🧪 Labs
Monitor LFTs baseline + serial
↑ Ammonia → encephalopathy

Bruising, bleeding gums
Pancreatitis → severe abd pain
📌 Avoid
Pregnancy → neural tube defects
No abrupt stop → seizures
📚 Valproic Acid — full study notes
The cheat sheet above is your quick recall card. These notes go deeper — what it is, what to do first, what must be reported, and what to teach.
Valproic acid is an anticonvulsant also widely used as a mood stabilizer for bipolar disorder (mania) and for migraine prophylaxis. It requires monitoring of serum levels, liver function, and platelets because of risks of hepatotoxicity, pancreatitis, and thrombocytopenia. It is highly teratogenic (neural tube defects) and is avoided in pregnancy.
🔑
Key points
Understand these first
Therapeutic serum level is 50-100 mcg/mL (some sources up to 125); levels are monitored routinely.
Risk of hepatotoxicity and pancreatitis - monitor LFTs and watch for abdominal pain/nausea.
Can cause thrombocytopenia; monitor platelet counts and watch for bruising/bleeding.
Highly teratogenic (neural tube defects); contraindicated in pregnancy - women need effective contraception.
Used both as an anticonvulsant and as a first-line mood stabilizer for acute mania.
Causes GI upset, sedation, weight gain, tremor, and possible hair thinning.
✅
Nursing priorities
What to do, in order
Monitor serum valproate levels and report values outside the therapeutic range.
Monitor liver function tests and platelet/CBC results.
Assess for signs of pancreatitis (severe abdominal pain, vomiting) and hepatotoxicity (jaundice, anorexia).
Verify pregnancy status and counsel on contraception due to teratogenicity.
Give with food to reduce GI upset; do not crush extended-release tablets.
🚩
Red flags — report now
Escalate immediately
Signs of hepatotoxicity: jaundice, dark urine, severe fatigue, anorexia - report immediately.
Signs of pancreatitis: severe epigastric/abdominal pain, persistent vomiting - report now.
Unusual bruising or bleeding (thrombocytopenia).
Use in pregnancy - contraindicated due to neural tube defect risk.

Labs & values
Numbers to know
Valproic acid level 50-100 mcg/mL (therapeutic)
AST/ALT (monitor for hepatotoxicity)
Platelets 150,000-400,000/mcL (monitor for thrombocytopenia)
Ammonia (elevation may indicate hyperammonemic encephalopathy)

Patient teaching
What patients must know
Keep all lab appointments for drug levels, liver tests, and platelet counts.
Report yellowing of skin/eyes, severe abdominal pain, or unusual bruising/bleeding.
Take with food and swallow extended-release tablets whole.
Use reliable contraception and tell the provider if pregnancy is possible - this drug causes birth defects.
❓ Valproic Acid: NCLEX FAQs
What are the priority nursing interventions for Valproic Acid?
