I would advise you to give your extra meds to your nurse or pharmacy to dispose of properly.

I am frequently changing and adding new medications, which can quickly make a supply of OD meds. I usually hold onto these meds, to hold onto that option honestly. A couple of weeks ago, I decided that it would be best to give them to my nurse instead. She filled my weekly med case and was about to leave & I asked if she would take the meds for me. Sure ~ all done. Nice and easy!
