Insimet 500 mg Tablet

Insimet 500 mg Tablet — Metformin Hydrochloride

Overview

Insimet 500 mg in the standard 100-tablet strip pack is a convenient, everyday retail option for patients newly starting metformin therapy or refilling an ongoing prescription. Manufactured by The Ibn Sina Pharmaceutical Ind. Ltd., this pack size is sized for typical individual patient use, making it easy to purchase the right quantity for a one- to two-month supply depending on dosing.

Mechanism of Action

Metformin reduces blood glucose by decreasing hepatic glucose production, lowering intestinal glucose absorption, and improving insulin sensitivity in peripheral tissues. It does not increase insulin secretion from the pancreas, so the risk of hypoglycemia is minimal when used alone, distinguishing it from sulfonylureas and similar insulin secretagogues.

Indications

Insimet 500 mg is indicated as first-line oral therapy for type 2 diabetes mellitus, used alongside diet and exercise. It may be combined with other oral antidiabetics, GLP-1 agonists, or insulin when monotherapy does not achieve target glycemic control, and is occasionally used off-label for insulin resistance in PCOS under medical supervision.

Dosage and Administration

A typical starting dose is 500 mg once or twice daily with meals, titrated upward gradually over 1–2 weeks based on response and tolerance, with maintenance doses commonly between 1500–2000 mg/day. Taking the tablet with food reduces gastrointestinal discomfort. Always follow your physician's personalized dosing schedule.

Contraindications

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

Side Effects

The most frequent side effects are gastrointestinal — nausea, diarrhea, abdominal discomfort, and a metallic taste — typically mild and improving with gradual titration and food intake. Long-term therapy may lower vitamin B12 absorption, so periodic monitoring is advisable. Lactic acidosis is a rare but serious risk in patients with predisposing renal or hepatic conditions.

Drug Interactions

Iodinated contrast media for imaging procedures require temporary discontinuation of metformin due to the risk of acute kidney injury and lactic acidosis. Excessive alcohol intake should be avoided. Always inform your physician or pharmacist about all medications and supplements you currently take.

Special Precautions

Renal function should be checked at baseline and periodically monitored thereafter, especially in elderly patients. Metformin should be temporarily withheld during acute illness involving dehydration, vomiting, or significant hypoxia. Use during pregnancy and breastfeeding should be individualized by your physician.

Storage

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