Good question. I had to call my doctor to find out where to dispose of the needles and he suggested going to the pharmacy and puchasing one of those plastic red bins that they use in their offices to dispose of the needles. When I asked at the pharmacy, the Phamacist told me to use an empty, plastic detergent bottle. Made sense to me. I still unscew the needles and put them in the syringe, upside down, and then put the plunger back in, then I put them in the tide bottle. Any leftover pills that I can't take, or react badly to, or don't react at all.....etc. my pharmacist will safely dispose of them for me.
