What is equivalent to Ajovy?

Can you explain what medication or treatment is comparable to Ajovy in terms of its function and intended purpose? Ajovy is a specific medication used to prevent migraine headaches, so I'm looking for a similar drug or alternative therapy that could potentially yield similar results. Is there a generic version of Ajovy available, or perhaps another prescription drug or over-the-counter medication that has a similar mechanism of action? Additionally, are there any non-pharmacological treatments or lifestyle changes that could serve as a viable alternative to Ajovy?
