The positive effects of botulinum toxin injections can last up to 16 weeks, sometimes longer; although many people find that the injections need repeating before this and usually attend a clinic around every 12 weeks.
The injection effectively blocks the acetylcholine nerve transmission. This prevents the muscle from contracting and reduces pain. The results of treatment are often most effective in two to six weeks after the injection, and the effect will continue to last for up to six months.
