Have your doctor prescribe your normal dose, which hopefully your insurance covers, and then take those standard-dose pills to the compounding pharmacy, and they will charge you to make custom doses out of them.
The total cost
for the custom Lyrica
capsules was about $200, and for the Savella it was like $120. If your compounding pharmacy requires a note from your doctor, have your doctor write one up.
I suffered from fibromyalgia pain for six years. Lyrica and Savella were awesome for me.
