Glucophage (Metformin Hydrochloride)

Glucophage is indicated primarily for the management of type 2 diabetes mellitus in adults.

• Improves glycemic control as part of a comprehensive diabetes management plan that includes diet and exercise.
• Can be used as monotherapy when metformin alone is sufficient to achieve target blood glucose levels.
• May be combined with other oral antidiabetic agents or insulin when additional glucose lowering is needed.
• Helps reduce the risk of diabetes‑related complications by maintaining more stable blood glucose concentrations.
• Often prescribed for patients with overweight or obesity, as metformin may modestly aid weight management.

Side effects of Glucophage vary in frequency and severity; most are mild and transient, while rare reactions may require medical attention.

Common

• Gastrointestinal upset such as nausea, abdominal discomfort, or diarrhea.
• Metallic taste in the mouth.
• Decreased appetite.
• Mild headache.

Serious

• Lactic acidosis, a rare but potentially life‑threatening condition characterized by rapid breathing, muscle pain, or unusual fatigue.
• Severe skin reactions, including Stevens‑Johnson syndrome or toxic epidermal necrolysis.
• Significant vitamin B12 deficiency with prolonged use.

Before starting Glucophage, certain health considerations and monitoring requirements should be reviewed with a healthcare professional.

• Assess renal function; metformin is contraindicated in severe renal impairment.
• Evaluate liver function, as hepatic disease can increase the risk of lactic acidosis.
• Use caution in patients with heart failure or a history of hypoxia.
• Monitor blood glucose regularly to avoid hypoglycemia, especially when combined with other glucose‑lowering drugs.
• Periodic assessment of vitamin B12 levels is recommended for long‑term therapy.
• Discontinue before any radiographic studies that involve iodinated contrast agents.

Glucophage may interact with other medicines, affecting its efficacy or safety profile.

Avoid

• Iodinated contrast agents used in imaging studies; they can precipitate acute kidney injury and increase lactic acidosis risk.
• Certain cationic drugs (e.g., trimethoprim, pyrimethamine) that may reduce metformin clearance.
• Alcohol excess, which can potentiate lactic acidosis.

Use with caution

• Other antidiabetic agents, especially sulfonylureas or insulin, due to increased hypoglycemia risk.
• Diuretics that may affect renal function and metformin elimination.
• Corticosteroids, which can raise blood glucose and alter metformin dosing needs.
