First I want to say that Avonex is not dangerous. Every med out there has side effects, and you should know what they are, I agree. That does not mean that every patient will get them, or even one of them. It is required that any significant effects (more than placebo) be reported, but if you read these charts, you will find that relatively speaking, the incidence of effects is low.
Second, it is necessary to weigh the potential benefits against the negatives. For all of the CRAB drugs, the positives outweigh the negatives, in my opinion. Would you rather get manageable flu symptoms or be confined to a wheelchair? I know that's a pretty harsh assessment, but for some people, that's the reality.
Third, although liver function can be affected by the interferon class of DMDs (for a small minority) this can easily be monitored through blood tests. Very few patients have to be taken off the drug because of this, so that's not a reason not to give it a try. If necessary, the med can be stopped, and the patient can be switched to Copaxone. This is a rare occurence.
Fourth, LDN has not be shown to work against MS. It often makes people with various diseases feel better and have a better quality of life, which is a good thing, but it does not slow MS disease progression. The DMDs do. Your doctor is correct in not agreeing to this option.
Doctors have spent many years learning about all these factors. There is no reason to automatically assume a position of distrust. This is not to say that some docs aren't stinkers, because as we all know, there are plenty of those out there. But I urge you to rely on your doctor unless or until there is reason not to.
