I would avoid any injection treatment into an area that is infected. Further, cosmetic treatments should be avoided when someone has any infection in or on the body. I wish you the best, Dr. Emer.
Although Botox is safe and effective to use while on antibiotics, it should not be given with an active infection anywhere near the injection site. The inflammation and swelling could lead to migration of the Botox into other parts of the face, or the infection could be spread by the needle as it is being used.
