Botulinum Toxin Injections

Visit our Specialty Center

Botulinum toxin injection is a treatment that uses a small, carefully controlled dose of a potent neurotoxin to calm the specific muscles responsible for abnormal movements, spasms, or excessive drooling. It’s most commonly used to treat movement disorders such as myoclonus, hemifacial spasm, spasticity, tremor, blepharospasm, cervical dystonia, spasmodic torticollis, and dystonia of the leg and foot, with most patients noticing benefit within 3 to 10 days and relief lasting several months.

The treatment involves injecting a small dose of Clostridium botulinum — the neurotoxin the treatment is derived from — directly into the muscle responsible for the abnormal movement or spasm. By temporarily blocking the nerve signals that trigger these contractions, the injection allows the affected muscle to relax. Injections are performed in an office setting, and any discomfort is generally temporary and minor. Because the effect is temporary, most patients return periodically for repeat treatment to maintain symptom relief.
