I never received suppositories from my mom, just the "regular" enemas.
I don't think I would use suppositories now either, unless prescribed by my physician.
I do recall a few years ago I was on a cruise ship, and came down with flu-like symptoms. It was a foreign cruise line, and when I went to the infirmary to see the nurse she told me they had a medication for my symptoms, and since we were not in U.S. waters they could use it. I found this interesting at the time. She asked me if I would prefer an injection, or suppository. I opted for the injection. I have to admit that in less than 24 hours I was feeling good as new! :) This was obviously some drug that our country had yet to approve.
My partner and I were able to continue on the cruise, enjoying every minute of it. :)
