First of all, before you come to any hasty decision regarding this drug, read the threads pertaining to:
Avonex, Capaxone, Betaserone and Rebif. Would that be a better alternative for you? Needles you inject yourself!!! daily or weekly? The cost is expensive. SideFX too?
Pop a small pill once a day. For the first 6 months, visit the clinic every 2 weeks, get one needle to suck out a few tubes of blood, pee every so often in a small bottle, and do some math, coordination and walking tests every 6 weeks at first. Then it goes to 4, then 6 weeks for the blood tests.
Small price to pay, especially if you look at the alternatives.
They monitor you very closely, and if there are any changes for the worse, you will be notified almost immediately, and looked after.
Sometimes the doctors can determine by your blood tests whether you are on the placebo or not, but easy for women patients and very difficult for men patients. Don't bother getting the pill analyzed by an independent lab...the cost, and whether they will do it or not is of another matter.
I don't enjoy needles, but this is the lesser of 2 evils. Just a 2 year study and then you get on the real pill after, regardless.
Ask me any other questions if you have.
