3. How to Take It

1. Shake Well – The liquid is mixed, so shake before measuring.
2. Use a Calibrated Dropper or Oral Syringe – Accuracy is key; the dropper usually provides a 0.5 mL or 1 mL measurement.
3. Divide the Daily Dose – Most clinicians prescribe 2–3 daily administrations to keep blood levels steady.
4. Take with Food (if tolerated) – This may reduce nausea.

5. Serious Risks & Precautions

Issue	What It Means	Why It Matters
Liver toxicity	Elevated transaminases, jaundice	Can lead to fulminant hepatic failure.

Interaction	Effect	What to Do
Warfarin	↑ INR (bleeding risk)	Check INR more often; adjust warfarin dose.

7. Monitoring Plan (Typical)

1. Baseline: CBC, LFTs (AST/ALT), lipids, electrolytes, pregnancy test (if applicable).
2. First 3 months: CBC and LFTs every 2–4 weeks, then every 3–6 months once stable.
3. Therapeutic drug monitoring (if indicated): Serum valproic acid 12‑hour trough level to ensure therapeutic range (50–100 µg/mL in adults).
