It is not entirely clear how Aubagio works to treat multiple sclerosis. What is known is that the drug blocks an enzyme in the body that is needed to make molecules known as pyrimidines. Lymphocytes (a white blood cell type involved in inflammation and active in MS) need pyrimidines to divide and reproduce. By preventing the body from making pyrimidines, Aubagio reduces the number of lymphocytes in the body, which may be the reason it works to prevent MS relapses.
This drug has not been approved for use in children, as it has not been adequately studied in this age group (usually defined as individuals younger than 18 years old). Talk to your child's healthcare provider about the risks and benefits of using Aubagio in your child.
Aubagio can be used in older adults. However, clinical studies of the drug did not include people over the age of 65 years old. Therefore, it is unknown whether older adults will respond to or tolerate the medication any differently than other age groups. For this reason, this drug should probably be used cautiously in older adults.
On occasion, your healthcare provider may recommend this medicine for treating something other than multiple sclerosis. This is called an "off-label" use. At this time, there are no well-accepted off-label uses for Aubagio.
