I have suffered from migraines since I was 10 years old. I have been on many, many different medication‘s. The only one that works is a drug called Ergotamine Tart/Caffine suppositories, also known as Migergot 100 mg-2 mg suppositories or Cafergot. For some reason Ergotamine The ingredient needed to make the suppository Is in short supply. I have mine compounded at a local pharmacy. They cannot find a drug company that has it in stock. If anyone can help me find a reason for this I would appreciate your input and advice on this. to buy it from a drug company not a compounding pharmacy for 10 suppositories the price is almost $2,000. I have no idea why a compounding pharmacy will charge me $150 for 40 of them. I’d like to know the reason for the cost difference.
