Treatment of patients with absence seizures only is mainly with valproic acid or ethosuximide, which are of equal efficacy controlling absences in around 75% of patients. Lamotrigine monotherapy is less effective, with nearly half of the patients becoming seizure free. This view has been recently confirmed by Glauser et al. (2010), who studied the effects of ethosuximide, valproic acid, and lamotrigine in children with newly diagnosed childhood absence epilepsy. Drug dosages were incrementally increased until the child was free of seizures, the maximal allowable dose was reached, or a criterion indicating treatment failure was met. The primary outcome was freedom from treatment failure after 16 weeks of therapy; the secondary outcome was attentional dysfunction. After 16 weeks of therapy, the freedom-from-failure rates for ethosuximide and valproic acid were similar and were higher than the rate for lamotrigine. There were no significant differences between the three drugs with regard to discontinuation because of adverse events. Attentional dysfunction was more common with valproic acid than with ethosuximide.

If monotherapy fails or unacceptable adverse reactions appear, replacement of one by another of the three antiepileptic drugs is the alternative. Adding small doses of lamotrigine to sodium valproate may be the best combination in resistant cases.

While ethosuximide is effective in treating only absence seizures, valproic acid is effective in treating multiple seizure types including tonic-clonic seizure and partial seizure, as such it may be a better choice if a patient is exhibiting multiple types of seizures.

Similarly, lamotrigine treats multiple seizure types including partial seizures and generalized seizures, therefore it is also an option for patients with multiple seizure types. Clonazepam (Klonopin, Rivotril) is effective in the short term but is not generally recommended for treatment of absence seizure because of the rapid development of tolerance and high frequency of side effects.

Carbamazepine, vigabatrin, and tiagabine are contraindicated in the treatment of absence seizures, irrespective of cause and severity. This is based on clinical and experimental evidence. In particular, the GABA agonists vigabatrin and tiagabine are used to induce, not to treat, absence seizures and absence status epilepticus. Similarly, oxcarbazepine, phenytoin, phenobarbital, gabapentin, and pregabalin should not be used in the treatment of absence seizures because these medications may worsen absence seizures.

Lorazepam and clonazepam are front line treatment for severe convulsions, belonging to the benzodiazepine class of medications.

The first line treatment of choice for someone who is actively seizing is a benzodiazepine, most guidelines recommend lorazepam. This may be repeated if there is no effect after 10 minutes. If there is no effect after two doses, barbiturates or propofol may be used. Benzodiazepines given by a non-intravenous route appear to be better than those given by intravenous as the intravenous takes time to start.

Ongoing anti-epileptic medications are not typically recommended after a first seizure except in those with structural lesions in the brain. They are generally recommended after a second one has occurred. Approximately 70% of people can obtain full control with continuous use of medication. Typically one type of anticonvulsant is preferred. Following a first seizure, while immediate treatment with an anti-seizure drug lowers the probability of seizure recurrence up to five years it does not change the risk of death and there are potential side effects.

In seizures related to toxins, up to two doses of benzodiazepines should be used. If this is not effective pyridoxine is recommended. Phenytoin should generally not be used.

There is a lack of evidence for preventative anti-epileptic medications in the management of seizures related to intracranial venous thrombosis.

Anticonvulsants are the most successful medication in reducing and preventing seizures from reoccurring. The goal of these medications in being able to reduce the reoccurrence of seizures is to be able to limit the amount of rapid and extensive firing of neurons so that a focal region of neurons cannot become over-activated thereby initiating a seizure. Although anticonvulsants are able to reduce the amount of seizures that occur in the brain, no medication has been discovered to date that is able to prevent the development of epilepsy following a head injury. There are a wide range of anticonvulsants that have both different modes of action and different abilities in preventing certain types of seizures. Some of the anticonvulsants that are prescribed to patients today include: Carbamazepine (Tegretol), Phenytoin (Dilantin Kapseals), Gabapentin (Neurontin), Levetiracetam (Keppra), Lamotrigine (Lamictal), Topiramate (Topamax), Tiagabine (Gabitril), Zonisamide (Zonegran) and Pregabalin (Lyrica).

The trigger needs to be identified before prescribing anti-epileptics. The most commonly prescribed drugs for reflex epilepsy are valproate, carbamazepine and clonazepam, though lamotrigine, levetiracetam are promising.

Avoidance therapy consists of minimizing or eliminating triggers. For example, in those who are sensitive to light, using a small television, avoiding video games, or wearing dark glasses may be useful. Operant-based biofeedback based on the EEG waves has some support in those who do not respond to medications. Psychological methods should not, however, be used to replace medications. Some dogs, commonly referred to as seizure dogs, may help during or after a seizure. It is not clear if dogs have the ability to predict seizures before they occur.

Any number of medications may be used to both prevent and treat seizures.

Generally after three medications are tried, different treatment should be considered. It should also be noted that some medications are harmful to those with this syndrome and can increase seizures.

