Emedastine is employed to alleviate redness, itching, and swelling of the eyes caused by allergies, specifically allergic conjunctivitis. As an antihistamine, this medication operates by blocking certain natural substances, specifically histamines, which are responsible for inducing allergic symptoms.

Uses and Dosage

To apply eye drops, start by washing your hands thoroughly. To prevent contamination, avoid touching the dropper tip, and ensure it does not come into contact with your eye or any other surfaces.

If you wear contact lenses, remove them before using this medication, as it contains a preservative that can be absorbed by the lenses. Wait at least 10 minutes after applying the medication before reinserting the contact lenses. If your eyes are red, refrain from wearing contact lenses.

Apply this medication in the affected eye(s) according to your doctor’s instructions, typically up to 4 times a day.

To administer the eye drops, the following steps should be followed:

  1. Thoroughly wash hands with soap and water.
  2. Do not allow the dropper tip to touch the eye or any other surface, and ensure that it is kept clean.
  3. Tilt the head back and pull down the lower lid of the eye using the index finger to form a pocket.
  4. Hold the dropper as close to the eye as possible without making contact, and brace the remaining fingers against the face.
  5. Squeeze the dropper gently to instill a single drop in the pocket created by the lower eyelid while looking upwards.
  6. Remove the index finger from the lower eyelid and keep the eye closed for 2-3 minutes while tilting the head down.
  7. Apply gentle pressure to the tear duct using a finger.
  8. Use a tissue to wipe off any excess liquid from the face.
  9. Wash hands to remove any residual medication.
