Metformin Hydrochloride Accord Healthcare (Metformin Hydrochloride)

Metformin Hydrochloride is used in the management of type 2 diabetes mellitus, a disorder of glucose metabolism.

• Type 2 diabetes mellitus: improves glycemic control by lowering fasting and post‑prandial blood glucose levels.
• Prediabetes: reduces the risk of progression to overt diabetes through improved insulin sensitivity.
• Polycystic ovary syndrome: helps ameliorate insulin resistance and may improve menstrual regularity.

• Metformin Hydrochloride acts primarily by inhibiting hepatic gluconeogenesis, thereby decreasing endogenous glucose production. It also enhances peripheral glucose uptake in muscle and adipose tissue by increasing insulin‑mediated signaling and improves insulin sensitivity. Additional actions include modest reduction of intestinal glucose absorption and favorable effects on lipid metabolism, contributing to its overall antidiabetic profile.

Metformin Hydrochloride may cause a range of adverse reactions, varying from mild to serious.

Common Side Effects

• Nausea: transient stomach upset, often mild.
• Diarrhea: loose stools, usually early in therapy.
• Abdominal discomfort: cramping or pain in the abdomen.
• Metallic taste: temporary alteration of taste perception.
• Weight loss: modest reduction in body weight.
• Vitamin B12 deficiency: decreased absorption with long‑term use.

Serious or Rare Side Effects

• Lactic acidosis: rare but life‑threatening accumulation of lactate.
• Severe skin reactions: such as Stevens‑Johnson syndrome or toxic epidermal necrolysis.
• Hepatic dysfunction: signs of liver injury including jaundice.
• Hypoglycemia: when combined with other glucose‑lowering agents.
• Pancreatitis: inflammation of the pancreas.
• Anemia: due to reduced red blood cell production.

Before initiating Metformin Hydrochloride, several precautionary measures should be considered to ensure safe use.

• Renal function: assess creatinine clearance and avoid use in severe renal impairment.
• Liver disease: use with caution and monitor hepatic enzymes.
• Alcohol consumption: limit intake to reduce risk of lactic acidosis.
• Concomitant medications: review for drugs that may affect renal function or increase metformin levels.
• Pregnancy and lactation: discuss potential risks with the prescriber.
• Store at ambient temperature: keep below 25 °C in the original packaging, protected from moisture and light.

Metformin Hydrochloride can interact with other medicines, influencing its efficacy or safety.

Major Interactions (Avoid)

• Iodinated contrast agents: may precipitate acute renal failure and increase lactic acidosis risk.
• Cimetidine: can raise metformin plasma concentrations.
• Alcohol: excessive intake heightens lactic acidosis potential.

Moderate Interactions (Monitor Closely)

• Beta‑blockers: may mask symptoms of hypoglycemia.
• Diuretics: can affect renal clearance of metformin.
• ACE inhibitors or ARBs: require monitoring of renal function and electrolytes.
