Glucophage

Glucophage is a prescription oral medication that contains metformin hydrochloride, a biguanide class antidiabetic agent. It is marketed in the European Union and is typically supplied as tablets of various strengths. Metformin works by decreasing hepatic glucose production and improving peripheral insulin sensitivity, helping to control blood sugar levels in patients with type 2 diabetes. The product is available only with a doctor's prescription in many EU countries.

Glucophage is indicated for several metabolic conditions where improving insulin sensitivity and lowering hepatic glucose output are therapeutic goals.

- Management of type 2 diabetes mellitus as an adjunct to diet and exercise. - Off‑label treatment of polycystic ovary syndrome to improve ovulatory function. - Adjunctive therapy for pre‑diabetes to delay progression to diabetes. - Off‑label use in gestational diabetes when other options are unsuitable. - May be used in combination with other antidiabetic agents to achieve glycemic targets.

Side effects of Glucophage vary in frequency; some are mild and occur in many patients, while others are rare but may require medical attention.

Common: - Nausea or upset stomach. - Diarrhea or loose stools. - Metallic taste in the mouth. - Decreased appetite. - Unintended weight loss. - Abdominal discomfort or cramping.

Serious: - Lactic acidosis, a rare but life‑threatening condition. - Severe hypoglycemia when combined with insulin or sulfonylureas. - Vitamin B12 deficiency with long‑term use. - Skin rash or hypersensitivity reactions. - Hepatotoxicity or elevated liver enzymes.

Before starting Glucophage, certain health factors should be evaluated to minimize risks.

- Assess renal function; avoid use in severe renal impairment. - Evaluate liver disease status, as hepatic dysfunction can increase lactic acidosis risk. - Use cautiously in patients with congestive heart failure. - Limit alcohol consumption, which may potentiate lactic acidosis. - Monitor for vitamin B12 levels during prolonged therapy. - Consider dose adjustments in elderly patients. - Discuss pregnancy and breastfeeding status with a healthcare provider.

Glucophage can interact with several medicines, affecting its safety and effectiveness.

Avoid: - Iodinated contrast agents used for imaging studies. - Cimetidine, which can increase metformin plasma concentrations. - Certain antivirals such as didanosine that may raise the risk of lactic acidosis. - High‑dose diuretics that may impair renal clearance.

Use with caution: - Other antidiabetic drugs (insulin, sulfonylureas) due to hypoglycemia risk. - Corticosteroids, which can raise blood glucose levels. - Beta‑blockers that may mask hypoglycemia symptoms. - ACE inhibitors or ARBs that affect renal function. - Non‑steroidal anti‑inflammatory drugs (NSAIDs) that may reduce kidney perfusion.
