Thank you all for the help, we’ve been back n forth to pediatric neurologist hospital & did a long EEG for 3 days & she was miss diagnosed, she was having intractable seizures so they've lowered some meds & eliminated some of her 4 meds plus 4 breakthru meds to epidiolex & its been a game changer, shes developed some tics from the string meds but hopefully they’ll disappear too.. thank God, keeping our fingers crossed & so thankful to have our little bean back & she can have a better quality of life.. Thank you all & God Bless ♥️🙏

Definitely through blood draw then lab work.

Yes through blood work, they check to see if your meds are at a therapeutic level or not..
Hope all is well & have a wonderful thanksgiving

Through blood work.

I got my Lamictal levels checked often when I was pregnant.
