Dysport® is an acetylcholine release inhibitor and a neuromuscular blocking agent indicated for the treatment of adults with cervical dystonia to reduce the severity of abnormal head position and neck pain in both toxin-naive and previously treated patients.
What are the ingredients in DYSPORT®?
Active ingredient: (botulinum toxin Type A)
Inactive ingredients: human albumin, and lactose. DYSPORT® may contain cow's milk protein.
What is DYSPORT®?
DYSPORT™ is a prescription medicine that is injected into muscles and used:
- to treat the abnormal head position and neck pain that happens with cervical dystonia (CD) in adults
- to improve the look of moderate to severe frown lines between the eyebrows (glabellar lines) in adults younger than 65 years of age for a short period of time (temporary)
CD is caused by muscle spasms in the neck. These spasms cause abnormal position of the head and often neck pain. After DYSPORT™ is injected into muscles, those muscles are weakened for up to 12 to 16 weeks or longer. This may help lessen your symptoms.
Frown lines (wrinkles) happen because the muscles that control facial expression are used often (muscle tightening over and over). After DYSPORT™ is injected into the muscles that control facial expression, the medicine stops the tightening of these muscles for up to 4 months.
It is not known whether DYSPORT® is safe or effective in children under 18 years of age.
It is not known whether DYSPORT® is safe or effective for the treatment of other types of muscle spasms. It is not known whether DYSPORT™ is safe or effective for the treatment of other wrinkles.
Important Safety Information
Distant Spread of Toxin Effect: Postmarketing reports indicate that the effects of Dysport and all botulinum toxin products may spread from the area of injection to produce symptoms consistent with botulinum toxin effects. These may include asthenia, generalized muscle weakness, diplopia, blurred vision, ptosis, dysphagia, dysphonia, dysarthria, urinary incontinence, and breathing difficulties. These symptoms have been reported hours to weeks after injection. Swallowing and breathing difficulties can be life threatening, and there have been reports of death. The risk of symptoms is probably greatest in children treated for spasticity, but symptoms can also occur in adults treated for spasticity and other conditions, particularly in those patients who have underlying conditions that would predispose them to these symptoms. In unapproved uses, including spasticity in children and adults, and in approved indications, cases of spread of effect have been reported at doses comparable to those used to treat cervical dystonia and at lower doses.
Dysport is contraindicated in patients with hypersensitivity to any botulinum toxin product or its excipients, including human albumin, lactose, and cow's milk protein, or who have an infection at the proposed injection site.
The potency Units of Dysport are not interchangeable with other preparations of botulinum toxin products and, therefore, Units of biological activity of Dysport cannot be compared to or converted into Units of any other botulinum toxin products. Recommended dose and frequency of administration should not be exceeded.
Immediate medical attention may be required in cases of respiratory, speech, or swallowing difficulties. Dysphagia may persist for several weeks, and require use of a feeding tube to maintain adequate nutrition and hydration. Aspiration may result from severe dysphagia and is a particular risk when treating patients in whom swallowing or respiratory function is already compromised. Concomitant neuromuscular disorder may exacerbate clinical effects of treatment.
Individuals with peripheral motor neuropathic diseases, amyotrophic lateral sclerosis, or neuromuscular junction disorders should be monitored particularly closely when given botulinum toxin. Patients with neuromuscular disorders may be at increased risk of clinically significant effects, including severe dysphagia and respiratory compromise from typical doses of Dysport.
Dysport contains human albumin. Based on effective donor screening and product manufacturing processes, Dysport carries an extremely remote risk for transmission of viral diseases. A theoretical risk for transmission of Creutzfeldt-Jakob disease (CJD) also is considered extremely remote. No cases of transmission of viral diseases or CJD have ever been identified for albumin.
The possibility of an immune reaction when injected intradermally is unknown. The safety of Dysport for the treatment of hyperhidrosis has not been established.
Patients receiving concomitant treatment of Dysport and aminoglycosides or other agents interfering with neuromuscular transmission (e.g., curare-like agents), or muscle relaxants, should be observed closely because the effect of botulinum toxin may be potentiated. Use of anticholinergic drugs may potentiate systemic anticholinergic effects. The effect of administering different botulinum neurotoxins during the course of treatment with Dysport is unknown.
