a blood cell disorder (such as anemia, hemophilia, and others).

Some people have thoughts about suicide while taking an anticonvulsant. Your doctor will need to check your progress at regular visits while you are taking Peganone. Your family or other caregivers should also be alert to changes in your mood or symptoms.
FDA pregnancy category D. Do not start or stop taking Peganone during pregnancy without your doctor's advice. Seizure control is very important during pregnancy. This medicine may cause harm to an unborn baby, but having a seizure during pregnancy could harm both mother and baby. Tell your doctor right away if you become pregnant while taking this medicine for seizures.
There may be other seizure medicines that can be more safely used during pregnancy. Follow your doctor's instructions about taking this medicine while you are pregnant.
If you are pregnant, your name may be listed on a pregnancy registry. This is to track the outcome of the pregnancy and to evaluate any effects of ethotoin on the baby.
If you have taken Peganone during pregnancy, be sure to tell the doctor who delivers your baby about your this medicine use. Both you and the baby may need to receive medicine to prevent excessive bleeding during delivery and just after birth.
Ethotoin can pass into breast milk and may harm a nursing baby. You should not breast-feed while using this medicine.
How should I take Peganone?
Follow all directions on your prescription label. Your doctor may occasionally change your dose to make sure you get the best results. Do not take this medicine in larger or smaller amounts or for longer than recommended.
If you switch to Peganone from taking another anti-epileptic medicine, do not stop taking the other medicine without your doctor's advice. Carefully follow your doctor's instructions about timing and dosage when switching from one seizure medicine to another.
Seizures are sometimes treated with a combination of drugs. Use all medicines as directed by your doctor. Read the medication guide or patient instructions provided with each medicine. Do not change your doses or medication schedule without your doctor's advice.
Take Peganone after eating. Take your doses at regular intervals to keep a steady amount of the drug in your body at all times.
If a child is taking this medicine, tell your doctor if the child has any changes in weight. Peganone doses are based on weight in children.
Peganone can lower blood cells that help your body fight infections and help your blood to clot. You may get an infection or bleed more easily. Call your doctor if you have unusual bruising or bleeding, or signs of infection (fever, chills, sore throat).
While using Peganone, you may need frequent blood and urine tests.
Do not stop using Peganone suddenly, even if you feel fine. Stopping suddenly may cause increased seizures. Follow your doctor's instructions about tapering your dose.
Wear a medical alert tag or carry an ID card stating that you take Peganone. Any medical care provider who treats you should know that you take seizure medicine.
Store at room temperature away from moisture, heat, and light. Keep the bottle tightly closed when not in use.
