Botulinum Toxin Injections

So now that we know how the toxin works, and how it can be used, it is crucial to know how it is delivered to the required muscles. Botulinum toxin is injected into affected muscles or glands using a 30-gauge 1-inch needle. Doses are created specifically for individual patients, and those doses depend on the mass of muscle being treated, therefore meaning that the larger the muscle mass, the higher the dose required. However, lower doses may be required in patients who have pre-existing weakness and in females. Toxin injections are given through hollow Teflon coated needles directly into muscles. In treating delicate conditions such as strabismus, which is a delicate area, the injections are guided by electromyography. [3]
