ST-GLIPTIN M50/1000

Sitagliptin/metformin 50/1000 is a prescription combination medicine used with diet and exercise to help improve blood glucose control in adults with type 2 diabetes mellitus. It combines sitagliptin 50 mg, a DPP-4 inhibitor, with metformin hydrochloride 1000 mg, a biguanide medicine. The two ingredients work through different mechanisms to help lower elevated blood sugar.

For people searching for sitagliptin/metformin 50/1000 uses, benefits, side effects, dosage, price, or online availability, it is important to understand that this medicine is not suitable for everyone. Kidney function, other diabetes medicines, medical history, formulation, and individual blood glucose targets all influence whether this strength is appropriate.

What Is Sitagliptin-Metformin 50/1000?

Sitagliptin/metformin 50/1000 contains two active ingredients:

• Sitagliptin 50 mg – a DPP-4 inhibitor that helps increase the body's glucose-dependent insulin response and reduce glucagon secretion.

• Metformin 1000 mg – a biguanide that primarily reduces glucose production by the liver and improves insulin sensitivity.

Combining these medicines can provide complementary blood-glucose-lowering effects. The combination is intended for adults with type 2 diabetes when diet and exercise alone, or an existing treatment regimen, do not provide adequate glycemic control.

The exact formulation matters. Some sitagliptin/metformin products are immediate-release, and others are extended-release or sustained-release formulations. Do not assume that every 50/1000 product is taken in exactly the same way. Always follow the product label and your prescription.

Sitagliptin/Metformin 50/1000 Uses

The primary use of sitagliptin/metformin 50/1000 is to improve blood glucose control in adults with type 2 diabetes mellitus, alongside appropriate diet and exercise.

It may be prescribed in situations where:

• Metformin alone does not adequately control blood sugar.

• A patient is already taking sitagliptin and metformin separately and needs a combination formulation.

• Additional therapy is required alongside other diabetes medicines in selected patients.

The combination is not intended for treating type 1 diabetes.

Why are two medicines combined?

Type 2 diabetes involves several abnormalities in glucose regulation. Using medicines with complementary mechanisms can provide better glycemic control than relying on a single mechanism for some patients.

However, combination therapy should be individualized. A stronger dose is not automatically better, and the correct treatment depends on blood glucose levels, kidney function, other medications and treatment goals.

How Does Sitagliptin Metformin 50/1000 Work?

Sitagliptin 50 mg

Sitagliptin belongs to the DPP-4 inhibitor class. It helps enhance incretin activity, which contributes to increased insulin release when blood glucose is elevated and reduced glucagon secretion.

Because its glucose-lowering effect is glucose-dependent, sitagliptin generally has a lower risk of hypoglycemia when used alone or with metformin than medicines that directly stimulate insulin secretion. However, the risk can increase when it is combined with insulin or a sulfonylurea.

Metformin 1000 mg

Metformin primarily decreases glucose production by the liver and improves the body's response to insulin. It is one of the foundational medicines used in type 2 diabetes management.

Together, sitagliptin and metformin address blood glucose through complementary pathways.

Key Benefits of Sitagliptin/Metformin 50/1000

1. Helps control high blood sugar

The main therapeutic benefit is improved glycemic control in adults with type 2 diabetes when used as prescribed alongside diet and exercise.

2. Combines two glucose-lowering mechanisms

Sitagliptin and metformin work differently, allowing a single combination product to provide two complementary pharmacological approaches.

3. Can be useful when metformin alone is insufficient

For some adults whose blood glucose remains above target despite tolerated metformin therapy, adding sitagliptin can improve glycemic control.

4. May simplify a treatment regimen

For patients who have been prescribed both active ingredients, a fixed-dose combination can reduce the number of separate tablets required.

5. Generally has a relatively low hypoglycemia risk with metformin alone

Sitagliptin and metformin do not typically cause hypoglycemia as frequently as insulin or sulfonylureas when used without other glucose-lowering agents that increase this risk. However, hypoglycemia can occur, particularly when the combination is used with insulin or a sulfonylurea.

Sitagliptin-Metformin 50/1000 Dosage

The correct dose depends on the specific formulation and the patient's existing diabetes regimen.

This is particularly important because 50 mg sitagliptin + 1000 mg metformin may be supplied in different formulations. For example, current prescribing information for immediate-release sitagliptin/metformin describes dosing twice daily with meals and a maximum total daily dose of 100 mg sitagliptin and 2000 mg metformin.

Therefore, do not interpret “50/1000” as meaning that every product should automatically be taken once daily or twice daily.

Kidney function is important

Before starting sitagliptin/metformin, renal function should be assessed. Current U.S. prescribing information states that the combination should not be used when eGFR is below 30 mL/min/1.73 m² and is not recommended when eGFR is 30 to less than 45 mL/min/1.73 m² for the referenced immediate-release product.

