Metformin Tablets BP 500 Mg Tablet

What is Metformin Tablets BP 500 Mg Tablet?

Metformin Tablets BP 500 mg contain metformin, an oral antidiabetic medicine belonging to the biguanide class. The tablets are used as part of the management of type 2 diabetes mellitus, together with appropriate dietary and lifestyle measures. Metformin helps improve blood glucose control primarily by reducing hepatic glucose production and improving insulin sensitivity.

Uses / Indications

Metformin 500 mg tablets may be used in the management of:

• Type 2 diabetes mellitus
• Inadequate blood glucose control with diet and lifestyle measures alone
• Type 2 diabetes in combination with other antidiabetic medicines when clinically indicated

The specific treatment regimen depends on the patient’s clinical condition, blood glucose control, kidney function and approved product information.

Benefits

• Helps improve blood glucose control in type 2 diabetes.
• Reduces excessive glucose production by the liver.
• Improves the body’s sensitivity to insulin.
• Can be used as part of combination antidiabetic therapy when clinically appropriate.
• Provides a 500 mg oral tablet strength for prescribed treatment regimens.

Side Effects

Common Side Effects

Possible adverse effects may include:

• Nausea
• Vomiting
• Diarrhoea
• Abdominal discomfort
• Abdominal pain
• Loss of appetite
• Changes in taste

These gastrointestinal effects may be more noticeable when treatment is initiated or the dose is increased.

Less Common or Serious Side Effects

Clinically important reactions may include:

• Vitamin B12 deficiency with prolonged use
• Significant changes in kidney function
• Hypoglycaemia, particularly when metformin is combined with other glucose-lowering medicines
• Lactic acidosis, a rare but potentially serious adverse reaction

Urgent medical attention is required if symptoms suggestive of severe metabolic disturbance, such as marked weakness, breathing difficulty, persistent vomiting, unusual drowsiness or severe abdominal discomfort, occur.

How Does It Work?

Metformin

Metformin is a biguanide antidiabetic medicine. It primarily reduces hepatic glucose production and also improves peripheral insulin sensitivity, which can increase glucose uptake and utilisation by tissues.

Metformin does not generally stimulate pancreatic insulin secretion, so when used alone it has a relatively low risk of causing hypoglycaemia.

Dosage Guidelines

The appropriate dose and treatment duration depend on:

• Blood glucose levels
• Treatment response
• Kidney function
• Age
• Tolerability
• Other antidiabetic medicines
• The overall diabetes management plan

The exact dose and treatment duration should follow the approved product information and the recommendation of a qualified healthcare professional.

For oral tablets:

• Take exactly as prescribed.
• Take with meals where directed to help improve gastrointestinal tolerability.
• Swallow the tablet with sufficient water unless otherwise directed.
• Follow the prescribed treatment schedule.
• Do not alter the dose without professional advice.

Kidney function should be assessed when clinically appropriate because metformin is substantially eliminated through the kidneys.

When Not to Use

Metformin should generally not be used in patients with:

• Known hypersensitivity to metformin or any component of the formulation
• Severe renal impairment
• Acute or chronic conditions associated with significant tissue hypoxia where metformin may be contraindicated
• Metabolic acidosis, including diabetic ketoacidosis

Additional medical assessment may be required in patients with significant liver disease, dehydration, severe infection or other conditions that may increase the risk of lactic acidosis.

Drug / Product Interactions

Clinically relevant interactions may occur with medicines that affect kidney function, glucose control or metformin exposure.

Particular attention may be required when metformin is used with:

• Insulin and other antidiabetic medicines
• Certain medicines that can affect renal function
• Cationic medicines eliminated through renal tubular secretion
• Corticosteroids and other medicines that may alter blood glucose
• Iodinated contrast media in situations where temporary interruption may be required according to clinical guidance

Patients taking multiple medicines should inform their healthcare professional before starting metformin.

Safety Advice

Overdose

If an overdose is suspected, seek immediate medical attention or contact an appropriate poison-control or emergency medical service.

Metformin overdose can result in serious metabolic complications, including lactic acidosis.

Missed Dose

Take the missed dose when remembered unless it is nearly time for the next scheduled dose. If the next dose is due soon, skip the missed dose and continue with the regular schedule. Do not double the next dose unless specifically instructed by a healthcare professional.

Pregnancy

Metformin use during pregnancy should be based on appropriate medical assessment and the approved treatment information.

Breastfeeding

Metformin can pass into breast milk. The potential benefits and risks should be discussed with a qualified healthcare professional before use during breastfeeding.

Children

Use in children and adolescents should follow the age-specific recommendations of the approved product information and healthcare professional guidance.

Elderly Patients

Older patients may require particular attention to kidney function because renal function can decline with age.

Renal Impairment

Kidney function should be assessed before and during treatment as clinically appropriate. Metformin may be contraindicated or require treatment modification in patients with significant renal impairment.

Hepatic Impairment

Patients with significant liver disease should inform their healthcare professional before treatment because severe hepatic impairment may increase the risk of metabolic complications.

General Instructions

• Take the medicine according to the prescribed schedule.
• Take with meals where directed.
• Swallow the tablet with sufficient water unless otherwise directed.
• Do not alter the dosage without professional advice.
• Maintain the recommended dietary and lifestyle measures for diabetes management.
• Keep the medicine in its original packaging where appropriate.
• Do not share prescription medicines with other people.
• Follow the approved product information and healthcare professional’s instructions.

Special Dietary / Lifestyle Tips

Metformin treatment is generally used alongside appropriate dietary and lifestyle measures for diabetes management.

Patients should follow the individualized dietary, physical activity and blood glucose monitoring recommendations provided by their healthcare professional.

Alcohol intake may require particular caution because excessive alcohol consumption can increase the risk of metabolic complications associated with metformin.

Comparison with Other Treatments

Metformin belongs to the biguanide class of antidiabetic medicines. Other treatments for type 2 diabetes include sulfonylureas, DPP-4 inhibitors, SGLT2 inhibitors, GLP-1 receptor agonists, insulin and other glucose-lowering medicines.

These treatments differ in their mechanisms, administration methods, effects on blood glucose, adverse-effect profiles and clinical considerations. The choice of treatment depends on factors such as glycaemic control, kidney function, cardiovascular and metabolic considerations, tolerability and the overall treatment plan.

Precautions & Warnings

• Confirm any history of hypersensitivity to metformin or formulation components.
• Kidney function should be assessed before and during treatment where appropriate.
• Use caution in situations involving dehydration, severe infection or significant tissue hypoxia.
• Inform the healthcare professional before procedures involving iodinated contrast media.
• Avoid excessive alcohol consumption during treatment.
• Long-term treatment may be associated with vitamin B12 deficiency in some patients.
• Patients taking other glucose-lowering medicines may require monitoring for hypoglycaemia.
• Seek medical attention if severe weakness, breathing difficulty, persistent vomiting, unusual drowsiness or other symptoms suggestive of lactic acidosis occur.
• Do not discontinue prescribed diabetes treatment without professional advice.
