Your husband is right, mainstream medicine has never encouraged it but grass-roots word-of-mouth is reaching a critical mass. It seems to be more effective with Crohn's than those with UC. But there aren't many side effects and it might be worth a shot.
www.lowdosenaltrexone.org/gazorpa/History.htmlNaltrexone in substantially lower doses (Low Dose Naltrexone) is showing great promise as a treatment for multiple sclerosis, Crohn’s disease, AIDS, rheumatoid arthritis, celiac disease, CFIDS, lupus, and certain forms of cancer.
Unfortunately, obtaining FDA approval for LDN will not be a straightforward process. Since naltrexone is now a generic drug, no pharmaceutical company currently holds exclusive manufacturing rights. No company is eager to fund an expensive clinical trial for a drug that will make them so little profit.
However, even without governmental approval or corporate support, LDN is gaining significant grass-roots attention among patients and doctors. The exchange of research information over the internet has greatly accelerated the recognition of the off-label use of LDN.
