My 10 year old nephew came to visit for the weekend, with a new medication that concerns me. He has taken medication for ADHD for about 6 years now, as well as sleep medication. His father sent his Vyanse medication for ADHD, but instead of the usual Mirtazapine for sleep, he sent new Hydroxyzine Pamoate with instructions to take it before bedtime for sleep. Due to situations involving Child Protective Services and Parental Custody Court Orders, there is no communication with the father. I did a short research on this new Hydroxyzine, and am concerned that the father could have sent the wrong medication (possibly his own after recent surgery) for my nephew. The Hydroxyzine made my nephew very, very hyper and he had difficulty falling asleep both nights I gave this to him. My nephew made a comment that the pink pill was what he takes for sleep (Mirtazapine?) at home. Should I be concerned, or is Hydroxyzine given to children for sleep?? Thanks sooo much - I need to know if my nephew is bringing the right medication!
