An abnormal behavior episode of case 2 right after getting on the client's lap. This dog had an episode of cluster seizures. Precautions. Felbamate is a dicarbamate AED that exerts its anticonvulsant effects through multiple mechanisms, including potentiating GABA-mediated neuronal inhibition, inhibiting voltage-sensitive neuronal calcium and sodium channels, and blocking N-methyl-d-aspartatemediated neuronal excitation. Introduction. Tapering phenobarbital is crucial, because it is addictive and can result in withdrawal seizures if stopped abruptly. I'm so sorry that you had to go through all of this, but so happy to hear that she's coming home! (2017) 76:2431.

Give her 3/4 of the regular dose for a few weeks, then a half dose for a few weeks, then a 1/4 dose for a few weeks. However, cats not only have a longer half-life (1520 hr) than dogs but also do not develop a tolerance to the anticonvulsant effects. Zonisamide discontinuation due to psychiatric and cognitive adverse events: a case-control study. Daily seizure episodes resolved after ZNS was added. This dog had no pre-existing abnormal behavior problems before and no seizure episodes were witnessed in association with these behavior episodes. This medication should be used with caution in nursing mothers, as it is unknown at this time if zonisamide is excreted in maternal milk. (2014) 10:257. doi: 10.1186/s12917-014-0257-9, 33. Key factors to consider include the type of epilepsy you have, the number of medications you tried before becoming seizure-free, and your EEG tests. Prior to this, she had never had a partial seizure and her seizures were usually several hours apart. doi: 10.1111/j.1939-1676.2011.00801.x, 18. This dog bit the client on the arm multiple times. (2003) 23:936. But, taking them daily may cause drowsiness, dizziness and loss of balance, and other side effects. In dogs not on drugs that induce hepatic microsomal enzymes, the dosage is 5 mg/kg, PO, bid. If the puppies do not take to the gruel, try blending this ratio: 2 cups of puppy food. (2006) 68:S39. In dogs, the dosage can be increased every 2 wk in increments of 20 mg/kg if therapeutic benefit has not been noted. Epilepsia. The goal is to prevent seizures with as few side effects as possible. A 6-year-old female spayed miniature poodle weighing 5.05 kg was referred to Veterinary Specialists and Emergency Center for episodic aggression. (2014) 21:889. Episodes showed no response to acepromazine (unknown dose or route). (2012) 60:3579. doi: 10.2460/javma.251.12.1457, 28. When bromide is used as the sole treatment for epilepsy in dogs, higher dosages (5080 mg/kg/day) may be necessary. Blastomycosis is a Systemic Fungal infection Affecting Dogs and Cats Bloat - The Mother of All Emergencies Bloat: First Aid Bloody Nose (Epistaxis) in Dogs and Cats Bones are Unsafe for Your Dog, No Bones about It Brachial Plexus Avulsion in Dogs and Cats Brachycephalic Airway Obstruction Syndrome in Flat-Faced Dogs Severe bromide toxicosis (bromism) is characterized by lethargy, disorientation, delirium, and ataxia progressing to quadriplegia and coma. Weaning off Gabapentin requires you to do so slowly. In some cases, the asthmatic changes were fatal, but in most cases the signs resolved after discontinuation of bromide. Epilepsy Res. 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). Spencers last two clusters have changed. The dosage in cats has varied from 5 mg/kg, PO, bid, to 510 mg/kg/day, PO. Its use in cat and dogs to treat seizures is 'off label' or 'extra label'. doi: 10.1007/s00415-012-6628-x, 12. Current indications include adjunctive therapy for partial seizures in adults. In these instances, follow your veterinarians directions and cautions very carefully as their directions may be significantly different from those on the label. 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). Bromide appears to stabilize neuronal cell membranes by interfering with chloride transport across cell membranes and by potentiating the effect of GABA via hyperpolarizing membranes. The recommended initial dosage is 15 mg/kg, PO, tid, but the dose can be increased every 1421 days in increments of 15 mg/kg if therapeutic benefit has not been noted. Doing this may increase your risk of having more frequent and/or severe seizures. doi: 10.1212/WNL.0b013e3181eccfb5, 25. von Klopmann T, Rambeck B, Tipold A. Taking multiple medications can reduce quality of life because of side effects, drug interactions, and cost. Zonisamide is available as capsules of 25, 50 and 100 mg .

