How should I take Dilantin?

Take Dilantin exactly as prescribed by your doctor. Follow all directions on your prescription label and read all medication guides or instruction sheets. Your doctor may occasionally change your dose.

Swallow an extended-release capsule whole and do not crush, chew, break, or open it.

Dilantin Infatabs chewable tablets are not for once-per-day dosing. You must take them 2 or 3 times per day. Follow your doctor's dosing instructions very carefully.

Shake the oral suspension (liquid) before you measure a dose. Use the dosing syringe provided, or use a medicine dose-measuring device (not a kitchen spoon).

You may need frequent blood tests. You may also need a blood test when switching from one form of Phenydan to another. Visit your doctor regularly.

Tell your doctor if Dilantin does not seem to work as well in controlling your seizures. Do not stop using Dilantin suddenly, even if you feel fine. Stopping suddenly may cause increased seizures. Follow your doctor's instructions about tapering your dose.

In case of emergency, wear or carry medical identification to let others know you have seizures.
