Bigmet 850 mg Tablet

Bigmet 850 mg Tablet — Metformin Hydrochloride

Overview

Bigmet 850 is a higher-strength metformin tablet from Renata Limited, intended for type 2 diabetes patients who need a stronger per-tablet dose than 500 mg to achieve adequate glycemic control.

Mechanism of Action

Metformin reduces hepatic glucose production, decreases intestinal glucose absorption, and improves peripheral insulin sensitivity in muscle and adipose tissue, without directly stimulating pancreatic insulin secretion.

Indications

Bigmet 850 is indicated for type 2 diabetes mellitus in patients requiring a higher metformin dose, often introduced after the 500 mg strength has been well tolerated.

Dosage and Administration

A typical regimen starts at 850 mg once daily with a meal, increasing to twice daily after 1–2 weeks if tolerated, up to a maximum total daily dose of approximately 2550 mg.

Contraindications

Contraindicated in severe renal impairment (eGFR <30 mL/min/1.73m²), metabolic acidosis including diabetic ketoacidosis, and known hypersensitivity to metformin.

Side Effects

Gastrointestinal effects such as nausea, diarrhea, and abdominal discomfort are most common during initial dose step-up. Long-term use may reduce vitamin B12 absorption.

Drug Interactions

Iodinated contrast media require temporary discontinuation of metformin. Alcohol intake should be limited. Disclose all current medications and supplements to your physician or pharmacist.

Special Precautions

Renal function should be reassessed before stepping up to this higher strength and monitored periodically thereafter.

Storage

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