Hi!Wendy-LeeMy SW dd is almost 8 yrs old too; she weighs about 64 lbs and has just had her meds increased to 15 mg per day. We break this up every 6 hrs, as we’re following the circadian method for the time-being anyway. Her testosterone levels have been fine thus far, but her renin was high at her last bloodwork, so we’ve upped her florinef to 1&1/2 tablets per day. Hope that helps!
