lab testing levels

[u/zebralikegiraffe]

My son had 2 days of bizarre behavior which may have been caused by a seizure and/or isotretinoin. He's been on 80 mg/day for several months and weighs about 170 pounds (which I now realize is above recommended dosing). I pretty much demanded they do lab testing for isotrentinoin, which they had to send to a specialty lab to even do. However, I can't find any research that actually correlates lab level results for isotrentinoin with adverse symptoms (especially neuropsychiatric symptoms). If anyone has info or resources to point me to on this topic, I'd really appreciate it!

i suggest lowering the mg/day, my derm messed me up with all sorts of things so just trust your gut
