Indications & Clinical Uses

Metformina Ciclum is a biguanide antidiabetic that lowers blood glucose by acting on hepatic and peripheral pathways.

  • Type 2 diabetes mellitus: improves glycaemic control and reduces HbA1c levels.
  • Prediabetes (impaired fasting glucose): delays progression to overt diabetes.
  • Polycystic ovary syndrome (off‑label): helps restore regular ovulation and improve insulin sensitivity.

How It Works

  • Metformin reduces hepatic gluconeogenesis and increases peripheral glucose uptake by activating AMP‑activated protein kinase (AMPK). This leads to decreased liver glucose output and enhanced insulin‑mediated glucose utilization in muscle and adipose tissue, resulting in lower circulating blood glucose levels.

Side Effects

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

Common Side Effects

  • Nausea: mild to moderate stomach upset.
  • Diarrhoea: loose stools, especially during treatment initiation.
  • Metallic taste: transient alteration of taste perception.
  • Abdominal discomfort: cramping or bloating.
  • Weight loss: modest reduction in body weight.

Serious or Rare Side Effects

  • Lactic acidosis: life‑threatening metabolic acidosis, requires immediate medical attention.
  • Severe skin reactions: such as Stevens‑Johnson syndrome or toxic epidermal necrolysis.
  • Hepatotoxicity: abnormal liver function tests or hepatitis.
  • Vitamin B12 deficiency: may develop with long‑term use.
  • Hypoglycaemia: rare when combined with other glucose‑lowering agents.

Precautions & Warnings

Metformina Ciclum should be used with careful clinical monitoring to minimise risks.

  • Renal function assessment: avoid or adjust dose in patients with impaired kidney function.
  • Hepatic function monitoring: use cautiously in liver disease.
  • Blood glucose monitoring: regularly check glucose to avoid hypoglycaemia when combined with other agents.
  • Elderly patients: start with lower dose and titrate slowly.
  • Heart failure: contraindicated in severe, unstable heart failure.
  • Store at ambient temperature: keep in the original packaging, protect from moisture and heat.

Avoid Interactions

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

Major Interactions (Avoid)

  • Iodinated contrast agents: increase risk of renal impairment and lactic acidosis.
  • Alcohol: potentiates lactic acidosis risk.
  • Cimetidine: may raise metformin plasma concentrations.

Moderate Interactions (Monitor Closely)

  • Beta‑blockers: may mask hypoglycaemia symptoms.
  • Diuretics: can affect renal clearance of metformin.
  • ACE inhibitors or ARBs: monitor renal function and electrolytes.
  • NSAIDs: may impair renal function, increasing metformin exposure.
  • Calcium channel blockers: occasional reports of altered glucose control.

Frequently Asked Questions

Metformina Ciclum contains metformin hydrochloride and is prescribed to improve blood glucose control in adults with type 2 diabetes mellitus. It may also be used off‑label for conditions such as prediabetes or polycystic ovary syndrome, where insulin resistance is a key factor.

Metformin primarily activates AMP‑activated protein kinase (AMPK), which suppresses hepatic glucose production and enhances peripheral glucose uptake. By reducing liver‑derived glucose and improving insulin sensitivity in muscle and fat tissue, it helps lower overall blood sugar levels.

The exact dose of Metformina Ciclum is determined by the prescribing clinician based on the individual’s renal function, glycaemic targets, and tolerance. Dosage adjustments are made during treatment to achieve optimal blood glucose control while minimizing side effects.

Metformin crosses the placenta and is classified as a pregnancy‑category B medication in many regions, meaning it may be used when the potential benefit outweighs risk. However, safety data are limited, and the drug should only be used under close medical supervision. It is excreted in breast milk, so breastfeeding mothers should consult their physician before continuing therapy.

To place an order, submit an enquiry on the product page at gnhindia.com with the required quantity. GNH India supplies hospitals, pharmacies and procurement teams worldwide, verifies trade or institutional credentials, and then provides pricing, availability, shipping details (including any cold‑chain requirements) and necessary import documentation.

Metformina Ciclum belongs to the biguanide class, which differs from sulfonylureas, DPP‑4 inhibitors, or SGLT2 inhibitors. Unlike insulin‑secretagogues, metformin does not stimulate insulin release, reducing the risk of hypoglycaemia. It is generally weight‑neutral or may cause modest weight loss, and it has a well‑established safety profile for long‑term cardiovascular outcomes.

Metformina Ciclum should be stored at ambient temperature, below 25 °C, in its original container to protect it from moisture and light. Keep the product out of reach of children and avoid storing it in bathrooms or near heat sources.

Metformina Ciclum is taken orally, usually with meals to reduce gastrointestinal discomfort. The tablets are swallowed whole with a glass of water. Patients should follow the dosing schedule prescribed by their healthcare provider and not crush or chew the tablets unless specifically instructed.

The most serious risk is lactic acidosis, a rare but potentially fatal condition that can occur in patients with severe renal impairment, liver disease, or excessive alcohol intake. Other serious concerns include severe skin reactions such as Stevens‑Johnson syndrome and significant vitamin B12 deficiency with long‑term use.

Metformina Ciclum is contraindicated in patients with severe renal impairment (eGFR < 30 mL/min/1.73 m²), acute or chronic metabolic acidosis, including diabetic ketoacidosis, and in those with known hypersensitivity to metformin or other biguanides. Caution is also advised for individuals with unstable heart failure.
