raise blood sugar and reduce effectiveness of diabetes medicines |
| Diuretics (e.g., Furosemide) | May impair kidney function and increase Metformin accumulation and lactic acidosis risk |

Frequently Asked Questions (FAQs)
Q: What makes Sitaglu Met 50/1000mg different from the 50/500mg and 50/850mg strengths? The 1000mg version contains the full standard therapeutic Metformin dose — prescribed when lower strengths no longer provide adequate fasting blood sugar control and maximum Metformin effect is needed.
Q: Why is taking this tablet with food especially important at 1000mg Metformin? Higher Metformin doses cause significantly more nausea and stomach upset on an empty stomach — taking with food is not optional at this strength, it is essential for tolerability and adherence.
Q: Should I stop Sitaglu Met before surgery or a contrast scan? Yes — stop Metformin before any planned surgery and before procedures using contrast dye, and do not restart until 48 hours after and only once kidney function has been confirmed normal.
Q: How often should my kidneys be checked while taking this medicine? Kidney function should be checked at least once a year — more frequently if you are elderly or have any degree of existing kidney disease, as Metformin requires adequate kidney function to be safe.
