Azithromycin 250 mg is an antibiotic commonly used in Australia to treat various bacterial infections. It belongs to the macrolide class and works by stopping bacteria from growing. It is prescribed for respiratory tract infections, such as bronchitis, pneumonia, and sinusitis, throat infections like tonsillitis and pharyngitis, certain skin infections, and some sexually transmitted infections, including uncomplicated chlamydia. Azithromycin is ineffective against viral infections, so it should not be used for colds or the flu. In Australia, it is available only with a doctor’s prescription, and it is important to follow the prescribed dosage and complete the full course to prevent antibiotic resistance and ensure effective treatment.
