Strattera dose adjustment | ADHD Information

My DS who is 7 has lost almost 5 lbs on strattera and gets stomach aches.. he does was 25mg, we have backed down to 10mg twice a day.. it isn't working as well.. but, we are going to give it a shot.. I don't want to change meds over the holidays... Last week my son had his neuroped appointment and his Strattera dose was changed. He went forn 18mg to 25mg. He weights about 23kg. Now, this week I am starting to notice him more hyper in the afternoons, and again with eating issues. His lunchbox came exactly the same today as I have set it this morning. We had a little argument over lunch and then he started complaining about stomach ache. It feels the same as when he started taking Strattera for the first time. Is this normal when the dose is changed? Anyone with a similar experience? Mariaven39049.5572106481
