title: A new facial expression to botox!
abstract: Botulinum toxin (Botox) injection into the lower esophageal sphincter (LES) has been used for the treatment of achlasia cardia since the 1990s. Currently it is indicated for patients who are not candidates for definitive therapy like Heller's myotomy or pneumatic dilation and in those who have recurrence of symptoms after definitive treatments. We present a case of severe anaphylaxix due to Botox. The purpose of this case is to highlight one of the under-reported adverse effects of Botox. Anaphylactic reactions to Botox are very rare with only one other case being reported and have not been emphasized enough to be widely known in clinical practice.
