What are the benefits/risks of taking low dose naltrexone (ldn) to treat multiple sclerosis?

Risk: liver tóxic: In excessive amount may be seriously toxic to the liver ( not in usual prescribed dosis). Since there is nothing proven to cure multiple sclerosis you should ask whoever recommended it what is suppose to do. It is considered an opium antagonist. Hopefully your neurologist is aware. Do not take it unless supervised by someone experienced in using it for ms.

Disappointing: This chemical, unfortunately, has entered the folklore of how to treat ms by variant approaches. There is no objective evidence of any significant value, and indeed, may be counter-productive by avoiding drugs that really are of value, such as tysabri (natalizumab) or gilenya.
