Can CGRP inhibitors and Botox help manage severe migraine?

Question

Hello doctor,

I have been dealing with migraines for years, but recently they have become more frequent, about three to four times a week. The pain is intense, usually on one side, with nausea and sensitivity to light and sound. I have tried triptans, preventive medications, and over-the-counter drugs, but the relief does not last, and I am worried about overuse. I have read about CGRP (Calcitonin Gene-Related Peptide) inhibitors and Botox. Are they effective and safe for someone with high blood pressure? I am tired of losing days to this and want a better plan.

Please help.

Hello,

Welcome to icliniq.com.

I understand your concern.

You likely meet the criteria for chronic migraine, defined as having more than 15 headache days per month with at least eight days showing migraine features for over three months. This shifts your care from treating occasional migraines to needing a more structured, preventive approach. Newer treatments such as CGRP (calcitonin gene-related peptide) inhibitors like Erenumab, Fremanezumab, and Galcanezumab are effective in reducing migraine frequency by 50 percent or more in many patients. These are monthly injections and are generally safe for people with high blood pressure, though Erenumab may raise blood pressure in some cases, so monitoring is advised.

Another proven option is Onabotulinumtoxin A (Botox), which is FDA (Food and Drug Administration)-approved specifically for chronic migraine and administered every 12 weeks through multiple small injections around the head and neck. It usually begins to work after two to three treatment cycles and is well tolerated, even in individuals with hypertension. If you are using triptans, NSAIDs (non-steroidal anti-inflammatory drugs), or Acetaminophen more than 10 to 15 days per month, you may be experiencing medication-overuse headache, which can worsen your condition. A neurologist or headache specialist can guide you on whether CGRP inhibitors or Botox are suitable for you.

Keeping a migraine diary and considering other preventive medications like Topiramate, Propranolol, or Candesartan can also help, especially with blood pressure in mind. Supporting strategies such as good sleep, hydration, regular meals, and supplements like Magnesium and Riboflavin may provide additional benefit. Overall, both CGRP inhibitors and Botox are effective, safe options that can offer lasting relief when migraines become chronic.
