Happy new year ! Hope you're doing OK so far. 😀 I can totally relate to being miserably cold this time of year, and actually was just gifted my first electric blanket. I am in HEAVEN. So, solidarity with you on that. Haha
Jake gave you some good info to start with. Did you have Raynaud's prior to starting Ajovy and the zavzepret? Raynaud's is specific to small blood vessels like the fingers and toes, not a full-body cold. But migraine itself can make it hard for people to regulate their body temperature.
One thing I do want to note is that the literature for Zavzepret specifically lists the development of Raynaud's as a potential side effect. It also says you should let your doctor know if you have Raynaud's prior to starting. Did the doctor ask you any questions about it when you first got the prescription? Either way, it's a good idea to let them know you're freezing just so they can be aware.
Keep in mind that it's always up to you what to do next -- sometimes the side effects are too much, and sometimes a person might feel it's worth it to put up with side effects for the relief they get.
Definitely keep us posted. Medication can definitely do some interesting things! Hang in there and stay warm. -Melissa, team member
