Your medicines, explained

Know about medicines

Find a medicine by its usual name or brand. Learn what to ask, and where to read the official consumer leaflet.

A CMI is the medicine leaflet written for patients. Check the brand and strength on your box. Your pharmacist can help find the right leaflet. Do not stop or change treatment on your own; seek urgent advice for a severe reaction. The named-product directory covers selected products with matched official leaflets; the broader comparison reference includes additional ingredients and rescue medicines, so entry counts differ. These are short educational summaries, not complete product leaflets. Brand examples help identification and do not imply availability or interchangeability.

MedicineWise — use treatment confidentlyThe best antiseizure medicine is the one that suits the person’s epilepsy and circumstances, controls seizures and has acceptable adverse effects. Levetiracetam is a useful option for many people; the important question is whether any medicine is appropriate for the individual rather than routinely favoured or routinely avoided.

Questions you may have

Are Keppra and levetiracetam the same medicine name?

Levetiracetam is the ingredient; Keppra is a brand example. Match the brand, formulation and strength on the pack to its official Australian PI or CMI. Do not change or stop treatment independently.

What should I do about a missed dose?

Ask your pharmacist or prescriber for instructions for your exact medicine, formulation and schedule. Keep that advice with your medicine list. Avoid improvising a catch-up dose or changing subsequent doses yourself.

Epilepsy Action Australia · medication management (2026) ↗

What if vomiting or illness disrupts my medicine?

Ask for advice if you cannot take or keep down your usual treatment. The response depends on the medicine and circumstances. A written illness plan is useful when this has happened before.

Epilepsy Action Australia · medication management (2026) ↗

What should I include in my medicine list?

Include the ingredient, brand, strength, prescribed schedule and reason for each medicine. Add non-prescription products, supplements, allergies and previous reactions. Take the list to medical and pharmacy appointments.

What should I ask if a brand or tablet appearance changes?

Check the ingredient, strength, formulation and directions with your pharmacist. Ask whether any change matters for your treatment plan before assuming two differently labelled products are interchangeable.

Is levetiracetam a bad medicine?

No. It is a useful treatment for appropriate seizure types. Ask why it was chosen for you and report troublesome effects. Thoughtful prescribing means an individual reason and review plan, not avoiding one medicine for everyone.

Know why this medicine was selected

Ask which seizure type or epilepsy syndrome the medicine is intended to treat. Other considerations include age, reproductive plans, other conditions, interactions and previous response. A medicine comparison helps structure the conversation, but a list of advantages cannot predict how you personally will respond.

  • Write the reason for choosing it and the agreed treatment goal.
  • Ask when benefits and tolerability will be reviewed.

Build a reliable medicine record

Record the active ingredient, brand if relevant, strength, formulation, prescribed times and prescriber. Include non-epilepsy medicines, supplements and allergies. A photograph can help identify packaging, but a photograph alone is not a verified current prescription. Check changes with the pharmacist before updating your list.

  • Use the pharmacy label and your current prescription as the starting point.
  • Bring one up-to-date list to every clinician and pharmacy.
  • Record who confirmed a change and the date.

Supporting source ↗ · Supporting source ↗

Missed doses, vomiting and supply gaps

Ask in advance for instructions specific to each medicine. What to do depends on the formulation, timing and clinical situation; do not use one generic rule for all drugs. Do not double a dose unless your clinician’s medicine-specific plan expressly directs that action. If you cannot retain medicines or are running out, contact your pharmacist or treating team promptly.

  • Agree a refill reminder before the supply becomes urgent.
  • Use a checked organiser or routine if helpful.
  • Ask whether storage, crushing or swallowing changes are safe for that formulation.

Supporting source ↗ · Supporting source ↗ · Supporting source ↗

Track benefit and side effects together

A useful review looks at both seizures and everyday function. Keep a short record of sleepiness, balance, concentration, mood or other problems and when they started. Do not assume that every new symptom is caused by medicine, or dismiss a symptom simply because it is not common.

  • Record start dates and prescribed changes beside symptoms.
  • Describe the effect on work, study, relationships or sleep.
  • Contact the prescriber for persistent or troublesome adverse effects.

Supporting source ↗ · Supporting source ↗

Know the urgent warning instructions

Read the serious adverse-effect section of your exact medicine leaflet and ask the pharmacist to explain it. Severe allergy symptoms, collapse, major breathing difficulty or rapidly worsening illness need emergency assessment. A new rash, particularly with fever, blisters or mouth/eye involvement, needs urgent medical advice.

