Talk to the prescribing doctor about this. They will want to rule out an allergic reaction before continuing the medication, I would think.
ADDitude’s medication summary for Straterra reads:
“Contact your doctor immediately if you or your child experiences these signs of liver problems: itching, right upper belly pain, dark urine, yellow skin or eyes, or inexplicable flu-like symptoms.”
