That is a question for the Pharma companies, supply demand and greed.
All I can suggest and to talk to your doc and see what else can be perscribed.
I understand your frustration, I have been there twice. Try not to get anxious, stay as calm as possible, or you migraines will become worse.
Peace and strength
