Epanutin / Dilantin  (phenytoin) is an anticonvulsant medication that can reduce the frequency and intensity of epileptic seizures. Phenytoin works to prevent excessive electrical activity in the brain by preventing sodium from entering nerve cells when they begin to fire rapid and repetitive electrical signals.

In normal nerve signalling, some build up of sodium in the junctions of nerve cells is necessary for the electrical signal to be passed on to other nerve cells. Excessive levels of sodium can cause spikes in electrical activity and trigger a seizure. Phenytoin can prevent this build-up, so it helps to stabilize electrical activity in the brain. It is not a cure for epilepsy, and only reduces the frequency and intensity of seizures.

Dosage

Take the medication exactly as prescribed. Do not stop taking Epanutin abruptly without consulting the doctor. Abrupt discontinuation of Epanutin may result in an increased incidence of seizures or a seizure attack that does not stop (status epilepticus).

The dosage and regimen can only be set by a doctor. Try to take the medicine at the same time each day. If a dose is forgotten, take it as soon as this is realized, as long as it is on the same day. Do not double-dose to make up for a missed dose.

Avoid taking Epanutin at the same time as antacids such as calcium carbonate, aluminum hydroxide, or magnesium hydroxide (Mylanta, Gelusil, Calci-Chew, etc.)

A woman of childbearing age should use effective contraceptives while using Epanutin. A fetus is at risk of severe congenital defects, and the level of phenytoin may decrease in a woman who becomes pregnant during treatment with Epanutin, increasing the risk of seizures.
