Proper use of Clear Eyes

Do not use naphazoline ophthalmic solution if it becomes cloudy or changes color.

Naphazoline should not be used in infants and children. It may cause severe slowing down of the central nervous system (CNS), which may lead to unconsciousness. It may also cause a severe decrease in body temperature.

Use this medicine only as directed. Do not use more of it, do not use it more often, and do not use it for more than 72 hours, unless otherwise directed by your doctor. To do so may make your eye redness and irritation worse and may also increase the chance of side effects.

To use:

  • First, wash your hands. With the middle finger, apply pressure to the inside corner of the eye (and continue to apply pressure for 1 or 2 minutes after the medicine has been placed in the eye). Tilt the head back and with the index finger of the same hand, pull the lower eyelid away from the eye to form a pouch. Drop the medicine into the pouch and gently close the eyes. Do not blink. Keep the eyes closed for 1 or 2 minutes to allow the medicine to be absorbed.
  • To keep the medicine as germ-free as possible, do not touch the applicator tip to any surface (including the eye). Also, keep the container tightly closed.

The amount of medicine that you take depends on the strength of the medicine. Also, the number of doses you take each day, the time allowed between doses, and the length of time you take the medicine depend on the medical problem for which you are using the medicine.

  • For ophthalmic solution (eye drop) dosage form: For eye redness: Adults—Use one drop not more often than every four hours. Children—Use is not recommended.
