How do CGRP inhibitors help treat migraine in an adult?

Hello,

Welcome to icliniq.com.

I read your query and can understand your concern.

So, having 8 migraine episodes per month with features like nausea, light sensitivity, and one-sided pain qualifies you for preventive migraine therapy, especially since acute medications like Sumatriptan and Naproxen are not consistently effective. It is good that your MRI (magnetic resonance imaging) was normal; it rules out secondary causes.

CGRP (calcitonin gene-related peptide) inhibitors (like Erenumab, Fremanezumab, or Galcanezumab) are newer, targeted preventive options that block the calcitonin gene-related peptide pathway, which is a key driver in migraine attacks.

Compared to older preventives like Propranolol, Topiramate, or Amitriptyline, CGRP inhibitors tend to have fewer systemic side effects (for example, no sedation, weight gain, or cognitive dulling seen with Topiramate).

You can opt for monthly or quarterly dosing via injection, which is convenient because they have good tolerability, though constipation and injection site reactions can occur.

Older options like Propranolol (a beta blocker), Topiramate (an anticonvulsant), and Amitriptyline (a tricyclic antidepressant) are still widely used and effective for many people, especially if there are other comorbidities like anxiety, insomnia, or hypertension.

If you prefer to avoid daily pills or have struggled with side effects, CGRP inhibitors are a good option for you.

You are right to be concerned about medication overuse headache (MOH). This can happen if acute medications are used more than 10 to 15 days per month, depending on the drug. To prevent MOH, I suggest the following -

1. Use acute treatments no more than two to three days per week.

2. Start a preventive medication to reduce the overall frequency.

3. Keep a headache diary to track triggers, patterns, and medication use.

4. Hormonal fluctuations, especially estrogen drops around menstruation, are a common migraine trigger in women, and managing hormonal patterns will help.

5. Food triggers like aged cheese, chocolate, red wine, caffeine, and processed meats can also play a role, though this varies individually.

There is growing support for certain supplements as adjunctive prevention. Some of them are -

1. Magnesium (400 to 600 mg daily), especially if low dietary intake or signs of deficiency.

2. Riboflavin (vitamin B2, 400 mg daily).

3. Coenzyme Q10 (100 to 300 mg daily).

These are generally safe and offer modest benefit, particularly for those preferring non-pharmaceutical approaches.

Lifestyle changes can make a real difference, like -

1. Regular sleep (avoid oversleeping and undersleeping).

2. Consistent meals (skipping meals is a trigger).

3. Hydration.

4. Daily exercise (even 30 minutes of walking).

5. Stress management techniques like yoga, meditation, or CBT (cognitive behavioral therapy).

I hope this helps.

Thank you and take care.

Regards.
