Please don’t do this with unwanted medications - waste water treatment plants and home septic systems are not set up to remove pharmaceutical compounds from waste water, and they end up in our surface and drinking water. Antibiotics, like the drug the OP is trying to get rid of, can also harm the treatment system itself by killing off bacteria and other microbes.
If you don’t have a local household hazardous waste program that will accept it, here are the federal guidelines for unwanted medication disposal.
