Valproic acid side effects. Eliminated by first-order kinetics at therapeutic ranges. FOIA The complex metabolism of valproic acid leads to much of its associated toxicity. Valproic acid and its metabolites can affect structures in the mitochondrial membrane​28,29​, and in rodent models the valproic acid impaired activity of cytochrome oxidase (cytochrome C) in the electron transport chain (Figure 3).​30​ The effects on cytochrome oxidase C are hypothesized to contribute to the seizure activity noted in these patients.​25​ Additionally, there are case reports where valproic acid can precipitate hepatic failure in patients with mitochondrial disorders.​31​ Given this, it makes sense that patients with fragile mitochondria would be at higher risk for decompensation with a standard dose of valproic acid tipping them over the edge. During the process of mitochondrial β-oxidation, VPA depletes carnitine stores. I have yet to find answers intended for the layman such as myself.
