Metformin: Everything You Need to Know

When working with Metformin, a widely prescribed oral medication that lowers blood glucose by reducing liver production and improving insulin sensitivity. Also known as Glucophage, it belongs to the Biguanides, a class of drugs that share a common mechanism of inhibiting mitochondrial respiration and is a first‑line option for Diabetes, a chronic condition where the body cannot properly manage blood sugar levels. This combination of attributes makes Metformin a cornerstone in managing type 2 diabetes and keeping HbA1c, the average blood‑sugar level over the past two to three months within target ranges.

Why does Metformin work so well? Its primary effect is to decrease hepatic glucose output, which cuts the amount of sugar released into the bloodstream each morning. At the same time, it boosts how muscle cells respond to insulin, so glucose gets pulled from the blood more efficiently. This double action—cutting production and enhancing uptake—lowers fasting glucose and post‑meal spikes, directly translating into lower HbA1c numbers. Most patients see a 1‑2% drop in HbA1c after a few months, and that improvement can reduce the risk of long‑term complications like eye disease, kidney damage, and nerve pain.

Dosage matters. Doctors typically start with 500 mg once a day, then slowly increase to 1,000 mg or 2,000 mg split into two doses, depending on tolerance and kidney function. Taking the dose with dinner often minimizes gastrointestinal upset, the most common side‑effect (nausea, bloating, or mild diarrhea). A small subset of people experience vitamin B12 depletion after years of use, so periodic blood checks are wise. For patients with advanced kidney disease, Metformin may be contraindicated because of the rare risk of lactic acidosis—a buildup of lactic acid that can be serious if the kidneys can’t clear it.
