What are Optilast Eye Drops?

Optilast Eye Drops are used to relieve and prevent the symptoms of hay fever (seasonal allergic conjunctivitis) and for the relief of eye symptoms associated with pet allergies and other allergies (non-seasonal allergic conjunctivitis).

Optilast Eye Drops contain azelastine hydrochloride and benzalkonium chloride to prevent itchy, red, watery eyes.

  • For seasonal allergic conjunctivitis, Optilast Eye Drops can be used in adults and children aged 4 and over.
  • For non-seasonal allergic conjunctivitis, Optilast Eye Drops can be used in adults and children aged 12 and over.

How do Optilast Eye Drops work?

Optilast Eye Drops can be used to treat the symptoms of seasonal and non-seasonal allergic conjunctivitis in adults and children.

They contain the active ingredient azelastine hydrochloride, a type of medicine known as an antihistamine.

The body produces histamines in response to allergens such as pet fur or pollen. This causes a chain reaction resulting in inflammation and red, watery, itchy eyes. Azelastine blocks the body's histamine receptors to prevent this reaction occurring.

When Optilast Eye Drops are placed into the eye, they can relieve symptoms within 15 to 30 minutes. 

How to use Optilast Eye Drops

  • Wash your hands before using the drops
  • Put 1 drop into each eye twice a day
  • This can be increased to 1 drop in each eye up to 4 times a day, if needed
  • You can also use Optilast Eye Drops to prevent hay fever symptoms before exposure to pollen
  • You can use these drops for up to 6 weeks at a time
  • If symptoms don't improve within 48 hours, consult your doctor
