Can anyone tell me the difference between Copaxone 7 day vs Copaxone 3 day other than the obvious in amount of days you take it? Has anyone had problems with Copaxone 3 day? I tolerate 7 day just fine. However, a past doctor wanted me to switch to 3 day Copaxone. Going to see what the new neuro recommends first but was curious to know more about Copaxone 3 day. Grateful for any info.
