Methysergide, sold under the brand names Deseril, Deserila, and Sansert is a drug that has helped many people suffering from devastating, life-destroying migraines live a regular life since 1962. For many people, this is the only thing that works, period. 

Novartis withdrew it from the U.S. market in 2014 after taking over Sandoz, and it's impossible to get it anywhere in the world since then. 

Recent research showed that it can cause fibrosis in rare cases and this is used as the reason for withdrawal, but many people have been using this drug for over 30 years with zero problems. Their life has become a living hell again.

The drug is allowed by the FDA and other health agencies around the world. No law prohibits its production.

There is no reason why people should live in pain to the point where they can't even leave their house when the cure has been out there for over 50 years!
