Possible Side Effects
Parents and caregivers often notice their child is irritable when they are on Acthar. Although it can be very upsetting, the irritability itself isn’t harmful to your child. Also, if irritability occurs, do not mistake it as a sign that the medication isn’t working. In addition to irritability, appetite changes and weight gain are commonly noticed with Acthar but are not considered harmful. These side effects of the medication will likely disappear after your child completes Acthar therapy.
The most common side effects of Acthar in infants include: infections, increased blood pressure, irritability and changes in behavior, changes in appetite and weight, diarrhea, and vomiting.
