Botulinum Toxin Injections

What is Botulinum Toxin?

Botulinum toxin naturally originates from the bacterium Clostridium botulinum. Currently, it is the most virulent biological toxin known to exist. So far the FDA has approved Botox (Botulinum toxin type A) and Myobloc (Botulinum toxin type B) for human use.

How do Botulinum Toxin Injections work?

With the help of the EMG procedure, Botulinum toxin injections are precisely injected into the dystonic muscles. The toxin obstructs the path of acetylcholines which derives from the brain. This blockade weakens the perpetual signals thus allowing the contracted muscles to relax and return to a more natural movable state. 

How long do the effects last?

Botox injections will need to reoccur every 3-4 months (depending on the dosage) by your healthcare specialist who has had experience with Botulinum toxin injections. There is a maximum limit to the total amount of Botulinum toxin that can be injected into the body in one visit.

What are some advantages of Botulinum Toxin Injections?
  • The injection is released into a concentrated area unlike oral medications which effects a wider area.

  • It is reported to aid Parkinson's Disease patients with tremor, reduction of saliva production, bladder difficulties, and constipation.

  • It is used to reduce overactive muscle activity.

Are there any side effects?

As with all medications, there may be side effects as a result of usage. Side effects are predominantly determined based on the location of the injection, but differ from person to person. The dosage amount of botulinum toxin may also result in side effects. Most side effects are mild and may include: droopy eyelids, pain, headaches, sensitivity and bruising at the injection site, weakness, etc.
