Q: How does Dilantin work?

Mechanism of Action Dilantin belongs to a class of drugs known as anticonvulsants or anti-epileptics. It works by slowing down the electrical impulses in the brain that cause seizures. The medication helps manage seizure activity through the following processes: Stabilizing nerve cells: It targets the motor cortex of the brain, where it helps stabilize the threshold against hyperexcitability. This prevents nerve cells from firing too quickly or repeatedly. Regulating sodium channels: Dilantin works by blocking certain sodium channels in the brain. By limiting the movement of sodium ions across cell membranes, it prevents the excessive electrical discharge that leads to a seizure. Preventing seizure spread: By calming overactive neurons, the medication helps stop abnormal electrical activity from spreading to other parts of the brain.

Q: What are the active ingredients in Dilantin?

The active ingredient in Dilantin is phenytoin .

Q: What are the side effects of Dilantin?

Q: Is Dilantin safe during pregnancy and breastfeeding?

Pregnancy Taking Dilantin during pregnancy may increase the risk of birth defects or other health problems for the baby. However, having a seizure during pregnancy can also be dangerous for both the parent and the baby. It is important to talk with a healthcare provider about the risks and benefits of continuing this medication while pregnant. Dilantin can cause a bleeding disorder in newborns. To help prevent this, healthcare providers may recommend taking Vitamin K during the final weeks of pregnancy and giving Vitamin K to the baby immediately after birth. Do not start or stop taking seizure medication during pregnancy without medical advice. Stopping the medication suddenly can cause severe, long-lasting seizures that could harm the pregnancy. Breastfeeding Dilantin passes into breast milk. Because of the potential for side effects in the nursing infant, breastfeeding while taking this medication is generally not recommended. Individuals should discuss their options with a healthcare provider to determine the safest approach for their situation.

Q: What forms and strengths does Dilantin come in?

Oral Dosage Forms Dilantin is provided in the following oral formulations: Extended-release capsules: These are phenytoin sodium capsules designed to release the medication slowly into the body. Chewable tablets: These are phenytoin tablets that can be chewed or swallowed whole. Oral suspension: This is a liquid form of phenytoin that must be shaken thoroughly before each dose is measured. Injectable Form Dilantin is also available as an injectable solution (phenytoin sodium). This form is typically administered by a healthcare professional in a hospital or clinical setting, often for the treatment of severe or continuous seizures, or when oral administration is not possible.

Q: What is the FDA approval status of Dilantin?

FDA Approval and Indications Dilantin is approved by the U.S. Food and Drug Administration (FDA) to treat generalized tonic-clonic (grand mal) seizures and complex partial seizures. It is also indicated for the prevention and treatment of seizures that may occur during or after neurosurgery. Boxed Warning The FDA requires a boxed warning for phenytoin injection due to the risk of severe cardiovascular events. If the medication is administered too rapidly via an intravenous (IV) line, it can lead to dangerously low blood pressure and life-threatening heart rhythm changes. Because of these risks, the rate of infusion must be strictly limited, and patients require continuous cardiac monitoring during administration. Prescription Status Dilantin is a prescription-only medication. It is available in various formulations, including extended-release capsules, oral suspensions, and injectable solutions, to meet different clinical needs.

How to Take Dilantin

Dilantin is typically taken by mouth as a capsule, chewable tablet, or liquid suspension. It is important to take this medication exactly as prescribed and at the same time each day to maintain a steady level in the blood. Do not change the dose or stop taking the medication without consulting a healthcare provider, as stopping abruptly can increase the risk of seizures.

Oral Administration

Extended-release capsules: These should be swallowed whole. Do not crush, chew, or open them.
Chewable tablets: These must be chewed thoroughly before swallowing.
Oral suspension (liquid): Shake the bottle well before each use. Use a medical measuring device, such as an oral syringe or dose-measuring cup, rather than a household spoon to ensure the dose is accurate.

Dilantin can be taken with or without food. However, it is important to be consistent in how you take it. If the medication causes stomach upset, taking it with food or milk may help.

Missed Doses

If a dose is missed, it should be taken as soon as it is remembered. If it is almost time for the next scheduled dose, skip the missed dose and continue with the regular schedule. Do not take two doses at once to make up for a missed one.

Injection

The injectable form of this medication is administered by a healthcare professional into a vein or muscle, usually in a hospital or clinical setting where the patient can be monitored closely.

Medical Supervision: Always follow a doctor's specific instructions for lowering the dose.
Side Effects: Even if you experience side effects or mood changes, do not stop the medication until you have spoken with a healthcare provider.
Consistency: Maintain your regular dosing schedule until your doctor advises otherwise to ensure seizure control remains stable.
