Ampicillin Tablets Film Coated- 500 Mg Tablet

What is Ampicillin Tablets Film Coated- 500 Mg Tablet?

Ampicillin Tablets Film Coated 500 mg is an oral antibacterial formulation containing ampicillin, a penicillin-class antibiotic. Each film-coated tablet contains 500 mg of ampicillin and is used for the treatment or management of susceptible bacterial infections when antibacterial therapy is clinically indicated. Use should follow the approved product information and healthcare professional’s advice.

Uses / Indications

Ampicillin 500 mg tablets may be used in the management of susceptible bacterial infections, depending on the approved indication and local prescribing information, including:

• Respiratory tract infections caused by susceptible bacteria
• Urinary tract infections caused by susceptible organisms
• Gastrointestinal infections caused by susceptible bacteria
• Skin and soft-tissue infections
• Certain other bacterial infections for which ampicillin is an appropriate antimicrobial option

The choice of ampicillin should be based on the suspected or confirmed causative organism, its susceptibility, infection site, and applicable clinical guidance.

Benefits

• Provides antibacterial activity against susceptible bacteria.
• Ampicillin belongs to the penicillin class of beta-lactam antibiotics.
• The 500 mg tablet provides an oral dosage form for appropriate treatment of susceptible bacterial infections.
• May be used when the causative organism is known or considered susceptible to ampicillin.
• Film-coated tablet formulation supports convenient oral administration.

Side Effects

Common Side Effects

Possible adverse effects may include:

• Nausea
• Vomiting
• Diarrhoea
• Abdominal discomfort
• Skin rash
• Headache

Less Common or Serious Side Effects

Clinically important reactions may include:

• Hypersensitivity or allergic reactions
• Urticaria or angioedema
• Severe skin reactions
• Antibiotic-associated colitis, including Clostridioides difficile-associated diarrhoea
• Changes in blood-cell counts with prolonged or intensive treatment
• Liver or kidney-related abnormalities in susceptible patients

Severe allergic reactions or persistent or severe diarrhoea require prompt medical assessment.

How Does It Work?

Ampicillin

Ampicillin is a beta-lactam antibacterial agent belonging to the penicillin group. It acts by binding to bacterial penicillin-binding proteins and interfering with the enzymes involved in bacterial cell-wall synthesis. This weakens the bacterial cell wall and can lead to bacterial cell death in susceptible organisms.

Its activity depends on the susceptibility of the infecting organism, and resistance can reduce or eliminate its antibacterial effectiveness.

Dosage Guidelines

The appropriate ampicillin dose and treatment duration depend on factors such as the type and severity of infection, the susceptibility of the causative organism, patient age, body weight, kidney function, and clinical response.

For oral tablets:

• Take exactly as prescribed by a qualified healthcare professional.
• Swallow the tablet with water according to the approved product instructions.
• Follow the prescribed dosing schedule consistently.
• Complete the prescribed course unless the healthcare professional advises otherwise.
• Do not alter the dose or treatment duration without professional advice.

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

Dose adjustment or additional monitoring may be required in patients with impaired renal function.

When Not to Use

Ampicillin should generally not be used in patients with a known serious hypersensitivity to ampicillin, penicillins, or other beta-lactam antibiotics where cross-reactivity is clinically relevant.

Medical advice is particularly important for patients with:

• Previous serious allergic reactions to penicillin or beta-lactam antibiotics
• Significant renal impairment
• A history of antibiotic-associated colitis
• Conditions requiring prolonged antibacterial treatment

Drug / Product Interactions

Clinically relevant interactions may occur between ampicillin and certain other medicines.

Particular attention may be required when ampicillin is used with:

• Probenecid
• Anticoagulants such as warfarin
• Other antibiotics with bacteriostatic activity, depending on the clinical situation
• Methotrexate
• Other medicines requiring monitoring during antibacterial treatment

Patients should inform their healthcare professional about all medicines, supplements, and other treatments they are taking before starting therapy.

Safety Advice

Overdose

If an overdose is suspected, seek immediate medical attention or contact an appropriate poison-control or emergency medical service. Symptoms and management depend on the amount taken and the patient’s clinical condition.

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

Ampicillin should be used during pregnancy when clinically indicated and following appropriate medical assessment.

Breastfeeding

Ampicillin may pass into breast milk. A healthcare professional should assess the potential benefits and risks before use during breastfeeding.

Children

Use in children should follow age-, weight-, infection-, and indication-specific recommendations in the approved product information.

Elderly Patients

Older patients may require particular attention to kidney function and other factors that can influence antibiotic treatment.

Renal Impairment

Dose adjustment may be necessary in patients with impaired renal function. The appropriate regimen should be determined according to renal function and the approved product information.

General Instructions

• Take the medicine exactly according to the prescribed schedule.
• Follow the approved product information and healthcare professional’s instructions.
• Do not stop antibacterial treatment or change the dosage without professional advice.
• Do not share antibiotics with other people.
• Complete the prescribed treatment course unless otherwise directed.
• Inform the healthcare professional about any previous serious antibiotic allergy.
• Seek medical advice if severe allergic symptoms or significant diarrhoea develops during or after treatment.

Special Dietary / Lifestyle Tips

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

Patients should maintain adequate fluid intake where clinically appropriate and follow the prescribed treatment schedule. Antibiotics should be used only when clinically indicated to support appropriate antimicrobial use.

Comparison with Other Treatments

Ampicillin is a penicillin-class beta-lactam antibiotic used against susceptible bacterial infections. Other antibacterial medicines may belong to different antibiotic classes and can differ in their antibacterial spectrum, resistance profile, pharmacokinetics, dosage requirements, and approved indications.

Selection of an antibacterial treatment depends on factors such as the suspected or confirmed organism, antimicrobial susceptibility, infection site and severity, patient characteristics, previous antibiotic exposure, and applicable clinical guidance.

Precautions & Warnings

• Confirm any history of allergy to penicillins or other beta-lactam antibiotics before use.
• Stop treatment and seek urgent medical attention if signs of a serious allergic reaction occur.
• Severe or persistent diarrhoea during or after antibiotic treatment should be medically assessed.
• Use ampicillin only for susceptible bacterial infections for which antibacterial treatment is appropriate.
• Unnecessary or inappropriate antibiotic use can contribute to antimicrobial resistance.
• Patients with renal impairment may require dose adjustment.
• Prolonged treatment may require appropriate clinical or laboratory monitoring.
• Follow the approved product information for contraindications, warnings, and precautions.

Can I Use It With Other Medicines?

Generally Compatible With

Use With Caution / Avoid

Professional advice is particularly important when ampicillin is used with:

• Probenecid
• Warfarin or other anticoagulants requiring monitoring
• Methotrexate
