When used in a medical setting as an injectable form of sterile, purified botulinum toxin, small doses block the release of a chemical called acetylcholine by nerve cells that signal muscle contraction.

The medication takes 48 to 72 hours to take effect and can be expected to last about 3 months, though individual results vary and additional injections may be necessary to get desired results.
