Insimet 850 mg Tablet

Insimet 850 mg Tablet — Metformin Hydrochloride

Overview

Insimet 850 mg in the standard 100-tablet retail pack offers a higher per-tablet metformin dose for patients who have progressed beyond the 500 mg starting strength. This pack size is suited for individual patient prescriptions, allowing convenient pharmacy purchase for ongoing maintenance therapy in type 2 diabetes.

Mechanism of Action

Metformin lowers blood glucose by reducing hepatic glucose output, decreasing intestinal glucose absorption, and improving insulin sensitivity in peripheral tissues such as skeletal muscle. It works independently of insulin secretion, keeping hypoglycemia risk low when used as monotherapy.

Indications

Insimet 850 mg is indicated for type 2 diabetes mellitus in patients requiring a higher metformin dose per tablet, generally as a step up once tolerance to lower doses is established. It may be used alone or combined with other oral antidiabetics or insulin under physician supervision.

Dosage and Administration

A typical regimen begins with 850 mg once daily with a meal, increasing to twice daily after 1–2 weeks if clinically indicated and tolerated, up to a generally accepted maximum of approximately 2550 mg/day combined across metformin products. Taking the tablet with food reduces the likelihood of gastrointestinal upset.

Contraindications

Contraindicated in severe renal impairment (eGFR <30 mL/min/1.73m²), metabolic acidosis including diabetic ketoacidosis, and known hypersensitivity to metformin. Use cautiously in hepatic impairment or in conditions predisposing to tissue hypoxia or volume depletion.

Side Effects

Gastrointestinal symptoms such as nausea, diarrhea, and abdominal discomfort are the most common, particularly during the initial step-up period; gradual titration and taking the tablet with food help reduce these effects. Vitamin B12 levels may decline with long-term use. Lactic acidosis is rare and primarily affects patients with underlying renal or hepatic disease.

Drug Interactions

Use of iodinated contrast media requires temporary discontinuation of metformin due to acute kidney injury and lactic acidosis risk. Alcohol intake should be minimized. Disclose all current medications and supplements to your physician or pharmacist before starting therapy.

Special Precautions

Renal function should be assessed before initiation and monitored periodically, particularly in older adults. Temporary discontinuation is recommended during acute illness involving dehydration, vomiting, or reduced tissue oxygenation.

Storage

Store below 30°C in a dry place, protected from light and moisture. Keep out of reach of children.
