Why is this medication prescribed?

Why is this medication prescribed? has been expanded.

Ophthalmic alcaftadine is used to relieve the itching of allergic pinkeye. Alcaftadine is in a class of medications called antihistamines. It works by blocking histamine, a substance in the body that causes allergic symptoms.

How should this medicine be used?

Ophthalmic alcaftadine comes as a solution (liquid) to instill in the eye. It is usually instilled in the affected eye(s) once a day. To help you remember to use alcaftadine, use it around the same time every day. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Use alcaftadine exactly as directed. Do not use more or less of it or use it more often than prescribed by your doctor.

To instill the eye drops, follow these steps:

  1. Wash your hands thoroughly with soap and water.
  2. Check the dropper tip to make sure that it is not chipped or cracked.
  3. Avoid touching the dropper tip against your eye or anything else; eye drops and droppers must be kept clean.
  4. While tilting your head back, pull down the lower lid of your eye with your index finger to form a pocket.
  5. Hold the dropper (tip down) with the other hand, as close to the eye as possible without touching it.
  6. Brace the remaining fingers of that hand against your face.
  7. While looking up, gently squeeze the dropper so that a single drop falls into the pocket made by the lower eyelid. Remove your index finger from the lower eyelid.
  8. Close your eye for 2 to 3 minutes and tip your head down as though looking at the floor. Try not to blink or squeeze your eyelids.
  9. Place a finger on the tear duct and apply gentle pressure.
  10. Wipe any excess liquid from your face with a tissue.
  11. If you are to use more than one drop in the same eye, wait at least 5 minutes before instilling the next drop.
  12. Replace and tighten the cap on the dropper bottle. Do not wipe or rinse the dropper tip.
  13. Wash your hands to remove any medication.
