Neurotoxin (Botox, Dysport, Xeomin)
Neurotoxins, also known by brand names Botox, Dysport, and Xeomin, are injectable medications that work by temporarily relaxing muscles. They are purified proteins derived from the bacterium Clostridium botulinum. While this bacteria causes a serious illness called botulism, when the toxin is purified and injected in tiny amounts into specific muscles, it can be a safe and effective treatment for a variety of conditions.
How do Neurotoxins work?
Neurotoxins work by blocking the release of acetylcholine, a chemical messenger that signals muscles to contract. When acetylcholine is released at the neuromuscular junction (the place where nerve cells meet muscle cells), it causes the muscle to contract. By blocking the release of acetylcholine, neurotoxins prevent the muscles from contracting, which can relax wrinkles, reduce muscle spasms, and block pain signals.
Are Neurotoxins safe?
Neurotoxins are generally safe when used as directed by a qualified healthcare professional. However, there are some potential side effects, such as:
- Bruising or swelling at the injection site
- Headache
- Muscle weakness
- Drooping eyelids (ptosis)
In rare cases, more serious side effects can occur, such as difficulty swallowing or breathing. It is important to discuss the risks and benefits of neurotoxin treatment with your provider.
Who should not use Neurotoxins?
Neurotoxins are not appropriate for everyone. People who should not use neurotoxins include those who are pregnant or breastfeeding, have a neuromuscular disease, or are allergic to any of the ingredients in the injection.