  • For a medical emergency in Australia call 000.
  • Take the medicine list or packaging with you.
  • Obtain urgent clinician instructions about further doses when a serious reaction is suspected.

Interactions, contraception and pregnancy

Check with a pharmacist before adding or stopping any prescription, over-the-counter or complementary product. Some antiseizure medicines affect contraception, and hormonal treatment can affect some antiseizure medicine levels. Pregnancy planning needs a specific medicine review; stopping treatment abruptly after a positive pregnancy test can create serious risk.

  • Tell every prescriber you take antiseizure medicine.
  • Ask about reproductive plans even if pregnancy is not imminent.
  • Keep pregnancy advice medicine-specific rather than relying on a category letter alone.

TGA · pregnancy precautions ↗ · Supporting source ↗ · Supporting source ↗ · Supporting source ↗

When control is incomplete

A breakthrough event should prompt review of what happened, whether it was epileptic, the medicine taken, interactions, adherence barriers and the treatment plan. Persisting seizures are not a personal failure. Ask whether an epilepsy specialist review or additional assessment could clarify the next options.

  • Report new seizure types and injuries.
  • Discuss affordability, supply or side-effect barriers openly.
  • Do not add leftover medicines or borrow another person’s treatment.

Supporting source ↗ · Supporting source ↗ · Supporting source ↗

Changing or stopping treatment needs a plan

Being seizure-free does not mean medicine can automatically stop. Discuss recurrence risk, the epilepsy syndrome, driving implications and personal priorities with the prescriber. If a change is agreed, obtain a written schedule, instructions for recurrence, and a follow-up date. Do not improvise a taper or restart an old schedule.

  • Ask what should happen if symptoms recur.
  • Check whether work, travel or conception plans affect timing.
  • Make sure all clinicians and the pharmacist have the final regimen.

What comparative medicine trials actually tell us

SANAD II supports lamotrigine as an important first-line option for newly diagnosed focal epilepsy, but it does not show that another drug cannot be the right choice for an individual. In generalised and unclassifiable epilepsy, valproate performed better than levetiracetam on important trial outcomes; its reproductive risks can change the choice substantially. Childhood absence epilepsy has a different evidence base. There is no single best medicine for everyone.

SANAD II · focal epilepsy trial ↗ · SANAD II · generalised / unclassified epilepsy trial ↗ · Supporting source ↗

After two unsuccessful appropriate medicine schedules

Ask whether the working definition of drug-resistant epilepsy applies and whether a specialist centre should reassess your options. Check whether previous medicines were appropriate, tolerated and adequately tried, and whether all current events are epileptic. Access barriers and difficulty taking treatment deserve help rather than blame.

Supporting source ↗ · Supporting source ↗

Diet and prescription cannabidiol are specialist treatments

A ketogenic dietary therapy may help selected people, with stronger trial evidence in children than adults. It requires nutritional supervision and monitoring. Purified prescription cannabidiol has trial evidence in particular severe syndromes; that evidence does not establish benefit from every cannabis product or for every epilepsy. Ask about interactions, adverse effects and local approval.

Supporting source ↗ · Supporting source ↗

Reproductive planning includes all relevant partners

Check contraception interactions and discuss pregnancy plans before making treatment changes. Australian valproate advice includes established risks from exposure during pregnancy and a less certain possible paternal-exposure signal. Ask the prescriber what the current advice means for your situation. Do not stop treatment to manage these risks without an agreed alternative plan.

Supporting source ↗ · Supporting source ↗

Use the exact product information

The active ingredient, formulation, strength and other medicines all affect safe use.

PregnancyWise — planning, pregnancy and parenthoodMost people with epilepsy can have a healthy pregnancy. A written plan before conception, shared by your epilepsy and maternity teams, helps balance seizure control, medicine effects and your own priorities. If you are already pregnant, keep taking your prescribed medicine and arrange a prompt review.

Questions you may have

When should pregnancy planning begin?

Arrange specialist review before pregnancy when possible. Discuss seizure control, medicine choices, contraception, folic acid and monitoring. If already pregnant, contact your care team promptly and do not stop treatment on your own.

TGA · pregnancy precautions ↗

What should my plan cover after birth?

Ask for written instructions about medicine monitoring, any planned dose changes, feeding, sleep and practical support. A pregnancy-related dose change needs a postnatal review plan too.

AAN / AES / SMFM · reproductive guideline (2024) ↗

Do men taking valproate need family-planning advice?

