Using PHENobarbital together with gabapentin may increase side effects such as dizziness, drowsiness, confusion, and difficulty concentrating. Some people, especially the elderly, may also experience impairment in thinking, judgment, and motor coordination. A commonly prescribed anti-seizure medication, phenobarbital makes the body produce more CYP enzymes, which increases the clearance and decreases the effectiveness of many types of medications, including digoxin, glucocorticoids, amitriptyline, clomipramine, theophylline, and lidocaine. Phenobarbital (Brand Name: Solfoton) is a barbiturate used to treat or prevent seizures. Phenobarbital is also used short-term to treat insomnia, or as a sedative before surgery. Phenobarbital is available in generic form. What Are Side Effects of Phenobarbital? Common side effects of phenobarbital include: dizziness, drowsiness, Often phenobarbital alone is used to start. If the seizures continue, then second or third line agents are used. With your case, if the seizures are continuing despite your therapy, another EXCELLENT option is to use KEPPRA. Gabapentin is well absorbed after oral administration in dogs 10 mg/kg every 8 h resulted in a significant decrease in the number of seizures per week and the number of days per week with any generalized seizures refractory to Phenobarbital and Find patient medical information for Phenobarbital on WebMD including its uses, side effects and safety, interactions, pictures, warnings, and user ratings In dogs, phenobarbital and bromide are considered first-line maintenance AEDs, but levetiracetam and zonisamide are often used as well. In cats, phenobarbital is the usual first choice, but levetiracetam and zonisamide are becoming more acceptable; diazepam is an alternative choice. Other anticonvulsant drugs are available for the control of seizures in dogs. These include the benzodiazepine family, gabapentin, valproic acid and felbamate. Because of resistance, side effects or increased frequency of administration, these drugs are not our primary choice for the treatment of seizures in dogs. Addition of gabapentin to phenobarbitone and/or potassium bromide increased the interictal period and shortened the post-seizure recovery in some canine epileptics. In some dogs, seizures were prevented completely, while in others there was an increase in interictal period. Gabapentin is well absorbed in both dogs and people, with peak serum concentrations occurring within 1–3 hrs after ingestion. In people, virtually all the orally administered dose of gabapentin is excreted unchanged in the urine (i.e., no hepatic metabolism). Phenobarbital side effects. Phenobarbital may cause a severe allergic reaction. Stop taking phenobarbital and get emergency medical help if you have signs of an allergic reaction: hives; difficult breathing; swelling of your face, eyes, lips, tongue, or throat. Phenobarbital may cause serious side effects. Call your doctor at once if you have: In this article we will describe “second-line” anti-epileptic medications, such as gabapentin, pregabalin, levetiracetam and zonisamide, which veterinary surgeons can use in combination with phenobarbital and/or KBr in epileptic patients with poorly controlled epileptic seizures. The elimination half-life of gabapentin in dogs is 3-4 hours in dogs, meaning that it may be difficult to attain steady state levels in dogs even with tid dosing. The dose at present estimated to be necessary to achieve some effect in dogs is 30 to 60 mg/kg divided tid to qid. More recently, several human drugs, such as gabapentin and levetiracetam, have been evaluated for seizure therapy in veterinary patients. This article will discuss anticonvulsant drug use in dogs with so-called 'refractory' or 'intractable' epilepsy. Phenobarbital is a member of the barbiturate drug class that holds versatile therapeutic applications. This drug is effective in anti-seizure management, treatment for status epilepticus, and insomnia; it also plays a pivotal role in addressing benzodiazepine and alcohol withdrawal. This mechanism involves interaction with GABA-A receptor subunits, facilitating the sustained opening of Phenobarbital, also known as phenobarbitone or phenobarb, sold under the brand name Luminal among others, is a medication of the barbiturate type. [6] It is recommended by the World Health Organization (WHO) for the treatment of certain types of epilepsy in developing countries . [ 8 ] The first study involved 11 dogs administered gabapentin (10 mg/kg t.i.d.) in addition to phenobarbital and potassium bromide.8 A positive response to gabapentin, defined as ≥ 50% reduction in seizure frequency, was reported in six of the 11 dogs. Gabapentin (Neurontin-Pfizer) Is a useful AED because it is excreted renally and does not cause hepatotoxicity. Of unknown efficacy, although a single report suggests it reduces seizure frequency in refractory cases. 8 A 2005 study investigated gabapentin as an add-on anticonvulsant in dogs with refractory seizures and found that in a 4-month period, 3 of 17 dogs were seizure-free and 4 other dogs had a 50% reduction in seizure frequency. Gabapentin is a new antiepileptic drug which is used in humans with complex partial epilepsy. Recently, two published studies described the efficacy of gabapentin in dogs with refractory epilepsy. However, clinical application of gabapentin in dogs with refractory psychomotor seizure has not been documented. The present report describes a 2-year-old male Doberman pinscher dog with a history of
