The ointment, as Allysia B mentioned, is definitely easier to apply. You must request from. The practitioners don't seem to mention the availability.
The ointment also seemed to clear the infection up quicker than drops. It was also good to know that Pink eye is preventable and according to the doctor is harder to "catch" that many things which are contagious.
How to help prevent: regular hand washing. According to the doctor kids get pink more from touching things, like the floor, then touching or rubbing their eye. I now try and keep my child off floors in public places. Good luck.
