A parent of a 15-year-old boy with ADHD said atomoxetine, despite some side effects, was when his ADHD symptoms improved the most. He no longer takes it and again sometimes forgets appointments with friends.

A parent's son with ADHD had settled on a maintenance dose of liquid atomoxetine but found it increasingly bitter. They switched to tablets, which meant a slightly higher dose, and chose this to respect the child's preference.

The daughter is back on Strattera. It keeps impulsivity under control, but her focus stays low, so lesson content doesn't stick and school remains difficult.

    Where this comes from

    We only pick posts in which parents describe trying something with their own child, from public parent forums and personal blogs. We don't copy the posts: we pull out the result, duration and side effects, write a short summary, and link every review to its original. These are parents who chose to write, so the numbers may differ from the real picture.
