Addition of LEV (27 mg/kg PO q8h) and glycerin (5 ml/head PO q8h) did not alter the abnormal behavior and decreased appetite. I do fear removing a drug completely since things have been "okay" lately -- but with Apollo having such bad ataxia this past week it is certainly making me concerned My boy has done marvelous on the zonisamide with no side effects, but my other epileptic who has passed away didn't get much of a break from seizing with zonisamide, they're all so different.

Tapering and withdrawing off benzodiazepines can be difficult, particularly after prolonged daily use. The goal is to prevent seizures with as few side effects as possible. As for type 3 adverse effects, the possibility of affecting thyroid function (especially decrease in total T4) and the changes in blood chemistry profile within the reference range, including the elevation of ALP and Ca and the decrease of total protein and albumin compared with those prior to the administration of ZNS, were observed (7). Acute hepatic failure has been reported in cats given diazepam for behavioral problems; thus, a pretreatment chemistry profile should be evaluated before using diazepam, and cats should be watched closely during the first 2 wk of use. A review article reported the most common adverse effects pertained to the CNS were ataxia, dizziness, somnolence, agitation, and anorexia (36). Bromide has been used in horses as a maintenance AED, but there are no published studies on its clinical efficacy.

Reports of hindlimb weakness should be investigated as potential bromide toxicosis by measuring serum bromide concentration and discontinuing bromide for several days to see whether the weakness improves. Serum concentrations of zonisamide should be measured minimally 1 week after treatment initiation or dosage adjustment to allow steady state concentrations be reached.
