I had to make the same decision that you are going through, in my case I was fortunate to not have the financial implications as I'm in the USA and I have good private insurance.
I read the Cochrane Review report about copaxone too, and I discussed this exact article with my neuro (a very renowned and well published MS specialist). He was adamant that in his practice he sees "responders" and "non-responders" to copaxone, in roughly 2 to 1 ratio. If you're a "responder" (2/3 chance so says my Doc), after a couple of years on the drug the annualized relapse rate drops way down to ~0.2 or so and in some cases some damage is actually reversed. The next piece of information is particularly compelling - the earlier in the disease you take copaxone, the more likely you'll be a responder.
His assertion is that the studies that the Cochrane Review referenced (which came out of Italy) were based on people who already had EDSS scores in the 2.5 to 3.5 range prior to initiating treatment. He concedes that he has seen in his practice that copaxone is often not the right drug for such people. But he firmly believed (and believes now) that for people with little to no present disability, it does help them alot. He also believes that the Cochrane Review selectively chose to ignore a couple of studies which would have shown copaxone in a more favorable light (remember, Cochrane is a meta-study, not a clinical trial publication itself).
I was skeptical, but went for it, esp since copaxone appeared to have the least invasive side effects of any of the CRAB drugs. Now here I am 13 months later and sure enough my followup MRI shows some moderate improvements in one area of the brain, and my neurological exam is a bit better. I have had no relapses in the 13 month time period. I have however had 3 IPIRs, unpleasant I can tell you for sure. I have not had any serious injection site reactions or any lipoatrophy (men usually don't get lipoatrophy).
For completeness I need to mention that I also take LDN (and have for nearly 5 yrs now), and extensive vitamins (Alpha Lipoic, Fish Oils, Trans Ferulic, Calcium Magnesium, B12, and a general multi vitamin). I followed this regimen alone without copaxone for nearly 4 yrs and had "several" new lesions according to MRI and 1 relapse.
You might it helpful to read the original post I made last year when I had to make this same decision --- http://www.thisisms.com/ftopict-4067.html
Only you and your wife can make this decision, I am only imparting one data point. Good luck with whatever you decide.
