How Nefcoz Eye Drop works

Nefcoz Eye Drop is a combination of two medicines: naphazoline and phenylephrine. Nefcoz Eye Drop relieves eye itching/discomfort caused by seasonal allergies. Naphazoline is a sympathomimetic-alpha 1 medicine that also narrows the blood vessels in the eye, thereby reducing redness and swelling. Phenylephrine is a decongestant that tightens the blood vessels in the eye further reducing redness and irritation.

Quick tips

  • In case the dropper tip gets contaminated, squeeze out two or three drops straightaway onto some tissue and rinse the tip with salt water.
  • After applying Nefcoz Eye Drop, close your eyes, and place one finger at the corner of your eye. Apply gentle pressure for 1 to 2 minutes before opening your eyes. This will prevent the medication from draining out. Try not to blink or rub your eye.
  • Avoid wearing contact lenses until your doctor advises you that it is suitable for you to wear your lenses again.
