Can CGRP inhibitors help manage my chronic migraines at 38?

Question

Hello doctor,

I am 38 years old and suffer from chronic migraines, experiencing approximately 22 headache days per month. My neurologist prescribed Topiramate 100 mg twice daily for prevention, but the cognitive side effects have been unbearable. I feel like I am in a constant mental fog, and I have lost 18 pounds due to appetite suppression.

For acute treatment, I take Sumatriptan 100 mg, but I am now experiencing medication overuse headaches from using it more than 15 times per month. My most recent MRI was normal, but the headaches remain severe, often nine out of 10 in intensity, accompanied by nausea, vomiting, and sensitivity to light. I had to take leave from work because I was missing three to four days each week.

My magnesium level is low at 1.6 mg/dL, and my vitamin D is deficient at 18 ng/mL, despite ongoing supplementation. I have tried eliminating common dietary triggers like chocolate, wine, and aged cheeses, but it has not made a difference.

Should I consider CGRP inhibitors like Aimovig or Emgality? What about Botox injections? The financial burden is overwhelming. My teenage son becomes frightened during my attacks because I become irritable and need complete darkness.

I am desperate for a solution that does not involve daily medications with intolerable side effects.

Please help.

Hello,

Welcome to icliniq.com.

I understand your concern regarding your symptoms.

Given the severity and frequency of your migraines, your condition clearly meets the criteria for chronic migraine. It is entirely understandable that both the symptoms and the burden of treatment are profoundly affecting your quality of life.

Since Topiramate is causing significant cognitive side effects and weight loss, it may be appropriate to taper off the medication under medical supervision. CGRP (calcitonin gene-related peptide) monoclonal antibodies, such as Aimovig (Erenumab), Emgality (Galcanezumab), and Ajovy (Fremanezumab), are FDA (Food and Drug Administration)-approved for the prevention of chronic migraine and generally have fewer systemic side effects. These treatments are administered monthly and are not associated with the mental fog or appetite suppression commonly seen with Topiramate, making them a strong next option.

Clinical evidence also supports Botox (OnabotulinumtoxinA) injections every 12 weeks for chronic migraine, particularly in individuals with 15 or more headache days per month. Many patients report meaningful relief with a relatively low side-effect profile. In more refractory cases, a combination of Botox and a CGRP inhibitor is sometimes used to achieve better control.

In terms of acute treatment, using Sumatriptan more than 10 days per month can contribute to medication-overuse headaches. Reducing reliance on abortive medications by improving your preventive regimen is key to breaking this cycle.

Your low magnesium (1.6 mg/dL) and vitamin D (18 ng/mL) levels may be contributing factors. Optimizing these under your physician’s guidance could be beneficial. Magnesium glycinate is often better tolerated and more effective than other forms.

Regarding the emotional and financial strain, it is worth noting that many manufacturers of CGRP inhibitors and Botox offer savings programs or patient assistance foundations. Your healthcare provider or a case manager can help you explore these options. Consult your specialist doctor, discuss with them, and take the medicines with their consent.

Given the significant impact this condition is having on your daily functioning and family life, it is absolutely worth revisiting your treatment plan as soon as possible. Better-tolerated and more effective options are available that could help restore your quality of life without the debilitating side effects you are currently experiencing.

I hope this helps you.
