<s>[INST] My 8 yr old daughter was just put on intuniv for ADHD a week ago. Just increased yesterday to 2mg. Normally, she is an animal lover (big time) and would never dream of hurting one. But today she threw our kitten down hard and it landed on it s back. She immediately started crying and said she doesn t know why she did that and she was afraid she had hurt him. She also came to me later in the day, crying, saying she wants to throw the kitten again and she doesn t know why. She has been extremely upset all day. She even said she may have to give away the kitten b/c she s afraid she will hurt him. Could this behavior have anything to do with the intuniv? [/INST] intuniv can cause irritability.watch the patient and if irritability continues can change to atmoxetine .regards.dr sarath s nair </s>
