Vet has us on a weaning OFF schedule for the phenobarbital AND immediately starting 50 MG zonisamide twice a day. Charalambous M, Shivapour SK, Brodbelt DC, Volk HA. It should be administered with food; the amount and type of food given should be kept constant, because variable dietary salt content will affect the elimination of bromide via the kidneys. Weaning a Litter of Puppies. doi: 10.1212/WNL.0b013e3181eccfb5, 25. von Klopmann T, Rambeck B, Tipold A. Capsules should be protected from light and be stored in a dry place. Tapering phenobarbital is crucial, because it is addictive and can result in withdrawal seizures if stopped abruptly. Zonisamide therapy for refractory idiopathic epilepsy in dogs. This may also support the possible dose-dependent nature of the aggressive episodes, given the reported elimination half-life of ZNS in dogs being approximately 15 h (6, 26). The regular maintenance dose can be started at the same time as the loading dose or immediately afterward. by SpencerBhumi Fri Aug 08, 2014 2:50 pm, Post (2017) 76:2431.

I will talk to the vet this week about the plan. Zonisamide was further increased to 7.5 mg/kg q12h due to a few events of cluster of seizures. In all species, it takes ~2 wk to approach a steady-state plasma concentration, because oral absorption is extremely variable and the half-life is long. Knudsen JF, Thambi LR, Kapcala LP, Racoosin JA. doi: 10.1016/0272-0590(88)90158-3, 19. Although psychiatric adverse effects including aggressive behavior associated with zonisamide are widely recognized in humans, this is the first report in dogs in the clinical setting. In addition to its anti-seizure potency, ZNS may be efficacious in treating various human neurological and psychiatric diseases including migraine, neuropathic pain, essential tremor, and Parkinson's disease (812). doi: 10.1111/j.1748-5827.2006.00290.x, 26.

Chronic migraine. Think about timing before deciding to wean off an anti-seizure medication. Depending on a childs seizure frequency, it is also a good idea to consider stopping seizure medication well before teens are at the age where driving becomes a possibility. As adjunct therapy with phenobarbital, potassium bromide can be administered at 2040 mg/kg/day, PO, either as one dose or divided into two or more doses; the sodium bromide dosage is slightly lower at 1730 mg/kg/day, PO. Neurology. It is created by eHealthMe based on reports of 8,997 people who have side . In dogs not on drugs that induce hepatic microsomal enzymes, the dosage is 5 mg/kg, PO, bid. I am pleased to hear that you have gotten through this - both recovering from pancreatitis and successfully switching the medications. BMC Vet Res. Although the drug appears safe, owners should be warned that because of the sulfonamide base, potential adverse effects (eg, keratoconjunctivitis sicca, bone marrow dyscrasia, hepatopathy, vasculitis, and metabolic acidosis) could occur. Bromide is renally eliminated and thus should not be used in dogs with renal dysfunction without careful monitoring. This dog had clinical onset of generalized seizure 12 days prior to referral. Making the decision to stop taking an anti-seizure medication (ASM) can be difficult. Levetiracetam (generic for Keppra), gabapentin, and zonisamide are the medications most commonly used in cases of refractory epilepsy.

Zonisamide for neuropathic pain in adults. The therapeutic range for bromide is 12 mg/mL (1020 mmol/L) with concurrent phenobarbital treatment, or 13 mg/mL (1030 mmol/L) for bromide as a monotherapy. The recommended dose and monitoring strategy are as follows: oral starting dose at 37 mg/kg every 12 hours (q12h) or 710 mg/kg q12h in dogs with co-administered hepatic microsomal enzymes inducers such as phenobarbital, serum concentrations should be aimed between 10 and 40 mg/L according to the human target range, and the serum concentration measurements should be performed at least 1 week after treatment initiation or dosage adjustment given the approximate elimination half-life of 15 h (6, 7). White JR, Walczak TS, Marino SE, Beniak TE, Leppik IE, Birnbaum AK. Severe withdrawal symptoms, even lethal seizures, may appear after abrupt discontinuation of chronic clorazepate treatment, in spite of the relatively low tolerance liability of clorazepate. For longterm maintenance in cats and dogs, phenobarbital may be given at 24 mg/kg/day, PO, bid. Begin by separating the puppies from their mother for a few hours at a time. Pediatr Neurol. It is primarily (70%) renally excreted in dogs, with the remainder of the drug undergoing hepatic metabolism. A serum sample can be submitted within 2 wk after loading to determine whether a therapeutic level has been reached. Because a daily maintenance dose may take 4 mo to reach steady state serum concentration, there are situations (eg, severe seizures, seizures that occur on a monthly basis, the need to rapidly switch from phenobarbital to bromide because of phenobarbital toxicity) when a loading dose of bromide should be administered. International veterinary epilepsy task force consensus proposal: medical treatment of canine epilepsy in Europe. doi: 10.1016/j.jfms.2008.01.006, 30.

