How Does the Botulinum Toxin Work?
Normally, the brain sends electrical messages to the muscles so that they can contract and move. This message is transmitted to the muscle by a substance called acetylcholine. Botulinum toxin works to block the release of acetylcholine; therefore the muscle doesn't receive the message to contract.
How Are Botulinum Toxin Treatments Given?
Botulinum toxin is given as an intramuscular injection (in the muscle). Your doctor will determine the muscle(s) in need of treatment.
If the muscles to be injected are small or difficult to reach, it may be necessary to send short electric impulses, or to record electric signals from the muscles, to ensure that the appropriate muscles are receiving the injected medication.
A very fine needle is used for the injection. Some people report minor and temporary discomfort from the injection. The medication does not sting or cause irritation after it has been injected.
You can expect the appointment to last from 1 to 2 hours.
The effects of the medication begin to appear from one to two weeks after the injection. The muscles injected should then relax.