Yes. Discuss plans for a family with the prescribing specialist. Australian advice includes precautionary counselling about a possible paternal-exposure risk; uncertainty remains. Do not stop or switch treatment without an individual plan.

Start before trying for a baby

Book a planning appointment rather than waiting for the first positive pregnancy test. Bring your seizure history, previous medicine trials, a complete medicine list and any questions about inherited conditions. A review can confirm the epilepsy diagnosis and discuss whether a treatment adjustment is worthwhile before conception.

  • Ask who will coordinate your neurologist, GP and maternity care.
  • Write down your conception plans and the next review date.
  • If treatment changes, ask when it is appropriate to start trying.

Supporting source ↗ · Supporting source ↗

Understand medicine choices without stopping treatment

The aim is effective seizure protection with the most suitable reproductive safety profile for your epilepsy. Lamotrigine, levetiracetam or oxcarbazepine may be appropriate options for some people. Valproate carries important pregnancy and developmental risks; alternatives should be considered when clinically feasible. A medicine that works well for one epilepsy type may be unsuitable for another.

  • Never stop, reduce or swap an antiseizure medicine yourself when pregnancy is suspected.
  • Ask for a comparison using your seizure type, previous response and reproductive goals.
  • A lower published risk does not mean that a medicine has no risk.

Supporting source ↗ · Supporting source ↗

Folate and contraception deserve a specific plan

Discuss a folic acid prescription before conception. Guidance differs on the best dose, so ask which dose and duration suit your medicines and local care pathway. The AAN guideline advises at least 0.4 mg daily before and during pregnancy, while recognising uncertainty about the optimal dose. Do not combine supplements without checking the total.

  • Ask your pharmacist to check contraception interactions with every medicine.
  • Use your agreed contraception until any treatment review is complete.
  • Include vitamins, herbal products and non-prescription medicines in the review.

Supporting source ↗ · TGA · pregnancy precautions ↗ · Supporting source ↗ · Supporting source ↗

A positive test or an unexpected pregnancy

Contact your epilepsy team and maternity provider promptly and tell them the medicine names, doses and date of your last period. Continue the prescribed regimen while they arrange advice. If you cannot keep medicines down because of vomiting, seek same-day clinical advice rather than guessing whether to repeat a dose.

  • Keep a dated list of medicines and seizures for the appointment.
  • Ask whom to call out of hours and where to attend if seizures recur.
  • Do not assume that an unexpected pregnancy means the baby will be harmed.

Supporting source ↗ · Supporting source ↗

Monitoring during pregnancy

Pregnancy can change how quickly the body clears some antiseizure medicines. Your team may compare blood levels with a pre-pregnancy baseline and review seizures and adverse effects. A dose increase can sometimes be needed even when you have not had a seizure; that decision belongs to the prescriber.

  • Record blood-test dates, whether the dose was taken before the sample, and any agreed changes.
  • Report changes in seizure pattern, falls or prolonged vomiting promptly.
  • Keep routine maternity screening and epilepsy follow-up appointments.

Supporting source ↗ · Supporting source ↗

Lamotrigine: monitoring during pregnancy and after birth

Lamotrigine is among the better-studied, lower-risk antiseizure medicines for pregnancy when it is appropriate for your epilepsy. It can usually be continued throughout pregnancy under specialist care. No medicine is entirely risk-free, and maintaining seizure control is important for both you and your baby.

Pregnancy often makes the body clear lamotrigine faster, so the blood level can fall even when the dose is unchanged. Ideally, have a baseline blood level before conception while seizures are well controlled, and record the dose and sampling time. If already pregnant without a baseline, contact your neurologist early to agree an individual reference level and monitoring plan.

Blood levels are commonly checked about every four weeks. Your neurologist may agree a four-to-six-week interval according to your results and how pregnancy is affecting you, with earlier checks when needed. Compare with your own effective baseline, alongside seizure control, side effects and missed doses; a laboratory reference range alone is not your personal target.

The dose may need to increase during pregnancy to maintain your usual effective level, even if you have had no seizures. Make every change in consultation with your neurologist, based on blood results and clinical response. Do not increase, reduce or stop lamotrigine yourself.

After delivery, lamotrigine levels can rise rapidly as clearance returns towards normal. If the dose was increased, agree a written reduction plan before birth: reductions usually begin in the first few days after delivery, aiming to return towards the pre-pregnancy dose over the following weeks as your neurologist advises. Arrange an early postnatal blood level, commonly within one to two weeks, and further checks as needed. Do not abruptly return to the old dose without the agreed plan.

