Botox for Movement Disorders

What is Botox for movement disorders?

Botox, or botulinum toxin, is a therapeutic drug made from the bacterium Colistridium botulinum. It is often used to temporarily smooth facial wrinkles, but it can also be an effective treatment for some medical conditions—including movement disorders.

When injected directly into a muscle, Botox temporarily blocks the release of the acetylcholine—the neurotransmitter that tells the muscle to contract. This allows the muscle to relax.

Depending on the number of injections needed, the entire procedure takes about 15-30 minutes. Results typically appear in three to seven days, and the effect usually lasts three to four months.

Am I a good candidate for Botox for movement disorders?

You may be a good candidate for Botox injections if you are at least 18 years old and have been diagnosed with one of the conditions above. 

Although Botox is a toxin, it is generally safe and effective when used in correct dosages by trained providers. The most common side effect is temporary muscle weakness near injection sites. You may also experience pain, bruising, or bleeding at the injection sites. Rarely, it can cause generalized weakness or flu-like symptoms.

You should not take Botox if you:

  • Are allergic to any of its ingredients or have had an allergic reaction to another Botox product
  • Are pregnant
  • Have a neuromuscular condition (i.e. amyotrophic lateral sclerosis (ALS) or myasthenia gravis)
  • Have Lambert-Eaton syndrome

Tell your doctor about all of your medical conditions and medications during your evaluation for Botox therapy.
