What is this medicine used for?

  • This medicine prevents symptoms of allergic conjunctivitis (itchy, watery, red, irritated eyes). May take up to 4 weeks to see the full effects.


How does it work?

  • Pemirolast, if taken before coming in contact with the material that causes the allergy, blocks the allergic reaction by minimizing or preventing the eye's reaction to the allergen.


How is it best taken?

  • Separate each eye medicine by 5 minutes. Give one and wait 5 minutes before using the next.
  • Do not touch the bottle tip to eye, lid, or other skin.
  • This medicine is most effective if started before contact with the allergen.


What do I do if I miss a dose?

  • Instill a missed dose as soon as possible.
  • If it is almost time for the next dose, skip the missed one. Return to your regular schedule.
  • Do not instill a double dose or extra doses.
