Sorry for he bump but this is of interest to me and I have some info to add, also plan to add more in the near future. I think its a very important subject, seeing as constipation may be the most physically harmful effect of opioids to the human body. If we could keep it in check I would see opioids as being even more safe to use on a daily basis than toxic drugs like alcohol that are legal, but not addictive so society has deemed them acceptable. But someone who drinks every day, compared to someone who uses opioids everyday (especially if they do not use needles or if they do are safe and use micron filters and new needles as often as possible, but we know addicts often don't have the money, patience, desire, or means to take these precautions)
I tried taking a 2 mg naloxone vial and messed up so only got (tops) .5 mg of the solution ingested orally. That day I woke up and within 30 minutes and a cup of coffee I had a very good bowel movement. Best I've had in months I would say. So it seems to me that it definitely has the potential to be useful in treating constipation. I also remember when I would swallow the saliva from Suboxone when I was taking Subs, that it seemed I would get some anti-constipation effect from that, so that is why I decided to try it with a vial of pure naloxone and it seemed to help. I have noticed if I swallow the spit from the Sub everyday when I am using them daily, that it gives me headaches and nausea, so I only do it if I am backed up. Its not something I think is good to be ingesting on a daily basis but worth it if it clears out the bowels after days(or weeks in some people's cases) of constipation.
I was wondering if it was just a matter of waiting on taking my morning dose so I took some benzos to help feel a little better and waited this morning and did not get the relief I received from the day I took the naloxone in the morning, which further makes me believe the naloxone was the reason I was able to have a normal bowel movement. Both times I woke up, waited about 15-20 minutes, drank a 12 ounce cup of coffee and today I finised the coffee and I had a very small and compact bowel movement. The other day when I took the naloxone, I also had a copacted and small (but larger than today's) bowel movement, like after one sip of coffee, then a little after halfway through the coffee I all of sudden needed to go and it was a very normal BM, not even loose stool surprisingly.
That was about a week ago and since then I have had nothing but small, compacted BMs. So tomorrow morning I am gonna try a full 2 mg of naloxone and see how that works, hopefully clears me out because its Thanksgiving and it'd be a good day to flush the system.
