Bacterial conjunctivitis in dogs is usually secondary to other underlying dysfunction e.g. poor eyelid anatomy, tear-film abnormalities etc. Most commonly isolated bacteria = Staphylococcus pseudintermedius; other organisms include streptococci.
Chlamydophila felis is the organism isolated most often in the UK. Staphylococcus spp., Pastuerella multocida and Mycoplasma spp. can also be involved. Isolated Viral infection (herpesvirus, calicivirus) is an important cause in cats.

Diagnosis and Monitoring

The clinical signs of bacterial conjunctivitis are:
  • Red conjunctiva
  • Conjunctival chemosis (swelling)
  • Ocular discharge
  • Ocular discomfort


  • One drop applied in conjunctival sac once or twice daily.
  • Treatment should be continued for at least 24 hours after the eye has returned to normal If no response after 5 days, re-evaluate diagnosis.
  • If an animal has one infected eye, it may be advisable to treat both eyes to prevent cross infection. In such cases, it is better to treat the uninfected eye first to avoid transferring infection via the tube nozzle.


Allergic reactions or hypersensitivity to the active substance or the excipients might occur. Discontinue use if hypersensitivity to the product develops.
