Botox (onabotulinum toxin type A) injections use a medicinal toxin to temporarily prevent a muscle from moving. Botox injections block certain chemical signals from nerves, mostly signals that cause muscles to contract. Botox injections are also used to treat conditions that affect how the body functions. Some examples include:
- Cervical dystonia. In this painful condition, your neck muscles contract involuntarily, causing your head to twist or turn into an uncomfortable position (OHIP-covered indication).
- Muscle contractures. Some neurological conditions, such as cerebral palsy, can cause your limbs to pull in toward your center. In some cases, these contracted muscles can be relaxed with Botox injections (OHIP-covered indication).
If you experience Chronic migraines more than 15 days a month, Botox injections may help reduce headache frequency and severity (covered by most extended benefit plans).
