Are CGRP or Botox treatments effective for migraines?

Question

Hello doctor,

I am 41 years old, and I have been suffering from migraines for over 15 years. I get pain, nausea, and light sensitivity for 12 to 14 days a month. I am taking Topiramate and occasionally use Triptans, but it is not enough. My neurologist mentioned CGRP (calcitonin gene-related peptide) monoclonal antibodies or Botox.

Are these both used together or separately?
Which one is more effective for chronic migraines?
How long does it take to work?

Please suggest.

Thank you.

Hello,

Welcome to icliniq.com.

I have read your query and can understand your concern.

The probable cause and diagnosis are migraine. CGRP (calcitonin gene-related peptide) monoclonal antibodies (mAbs) and Botox (onabotulinumtoxinA) are effective treatments for chronic migraine, but they work through different mechanisms and have varying characteristics. CGRP mAbs are specifically designed to target CGRP (calcitonin gene-related peptide), a molecule involved in migraine, while Botox works by blocking neurotransmitter release from sensory neurons, potentially reducing pain associated with excessive muscle contractions.

While both are effective, some studies suggest that Botox may be more effective for some patients, particularly those with chronic migraine. Combination therapy with both CGRP (calcitonin gene-related peptide) mAbs and Botox may be considered for those who have not achieved sufficient relief with either treatment alone. CGRP monoclonal antibodies (mAbs) and Botox injections offer relief from migraines, but their duration of effect differs.

CGRP (calcitonin gene-related peptide) mAbs, like Erenumab, Fremanezumab, and Galcanezumab, are administered monthly or every three months for some people and can provide relief within the first month, with some experiencing improvement even after the first dose. Botox injections, on the other hand, are typically administered every twelve weeks and can take a few weeks to start relieving migraines.

I hope this answers your query.
