primidone (cont.)

What should I discuss with my healthcare provider before taking primidone (Mysoline)?

You should not use this medication if you are allergic to primidone or phenobarbital (Luminal, Solfoton), or if you have porphyria.

You may have thoughts about suicide while taking this medication. Tell your doctor if you have new or worsening depression or suicidal thoughts during the first several months of treatment, or whenever your dose is changed.

Your family or other caregivers should also be alert to changes in your mood or symptoms. Your doctor will need to check you at regular visits. Do not miss any scheduled appointments.

Before taking this medication, tell your doctor if you are allergic to any drugs, or if you are pregnant or breast-feeding.

Primidone may cause harm to an unborn baby, but having a seizure during pregnancy could harm both the mother and the baby. Do not start taking primidone during pregnancy without your doctor's advice.

If you become pregnant while taking primidone, do not stop taking it without telling your doctor. Seizure control is very important during pregnancy and the benefits of preventing seizures may outweigh any risks posed by taking primidone.

If you have taken primidone during pregnancy, be sure to tell the doctor who delivers your baby about your primidone use. Both you and the baby may need to receive medications to prevent excessive bleeding during delivery and just after birth.

Primidone can pass into breast milk and may harm a nursing baby. Do not use this medication without telling your doctor if you are breast-feeding a baby.

How should I take primidone (Mysoline)?

Take this medication exactly as it was prescribed for you. Do not take the medication in larger amounts, or take it for longer than recommended by your doctor. Follow the directions on your prescription label.

Primidone is usually taken 2 to 4 times daily. If you are switching to primidone from another seizure medication, you may need to start taking primidone only at bedtime. Follow your doctor's instructions.

If you are taking primidone to treat seizures, keep taking the medication even if you feel fine. You may have an increase in seizures if you stop taking primidone. Follow your doctor's instructions.

To be sure this medication is helping your condition, your blood may need to be tested on a regular basis. Do not miss any scheduled appointments.

Do not change your dose of primidone without your doctor's advice. Tell your doctor if the medication does not seem to work as well in treating your condition.

Carry an ID card or wear a medical alert bracelet stating that you are taking primidone, in case of emergency. Any doctor, dentist, or emergency medical care provider who treats you should know that you are taking a seizure medication.

Store primidone at room temperature away from moisture, light, and heat.
