In about 9 percent of the reports involving neurologic signs, the pet died naturally or by euthanasia. DG, CR, MS, MH, and JG discussed the case and drafted the manuscript. Welling PG. Adverse side effects are thankfully rare and usually mild; however, there have been implications of seizures following administration of Bravecto so this should be avoided with pets who have a history of neurological disorders. PubMed Central  1996;16:383–415. This prolonged activity of the active compound may be explained by its pharmacokinetic properties. However, in pivotal effectiveness studies of fluralaner [7], various dog breeds and mongrels were included and no obvious differences in drug safety across breeds were noted. McGonigle I, Lummis SC. Article  In this case, improvement of the dog’s condition and disappearance of neurological dysfunction might simply be explained by drug elimination and decline of the relevant drug concentration in the brain. Every known insecticide/pesticide chemical has been shown to have severe neurological side-effects. It is important to make sure that the right product is used, the FDA said. Fed and fasted gastric pH and gastric residence time in conscious beagle dogs. Bravecto may cause these adverse effects: Most Common 1. The active poison in Bravecto (fluralaner) is a so-called "lipophilic" chemical poison. 2014;62(5):1019–24. The FDA considers products in the isoxazoline class to be safe and effective for dogs and cats but is providing this information so that pet owners and veterinarians can take it into consideration when choosing flea and tick products for their pets. With that in mind, here are some of the possible side effects that Bravecto can cause: Vomiting – Although Bravecto has shown to be readily eaten by most pets immediately through the chewable tablet even without mixing it food, there is a very slim chance of it causing your pet to vomit. 2012;287(48):40232–8. Sieghart W. Allosteric modulation of GABAA receptors via multiple drug-binding sites. Isoxazolines are potent inhibitors of gamma-aminobutyric acid (GABA)- and glutamate-gated chloride channels in the nervous system of invertebrates [3]. 2013;26(4):514–6. The current CVMP (Committee for Veterinary Medicinal Products of the European Medicines Agency) statement notes that convulsions and lethargy have been reported very rarely in spontaneous pharmacovigilance reports and emphasizes that Bravecto® should be used with caution in dogs with pre-existing epilepsy. One of the approved pharmaceuticals containing fluralaner is Bravecto®, which is available as chewable tablet for the treatment of tick and flea infestations in dogs [7]. Google Scholar. Suspected neurological toxicity after oral application of fluralaner (Bravecto®) in a Kooikerhondje dog. This can provoke neurological toxicity in MDR1 mutant dogs even at standard dosage, as it is well known for drugs like ivermectin [20]. However, as fluralaner has a generally good safety profile and neurologic adverse events only occur in very rare cases, individual factors increasing the drug concentration in the brain or increasing the susceptibility of CNS Cys-loop receptors may come into account. ADE Adverse Drug Events, Go to the Facebook Group. One of them is a defect of the multidrug resistance (MDR1) drug efflux carrier at the blood-brain barrier (commonly referred to as MDR1 nt230(del4)), frequently present in Collie, Australian Shepherd, Shetland Sheepdog, Longhaired Whippet, White Swiss Shepherd and some other breeds [18], which leads to increased drug penetration into the brain [19]. About 5,400 of the reports cite one or more neurologic signs, such as ataxia, muscle tremors and/or convulsions. Correspondence to Parasit Vectors. AAPS J. Kleintierpraxis. BMC Vet Res 15, 283 (2019). These products are approved for the treatment and prevention of flea infestations, and the treatment and control of tick infestations. Nonetheless, signs of neurological toxicity, including tremor, ataxia and convulsions have been observed in a target animal safety study for sarolaner at overdose [6]. As isoxazoline drugs target neuronal chloride channels with a clear preference for invertebrates, they are considered to have a good safety profile. 2014;7:83. https://doi.org/10.1186/1756-3305-7-83. Fleischer S, Sharkey M, Mealey K, Ostrander EA, Martinez M. Pharmacogenetic and metabolic differences between dog breeds: their impact on canine medicine and the use of the dog as a preclinical animal model. The site, Is Bravecto Safe? In general, the dog owner should be informed about possible adverse drug reactions after treatment with Bravecto® and an individual benefit-risk assessment must be performed. These drugs are considered safe because they are supposedly only toxic to the nervous system of insects. Veterinarians have been aware of the side effects of the Nexgard for dogs and Epi-Pen for humans for some time. Fluralaner (syn. The dog had received 40 g of pellet food (Platinum©) approximately 1.5 h prior to treatment. I’ve been practicing for 20 years. We thank Edda Wacker for critical reading of the manuscript. All symptoms were transient and the dog fully recovered without any treatment after 10 h. This case report may help to better classify adverse drug reactions after application of isoxazoline drugs and documents a good prognosis even after occurrence of severe neurological dysfunction in the present case. Furthermore, administration of an intravenous lipid emulsion (ILE) might be helpful. Before sharing sensitive information, make sure you're on a federal government site. Although the new isoxazoline drug fluralaner (Bravecto®) is generally well tolerated in dogs, adverse drug reactions involving neurological dysfunction occurred in individual dogs. In order to prevent enterohepatic re-circulation of fluralaner, administration of activated charcoal might also be useful. Nevertheless, it cannot be excluded that fluralaner also interacts with one of the vertebrate Cys-loop receptors in vivo, which are highly or even exclusively expressed in the central nervous system [16, 17]. Additional factors which limit drug tolerability are either unknown so far or are not relevant for the present case (feeding status, MDR1 genotype). 2002;62(10):1481–502.

Symptoms of neurological issues. Insect gamma-aminobutyric acid receptors and isoxazoline insecticides: toxicological profiles relative to the binding sites of [(3)H]fluralaner, [(3)H]-4′-ethynyl-4-n-propylbicycloorthobenzoate, and [(3)H]avermectin. Gaens, D., Rummel, C., Schmidt, M. et al. Arthropod Cys-loop receptors are targeted by many different antiparasitic drugs, including fipronil, ivermectin, and fluralaner [2]. Fluralaner inhibits arthropod glutamate-gated chloride channels (GluCls) and GABA-gated chloride channels (GABACls) [12], which structurally belong to the class of so-called Cys-loop receptors [13, 14]. https://doi.org/10.1074/jbc.R112.406280. GOVC has sold thousands of doses with no reported neurologic side effects. On the medication leaflet of Bravecto (tablet) only the following side effects are indicated: “Vomiting, Decreased appetite, Diarrhea, Lethargy, Polydipsia, Flatulence”.
