How close in relationship is tecfidera & copaxone (glatiramer)?

VERY DIFFERENT: Entirely different chemical classes, with distinct different mechanisms of action, and outcome data. Both seem safe, Copaxone (glatiramer) tho is injected daily, causes lipoatrophy, hypertension, and injection reactions. Tecfidera may be tough to tolerate due to flushing, nausea, diarrhea, stomach pain. Copaxone (glatiramer) relapse reduction is 29%, but tecfidera, drops 44-52%, oral twice daily, no needles. Talk to doc.
