Anti-epileptic medication information


All medications have side effects. Not everyone will experience those side effects and many children tolerate medicines very well.

Some side effects occur when commencing a new medication and are dose-related. Speak to your doctor as an adjustment of dosage may remove the adverse effect. Possible side effects in this category include:

  • upset tummy
  • tiredness or sleepiness
  • occasional poor coordination

Many families worry about learning. There are a number of factors that influence learning, including the epilepsy syndrome, depression, behaviour, and medications. Good documentation of school progress and input from the teacher is helpful for your doctor in determining what might help. Keep a diary of concerns associated with new medicines or dose increases.

Medication management

  • Do not stop giving or change medications without discussing this with your doctor.
  • Do not change the dose of medication without talking to your doctor first.
  • If your child has more seizures than usual, contact your doctor.
  • It is best to make sure your child always has the same brand of medications as there may be differences in the performance across brands.
  • Try to give the medications at approximately the same time each day.
  • Always make sure you have enough medication. Order a new prescription at least 2 weeks before you are due to run out.
  • Always check the expiry date on your medication, if the medication has expired, take it back to your pharmacy.
  • In case of overdose or poisoning please contact the Poisons Information Center on 131126.

What if my child vomits?

  • If your child vomits within 30 minutes after having their dose then repeat the dose.
  • If it is longer than 30 minutes since having the dose you do not need to repeat the dose but if vomiting or diarrhoea continues, seek medical help.

What if I forget to give a dose?

  • If a dose is missed, it should be taken as soon as it is remembered.
  • The next due dose should be taken at the usual time.
  • However, if the missed dose is remembered in close proximity to the next due dose (i.e. within 3 to 4 hours of the next dose), please seek medical advice.
  • If unsure about what to do, the treating GP, epilepsy nurse, paediatrician or neurologist should be contacted.

Medication storage

  • Make sure the medication is kept out of direct sunlight and away from heat.
  • Keep out of reach of children.
  • If you have any concerns please contact your doctor.
