Qosmet 50/500mg Tablets – Sitagliptin & Metformin for Type 2 Diabetes
Qosmet 50/500mg Tablets are a fixed-dose combination of Sitagliptin 50mg (DPP-4 inhibitor) and Metformin 500mg (biguanide) for the management of Type 2 diabetes mellitus. Sitagliptin enhances glucose-dependent insulin secretion and suppresses glucagon, while Metformin reduces hepatic glucose production and improves insulin sensitivity, providing complementary and additive glycaemic control. A valid prescription is required — use only as directed by your healthcare provider.

Qosmet 50/500mg Tablets – Sitagliptin & Metformin for Type 2 Diabetes
Description
Qosmet 50/500mg Tablets are a fixed-dose combination containing Sitagliptin 50mg, a DPP-4 (dipeptidyl peptidase-4) inhibitor, and Metformin 500mg, a biguanide antidiabetic agent. This combination targets two complementary mechanisms in Type 2 diabetes management: Sitagliptin enhances incretin-mediated insulin secretion and suppresses glucagon in a glucose-dependent manner, while Metformin reduces hepatic glucose production and improves peripheral insulin sensitivity. Together they provide additive glycaemic control with a lower risk of hypoglycaemia compared to sulphonylurea-based regimens.
Qosmet 50/500mg is indicated for adults with Type 2 diabetes whose blood glucose is inadequately controlled on metformin alone, or as an initial combination therapy for patients requiring both DPP-4 inhibition and metformin. It should be taken with meals to reduce gastrointestinal side effects from metformin. Regular HbA1c monitoring is recommended to assess glycaemic response. Renal function should be checked before initiation and periodically thereafter, as dose adjustment is required for moderate-to-severe renal impairment.
Common side effects include nausea, diarrhoea, headache, and upper respiratory infections. Rare but serious adverse effects include pancreatitis and lactic acidosis (a rare complication of metformin) — seek immediate medical care for severe abdominal pain, persistent vomiting, or muscle weakness. A valid prescription is required for this medicine.

FAQs
What is Qosmet 50/500mg used for?
Qosmet 50/500mg combines Sitagliptin 50mg and Metformin 500mg to improve blood glucose control in adults with Type 2 diabetes whose glycaemia is not adequately controlled on metformin alone.
Is Qosmet 50/500mg different from Gvia 100mg?
Yes. Gvia 100mg contains Sitagliptin alone at 100mg. Qosmet 50/500mg is a combination product with a lower Sitagliptin dose (50mg) paired with Metformin 500mg, intended for patients requiring both agents. Your doctor prescribes based on your treatment needs.
What are the signs of lactic acidosis with Metformin?
Lactic acidosis is a rare but serious complication. Signs include unusual muscle pain, breathing difficulty, stomach discomfort, cold or blue skin, dizziness, or irregular heartbeat. Seek emergency care immediately if these occur.
