I have found a small white pill with CIBA 16 on one side and blank on the other. Can anyone help me identify this pill and tell me what it is used for? Thanks so much.
Sounds like it could be a sustained released Ritalin 20MG.
CIBA is short for the company Ciba-Geigy that makes it. http://ritalin.drugs.com/ https://www.drugs.com/ritalin.html
