7. Side Effects

Common Side Effects

Reported adverse effects associated with azithromycin may include:

• Nausea and vomiting.

• Diarrhoea or abdominal discomfort.

• Infusion-site pain or inflammation.

• Changes in liver enzyme measurements.

The adverse-effect profile varies with the patient, treatment regimen and product presentation.

Less Common or Serious Side Effects

Clinically important risks may include:

• Serious allergic reactions: Including angioedema or anaphylaxis.

• Heart rhythm abnormalities: Including QT prolongation and potentially serious arrhythmias in susceptible patients.

• Liver injury: Including rare serious hepatic reactions.

• Severe antibiotic-associated diarrhoea: Including Clostridioides difficile-associated diarrhoea.

• Hearing impairment: Reported in association with azithromycin, particularly in certain clinical circumstances.

Suspected serious reactions require prompt medical assessment. Review the approved prescribing information for the full safety profile.

8. How Does It Work?

Azithromycin is a macrolide antibiotic that acts by binding to the 50S subunit of susceptible bacterial ribosomes. This interferes with bacterial protein synthesis and inhibits bacterial growth. Its activity depends on the susceptibility of the organism and the concentration achieved at the infection site.

Azithromycin does not treat viral infections such as influenza or the common cold. Appropriate antibiotic selection should consider clinical assessment and microbiological susceptibility information where available.

9. Dosage Guidelines

Dosage must be determined by a qualified healthcare professional in accordance with the approved product information.

Factors affecting the prescribed regimen include:

• The type and severity of infection.

• The susceptibility of the causative organism.

• The patient’s age and medical history.

• Relevant cardiac and hepatic risk factors.

• The prescribed route and duration of treatment.

• Whether a transition to oral azithromycin is appropriate.

The stated 500 mg vial strength is not necessarily the complete treatment dose or duration. Do not assume a universal dosage schedule, reconstitution volume, diluent or infusion rate for every product.

Azithromycin injection requires professional preparation and administration. Follow the approved instructions for the exact formulation.

10. When Not to Use

Azithromycin should not be used in patients with a known serious hypersensitivity to azithromycin, erythromycin or other relevant macrolide or ketolide antibiotics, as specified in the applicable product information.

Additional clinical assessment is important for patients with:

• A history of significant QT prolongation or serious cardiac rhythm abnormalities.

• Conditions that increase the risk of electrolyte disturbances or arrhythmias.

• Previous azithromycin-associated cholestatic jaundice or hepatic dysfunction, where covered by the product warnings.

• Significant liver disease or other relevant medical conditions.

• Other contraindications documented in the approved prescribing information.

The exact contraindications must be checked against the product’s authorised labelling.

11. Drug / Product Interactions

Important interaction considerations include:

• Warfarin: Concurrent use may require monitoring of coagulation parameters.

• Medicines that prolong the QT interval: May increase the risk of potentially serious heart rhythm abnormalities.

• Nelfinavir: May increase azithromycin exposure and warrant additional monitoring.

• Other medicines affecting cardiac rhythm or electrolytes: Require careful clinical assessment.

• Other medicines with relevant hepatic or metabolic effects: Should be reviewed against the complete prescribing information.

Interaction significance varies by medicine and patient. Healthcare professionals should review all current medicines before treatment.

Do not mix azithromycin injection with other medicines or infusion solutions unless compatibility has been established in the approved product documentation.

12. Safety Advice

• Use only under appropriate medical supervision.

• Confirm the product name, strength, batch number and expiry date before preparation.

• Inspect the vial and packaging for damage.

• Review the patient’s allergy history and relevant medical conditions.

• Assess cardiac risk factors and concurrent medicines where appropriate.

• Follow the approved preparation and intravenous administration instructions.

• Monitor for hypersensitivity, infusion-related reactions and other clinically significant adverse effects.

• Use antibiotics only when clinically indicated to help limit antimicrobial resistance.

• Do not use the medicine for self-medication.

13. General Instructions
