Phenytoin Overview Phenytoin is an antiepileptic agent which is effective for tonic-clonic and focal seizures 1. It has a narrow therapeutic index and the relationship between dose and serum phenytoin. Gradually decrease phenytoin dosage by up to 50 when used concomitantly with cenobamate.
Cenobamate will increase the level or effect of phenytoin by affecting hepatic enzyme CYP2C19 metabolism. Consider a dose reduction of CYP2C19 substrates as clinically appropriate when used concomitantly with cenobamate. Phenytoin is a hydantoin derivative and a non-sedative antiepileptic agent with anticonvulsant activity.
Phenytoin potentially acts by promoting sodium efflux from neurons located in the motor cortex reducing post-tetanic potentiation at synapses. The reduction of potentiation prevents cortical seizure foci spreading to adjacent areas stabilizing the threshold against hyperexcitability. Before the initiation of treatment with phenytoin in a woman of childbearing potential pregnancy testing should be considered.
Due to enzyme induction Phenytoin Injection may result in a failure of the therapeutic effect of hormonal contraceptives see Sections 45 and 46.

Suicidal behavior and ideation have been observed as early as one week after starting treatment with lacosamide and is an adverse reaction from use of most AEDs.
In clinical trials with a medial treatment duration of 12 weeks the incidence of suicidal ideation. A typical loading regimen of amiodarone would be to use large oral doses for a week or two then taper the dosage over the next month or so. It is not unusual to give people 800 or 1200 milligrams mg per day at first and then eventually to maintain them on as little as 100 or 200 mg per day orally.
