My daughter is 5 years old and has ADHD. She recently went on the drug
Concerta, then her PCP prescribed cetirizine as well for hay fever that I didn't even realize she had. On a routine cardiology check for the Concerta meds, the cardiologist discovered my daughter had PACs. The cardiologist took her off all of her meds for 10 days and did another EKG. She still had the PACs even off meds. Now my daughter is on atenolol 2 mL per day, Concerta, and cetirizine all together.
