Mood Stabilizers Flashcards
Blood levels should be drawn about this many hours after the last dose of lithium
12 hours (Trough)
For maintenance treatment of Bipolar disorder, lithium levels should generally be above this
0.6-0.8 mEq/L
Before starting a young male patient on lithium, labs that should routinely be done are these
TSH & BUN/creatinine
In lithium maintenance treatment, ideally these labs are done 1-2 times per year
lithium level, TSH, BUN/creatinine
This lithium side effect can be worsened by caffeine or improved with propranolol treatment
tremor (resting or postural)
Unlike any antidepressant or mood stabilizer, Lithium treatment decreases patient’s mortality risk from this
suicide
Lithium toxicity with a lithium level greater than 4.0 mEq/L is treated with this
dialysis
To confirm therapeutic levels after starting lithium or increasing the dose, a lithium level should be done after this number of days
5 days
For patients taking lithium, renal impairment, sodium depletion, or dehydration all increase the risk of this
lithium toxicity
Divalproex Sodium (Depakote) exposure during the first trimester of pregnancy increases the risk this serious congenital anomaly
neural tube defect (spina bifida)
Before starting a male patient on Divalproex Sodium (Depakote), these two lab tests should be done
LFT’s & platelets
If Divalproex Sodium (Depakote) is added to the medication regimen of a patient who is taking Lamotrigine (Lamictal) this should be done.
decrease Lamotrigine dose by half
Propranolol 2-3x’s per day may be used to treat this common side effect of divalproex (depakote)
Tremor
The age range of patients most at risk for divalproex’s (depakote) side effect of serious, possibly fatal, hepatoxicity is this
under 2 years old
Patients on the generic form of valproic acid (depakene) are at greater risk of developing this side effect than those on the enteric coated divalproex (depakote)
GI side effects (N/V/D, GI discomfort)
Ironically, divalproex (depakote) is indicated as prophylaxis for this condition, which is also one of divalproex (depakote’s) common side effects
Headache (indicated for migraine prophylaxis)
For divalproex (depakote), while the trough level of the Immediate Release (IR) should be drawn 12 hrs after the last dose, the trough level of Extended Release (ER) should be drawn at this time
18 hour after the last dose Examples: - If IR-last dose 10pm, blood draw 10am - If ER-last dose 10pm, blood draw 4 pm
For a patient taking Divalproex Sodium (Depakote), taking aspirin increases the risk of this
decreased platelets (Thrombocytopenia)
