Dilantin

Hyperglycemia (high blood sugar) may occur in people taking Dilantin, which blocks the release of insulin. People with diabetes may experience increased blood sugar levels due to Dilantin.

Abnormal softening of the bones may occur in people taking Dilantin because of Dilantin's interference with vitamin D metabolism.

Special information if you are pregnant or breastfeeding

If you are pregnant or plan to become pregnant, inform your doctor immediately. Because of the possibility of birth defects with antiepileptic drugs such as Dilantin, you may need to discontinue the drug. Do not, however, stop taking it without first consulting your doctor. Dilantin appears in breast milk; breastfeeding is not recommended during treatment with this drug.

Recommended dosage

Dosage is tailored to each individual's needs. Your doctor will monitor blood levels of the drug closely, particularly when switching you from one drug to another.

ADULTS

Standard Daily Dosage

If you have not had any previous treatment, your doctor will have you take one 100-milligram Dilantin capsule 3 times daily to start.

On a continuing basis, most adults need 1 capsule 3 to 4 times a day. Your doctor may increase that dosage to 2 capsules 3 times a day, if necessary.

Once-A-Day Dosage

If your seizures are controlled on 100-milligram Dilantin capsules 3 times daily, your doctor may allow you to take the entire 300 milligrams as a single dose once daily.

CHILDREN

The starting dose is 5 milligrams per 2.2 pounds of body weight per day, divided into 2 or 3 equal doses; the most a child should take is 300 milligrams a day. The regular daily dosage is usually 4 to 8 milligrams per 2.2 pounds. Children over 6 years of age and adolescents may need the minimum adult dose (300 milligrams per day).

Overdosage

An overdose of Dilantin can be fatal. If you suspect an overdose, seek medical attention immediately.

• Symptoms of Dilantin overdose may include:
  Coma, difficulty in pronouncing words correctly, involuntary eye movement, lack of muscle coordination, low blood pressure, nausea, sluggishness, slurred speech, tremors, vomiting
