Metformin Zentiva belongs to the biguanide class and is used to improve glycaemic control in patients with type 2 diabetes mellitus.

- Type 2 diabetes mellitus: lowers fasting and post‑prandial blood glucose levels, helping achieve target HbA1c values.

Metformin may cause a range of adverse reactions, most of which are related to the gastrointestinal tract, while rare events can be serious.

Common Side Effects: - Nausea: mild to moderate upset stomach. - Diarrhea: loose stools, often transient. - Abdominal discomfort: cramping or bloating. - Metallic taste: transient alteration of taste perception. - Loss of appetite: reduced desire to eat. - Flatulence: increased intestinal gas.

Serious or Rare Side Effects: - Lactic acidosis: a rare but life‑threatening metabolic disturbance. - Severe skin reactions: such as Stevens‑Johnson syndrome. - Hepatotoxicity: abnormal liver function tests. - Hypoglycaemia: when combined with other glucose‑lowering agents. - Vitamin B12 deficiency: may develop with long‑term use. - Pancreatitis: inflammation of the pancreas.

Metformin should be used with careful clinical monitoring to minimise risks.

- Renal function monitoring: assess creatinine clearance before initiation and periodically thereafter. - Hepatic assessment: evaluate liver enzymes in patients with known liver disease. - Lactic acidosis risk: avoid in patients with conditions predisposing to hypoxia or severe infection. - Concomitant medication review: consider interactions that may increase metformin exposure. - Dose adjustment in elderly: start at lower dose and titrate cautiously. - Store at room temperature: keep in the original container, protect from moisture and heat.

Metformin may interact with several medicines, requiring attention to avoid reduced efficacy or increased toxicity.

Major Interactions (Avoid): - Iodinated contrast agents: can precipitate acute renal failure and lactic acidosis. - Cimetidine: may increase metformin plasma concentrations. - Alcohol: potentiates risk of lactic acidosis.

Moderate Interactions (Monitor Closely): - Beta‑blockers: may mask hypoglycaemia symptoms. - Diuretics: can affect renal clearance of metformin.
