Botox Ingredients and Composition

Each vial of Botox Purified Neurotoxin Complex contains 100 units (U) of Clostridium botulinum toxin type A, 0.5 milligrams of albumin (human), and 0.9 milligrams of sodium chloride in a sterile, vacuum-dried form without a preservative. One unit (U) corresponds to the calculated median lethal intraperitoneal dose (LD/50) in mice of the reconstituted Botox injected.

This product contains albumin, a derivative of human blood. Based on effective donor screening and product manufacturing processes, it carries an extremely remote risk for transmission of viral diseases. A theoretical risk for transmission of Creutzfeldt-Jakob disease (CJD) also is considered extremely remote. No cases of transmission of viral diseases or CJD have ever been identified for albumin.

When receiving education it may also be helpful to know what other products contain albumin. For example. Type Egg Composition on the followed link.
