Many TEC users feel this drug needs to be increased more slowly than it is now. I made it through without the usual side effects until about day 19 when I got a headache/head pressure/ringing in the ears/dizzy that just got worse and worse until I gave it up on day 25. Doc called it an adverse reaction.
I noticed on some sites that 60% of TEC users sail through it but the other 40% really have some issues. I was really hoping to be in that 60%.
You can't take a lesser dose of this drug because it is a filled capsule. Perhaps you can ask your doc about a different dosing schedule, but I think only the MS specialists are really on top of this.
Sorry that you are in the 40%

If you get the side effects pretty bad, the drug is a drag!!!!
