Dear Colleague,

Welcome to the International Neurotoxin Association (INA). We are a not-for-profit, international scientific society dedicated to advancing scientific research, supporting education, and fostering understanding about botulinum and other neurotoxins.

The INA provides a forum for the exchange of information and ideas among scientists, clinicians, and other allied health professionals about the science and therapeutic use of neurotoxins.

We have begun planning for TOXINS 2026. Please check this website and the INA social media pages on Facebook, Twitter, LinkedIn, and Instagram for updates on TOXINS 2026.

In addition to organizing the biennial TOXINS Conferences, the INA has now initiated the Injector Preceptorship Initiative.

This one-on-one preceptorship program is designed for injectors of all levels of experience—from novice to expert—who wish to learn and/or improve their injection skills using botulinum neurotoxin. Click on the preceptorship link to view the program and mentors.

I wish to invite you to join the INA. Our membership is open to individuals with an interest in the field and can be requested by clicking on the “Membership” tab above and completing the application form. Currently, there is no fee for membership. I look forward to welcoming you as an INA member!

Best regards,

David M. Simpson, MD
President
International Neurotoxin Association