Epilepsia. This is the first report describing abnormal behavior episodes, similar to PAE in humans, associated with ZNS in dogs in the clinical setting. Abnormal behavior episodes included sudden rage and aggression to the family members, insomnia, restlessness, and/or constant attention-seeking behavior. For maintenance therapy in dogs, it may be used alone at 0.5 mg/kg, tid, but it is best used as an adjunct to phenobarbital at dosages of 0.10.5 mg/kg/day. A graph illustrating the association between the dose of ZNS and the severity of episodic aggression in case 2. They are usually given to people with epilepsy only when other anti-seizure medications havent helped. Biton V. Clinical pharmacology and mechanism of action of zonisamide. Many drugs are commonly prescribed for off label use in veterinary medicine. Systemic Pharmacotherapeutics of the Nervous System, Maintenance Antiepileptic Drugs (Anticonvulsants). If the level is not within the middle of the therapeutic range, the dose should be increased before adding or switching to a new drug. The decision to start maintenance anticonvulsant or antiepileptic therapy should be based on the frequency and severity of the seizures, the age of onset, the likely cause(s) of the seizures, and the results of diagnostic testing. Seven days after the discontinuation of ZNS, the owner reported those frequent abnormal behavior episodes almost completely disappeared within 5 days after discontinuation of ZNS except for occasional gesture curling up the upper lip during the sleep for a few seconds. Zonisamide (brand name: Zonegran) is an anticonvulsant (antiseizure) medication that is either used as an initial therapy for epilepsy or as an add-on drug for difficult to control seizures. Clonazepam, unlike diazepam, can be used in dogs for oral maintenance therapy, because anticonvulsant tolerance develops less rapidly, the saturability of its metabolism reduces the elimination rate at therapeutic concentrations, and because it is more highly absorbed orally (particularly in micronized formulations). This pyrrolidine-based anticonvulsant has an unknown mechanism of action. Given the history and unremarkable clinicopathological analyses results, ZNS dose was reduced to 4.5 mg/kg PO q12h without any changes in LEV and glycerine to avoid multiple variables at one time for assessing the clinical response to the medication adjustment. If you decide to switch to a different medication, youll need to take both for a while to see how helpful the new medication is and how well you tolerate it.

When used in combination with phenobarbital, bromide toxicity can be seen at concentrations of 23 mg/mL (2030 mmol/L). (2007) 10:10510. In foals, phenytoin has erratic plasma concentrations. If seizures do recur, it is likely that they will be controlled again with medication. The adverse effects are usually mild, such as transient ataxia, loss of appetite, lethargy, and vomiting. Look for a well-known, name-brand puppy food that is not grain-free. Summary: Drug withdrawal syndrome is found among people who take Zonisamide, especially for people who are male, 50-59 old, have been taking the drug for 1 - 6 months. Critical differences are that 1) the dog's body adapts to zonisamide pretty quickly -- maybe 2 weeks -- and the ataxia goes away, and 2) the dose of zonisamide doesn't have to increase continually. 2015 ACVIM Small animal consensus statement on seizure management in dogs.

Treatment should begin with a single drug at the minimal required level for effect. Limitations of this report reside in the small number of cases, the retrospective nature, and difficulty in proving the direct association of abnormal behavior episodes and ZNS or in ruling out other potentially contributing conditions. This is the place for general questions about drugs, long-term treatment concerns, possible influences of other drugs (such as antibiotics, heartworm preventatives, or anesthetics) for epileptic dogs, and other concerns. The aggression was noted in the absence of precipitating causes or environmental triggers, occurring nightly predominantly toward females in the household. Many laboratory assays cannot distinguish between serum bromide and chloride ions, so serum chloride values may be reported as falsely high. A nonfatal hepatopathy in a dog was attributed to zonisamide. She's been on it so briefly, but who knows, the KBR may have caused it. In two recent reports on human medicine, LEV had the highest PAE risk (15.716.2%), which was significantly higher compared with those with other ASDs (38, 39). Tapering and withdrawing off benzodiazepines can be difficult, particularly after prolonged daily use. This dog bit the client on the arm multiple times. This may suggest that PAE or CAE are not necessarily associated with higher serum concentration of ZNS than the reference range. Zonisamide should be stored at 25C (76F).
