Botulinum toxin injection is an injection procedure used to decrease spasticity in muscles. It can also help to prevent headaches, and it can be used to treat chronic migraines. Typically, the effect of the treatment lasts for several months.
Botulinum toxin can be administered in a number of different locations, depending on the location and the muscle group being treated. A typical procedure involves four or five sites, often involving a large muscle group.
After the injection, a numbing agent such as EMLA cream is applied to the site. The area is then chilled with coolant spray. This allows the patient to remain comfortable during the procedure.
Botulinum toxin injection is generally well tolerated. However, a few complications are possible, including bruising, swelling, or a loss of sensation. If these symptoms occur, they should be taken seriously.
Botox for Gummy Smile: A Solution
Patients should not have botulinum toxin injected in the neck, eye, or mouth areas. Some patients may experience nausea or vomiting. Fortunately, these problems are relatively rare. In the event of any serious complications, call 911 or an ambulance.
Botulinum toxin is a protein produced by Clostridium botulinum. When injected, it blocks the release of acetylcholine, the principal neurotransmitter at the neuromuscular junction. By blocking the release of acetylcholine, Botox helps to prevent muscles from contracting.
Although the use of Botox to treat chronic migraine is effective, it is not a permanent solution. In fact, some people may require more than one treatment to get the full benefit of the drug.
