Is Botox or Juvaderm safe with Hashimoto?

 You should check with your Thyroid doctor but Botox or Juvederm as cosmetic procedures should not be a problem if the Hashimoto's is under control.

Are you looking to treat the Hashimoto with Botox? Like you have muscle pain in the neck and you want to use the Botox in this area? Or are you looking to have a cosmetic procedure in the glabella/forehead area and want to receive injections there? These are different cases and types of injections, so it's important to state the purpose of your treatment. What I would recommend is that you see the physician who treats your Hashimoto and ask him/her if you can receive Botox or fillers. While I am not aware of specific cases where Cosmetic Botox and Hashimoto have been reported, what your doctor prefers you do and don't do for your specific case will be important and any doctor who is willing to treat you with Botox or fillers, should be consulting with this physician anyway.
