No, Botox does not contain sulfa and if your only allergy is to sulfa, it should be safe to proceed with Botox. That said, you need to review all your allergies with your provide prior to an injection.Best regards,Thomas Walker, MD, FACS
Many brands of Botox exist. They are derivatives of botulinum toxin but do not contain sulfa. The Botox is mixed and reconstituted with different substances. I recommend you advise your provider if you have any additional allergies.
