Does effectiveness of Botox diminishes over time?

I have been having Botox for my chronic migraine headaches for the past six years. The last few times I haven't been getting as good results and my headaches have been worse. I have pain 24-7. In the past the Botox helps the severity some, but not lately. Does anyone know if the effectiveness of Botox diminishes over time? Thanks!

  1. HI dwanamaker,

    Thank you for your question. I'm so sorry you are experiencing pain again. Migraine prevention medication may lose it's effectiveness over time and I would think the same applies to Botox, I'm sorry to say.

    Have you discussed this with your doctor? Of course that would be the first step, but I understand how frustrating it is to have a medication (s) work for so long and then stop. However, try not to lost hope, there are over 100 medications that can be used to treat migraine disease! Here is that information;

    I hope this helps
