• Dysport is injected into the affected muscles.

• Your doctor may change your dose of Dysport, until you and your doctor find the best dose for you.
• Your doctor will tell you how often you will receive your dose of Dysport injections.

Indication-specific dosage and administration recommendations should be followed. Dysport should not be administered more frequently than every 12 weeks.

Symptoms of overdose after Dysport injection may include difficulty breathing, difficulty moving parts of the body, and weakness. These symptoms may not appear right away. Call your doctor or seek emergency medical attention right away if you experience any of these symptoms.

WARNING: DISTANT SPREAD OF TOXIN EFFECT
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 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 occur in adults, particularly in those patients who have underlying conditions that would predispose them to these symptoms.
