How Long can a person stay on Low Dose Naltrexone (LDN)?
A person can stay on LDN long-term for many years and perhaps a lifetime. The optimal dose is decided by the health care provider writing the prescription. There is now a wide range of doses that are used from 0.25 mg to 4.5 which is considered in the average range. Above 6 mg is probably not low-dose any longer.
