What is DYSPORT™ (abobotulinumtoxin a injection) ?

DYSPORT™ (abobotulinumtoxin a injection) 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™ (abobotulinumtoxin a injection) 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™ (abobotulinumtoxin a injection) is injected into the muscles that control facial expression, the medicine stops the tightening of these muscles for up to 4 months.
