Cervical dystonia (spasmodic torticollis) is a neurological condition causing involuntary contractions of the neck muscles, leading to abnormal head postures, pain, and significant functional impairment. At Modal Pain Management, we use the three botulinum toxin type A products that carry an FDA indication for cervical dystonia — Botox™, Dysport™, and Daxxify™ — to reduce muscle spasm, correct head position, and relieve pain. Chronic migraine is a separate indication with a different mechanism: only Botox (onabotulinumtoxinA) is FDA-approved for it, and it works on sensory nerve endings rather than muscle. That treatment is covered on our headache and migraine injections page and in the Botox for chronic migraine guide.
Understanding Cervical Dystonia
Cervical dystonia causes the neck muscles to contract involuntarily, pulling the head into abnormal positions. The head may turn to one side (torticollis), tilt forward (anterocollis), tilt backward (retrocollis), or tilt sideways (laterocollis). How the condition is recognized, diagnosed, and why it goes years without a name is covered on the cervical dystonia condition page; this page covers the injections themselves. These involuntary movements often cause significant neck pain, muscle stiffness, and difficulty with daily activities such as driving, working, and social interaction.
The Three Products Approved for Cervical Dystonia
In cervical dystonia, all three products work the same way: they block the release of acetylcholine at the junction between nerve and muscle, so the overactive muscles contract less. Small, precise injections are placed into the overactive neck muscles identified during your evaluation, relaxing the targeted muscles, reducing spasms, and allowing the head to return to a more natural position.
Botox™ (onabotulinumtoxinA)
The most widely used and studied botulinum toxin for cervical dystonia, with decades of clinical evidence behind it. Effects typically begin within 1-2 weeks and last about three months, with treatments repeated every 12 weeks.
Dysport™ (abobotulinumtoxinA)
An FDA-approved alternative that uses a different formulation of botulinum toxin type A. Dysport™ may spread slightly more from the injection site, which can be advantageous for treating larger muscle groups involved in cervical dystonia. Some patients who do not respond optimally to one formulation may benefit from switching to another.
Daxxify™ (daxibotulinumtoxinA-lanm)
The newest botulinum toxin approved for cervical dystonia, Daxxify™ is the first formulation to use a peptide stabilizer instead of human serum albumin. In the ASPEN-1 phase 3 trial, its median duration of effect was 24 weeks at 125 units and 20 weeks at 250 units, longer than the roughly 12 weeks typical of Botox and Dysport, which can mean fewer sessions per year [1].
Treatment Protocol
- Initial Evaluation: Thorough assessment of muscle involvement, head posture patterns, and pain distribution to create a personalized injection plan
- Injection Procedure: Targeted injections administered in-office, typically taking 15-30 minutes. EMG or ultrasound guidance may be used for precise muscle targeting
- Formulation Selection: Dr. Movshis will recommend the most appropriate formulation based on your muscle involvement pattern, treatment history, and response
- Onset of Relief: Effects typically begin within 1-2 weeks, with peak improvement at 4-6 weeks
- Duration: Results generally last about three months with Botox™ or Dysport™ and 20–24 weeks with Daxxify™, with treatments repeated on a regular schedule
- Ongoing Optimization: Injection patterns, doses, and formulation selection are refined over successive treatments based on your response
Benefits of Botulinum Toxin Therapy for Cervical Dystonia
- Reduces involuntary neck muscle contractions and spasms
- Improves head and neck positioning
- Provides significant pain relief
- Restores range of motion and daily function
- Minimally invasive with minimal downtime
- Three formulations approved for cervical dystonia (Botox™, Dysport™, Daxxify™) allow the product to be matched to the patient
- Reduces dependence on oral medications that may cause sedation or other side effects
What to Expect During Treatment
Before Your Appointment
Treatment starts with careful preparation, for safety and for the best result. During your initial consultation, Dr. Movshis and our team will review your complete medical history, including any neurological conditions, muscle disorders, or previous allergic reactions. We’ll also discuss any medications or supplements you’re taking, as certain blood-thinning agents and over-the-counter products can increase bruising at injection sites. We typically recommend avoiding aspirin, ibuprofen, and vitamin E supplements for three to five days before your appointment. You’ll have a thorough neurological examination to identify which specific neck muscles are most involved in your condition and to establish baseline measurements of your head positioning and range of motion. This detailed assessment allows Dr. Movshis to create a personalized injection plan tailored to your unique muscle involvement pattern and pain profile.
During the Injection Procedure
The botulinum toxin injection procedure is performed in our comfortable in-office treatment suite and typically takes between 15 and 30 minutes from start to finish. You’ll remain awake and alert throughout the procedure, as your feedback helps guide precise muscle targeting. Dr. Movshis may use EMG (electromyography) or ultrasound guidance to locate the overactive muscles with exceptional accuracy, ensuring that the medication reaches the correct muscle groups while sparing nearby structures. The injections themselves are administered with very fine needles and cause minimal discomfort, comparable to a small pinprick. Many patients are surprised by how quickly the procedure is over and how tolerable it is. Most people require no sedation or anesthesia, though numbing cream can be applied to the skin beforehand if desired. You’ll be able to return to work or other activities immediately after treatment.
Recovery and Aftercare
The recovery process after botulinum toxin injection therapy is remarkably straightforward. Most patients experience minimal to no downtime and can resume their normal daily activities, including work, exercise, and driving, the same day. Some mild soreness or small red marks at the injection sites are common and typically fade within a few hours to one day. You may apply ice to the injection sites for the first 24 hours if desired to minimize any bruising or swelling. We recommend avoiding strenuous exercise, vigorous massaging of the treated area, and intense heat exposure (such as saunas or hot baths) for at least 24 to 48 hours following your treatment. These precautions help the medication remain localized to the targeted muscles.
You’ll begin to notice gradual improvement over the first one to two weeks as the botulinum toxin begins to block the nerve signals responsible for involuntary muscle contractions. The muscle relaxation gradually builds over time, reaching peak effectiveness at approximately four to six weeks after your injection. Some patients experience maximum benefit by week three, while others notice continued improvement through week eight. During this initial period, you may find that your neck posture gradually normalizes, your range of motion improves, and your pain decreases significantly. Keep a log of your symptoms and improvements to share with Dr. Movshis at your follow-up appointment, as this information helps refine your treatment plan for subsequent sessions.
Combined Care
We often combine botulinum toxin injections with complementary therapies for optimal results, including physical therapy to strengthen opposing muscles and improve range of motion, as well as trigger point injections and nerve blocks for additional pain relief when needed.
Savings Programs
The Botox™ Savings Program and Dysport™ patient assistance programs offer eligible patients rebates on out-of-pocket costs for cervical dystonia treatment. Most insurance plans cover botulinum toxin therapy for cervical dystonia as a medically necessary treatment, and our team can help verify your benefits and identify available savings programs before starting therapy.