A serum sample can be submitted within 2 wk after loading to determine whether a therapeutic level has been reached. Negative effects of epilepsy and antiepileptic drugs on the trainability of dogs with naturally occurring idiopathic epilepsy. The severity and frequency of the episodic aggression showed proportional relationship with the dose of ZNS. doi: 10.1002/14651858.CD011241.pub2, 11. The likelihood of future seizures in children with epilepsy is based on specific factors like the underlying cause, epilepsy syndrome, and seizure type. Bromide toxicity can be seen at any concentration in an unusually sensitive dog, but it is rare when bromide is used alone and when serum concentrations are < 1.5 mg/mL (15 mmol/L). Phenobarbital has a long record of safety, efficacy, low cost, and convenience in regard to monitoring serum concentrations. This dog was managed well with PB (2 mg/kg q12h) and LEV (20 mg/kg q8h) with no observable epileptic or aggressive behavior episodes for 13 months until this dog died of an unrelated condition. Zonisamide - induced urinary lithiasis in patients with intractable epilepsy. Hopefully we are out of the woods with the pancreatitis. by readerofthepack Wed Aug 13, 2014 8:29 am, Post Due to serious detrimental impact on the family, ZNS was discontinued abruptly as a therapeutic trial with our concern of possible association between the episodic aggression and ZNS. by athomas989 Fri May 29, 2015 1:59 pm, Post Our case 2 did not have MRI or cerebrospinal fluid analysis to rule out other intracranial structural conditions, which was clinically considered relatively unlikely given stable condition through a long follow-up duration of this case. Another week later, the owner reported the increasing frequency and the change in the episodic abnormal behavior. Do not stop this medication suddenly or else seizures may occur. . doi: 10.1016/S0887-8994(02)00511-8, 22. 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. Please note that we cannot make specific recommendations for individual dogs - for this, please consult your veterinarian. What worries me is he is on metronidazole (weaning off per vet), metoclopramide, ranitidine, simethicone and thyroxine, plus the zonisamide. Ten more days later, the owner described that abnormal behavior episodes were deteriorating in the following aspects: increasing in frequency to daily events, not limited to during the sleep, and deteriorating in its severity to bite the owner on her arm severe enough to visit an emergency hospital. Nonetheless, the proportional association between ZNS dose and the severity of the clinical signs was shown with multiple dose adjustments in this case. In human medicine, there were several reports of psychiatric and behavioral side effects associated with ZNS (1, 24, 3336). Murata M, Hasegawa K, Kanazawa I. Zonisamide improves motor function in Parkinson disease: a randomized, double-blind study. It is typically used twice daily in dogs, usually as a supplement to phenobarbital. Begin by separating the puppies from their mother for a few hours at a time.

This time may increase if your pet has decreased liver or kidney function. & Public Policy Institute, How long youve been taking medicine for seizures, How your medications affect your quality of life. Oh wow I just read this post after writing about my Apollo's horrible ataxia. Phenobarbital (PB) at 1.5 mg/kg q12h was added at this point concerning these abnormal behavior episodes as an atypical manifestation of sensory epileptic events. This synthetic analogue of the inhibitory neurotransmitter -amino butyric acid (GABA) inhibits seizure activity via multiple mechanisms, including inhibition of neuronal sodium channels and potentiation of the release and action of GABA. Adverse effects consist of sedation only, but periodic hematologic monitoring is advised, because blood dyscrasia and hepatotoxicity are reported in people. 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. *Correspondence: Shinichi Kanazono, kanazono@vsec.jp, View all For me, the side effects of Zonegran far outweighed the positive. However, there may be a risk that your seizures will return after weaning off.

