Infant exposure was 0.9% to 2.3% of therapeutic maternal serum concentrations. If concurrent use is necessary, use the lowest effective doses and minimum treatment durations needed to achieve the desired clinical effect. In a separate case, one patient experienced sedation, confusion, disorientation, and slurred speech when clozapine was added to a regimen of valproic acid and lithium; discontinuation of valproic acid with subsequent re-initiation produced similar symptoms. The site is secure. Valproic acid and its analogs are hepatotoxic and are contraindicated in patients with hepatic disease or significant hepatic dysfunction. Less frequent administration (e.g., every 8 to 12 hours) may require close monitoring of trough concentrations. Depakote is known to interact with 740 drugs, out of which 21 drug interactions are major, 668 drug interactions are moderate, and 51 drug interactions are minor. 1990; Gram & Bentsen, 1985). These thoughts or behaviors occurred in approximately 1 in 500 patients taking the antiepileptic class of medications. Monitor patients closely for signs and symptoms of methemoglobinemia if coadministration is necessary. Estrogen may increase the clearance of valproic acid, possibly leading to decreased efficacy of valproic acid and increased seizure frequency. If valproic acid therapy is discontinued, lamotrigine doses may need to be adjusted upward. They may continue to monitor your liver function during your treatment. The free drug is responsible for tissue toxicity (rather than the total level in the blood). US-based MDs, DOs, NPs and PAs in full-time patient practice can register for free on PDR.net.