  • Use the downloadable Lamotrigine Monitoring During Pregnancy sheet to record the date, pregnancy week or days after birth, blood level with units, dose, and your clinician's instructions.
  • For comparable results, follow your team's sampling instructions, usually before a dose; record when the last dose and blood sample were taken. Do not skip or delay medicine without instructions.
  • Contact your treating team promptly for new marked dizziness, double vision, imbalance or vomiting after birth, or for worsening seizures at any stage. Do not wait for the next scheduled blood test.

Seizures, emergencies and delivery

A convulsive seizure can endanger both the pregnant person and the pregnancy. Call 000 in Australia for a seizure during pregnancy; elsewhere use the local emergency number. A first seizure during pregnancy must not automatically be attributed to epilepsy because pregnancy-related causes need urgent assessment.

  • Tell ambulance staff the gestation, seizure duration and any rescue medicine already given.
  • Prepare a birth plan covering regular medicine, vomiting, sleep and seizure response.
  • Discuss the delivery setting and pain relief with your maternity team; epilepsy alone does not determine the delivery method.

Supporting source ↗ · Supporting source ↗

The first weeks after birth

Arrange help with night feeds and practical tasks before the baby arrives. If doses were raised during pregnancy, obtain a written postnatal adjustment and blood-test plan; levels may rise after delivery. New marked dizziness, double vision or imbalance needs prompt clinical review. Breastfeeding is often possible, with medicine-specific advice.

  • Ask the baby’s clinician what feeding, alertness or weight concerns to watch for.
  • Discuss contraception again; breastfeeding is not reliable contraception.
  • Book the early postnatal epilepsy review before discharge.

Supporting source ↗ · Supporting source ↗

A safer baby-care routine

Make a practical plan that reflects your seizure pattern without assuming you cannot care for your baby. Feeding or changing at floor level can reduce the consequences of a fall. Arrange another adult for bathing and higher-risk tasks when awareness may be affected. Keep the baby’s own safe sleep space separate.

  • Place the baby somewhere safe if a familiar warning occurs and call your helper.
  • Keep essentials together so you do not need to carry the baby repeatedly on stairs.
  • Write down who covers sleep, medicine collection and urgent transport.

What pregnancy registries can and cannot predict

EURAP prospectively followed pregnancies exposed to antiseizure medicines. Its 2024 analysis of 9,840 pregnancies involving eight common monotherapies found different observed malformation rates, with levetiracetam, oxcarbazepine and lamotrigine lowest among the medicines compared. These were not randomised comparisons and do not capture every developmental outcome. Use the findings to discuss a suitable regimen before conception, not to change treatment yourself.

Questions for partners taking valproate

If a partner takes valproate and you are planning conception, arrange a prescriber discussion. Australian advice identifies a possible paternal-exposure risk signal from observational data. Its uncertainty differs from the well-established risks of exposure during pregnancy. Ask about the current product advice and any recommended precautions.

Choose the purpose of the visit

Write your three main priorities before the appointment: understanding the diagnosis, improving control, managing a side effect or making a life decision. Mention urgent changes when booking so the clinic can triage appropriately.

Do not wait for a routine appointment for a seizure emergency or a serious medicine reaction.

Build a one-page story

Describe what happens before, during and after each type of event, the age it began, frequency, injuries and recovery. Include the last event date and whether the pattern is changing.

If a witness can attend with consent, ask them to describe observations in their own words. A safely recorded video can be helpful, but filming must never delay first aid or compromise privacy.

Bring the treatment record

Bring medicine names, formulations, doses and times from labels; record past medicines and why each stopped. Include supplements, contraception, allergies and other diagnoses.

Explain practical barriers such as supply, swallowing, cost, shift work or adverse effects. These are care problems to solve together. Do not change doses while preparing for the visit.

Ask about diagnosis and next tests

Ask what supports the diagnosis and whether there are alternatives. Clarify your seizure type or syndrome if known. Ask what the EEG, scan or other test can and cannot show, and how results will reach you.

If seizures continue, ask whether diagnosis, medicine suitability, adherence and further specialist assessment need review before another treatment is added.

Leave with written next steps

Repeat the plan back in your own words. Ask for a written schedule if treatment changes. Confirm what to do after a missed dose, vomiting, an adverse effect or another seizure.

Clarify first aid, rescue treatment if prescribed, driving, pregnancy plans and any work or water precautions that apply to you. Ask who answers questions between appointments.
