Are CGRP blockers safe for hormonal migraine in women?

Question

Hello doctor,

I am a 33-year-old female with migraines that come with a visual aura. I used to take triptans, but they do not help much. My neurologist mentioned a migraine injection (maybe a CGRP blocker). Is this safe for women who also have hormonal migraines? I am worried about side effects and long‑term use.

Kindly help.

Thank you.

Hello,

Welcome to icliniq.com.

I read your query and understood your concern.

Your neurologist is referring to CGRP monoclonal antibodies, which are a newer class of medications designed to prevent migraines, including those with aura and hormonal triggers. These injections target the calcitonin gene‑related peptide (CGRP) pathway, which plays a key role in migraine inflammation and pain.

They are not pain relievers like triptans. They are preventive treatments that can reduce both the frequency and severity of migraines. There are a few CGRP options approved for use, including Erenumab (Aimovig), Fremanezumab (Ajovy), Galcanezumab (Emgality), and Eptinezumab (Vyepti). These are typically administered once monthly (or quarterly, depending on the formulation) and are generally very well tolerated even with long‑term use.

Importantly, they have been shown to be safe and effective in women who experience hormonal migraines, which often occur around the menstrual cycle or with birth control or hormone shifts. Side effects are usually mild. Serious side effects are rare. The most commonly reported include the following:

Injection site reactions.
Constipation.
Mild fatigue.
Muscle pain.

Because these medications act on a very specific pathway and do not affect the heart or blood vessels like triptans do, they are considered safer in patients with aura, who are often advised to avoid estrogen‑containing birth control or vasoconstrictive drugs due to a slightly higher stroke risk. That makes CGRP blockers an especially good fit for many women in this situation. Long‑term safety data are reassuring so far, with many patients using these medications for several years without significant issues.

These treatments can be profoundly beneficial for people with frequent migraines that do not respond well to triptans or other medications. Insurance coverage and cost can be barriers. If migraines are clearly tied to the menstrual cycle, there are also options to combine CGRP therapy with hormonal stabilization strategies, such as continuous birth control or short‑term preventive triptan use during vulnerable days.

I hope that this answers your query.

Kindly follow up if you have more doubts.
