I just had Botox injections in my forehead and between brows 2 days ago. What should I do?

This is not a rare concern after facial Botox treatment. You can use Ibuprofen or Tylenol or whatever usual headache medications work for you at this point. Stephen Weber MD, FACSDenver Facial Plastic Surgeon

Headaches can occur after Botox or other neurotoxin injections. I have some patients that say they only get headaches when they have Botox and others and only get headaches when they have Dysport. I also have some patients that say they get headaches when they go to certain injectors. This may be partly because of the way they dilute the neurotoxin. Often putting more volume into tissue causes more stretch of the tissue, leading to headaches.   If headaches to occur, they typically don't last more than a couple days. You can also treat this was standard medication such as Tylenol or Advil aspirin ibuprofen etc.   I would only avoid things that can thin your blood if you already have an active bruise that is associated with your neurotoxin injection. If it is after 24 hours, and you are not bruised,  you're probably safe to take all of the above medications.

Sometimes a headache can develop after a BOTOX injection.  If that is the case, unfortunately all you can do is wait it out.  Treat your headache with the meds that you normally use when you get a headache.  Advil is OK if that works for you
