SITA-M 500MG

# METFORMIN 1000 MG + SITAGLIPTIN PHOSPHATE 50 MG ## SHORT DESCRIPTION **Metformin 1000 mg + Sitagliptin Phosphate 50 mg** is an oral combination medicine used to help control **blood glucose levels in adults with type 2 diabetes mellitus**. It combines metformin, a biguanide, with sitagliptin, a DPP-4 inhibitor. Metformin primarily reduces glucose production by the liver and improves insulin sensitivity, while sitagliptin increases glucose-dependent insulin release and reduces glucagon secretion. Together, they help improve blood glucose control without directly replacing insulin. > **Important:** Sitagliptin 50 mg is commonly used when a lower sitagliptin dose is appropriate, including in certain patients with reduced kidney function. The exact dose should be determined by a healthcare professional. --- ## KEY BENEFITS * Helps improve **blood glucose control** in type 2 diabetes. * Combines two complementary diabetes medicines. * Metformin helps reduce excessive glucose production by the liver. * Sitagliptin enhances the body's natural **incretin response**. * Generally has a low risk of hypoglycemia when used alone or with metformin. * May help reduce HbA1c when diet and exercise alone are insufficient. * Can be used as part of an individualized diabetes-management plan. --- ## USES / INDICATIONS Metformin 1000 mg + Sitagliptin 50 mg may be prescribed for: 1. **Type 2 diabetes mellitus** 2. Improving blood glucose control when metformin alone is insufficient 3. Patients who require combination therapy with metformin and sitagliptin 4. Maintaining glycemic control alongside appropriate **diet and exercise** ### Not Intended for Type 1 Diabetes This combination is generally **not used to treat type 1 diabetes mellitus** or diabetic ketoacidosis. --- ## HOW IT WORKS ### Metformin Metformin lowers blood glucose primarily by: * Reducing **glucose production by the liver** * Improving insulin sensitivity * Increasing peripheral glucose uptake * Reducing intestinal glucose absorption to a smaller extent It does not normally stimulate the pancreas to release insulin, so metformin alone has a relatively low risk of hypoglycemia. ### Sitagliptin Sitagliptin is a **DPP-4 inhibitor**. It prevents the breakdown of incretin hormones such as GLP-1 and GIP. This helps: * Increase insulin release when blood glucose is elevated * Reduce glucagon secretion when glucose is elevated * Decrease hepatic glucose production ### Combined Action **Metformin → reduces hepatic glucose production + improves insulin sensitivity** **Sitagliptin → enhances glucose-dependent insulin response + reduces glucagon** Together, these mechanisms help improve blood glucose control. --- ## DOSAGE & ADMINISTRATION ### Usual Administration The appropriate dose depends on: * Current diabetes control * Kidney function * Previous diabetes medicines * Tolerability * Other medicines being taken * The exact formulation of the product A product containing **metformin 1000 mg + sitagliptin 50 mg** should be taken exactly as prescribed. ### Important Kidney Consideration Sitagliptin dosing is adjusted according to kidney function. A **50 mg sitagliptin dose is commonly used in moderate renal impairment**, while more severe impairment may require a lower dose. Metformin may also need dose adjustment or discontinuation depending on kidney function. ### How to Take * Take with food if instructed; metformin is generally better tolerated when taken with meals. * Swallow the tablet whole if it is an extended-release formulation. * Do not crush or chew extended-release tablets unless the product specifically permits it. * Continue the recommended diabetes diet and exercise plan. * Monitor blood glucose as recommended. ### Missed Dose Take the missed dose when remembered unless it is almost time for the next dose. **Do not take two doses together.** --- ## SIDE EFFECTS ### Common Side Effects Possible side effects include: * Nausea * Diarrhea * Abdominal discomfort * Bloating * Gas * Indigestion * Headache * Upper respiratory symptoms Gastrointestinal effects are particularly common when starting metformin and may improve with continued treatment. ### Vitamin B12 Long-term metformin treatment can reduce **vitamin B12 levels** in some people. Periodic monitoring may be appropriate, particularly in patients with anemia, neuropathy, or other risk factors for B12 deficiency. ### Low Blood Sugar Hypoglycemia is generally uncommon when metformin and sitagliptin are used without insulin or insulin-releasing medicines. The risk increases when combined with: * Insulin * Sulfonylureas * Other glucose-lowering medicines ### Serious Side Effects Seek medical attention for: * Severe or persistent abdominal pain * Persistent vomiting * Severe weakness * Difficulty breathing * Signs of dehydration * Severe allergic reaction * Symptoms suggestive of pancreatitis --- ## PRECAUTIONS & WARNINGS ### Lactic Acidosis Metformin carries a rare but serious risk of **lactic acidosis**. The risk increases with significant kidney impairment, severe dehydration, certain acute illnesses, excessive alcohol intake, and conditions associated with tissue hypoxia. Seek urgent medical attention for unusual: * Weakness * Extreme tiredness * Trouble breathing * Persistent vomiting * Abdominal discomfort * Feeling unusually cold * Slow or irregular heartbeat ### Kidney Function Kidney function should be assessed before and during metformin treatment. Metformin is generally contraindicated in **severe renal impairment**, and sitagliptin also requires dose adjustment according to renal function. ### Contrast Imaging Metformin may need to be temporarily withheld around certain **iodinated contrast imaging procedures**, depending on kidney function and the type of procedure. Follow the instructions provided by the healthcare professional performing the examination. ### Pancreatitis Sitagliptin has been associated with reports of **acute pancreatitis**. Contact a healthcare professional promptly if persistent severe abdominal pain occurs, especially if it radiates to the back and is accompanied by vomiting. ### Heart Failure Tell your healthcare professional if you have heart failure or other significant heart disease. ### Liver Disease Inform your healthcare professional about liver disease before taking this combination. ### Alcohol Excessive alcohol intake can increase the risk of metformin-associated lactic acidosis and may also affect blood glucose. ### Pregnancy If you are pregnant, planning pregnancy, or become pregnant while taking this medicine, discuss treatment with your healthcare professional. ### Breastfeeding Discuss the use of metformin/sitagliptin with your healthcare professional if breastfeeding. --- ## DRUG INTERACTIONS ### Insulin and Sulfonylureas Combining sitagliptin with insulin or sulfonylureas may increase the risk of **hypoglycemia**. Dosage adjustments may be required. ### Iodinated Contrast Agents Some contrast procedures can increase the risk of kidney injury, which can subsequently increase the risk associated with metformin. Follow medical instructions regarding temporary interruption. ### Cimetidine Cimetidine may increase metformin exposure and may require additional clinical consideration. ### Alcohol Excessive alcohol consumption can increase the risk of **metformin-associated lactic acidosis**. ### Other Diabetes Medicines Tell your healthcare professional if you use: * Insulin * Sulfonylureas * SGLT2 inhibitors * GLP-1 receptor agonists * Thiazolidinediones * Other glucose-lowering medicines ### Other Medicines Affecting Kidney Function Certain medicines can affect kidney function and may require additional monitoring when used with metformin.
