Do not stop taking Phenobarbital until you have seen your doctor as it is important to control your fits.

Use of Phenobarbital during pregnancy may lead to drug dependence and sleepiness in the newborn baby. However, your doctor may decide that it is very important that you continue to take Phenobarbital. He or she will explain the risks to you.

Adequate supplements of folic acid should be taken before conception and during pregnancy.

As Phenobarbital is released into breast milk this may make your baby sleepy or get too little oxygen and therefore breast feeding is not advisable.
