Dilantin (active ingredient: phenytoin) is a prescription medication used to prevent and control certain types of seizures. It belongs to a class of medications called anticonvulsants (also known as antiepileptic medications), which help reduce abnormal electrical activity in the brain.
By helping stabilize nerve activity, Dilantin lowers the risk of seizures and supports long-term seizure control.
Dilantin is used to treat and prevent several types of seizures, including:
It may also be used to prevent seizures after brain (neurosurgical) surgery, when recommended by a healthcare provider.
By reducing seizure activity, Dilantin can help improve safety and quality of life for people living with epilepsy.
Dilantin belongs to a class of medications called anticonvulsants.
It works by:
These actions help reduce the frequency of seizures and improve seizure control.
When used as prescribed, Dilantin may help:
Take Dilantin exactly as prescribed by your healthcare provider. Do not stop taking the medication suddenly unless instructed to do so, as abruptly stopping phenytoin may increase the risk of seizures. Regular follow-up appointments and blood tests may be needed to ensure the medication is working safely and effectively.
Dilantin is available as extended-release capsules and chewable tablets. Take the medication exactly as prescribed by your healthcare provider. Your dosage and how often you take it will depend on your age, the type of seizures being treated, your blood phenytoin levels, and how well you respond to treatment.
Extended-Release Capsules
The extended-release capsules are usually taken once daily or in divided doses, depending on your prescribed treatment plan.
When taking the capsules:
Chewable Tablets
The chewable tablets are typically taken two to three times daily, as directed by your healthcare provider.
The tablets may be:
Taking the medication with food or a meal may help reduce stomach upset.
The appropriate dose of Dilantin varies depending on your age, body weight, blood phenytoin levels, and response to treatment.
Adults
For most adults, the usual starting dosage is:
If needed, your healthcare provider may gradually increase your dose. In some cases, the dosage may be increased to:
Your healthcare provider will adjust your dosage based on seizure control and blood tests that measure phenytoin levels.
Children
For children, the usual starting dosage is:
The maximum recommended starting dose is:
For long-term treatment, the typical maintenance dosage ranges from:
Your child’s healthcare provider will monitor blood phenytoin levels and adjust the dosage as needed to ensure safe and effective seizure control.
Because the appropriate dose of phenytoin varies between individuals, your healthcare provider will monitor your response to treatment and may perform regular blood tests to ensure your medication level remains within the therapeutic range.
Dilantin (Phenytoin Sodium) is available in the following forms and strength:
Before taking Dilantin, tell your healthcare provider about your complete medical history, allergies, and all medications you are taking. Careful monitoring is important to help ensure the medication is safe and effective.
Do not stop taking Dilantin without first consulting your healthcare provider.
Stopping phenytoin suddenly may increase your risk of status epilepticus, a serious and potentially life-threatening seizure emergency. If your treatment needs to be stopped, your healthcare provider will gradually reduce your dose or transition you to another anticonvulsant medication.
If you develop a serious allergic or hypersensitivity reaction, your healthcare provider may switch you more quickly to an anticonvulsant that is not in the hydantoin class.
Like other antiepileptic drugs (AEDs), Dilantin may increase the risk of suicidal thoughts or behavior in some people.
This risk may occur as early as one week after starting treatment. Contact your healthcare provider immediately if you or your family notice:
Regular follow-up appointments allow your healthcare provider to monitor your mental health while you are taking Dilantin.
Do not take Dilantin if you:
Always tell your healthcare provider about all medications you are taking before starting Dilantin.
If you are pregnant, planning to become pregnant, or think you may be pregnant, talk to your healthcare provider before taking Dilantin.
Phenytoin may harm an unborn baby. However, uncontrolled seizures during pregnancy can also pose serious risks to both the mother and the baby.
If you become pregnant while taking Dilantin, do not stop the medication on your own. Your healthcare provider will carefully weigh the benefits of seizure control against the potential risks and determine the safest treatment plan for you.
Dilantin may cause:
Until you know how the medication affects you:
Alcohol and marijuana (cannabis) can worsen these side effects. In addition, alcohol may affect the amount of phenytoin in your bloodstream, making the medication less effective or increasing the risk of side effects. Talk to your healthcare provider if you drink alcohol or use cannabis.
Contact your healthcare provider immediately if you experience:
Regular follow-up appointments and blood tests are important while taking Dilantin. Your healthcare provider may monitor your phenytoin levels to ensure the medication remains safe and effective.
Take Dilantin exactly as prescribed by your healthcare provider. Depending on your treatment plan, it is usually taken once or twice a day, with or without food. Try to take your doses at the same time each day to help maintain consistent medication levels in your body. Do not stop taking Dilantin or change your dose without consulting your healthcare provider, as doing so may increase your risk of seizures.
Dilantin begins working soon after you start taking it, but it takes time for the medication to reach a stable level in your body. For most people, steady-state levels are reached within 7 to 10 days after starting a typical dose. Your healthcare provider may gradually adjust your dosage based on your response and blood phenytoin levels. It may take up to 4 weeks before you experience the full benefits of treatment.
No. Dilantin is not considered an addictive medication and has not been shown to cause dependence or produce a “high.” However, it should only be taken as prescribed by your healthcare provider. Do not stop taking Dilantin suddenly, as abrupt discontinuation can increase the risk of seizures.
