Metformin Milpharm (Metformin Hydrochloride)

Metformin Milpharm is used in the management of disorders related to impaired glucose metabolism, primarily type 2 diabetes mellitus.

• Type 2 diabetes mellitus: lowers fasting plasma glucose and HbA1c, helping achieve glycemic targets.
• Prediabetes: reduces progression to type 2 diabetes by improving insulin sensitivity.
• Polycystic ovary syndrome: improves insulin resistance and may help regulate menstrual cycles.

• Metformin acts primarily by inhibiting hepatic gluconeogenesis, thereby decreasing glucose production in the liver. It also reduces intestinal glucose absorption and enhances peripheral insulin sensitivity, promoting increased glucose uptake in muscle and adipose tissue. The drug does not stimulate insulin secretion, which contributes to its low risk of hypoglycemia when used alone. These actions collectively improve overall glycemic control in patients with insulin resistance.

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

Common Side Effects

• Gastrointestinal upset: nausea, abdominal discomfort, or loss of appetite.
• Diarrhea: loose stools that may be watery.
• Metallic taste: transient alteration in taste perception.
• Vitamin B12 deficiency: reduced absorption leading to low levels over long‑term use.

Serious or Rare Side Effects

• Lactic acidosis: rare but potentially fatal accumulation of lactate.
• Severe hypoglycemia: when combined with insulin or secretagogues.
• Skin reactions: rash, erythema, or Stevens‑Johnson syndrome.

Before initiating Metformin Milpharm, healthcare professionals should consider several precautionary measures.

• Renal function assessment: evaluate eGFR and avoid use in severe renal impairment.
• Lactic acidosis risk: contraindicated in patients with significant hepatic disease or hypoxia.
• Alcohol consumption: limit intake to reduce risk of lactic acidosis.
• Pregnancy and lactation: discuss potential risks and benefits with the prescriber.
• Drug interactions: review concomitant medications for agents that may increase metformin levels.
• Store at ambient temperature: keep in original container, protect from moisture and heat.

Metformin Milpharm can interact with other medicines, affecting its efficacy or safety.

Major Interactions (Avoid)

• Iodinated contrast media: may precipitate renal dysfunction and increase lactic acidosis risk.
• Cimetidine: can raise metformin plasma concentrations.
• Nitrates: concurrent use may enhance hypotensive effects.

Moderate Interactions (Monitor Closely)

• Beta‑blockers: may mask symptoms of hypoglycemia.
• Thiazide diuretics: can attenuate glucose‑lowering effect.
• ACE inhibitors or ARBs: require monitoring of renal function and electrolytes.
