My 5 year old son just started on meds for ADHD. He is currently on Metadate 40mg. When we upped his dose from 30mg to 40mg, he started picking at his nails/chewing his nails. He told me it feels like a bumble bee or tarantula is under his nail & it hurts. After he stopped picking at his nail, I asked if it felt better and he said yes. I mentioned it to his doctor & did some googling but all I could find was where ppl with ADHD fidget/nite nails but didn’t find anything about where meds cause it. He was not doing this before. His dr said we can go down a dose but didn’t mention it’s a common side effect of meds. His teacher told me one day he wouldn’t do his work because he was so focused on his nail. Has this happened to anyone’s child & if so, what did you do?? Thank you!!
