It prevents specific neurotransmitters from reaching the affected muscles, preventing spasms. Botulinum toxin is administered by injection. One dose usually lasts about 3 months. There may be some initial (temporary) pain at the injection site. [medicalnewstoday.com]

Therefore, to prevent these and other complications, prompt and appropriate treatment of OMD is important. [dx.doi.org]
