Before worrying how to pay for Copaxone, maybe it is worth your time to read the following thread reposted recently by ttt1 and decide if the possible benefit of this drug justifies the cost:
Many of us choose not to use any of the disease-modifying-drugs (DMDs) because we have tried some (Personally, I have tried Betaseron, Avonex, and Copaxone.) and found no benefit, only intolerable side effects.
Many have found a greater benefit from diet and exercise -- things we can do without a prescription (or needle!). In the end, we make individual choices based on individual situations.
