I am looking for info on naltrxone use for problems related to constipation from being on dilaudid rlated to chronic pain from an auto accident.I have been hospitalized several times for dire constipation and my Dr. just put me on a baby dose of naltrexone to assist with this problem.He told me it does something to the end of the colon,and he told me to google it for more info but am at a loss as I can find no info on it for this use.I can only find breast cancer research using it ,and using it for alcoholism and opiate use to detox patients.I would appreciate any info you have.Thanks
