Botox

(BOTOX MOLECULES pictured above and below)

      Botox injections are used primarily to reduce the appearance of facial wrinkles. Botox injections use a toxin called onobotulinumtoxinA to temporarily prevent a muscle from moving. This toxin is produced by the bacteria that causes botulism, a type of food poisoning.
      Botox was the first drug to use botulinum toxin. Other products now include drugs like abobotulinumtoxinA (Dysport) and incobotulinumtoxinA (Xeomin).  All 3 drugs are FDA approved, but vary in molecular weight, protein content, and excipient (vehicle used to deliver the drug)

Possible side effects and complications include:
      Pain, swelling or bruising at the injection site
      Headache or flu-like symptoms
      Droopy eyelid (ptosis) or cockeyed eyebrows
      Crooked smile or drooling

You should NOT get Botox injections if you have a history of:
      allergies to eggs, egg products, or albumin
      significant autoimmune or neurological diseases
      pregnancy
