Metformin Sandoz

Metformin, the active ingredient in Metformin Sandoz, is a Biguanide presented as a unknown/unknown for oral use. It treats type 2 diabetes mellitus in adults by improving blood glucose control. GNH USA supplies Metformin Sandoz as a licensed, GDP‑compliant international pharmaceutical supplier serving hospitals, pharmacies and clinics worldwide.

Metformin is indicated for conditions involving impaired glucose metabolism and insulin resistance. - Type 2 diabetes mellitus: improves glycemic control and reduces HbA1c levels. - Prediabetes (impaired glucose tolerance): helps delay progression to overt diabetes. - Polycystic ovary syndrome: may improve insulin sensitivity and restore ovulatory function.

Metformin is generally well tolerated, but several adverse reactions have been reported.

Common Side Effects: - Nausea: mild to moderate stomach upset. - Diarrhea: frequent loose stools, especially during dose titration. - Abdominal discomfort: cramping or bloating. - Metallic taste: transient alteration of taste perception. - Loss of appetite: reduced desire to eat. - Vitamin B12 deficiency: decreased absorption with long‑term use.

Serious or Rare Side Effects: - Lactic acidosis: rare but life‑threatening metabolic acidosis. - Severe skin reactions: such as Stevens‑Johnson syndrome or toxic epidermal necrolysis. - Hepatic dysfunction: marked elevation of liver enzymes. - Pancreatitis: inflammation of the pancreas. - Hypoglycemia: when combined with other glucose‑lowering agents. - Anemia: due to reduced red blood cell production.

Metformin should be used with careful clinical monitoring and patient education. - Renal function: assess eGFR before initiating and periodically thereafter. - Hepatic disease: avoid in patients with severe liver impairment. - Alcohol consumption: limit intake to reduce risk of lactic acidosis. - Pregnancy: discuss risks and benefits with the prescriber; use only if clearly needed. - Elderly patients: monitor renal function closely due to age‑related decline. - Store at ambient temperature: keep in the original container, protect from moisture and heat.

Metformin may interact with several medicines, requiring dose adjustment or monitoring.

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

Moderate Interactions (Monitor Closely): - Beta‑blockers: may mask symptoms of hypoglycemia. - Diuretics (especially thiazides): affect renal clearance of metformin. - ACE inhibitors or ARBs: require monitoring of renal function and electrolytes.
