Can Botox Injected into the Forehead Go Through and Get into the Bloodstream?

What anything is possible, it is not probable.  Most likely the needle irritated a sensory nerve in your forehead which may give you temporary discomfort.  If your symptoms do not improve, you should see the advice of your doctor as it may just be coincidental and have nothing to do with the Botox at all.

 

Good Luck.

The FDA recently required a much stronger warning regarding the use of BOTOX and other BoNT products.  Cosmetic BOTOX is very safe.  However, systemic side effects do occur.  Generally, for cosmetic treatments, they are short lived, like on the order of a week.  Headache and flu like symptoms are part of this syndrome.  It is not clear that the treatment has to actually be injected into a vessel for you to experience these symptoms.  Generally they are more bothersome than serious.  You will have to personally decide if the limited side effects are worrisome enough for you to continue receiving BOTOX treatment or to swear them off.  Personally, I find BOTOX so helpful that I am willing to put up with some minor short term side effects.
