1) longest history here in US. No unexpected side effects. (ie: PML & Tysabri)
2) Short needle vs. Avonex
3) Less site pain and reactions compared to Rebif
4) Copaxone is every day.
These were my deciding factors. My wife is a pharmacist so I also get feedback from her.....and she hears it from the patients that come to have RX's filled.
As for site rotation, I have settled on the arms, hip, legs. The stomach hurt too much. Have only ever had one site reaction and it was no big deal.....just a bruise once. Use your regular calendar and just put letters for site locations. I use LA= left arm / LH= left hip / RL= right leg....etc
Does one work better???? Who knows, they all have 30% - 35% as advertised effectiveness. Pretty crummy really.
I've been taking Betaseron for about 1 1/2 years.
USe the Autoject....makes it easier to get used to.
Dose titration is also supposed to be important when starting to avoid the bad side effects. Ask Doc about this. Seemed to work for me, I don't have any side effects ever. Sometimes just feel like I didn't have a great nights sleep the night before. Never take NSAID drugs either (no need).
