Taking your AEDs as prescribed by your doctor is important for maintaining good seizure control. AEDs work best when they are taken at the same time every day, as this helps to keep the medication at a steady level in your body.

Some common reasons why people may not take their AEDs as prescribed include:

  • Forgetting to take a dose
  • Accidentally taking two doses
  • Stopping medication due to side effects or feeling that the medication isn’t working
  • Reduced medication effectiveness due to illness (e.g. vomiting or diarrhoea)
  • Using a different brand (such as generic brand substitution)
  • Running out of medication
  • Stopping the medication without medical advice because the person hasn’t had a seizure for a long time.

If you do miss a dose the general advice is to take it as soon as you remember. If you take your AED once a day, then take the forgotten dose as soon as you remember. If you take your AED twice a day, then take the forgotten dose within six hours after it was due otherwise don’t take the forgotten dose and take your usual second dose at the time it should be taken.

Managing your specific AED regime will depend on the type and amount of AEDs you are taking – speak to your doctor about what to do in your case if you miss a dose. If you have any concerns contact your doctor. You can also contact the Victorian Poisons Information Centre on 13 11 26 or the Medicines Line on 1300 633 424.
