Moxifix 400 is used for the treatment of:
- Bacterial eye infections, including bacterial conjunctivitis
Moxifix 400 contains moxifloxacin, a broad-spectrum fluoroquinolone antibiotic used to treat bacterial infections. The eye drop formulation is commonly prescribed for bacterial eye infections, while oral formulations are used for various systemic bacterial infections. It works by stopping the growth and multiplication of bacteria, helping clear the infection and relieve associated symptoms.
Moxifloxacin may also be prescribed for:
- Community-acquired pneumonia
- Acute bacterial sinusitis
- Acute exacerbations of chronic bronchitis
- Skin and soft tissue infections
- Complicated intra-abdominal infections
- Typhoid fever
How It Works
Moxifloxacin inhibits bacterial enzymes known as DNA gyrase (topoisomerase II) and topoisomerase IV, which are essential for bacterial DNA replication, repair, and cell division. By blocking these enzymes, it prevents bacteria from multiplying and ultimately eliminates the infection.
Dosage and Administration
Eye Drops
- Use exactly as prescribed by your doctor.
- Wash your hands before application.
- Hold the dropper close to the eye without touching the eye or surrounding surfaces.

Helpful Tips
- Apply gentle pressure to the inner corner of the eye for about one minute after instillation.
- Wait at least 5–10 minutes before using another eye medication.
- Do not wear contact lenses until the infection has completely resolved.
- Discard the bottle within 4 weeks of opening unless otherwise instructed.