KBr is associated with pancreatitis and megaespohagus. Using this medicine while you are pregnant can harm your unborn baby. 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. Routine bloodwork consisting of CBC and serum biochemical analysis were within the reference intervals. by ShilohsMom Wed Aug 13, 2014 8:35 am, Post by seebr5640 Sun Jun 30, 2013 1:08 pm, Post Similarly, a case series study described abnormal behavior episodes in dogs receiving LEV (40). J Neurol. If they are not available, follow their directions in contacting an emergency facility. CBC, serum biochemical analysis, and urinalysis were within the reference intervals. CNS Drugs. The phenobarbital metabolite is likely the major functional one, and there may not be an advantage to using primidone over phenobarbital. If excessive sedation occurs, a lower dose should be used initially and gradually increased. Per rectal diazepam: Some epileptic dogs have a tendency to experience "cluster seizures" (two or more seizures in a 24-hour period) even when being treated with Phenobarbital and potassium bromide. by readerofthepack Fri Aug 08, 2014 1:32 pm, Post Zonisamide was prescribed with the gradual dose increment plan potentially up to 13.7 mg/kg q12h if needed based on his seizure frequency. (2018) 200:10613. Changes in brain serotonin and dopamine levels are considered as a mechanism of ZNS-induced PAE (24, 35, 37) and human patients with a history of psychiatric disorder had significantly greater risk of developing PAE associated with ASDs including ZNS (24, 36, 38, 39). 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. Don't really have much to add to what has been said, other than to say welcome and I will keep you all in my prayers. (2003) 28:1849. 1 Its mechanisms of action include inhibition of voltage-dependent sodium and T-type calcium channels. Owners should keep a calendar to document the frequency and pattern of seizures as a guide for treatment strategy. Bromide (potassium or sodium salt) can be used as a first-choice AED in dogs with epilepsy, as an adjunctive AED in dogs with refractory seizure disorders, or for dogs that have unacceptable adverse effects related to phenobarbital or other AEDs. It is very important that your doctor check your progress at regular visits to see if the medicine is working properly. Hepatic failure is rare. The principle advantage of felbamate is a lack of sedation, and adverse effects are reportedly rare. Cochrane Database Syst Rev. Basset/Beagle mix was officially pegged with epilepsy about 2 months ago after she started having multiple seizures in a day. Because it does not undergo hepatic metabolism, bromide is useful in dogs with liver disease. 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. The aggressive episodes deteriorated day by day over the next 5 days until ZNS dose was reduced to 5 mg/kg PO in the morning and 2.5 mg/kg PO in the evening. The recommended therapeutic range is 1040 mg/mL; trough concentrations can be measured ~710 days after initiating treatment or altering the dosage. Brain Dev. In dogs, the initial dosage is 1015 mg/kg, PO, tid. Erath JR, Nessler JN, Riese F, Hnerfauth E, Rohn K, Tipold A. Behavioral changes under levetiracetam treatment in dogs. doi: 10.1111/j.1468-2982.2006.01191.x, 13. I've read both that the KBr on its own can cause pancreatitis and that it's the combo of KBr & phenobarb that can cause the pancreatitis. Seven days after complete discontinuation of ZNS, abnormal behavior episode completely disappeared, and the appetite was recovered by 80% according to the owner. Mephenytoin, although related to phenytoin, has been effective in dogs (10 mg/kg, tid) because of a slower rate of elimination. Levetiracetam (generic for Keppra), gabapentin, and zonisamide are the medications most commonly used in cases of refractory epilepsy. by SpencerBhumi Sat Jul 13, 2013 9:17 am, Post In dogs, it has excellent oral bioavailability, does not appear to undergo hepatic metabolism, is primarily excreted unchanged in the urine, and has a half-life of ~4 hr. The abnormal behavior episodes deteriorated along with gradual dose increment of zonisamide and these episodes almost completely disappeared within 5 days after discontinuation of zonisamide. This will begin to lessen the puppies' dependence on their mother's milk and presence. doi: 10.2736/jjvd.24.147, 14. Effective serum levels are determined by the serum level of phenobarbital (1545 mcg/mL). J Vet Intern Med. Call our Epilepsy and Seizures 24/7 Helpline and talk with an epilepsy information specialist or submit a question online. The authors thank the owners of three cases, referring veterinarians and colleagues at Veterinary Specialists & Emergency Center for supporting us for the article preparation. The regular maintenance dose can be started at the same time as the loading dose or immediately afterward. Although plasma concentrations declined rapidly in dogs on a 1-wk regimen of 30 mg/kg, tid, one case report described adequate seizure control despite undetectable drug concentrations in plasma, possibly due either to an active metabolite or to a highly sensitive drug reaction. The medication should begin working within 1-2 days. Packer RMA, McGreevy PD, Pergande A, Volk HA. Dermatol. Kwan SY, Chuang YC, Huang CW, Chen TC, Jou SB, Dash A.

