Meguan

Metformin Hydrochloride, the active ingredient in Meguan, is a biguanide presented as an oral tablet for oral use. It lowers blood glucose levels and is used to manage type 2 diabetes mellitus in adults. GNH USA supplies Meguan as a licensed, GDP‑compliant international pharmaceutical supplier serving hospitals, pharmacies and clinics worldwide.

Meguan (metformin) is employed in the management of disorders related to glucose metabolism. - Type 2 diabetes mellitus: improves glycaemic control by reducing hepatic glucose output and enhancing insulin sensitivity. - Prediabetes (impaired glucose tolerance): helps delay progression to overt diabetes by lowering fasting glucose levels. - Polycystic ovary syndrome (off‑label): may improve insulin resistance and restore ovulatory cycles.

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

Common Side Effects: - Gastrointestinal upset: nausea, abdominal discomfort, and diarrhoea are frequent during treatment initiation. - Metallic taste: a transient metallic sensation in the mouth may occur. - Vitamin B12 deficiency: long‑term therapy can reduce absorption of vitamin B12.

Serious or Rare Side Effects: - Lactic acidosis: a rare but life‑threatening accumulation of lactate, especially in patients with renal impairment. - Severe skin reactions: such as Stevens‑Johnson syndrome or toxic epidermal necrolysis. - Hepatic dysfunction: rare cases of liver enzyme elevation have been observed.

Meguan should be used with careful clinical monitoring. - Renal function: assess creatinine clearance before initiation and periodically thereafter. - Hepatic disease: avoid in patients with significant liver impairment. - Alcohol consumption: limit intake as it may increase the risk of lactic acidosis. - Pregnancy and lactation: use only if the potential benefit outweighs the risk; consult a healthcare professional. - Drug interactions: review concomitant medications for potential interactions that may affect metformin levels. Store at ambient temperature: keep in the original container, protect from moisture and direct sunlight.

Metformin may interact with several medicines, altering its efficacy or safety profile.

Major Interactions (Avoid): - Iodinated contrast agents: can precipitate acute renal failure, increasing lactic acidosis risk. - Cimetidine: may raise metformin plasma concentrations, heightening toxicity.

Moderate Interactions (Monitor Closely): - Diuretics (thiazides, loop): can affect renal function and electrolyte balance. - ACE inhibitors or ARBs: may enhance renal protective effects but require monitoring of kidney function. - Beta‑blockers: may mask hypoglycaemia symptoms; monitor blood glucose closely.
