No, weight loss or weight gain isn’t a side effect of Aimovig. Weight changes weren’t reported in clinical studies of people using the drug.
A different medication called topiramate (Topamax), which is also used to prevent migraine headaches, can cause weight loss.
Keep in mind that you may lose your appetite when you have migraine headaches, so that could cause you to lose weight.
On the other hand, there is a connection between weight and migraine episodes. Obesity may lead to an increase in the number or severity of migraine headaches, according to a studyTrusted Source.
If you have concerns about losing or gaining weight during your Aimovig treatment, talk with your doctor.
