Regarding medications, when my mother went into a nursing home, I couldn't give them to the nursing home. Liability, I suppose. I took them to our local CVS pharmacy and they said they would dispose of them. I encourage others to take them to a pharmacy to dispose of any old or unneeded medications, OTC or prescription.
