Can LDN be combined with other medications, drugs, vitamins or food supplements?
This is from ldnscience.org
"...LDN should not be taken at the same time with opiate-type drugs as it will stop them from working for a number of hours. With regards to other medications/drugs/vitamins in the clinical trials conducted to date, no problems have been seen when LDN was combined with other medications being taken by the studies’ participants. Therefore at this moment, there is no known reason to avoid taking LDN with any medication/drug/vitamin/supplement other than opiate-type drugs usually used for treating pain..."
BTW, LDN is low dose naltrexone, and has been used successfully in treating UC and Crohn's patients.