Seven anti-epileptic drugs are approved for use in cases of suspected primary generalized epilepsy:

- Felbamate

- Levetiracetam

- Zonisamide

- Topiramate

- Valproate

- Lamotrigine

- Perampanel

Valproate, a relatively old drug, is often considered the first-line treatment. It is highly effective, but its association with fetal malformations when taken in pregnancy limits its use in young women.

All anti-epileptic drugs (including the above) can be used in cases of partial seizures.

Alternative medicine, including acupuncture, psychological interventions, routine vitamins, and yoga, have no reliable evidence to support their use in epilepsy. There is not enough evidence to support the use of cannabis. Melatonin, as of 2016, is insufficiently supported by evidence. The trials were of poor methodological quality and it was not possible to draw any definitive conclusions.

Many anticonvulsant oral medications are available for the management of temporal lobe seizures. Most anticonvulsants function by decreasing the excitation of neurons, for example, by blocking fast or slow sodium channels or by modulating calcium channels; or by enhancing the inhibition of neurons, for example by potentiating the effects of inhibitory neurotransmitters like GABA.

In TLE, the most commonly used older medications are phenytoin, carbamazepine, primidone, valproate, and phenobarbital. Newer drugs, such as gabapentin, topiramate, levetiracetam, lamotrigine, pregabalin, tiagabine, lacosamide, and zonisamide promise similar effectiveness, with possibly fewer side-effects. Felbamate and vigabatrin are newer, but can have serious adverse effects so they are not considered as first-line treatments.

Up to one third of patients with medial temporal lobe epilepsy will not have adequate seizure control with medication alone. For patients with medial TLE whose seizures remain uncontrolled after trials of several types of anticonvulsants (that is, the epilepsy is "intractable"), surgical excision of the affected temporal lobe may be considered.

Patients with ICOE-G need prophylactic treatment mainly with carbamazepine or other antiepileptic drugs licensed for focal seizures. A slow reduction in the dose of medication 2 or 3 years after the last visual or other minor or major seizure should be advised, but if visual seizures reappear, treatment should be restored.

The ketogenic diet mimics some of the effects of starvation, in which the body first uses up glucose and glycogen before burning stored body fat. In the absence of glucose, the body produces ketones, a chemical by-product of fat metabolism that has been known to inhibit seizures.

A modified version of a popular low-carbohydrate, high-fat diet which is less restrictive than the ketogenic diet.

The low glycemic index treatment (LGIT) is a new dietary therapy currently being studied to treat epilepsy. LGIT attempts to reproduce the positive effects of the ketogenic diet. The treatment allows a more generous intake of carbohydrates than the ketogenic diet, but is restricted to foods that have a low glycemic index, meaning foods that have a relatively low impact on blood-glucose levels.

These foods include meats, cheeses, and most vegetables because these foods have a relatively low glycemic index. Foods do not have to be weighed, but instead careful attention must be paid to portion size and balancing the intake of carbohydrates throughout the day with adequate amounts of fats and proteins.

Valproate is available to be given intravenously, and may be used for status epilepticus. Carbamazepine is not available in an intravenous formulation, and does not play a role in status epilepticus.

Phenytoin was once another first-line therapy, although the prodrug fosphenytoin can be administered three times as fast and with far fewer injection site reactions. If these or any other hydantoin derivatives are used, then cardiac monitoring is a must if they are administered intravenously. Because the hydantoins take 15–30 minutes to work, a benzodiazepine or barbiturate is often coadministered. Because of diazepam's short duration of action, they were often administered together anyway.

Many antiepileptic drugs are used for the management of canine epilepsy. Oral phenobarbital, in particular, and imepitoin are considered to be the most effective antiepileptic drugs and usually used as ‘first line’ treatment. Other anti-epileptics such as zonisamide, primidone, gabapentin, pregabalin, sodium valproate, felbamate and topiramate may also be effective and used in various combinations. A crucial part of the treatment of pets with epilepsy is owner education to ensure compliance and successful management.

Where surgery is not recommended, further management options include new (including experimental) anticonvulsants, and vagus nerve stimulation. The ketogenic diet is also recommended for children, and some adults. Other options include brain cortex responsive neural stimulators, deep brain stimulation, stereotactic radiosurgery, such as the gamma knife, and laser ablation.

No high quality evidence has shown any drug very useful as of 2013. Rufinamide, lamotrigine, topiramate and felbamate may be useful.

Given the benign nature of the condition and the low seizure frequency, treatment is often unnecessary. If treatment is warranted or preferred by the child and his or her family, antiepileptic drugs can usually control the seizures easily. Carbamazepine is the most frequently used first-line drug, but many other antiepileptic drugs, including valproate, phenytoin, gabapentin, levetiracetam and sultiame have been found effective as well. Bedtime dosing is advised by some. Treatment can be short and drugs can almost certainly be discontinued after two years without seizures and with normal EEG findings, perhaps even earlier.

Parental education about Rolandic epilepsy is the cornerstone of correct management. The traumatizing, sometimes long-lasting effect on parents is significant.

It is unclear if there are any benefits to clobazam over other seizure medications.

LGS seizures are often treatment resistant, but this does not mean that treatment is futile. Options include anticonvulsants, anesthetics, steroids such as prednisone, immunoglobulins, and various other pharmacological agents that have been reported to work in individual patients.

