24hrs (1 day ) so it takes 4-5 days to Steady state - if patient is outpatient she brings them back in a week and if they are inpatient she brings back in 4-5 days

Lithium has narrow range

0.8‐1.2 mEq/L acute
we push upper limit
people with mania have high elimination

Lithium andThiazides

Thiazides are the worst. they increase more than loops. we still use together but we have to watch lithium level

Labs Why Urinanalysis

Look at specific Gravity ( Nephro Diabetes insipidus

Depakote Dosing

have to hit hard since they dont have much time in hospital 20mg/kg (dont do baby dosing)

target blood levels of Depakote

shoot for 80-100 ng/ml

Depakote Lamotrigine interaction

Depakote and Pregnancy

it decreases them (thrombocytopenia)
and LFT-Hepatotoxicity - not as concerned until its 3-5 times

acute mania (equitro)

Carbamazapine dosing

200 mg PO BID

Carbamazapine - unique to

induces its own metabolism (levels may go down at end of month and you may have to increase dose