Repeat this process two or three times a day until they begin to drink the milk replacer on their own. Brodie MJ, Duncan R, Vespignani H, Solyom A, Bitenskyy V, Lucas C. Dose-dependent safety and efficacy of zonisamide: a randomized, double-blind, placebo-controlled study in patients with refractory partial seizures. Zonisamide may be given in combination with other . Within another week, the abnormal behavior episodes completely disappeared. There is no clinical information on use of felbamate in cats. 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. Because the elimination half-life is short in dogs (24 hr), it is probably not an effective anticonvulsant, but a dosage of 510 mg/kg, bid, has been suggested. doi: 10.3988/jcn.2007.3.4.175, 4. No similar episodic aggression was witnessed in association with dose adjustments or addition of other ASDs including PB, potassium bromide, and LEV.

Valproic acid (1060 mg/kg, tid) has been used as an adjunct to phenobarbital and primidone in dogs with refractory seizures. Addition of LEV (27 mg/kg PO q8h) and glycerin (5 ml/head PO q8h) did not alter the abnormal behavior and decreased appetite. Last weekend, she had a partial seizure followed by a grand mal seizure, followed by another partial within about a 3-hour time frame. The severity of episodic aggression was determined based on the client's oral description at each follow-up; 100% at the initial presentation. Clorazepate dipotassium (0.51 g/kg, tid) has been proposed as an adjunct to phenobarbital treatment in dogs. In addition, aggression has been reported in a research setting investigating chronic toxicity of ZNS in dogs (18). It's so hard to give them medications we know might not be good for them, but on the other hand, them not having them could be bad for them. J Am Vet Med Assoc. The plan now will be to wean the Zonisamide. It was also interesting that the average maximum ZNS serum concentration in patients who discontinued ZNS attributable to PAE or CAE was significantly lower than maximum ZNS concentration of control group in the aforementioned study (24). The nightly episodic aggression completely disappeared within 5 days after discontinuation of ZNS. If you can find something other than KBr try that first, my boy had so many issues from the KBr, but sadly it seemed to be the only drug that gave him a reprieve and also the one that I'm convinced caused the problem that caused his passing. Epilepsy is a neurological disorder in which the electrical activity of the brain is disturbed causing seizures. Diarrhea sometimes develops with clonazepam, but this may be avoided by starting with once daily dosing and increasing the frequency to three times daily over a period of several days. Copyright 2021 Kanazono, Ukai and Hiramoto. Thus, diazepam can be used as a maintenance treatment in cats, with dosages ranging from 0.250.5 mg/kg, PO, bid-tid. For the relief of ankylosing spondylitis, the recommended dosage of Voltaren (diclofenac) is 100-125 mg/day, administered as 25 mg four times a day, with an extra 25-mg dose at bedtime if necessary. Prior to referral, this dog had been on ZNS at the dose of 10 mg/kg PO q12h for presumptive idiopathic epilepsy over the past 3 years and epilepsy had been extremely well-controlled with no seizure episodes witnessed. Its use in cat and dogs to treat seizures is 'off label' or 'extra label'. Bromide, phenobarbital and zonisamide are examples, although phenobarbital and zonisamide half-life may get short enough that timing is important. After failing to control daily epileptic episodes with PB, LEV, and potassium bromide over the next 10 days, ZNS at 50% reduced dose (5 mg/kg PO q12h) was resumed to confirm the direct association between ZNS and the aggressive episodes as well as to manage seizure episodes. 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. by MK's mom Fri Jun 05, 2015 2:01 pm, Return to Treatment & Maintenance Issues for Epileptic Dogs.

The option that is best for you depends on several factors: In general, it is better to control seizures with a single medication. You can dip your finger in the formula and wet the puppies' noses and mouths. Disposition and safety of zonisamide after intravenous and oral single dose and oral multiple dosing in normal hound dogs. In general, a maintenance antiepileptic drug (AED) should be considered in animals that have had more than one or two seizures within a 6-mo period (assuming these seizures were not caused by repeated toxin exposure) or in animals that have had more than one seizure of unknown cause on any particular day. Contact your veterinarian immediately if your pet stops eating, becomes dramatically lethargic, or develops a yellow color of the skin, gums, or whites of the eyes.
