Phenobarbitone - Dosage and How to Use

How should Phenobarbitone be used?

Phenobarbitone is usually taken 1 to 2 times a day. The doctor may start you or your child on a low dose and then slowly increase the dose. Follow the instructions on the label carefully and ask your pharmacist or doctor if you are unsure.

Do not take this medication more often than directed and do not stop unless instructed by the doctor. Stopping this medicine too rapidly can increase the risk of seizures or fits.

Do not change brands or dosage forms without informing your doctor.

Oral liquid form

  • Shake well before using. Use a medicine spoon or the graduated syringe provided to measure your medicine. Do not use household spoons as they may not be accurate.

Tablet form

  • Swallow the tablets with a glass of water. If you or your child is unable to swallow the tablet, you may crush it and add it to small amount of food (i.e. yogurt, ice-cream, syrup) before administering it. Phenobarbitone can be taken with or without food.

What should I do if I miss a dose?

Administer the dose as soon as you remember and then continue to take it as you normally would. However, if it is almost time for the next dose, skip the missed dose and give the next dose at the usual time.

Do not double or increase the dose.

If you or your child has missed more than two doses or you are not sure of what to do, consult your doctor or pharmacist.

If you or your child has less than two weeks supply of medication, please ensure that you have made an appointment with your neurologist or made arrangements to collect more medication.