Gelastic seizures are usually not responsive to pharmacotherapy. They can produce secondary seizure characteristics which may respond to medications or surgery. These options are not a guaranteed cure, and depend primarily on the individual patient’s pathology.

The treatment depends on the cause of the seizures. If the seizures are caused by a tumor, surgical removal can be attempted. However, surgical removal is not always an immediate cure, and there can be complications. Complications can include cerebral infarcts, and cognitive deterioration. Hormonal treatment can be attempted to help individuals with precocious puberty. Anti-epileptic drugs could be an option as well depending on the patient’s criteria. These drugs could include carbamazepine, clobazam, lamotrigine, levetiracetam, oxcarbazepine and topiramate. However, usually none of these medications are capable of stopping the seizures from occurring, and like any medication, there may be undesirable side effects. There is also a specialized form of radiotherapy that may be an option depending on the tumor type and location. Once again, there are very few areas in the world that offer this treatment. Gamma knife radiosurgery can be the treatment of choice when it comes to hypothalamic hamartomas. It is a low risk option due to its lower frequency of neurological deficits. It is recommended for patients with tumors that don’t come into contact with the optic chiasm.

Helmets may be used to provide protection to the head during a seizure. Some claim that seizure response dogs, a form of service dog, can predict seizures. Evidence for this, however, is poor. At present there is not enough evidence to support the use of cannabis for the management of seizures, although this is an ongoing area of research. There is tentative evidence that a ketogenic diet may help in those who have epilepsy and is reasonable in those who do not improve following typical treatments.

Continuous prophylactic antiepileptic drug (AED) treatment may not be needed particularly for children with only 1-2 or brief seizures. This is probably best reserved for children whose seizures are unusually frequent, prolonged, distressing, or otherwise significantly interfering with the child’s life. There is no evidence of superiority of monotherapy with any particular common AED.

Autonomic status epilepticus in the acute stage needs thorough evaluation for proper diagnosis and assessment of the neurologic/autonomic state of the child. "Rescue" benzodiazepines are commonly used to terminate it. Aggressive treatment should be avoided because of the risk of iatrogenic complications, including cardiovascular arrest. There is some concern that intravenous lorazepam and/or diazepam may precipitate cardiovascular arrest. Early parental treatment is more effective than late emergency treatment. Buccal midazolam is probably the first choice medication for out of hospital termination of autonomic status epilepticus which should be administered as soon as the child shows evidence of onset of its habitual autonomic seizures.

Parental education about Panayiotopoulos syndrome is the cornerstone of correct management. The traumatizing, sometimes long-lasting effect on parents is significant particularly because autonomic seizures may last for many hours compounded by physicians’ uncertainty regarding diagnosis, management, and prognosis.

Seizures in Dravet syndrome can be difficult to manage but may be reduced by anticonvulsant medications such as clobazam, stiripentol, topiramate and valproate. Because the course of the disorder varies from individual to individual, treatment protocols may vary. A diet high in fats and low in carbohydrates may also be beneficial, known as a ketogenic diet. Although diet adjustment can help, it does not eliminate the symptoms. Until a better form of treatment or cure is discovered, those with this disease will have myoclonic epilepsy for the rest of their lives.

Certain anticonvulsant drugs that are classed as Sodium Channel Blockers are now known to make seizures worse in most Dravet patients. These drugs include carbamazepine, gabapentin, lamotrigine, and phenytoin.

Treatments include cognitive rehabilitation through psychomotor and speech therapy. In addition, valproate is often administered to prevent recurrence of febrile seizures and benzodiazapine is used for long lasting seizures, but these treatments are usually insufficient.

Stiripentol was the only drug for which a double-blind placebo trial was performed and this drug showed efficacy in trials. It acts as a GABAergic agent and as a positive allosteric modulator of GABA receptor. Stiripentol, can improve focal refractory epilepsy, as well as Dravet's syndrome, supplemented with clobazam and valproate was approved in Europe in 2007 as a therapy for Dravet syndrome and has been found to reduce overall seizure rate by 70%. In cases with more drug resistant seizures, topiramate and the ketogenic diet are used as alternative treatments.

Cannabidiol (CBD) has received orphan drug status in the United States, for treatment of Dravet syndrome which will allow it to be studied.

A modified Atkins diet describes the long term practice of the first phase of the popular Atkins diet the so-called induction phase to reduce seizures through ketosis. In this diet the fat content of the nutrition is slightly lower than in the ketogenic diet at around 60%, the protein content is around 30% and the carbohydrate content is around 10% rendering the diet less restrictive and more compatible with the daily life compared to the ketogenic diet. Several studies show that the modified Atkins diet produces a similar or slightly lower seizure reduction to the ketogenic diet. Some physicians, especially in the USA, recommend the modified Atkins diet because they assume that patients will adhere to it on the long-term because it is more compatible with daily life and the meals are more enjoyable. It has also been concluded in another study that the diet is well tolerated and effective in hard to treat childhood epilepsy.
