Metronidazole Tablets BP 250 Mg Tablet

What is Metronidazole Tablets BP 250 Mg Tablet?

Metronidazole Tablets BP 250 mg contain metronidazole, a nitroimidazole antimicrobial agent. The tablets are used in the treatment of susceptible anaerobic bacterial and protozoal infections. Metronidazole acts against susceptible microorganisms by interfering with their DNA, making it useful across several gastrointestinal, genitourinary and other clinically indicated infections.

Uses / Indications

Metronidazole 250 mg tablets may be used in the treatment or management of susceptible infections, including:

• Anaerobic bacterial infections
• Certain protozoal infections
• Trichomoniasis
• Giardiasis
• Amoebiasis
• Certain anaerobic gastrointestinal infections
• Other susceptible infections where metronidazole therapy is indicated

The specific indication depends on the causative organism, infection site, clinical condition and approved product information.

Benefits

• Provides antimicrobial activity against susceptible anaerobic bacteria.
• Has activity against several susceptible protozoal organisms.
• Available as an oral tablet formulation.
• Can be used for a range of clinically indicated anaerobic and protozoal infections.
• Provides a 250 mg strength for prescribed treatment regimens.

Side Effects

Common Side Effects

Possible adverse effects may include:

• Nausea
• Vomiting
• Diarrhoea
• Abdominal discomfort
• Loss of appetite
• Metallic or unpleasant taste
• Headache
• Dizziness

Less Common or Serious Side Effects

Clinically important reactions may include:

• Peripheral neuropathy, particularly with prolonged or repeated treatment
• Seizures or other neurological effects
• Severe skin reactions
• Hypersensitivity or allergic reactions
• Abnormal liver function

• Darkening of urine

Medical attention should be sought if severe neurological symptoms, significant allergic reactions, severe skin reactions or other serious symptoms occur.

How Does It Work?

Metronidazole

Metronidazole is a nitroimidazole antimicrobial agent. In susceptible anaerobic microorganisms and protozoa, it is converted into reactive metabolites that interact with microbial DNA. This damages DNA and interferes with nucleic acid synthesis, ultimately inhibiting the growth or survival of susceptible organisms.

Its activity is particularly relevant against anaerobic bacteria and certain protozoal pathogens.

Dosage Guidelines

The appropriate dose and treatment duration depend on:

• Type and location of infection
• Causative organism
• Severity of infection
• Age
• Liver function
• Kidney function
• Other medicines
• Treatment response

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.
• Swallow the tablet with sufficient water unless otherwise directed.
• Follow the prescribed treatment schedule.
• Complete the prescribed course unless instructed otherwise by a healthcare professional.
• Do not crush, split or chew the tablet unless permitted by the approved product information.

When Not to Use

Metronidazole should generally not be used in patients with:

• Known hypersensitivity to metronidazole, other nitroimidazole derivatives or any component of the formulation
• Certain serious neurological conditions where use is contraindicated according to the approved product information

Metronidazole should also be used with appropriate caution in patients with significant liver disease, a history of blood disorders or neurological disorders.

Drug / Product Interactions

Clinically relevant interactions may occur with several medicines.

Particular attention may be required when metronidazole is used with:

• Warfarin and other oral anticoagulants
• Lithium
• Disulfiram
• Certain anticonvulsants
• Medicines that affect hepatic drug metabolism
• Other medicines with potential neurological or hepatic effects

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

Safety Advice

Overdose

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

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

Metronidazole use during pregnancy should be based on the specific clinical indication, approved product information and appropriate medical assessment.

Breastfeeding

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

Children

Paediatric use should follow age- and indication-specific recommendations in the approved product information and healthcare professional guidance.

Elderly Patients

Older patients may require appropriate clinical assessment, particularly where liver function, neurological effects or multiple medicines are relevant.

Renal Impairment

Patients with significant renal impairment should inform their healthcare professional. Dose or treatment considerations may depend on the degree of renal dysfunction and the clinical indication.

Hepatic Impairment

Patients with significant hepatic impairment may require careful assessment because metronidazole is substantially metabolised in the liver.

Alcohol

Alcoholic beverages should generally be avoided during metronidazole treatment and for the period specified in the approved product information after treatment, because concurrent use may cause an unpleasant reaction.

General Instructions

• Take the medicine according to the prescribed schedule.
• Swallow the tablet with sufficient water unless otherwise directed.
• Complete the prescribed antimicrobial course unless advised otherwise by a healthcare professional.
• Avoid alcohol during treatment and for the appropriate period afterward as stated in the approved product information.
• Do not alter the dosage without professional advice.
• Keep the medicine in its original packaging where appropriate.
• Do not share prescription medicines with other people.

Special Dietary / Lifestyle Tips

No specific dietary restriction is generally required unless advised by a healthcare professional.

Alcohol should be avoided during metronidazole treatment and for the appropriate period after treatment as specified in the approved product information.

Comparison with Other Treatments

Metronidazole belongs to the nitroimidazole class and has activity against susceptible anaerobic bacteria and certain protozoa. Other antimicrobial medicines have different mechanisms of action, activity spectra and clinical indications.

The selection of an antimicrobial depends on factors such as the suspected or confirmed causative organism, infection site, susceptibility, severity, patient-specific factors and approved treatment indications.

Precautions & Warnings

• Confirm any history of hypersensitivity to metronidazole or other nitroimidazole medicines.
• Avoid alcohol during treatment and for the appropriate period afterward as specified in the approved product information.
• Use cautiously in patients with significant liver disease.
• Inform the healthcare professional about any history of neurological disorders.
• Prolonged or repeated treatment may require clinical monitoring.
• Seek medical attention if numbness, tingling, weakness, seizures or other significant neurological symptoms develop.
• Inform the healthcare professional if taking anticoagulants such as warfarin.
• Use during pregnancy or breastfeeding should be based on appropriate professional assessment.
• Complete the prescribed antimicrobial treatment unless instructed otherwise.
