3 Proper Usage

To use Neocidin properly, you must follow all instructions given by your doctor. The dropper is partially full, providing proper drop control during application. To use the eye drops, you have to start with clean hands. Tilt back your head and pull the lower eyelid away from the eye, forming a pouch. Drop the solution into the pouch and close your eyes gently.

Close your eyes for about 1 to 2 minutes to allow the solution “soak” the infection. Do not blink. If you feel the drop did not get into the eye properly, apply another drop. Wash hands immediately after application. Do not let the tip applicator come in contact with any surface. Cover the container and keep it tightly closed.


In treating eye infection in adults and children, apply 1 drop in each (affected) eye. Repeat application two to four times a day for 7-10 days. For serious eye infections, your doctor may advise applying one drop per eye every 15-30 minutes.

Missed dose

Take the missed dose as soon as possible. In case it is almost time for the next dose, skip the missed one and follow your regular dosing schedule.


Keep the medicine in an airtight container at normal room temperature. Keep it away from direct light, heat, and moisture. Do not let it freeze. Keep the medicine out of children’s reach. Throw away any outdated medicine or medicine that are not in use.
