Botulinum toxins like Botox are neurotoxins derived of a bacterium called Clostridium botulinum.
This bacterium is found in contaminated foods and soils and is the same one behind a condition called botulism, a serious illness that causes difficulty breathing, muscle paralysis, and even death.
Getting botulinum toxin injections for medical reasons, though, can help treat conditions such as chronic migraine.
Using a very small needle, your doctor injects the neurotoxins into tiny muscles under your skin on your face, head, and neck — specifically, in your forehead, temples, and the back of your head and neck. You may also ask your doctor to target any “trigger points” where your head pain tends to be concentrated.
These neurotoxins enter pain-causing nerve endings and stop the release of chemicals that cause pain transmission. In other words, they block the chemicals that tell your brain you’re in pain.
Botulinum toxin injections that are given to prevent chronic migraine are typically administered every 12 weeks.