Your doctor may select a different treatment or adjust therapy according to kidney function.

Take it exactly as prescribed

Do not:

• Double a dose after missing one unless specifically instructed.

• Crush or split a tablet when the product instructions prohibit it.

• Substitute an extended-release product for an immediate-release product without professional advice.

• Change the strength based solely on online availability.

Sitagliptin-Metformin 50/1000 Side Effects

Like all medicines, sitagliptin and metformin can cause adverse effects.

Commonly reported gastrointestinal effects include:

• Nausea

• Vomiting

• Diarrhea

• Flatulence

• Abdominal discomfort

• Metallic taste

Headache and other adverse effects may also occur. Current product information identifies nausea, flatulence, and vomiting as common adverse reactions, while diarrhea, constipation, and upper abdominal pain are listed as less common.

Vitamin B12 deficiency

Long-term metformin therapy can be associated with decreased vitamin B12 levels or deficiency. Patients receiving prolonged treatment may need assessment when clinically appropriate, particularly if symptoms or risk factors suggest deficiency.

Hypoglycemia

Hypoglycemia is generally less likely with sitagliptin/metformin alone than with insulin or some insulin-secretagogue medicines. However, the risk can increase when the combination is taken with insulin or a sulfonylurea.

Symptoms may include sweating, shakiness, hunger, confusion, weakness, or dizziness.

Serious Side Effects and Warnings

Although uncommon, serious reactions can occur.

Lactic acidosis

Metformin carries a rare but serious risk of metformin-associated lactic acidosis. Risk is increased by factors such as significant renal impairment, certain drug interactions, excessive alcohol use, hepatic impairment, surgery, and some conditions involving reduced oxygen supply.

Symptoms requiring urgent medical assessment can include unusual weakness, severe tiredness, breathing difficulties, abdominal discomfort, dizziness, or feeling unusually cold.

Pancreatitis

Sitagliptin has been associated with reports of acute pancreatitis. Severe persistent abdominal pain, particularly if it radiates to the back and is accompanied by vomiting, requires prompt medical evaluation.

Allergic reactions

Serious hypersensitivity reactions can occur. Seek urgent medical help for facial, lip, or throat swelling, difficulty breathing, widespread rash, or other signs of a severe allergic reaction.

Who Should Be Careful With Sitagliptin/Metformin 50/1000?

Before taking this medicine, tell your healthcare professional if you have:

• Kidney disease

• Liver disease

• A history of pancreatitis

• Heart failure or significant cardiovascular disease

• Excessive alcohol consumption

• A planned surgery

• A planned imaging procedure involving iodinated contrast

• A history of allergic reactions to sitagliptin or metformin

• Other diabetes medicines

Renal function is particularly important because metformin accumulation in significant renal impairment increases the risk of lactic acidosis.

Sitagliptin-Metformin 50/1000 and Drug Interactions

Always provide your doctor or pharmacist with a complete list of your medicines.

Potentially relevant treatments include the following:

• Insulin

• Sulfonylureas

• Other diabetes medicines

• Certain medicines affecting kidney function

• Medicines that can alter blood glucose

• Contrast agents used in some imaging procedures

When sitagliptin/metformin is combined with insulin or a sulfonylurea, healthcare professionals may need to adjust the other medicine because of increased hypoglycemia risk.

For certain contrast-imaging procedures, metformin may need to be temporarily discontinued depending on kidney function and the clinical circumstances.

Can You Buy Sitagliptin/Metformin 50/1000 Online?

Yes. Current Indian online pharmacy listings show multiple sitagliptin 50 mg + metformin 1000 mg products, and these listings generally identify them as prescription medicines.

For example, as of August 2026, one online listing showed Sitamet 50/1000 Tablet SR at ₹99.20 for a strip of 10, while a separate listing showed Janumet 50/1000 at ₹307 for 15 tablets after a discount. Another pharmacy listing showed Sitaglyn M 50/1000 at ₹108.90 for 10 tablets. Prices, pack sizes, availability, and discounts can change.

These examples demonstrate why shoppers should compare price per tablet, formulation, pack size, and exact composition, rather than comparing the headline pack price alone.

The Indian government has also previously reported availability of generic sitagliptin + metformin 50/1000 mg through Jan Aushadhi channels at substantially lower prices than some branded alternatives. Because that published price information dates from 2022, it should not be treated as the current retail price.

What to check before buying

If you are searching for “buy sitagliptin metformin 50/1000” or “sitagliptin metformin 50/1000 price,” check:

1. Exact composition: Sitagliptin 50 mg + metformin 1000 mg.

2. Formulation: Immediate-release, extended-release, or sustained-release.

3. Prescription requirement: Follow the pharmacy's prescription-verification process.

4. Manufacturer: Verify the manufacturer and marketer.

5. Pack size: Compare cost per tablet.
