Patient's Query
Hi doctor,
I am a 33-year-old female with migraines that strike right before my period. Triptans help only halfway. My neurologist suggested a monthly CGRP injection, but I am worried about long-term effects on hormones or future pregnancy plans. Are these shots safe for women whose migraines are clearly tied to estrogen swings? Do they interact with birth-control pills or cause weight changes?
Please guide.
Thank you.
Hi,
Welcome to icliniq.com.
I read your query and understand your concerns.
Menstrual migraines like yours are often triggered by the natural drop in estrogen levels that occurs right before a period, and while triptans can help, they do not always provide full relief for hormonally driven migraines. CGRP (calcitonin gene-related peptide) inhibitors such as Erenumab, Fremanezumab, or Galcanezumab are a newer class of preventive treatment that have been shown to significantly reduce the frequency and severity of migraines, including menstrual ones.
These injections do not directly affect estrogen levels or hormonal balance, and current research suggests they are safe for women with hormone-related migraines. They do not interfere with birth control pills or other hormonal contraceptives, and most women report no impact on their menstrual cycle.
In terms of weight, CGRP inhibitors are generally weight-neutral, though a small number of users have reported either mild weight loss or gain, but this has not been consistent or clearly linked to the medication.
If you are planning a pregnancy in the near future, it is important to know that while these drugs are not currently recommended during pregnancy due to limited safety data, they can be discontinued if you start trying to conceive. Overall, CGRP inhibitors are considered a safe and effective option for women with estrogen-sensitive migraines, especially when other treatments have not provided full relief.
I hope this answers your query.
Let me know if I need to assist you further.
Thank you.
