Before Using
In deciding to use a medicine, the risks of taking the medicine must be weighed against the good it will do. This is a decision you and your doctor will make. For this medicine, the following should be considered:
Allergies
Tell your doctor if you have ever had any unusual or allergic reaction to this medicine or any other medicines. Also tell your health care professional if you have any other types of allergies, such as to foods, dyes, preservatives, or animals. For non-prescription products, read the label or package ingredients carefully.
Pediatric
Appropriate studies have not been performed on the relationship of age to the effects of abobotulinumtoxinA in children with cervical dystonia, and in children younger than 2 years of age with lower limb spasms or upper limb spasms, including spasms caused by cerebral palsy. Safety and efficacy have not been established.
Use of abobotulinumtoxinA to treat glabellar lines is not recommended in children.
Geriatric
Appropriate studies performed to date have not demonstrated geriatric-specific problems that would limit the usefulness of abobotulinumtoxinA in the elderly. However, elderly patients are more sensitive to the effects of this medicine than younger adults and are more likely to have falls, weakness, or side effects related to the eyes, which may require caution in patients receiving abobotulinumtoxinA for lower limb spasticity and glabellar lines.
