Metfonorm

Metformin Hydrochloride, the active ingredient in Metfonorm, is a biguanide presented as an oral tablet for oral use. It is used to improve glycemic control in adults with type 2 diabetes mellitus.

GNH USA supplies Metfonorm as a licensed, GDP‑compliant international pharmaceutical supplier serving hospitals, pharmacies and clinics worldwide.

Metfonorm, a biguanide antidiabetic, acts on glucose metabolism pathways to lower blood sugar levels. - Type 2 diabetes mellitus: improves glycemic control and reduces HbA1c. - Prediabetes (impaired glucose tolerance): helps delay progression to overt diabetes. - Metabolic syndrome: contributes to better insulin sensitivity and modest weight reduction.

Metfonorm may cause a range of adverse reactions, most of which are mild and transient.

Common Side Effects: - Nausea: mild to moderate stomach upset. - Diarrhea: loose stools, often early in therapy. - Abdominal discomfort: cramping or bloating. - Metallic taste: transient alteration in taste perception. - Weight loss: modest reduction in body weight. - Vitamin B12 deficiency: decreased absorption over long‑term use.

Serious or Rare Side Effects: - Lactic acidosis: rare but potentially fatal metabolic acidosis. - Severe skin reactions: such as Stevens‑Johnson syndrome or toxic epidermal necrolysis. - Hepatic dysfunction: elevated liver enzymes or hepatitis. - Hypoglycemia: usually when combined with other antidiabetics. - Anemia: due to B12 deficiency. - Pancreatitis: very uncommon inflammation of the pancreas.

When prescribing Metfonorm, clinicians should consider several safety aspects. - Renal function: assess eGFR before initiation and periodically thereafter. - Hepatic impairment: use with caution in patients with liver disease. - Lactic acidosis risk: avoid in patients with conditions predisposing to hypoxia. - Vitamin B12 monitoring: check levels during long‑term therapy. - Pregnancy and lactation: use only if potential benefit justifies potential risk. - Store below 25°C: keep in the original pack, protect from moisture.

Metfonorm can interact with several medicines, altering its efficacy or safety profile.

Major Interactions (Avoid): - Iodinated contrast agents: increase risk of lactic acidosis; discontinue metformin before and after imaging. - Cimetidine: may raise metformin plasma concentrations. - Alcohol excess: potentiates lactic acidosis.

Moderate Interactions (Monitor Closely): - Beta‑blockers: may mask hypoglycemia symptoms. - Diuretics: can affect renal clearance of metformin. - Warfarin: may require INR monitoring due to possible interaction.
