What KERRON is used for
KERRON is used to control epilepsy.
Epilepsy is a condition where you have repeated seizures. There are many different types of seizures, ranging from mild to severe.
This medicine belongs to a group of medicines called antiepileptics. These medicines are thought to work by controlling brain chemicals which send signals to nerves so that seizures do not happen.
KERRON may be used alone, or in combination with other medicines, to treat your condition.
Your doctor may have prescribed this medicine in addition to your current therapy.
Ask your doctor if you have any questions about why this medicine has been prescribed for you.
There is no evidence that this medicine is addictive.
This medicine is available only with a doctor’s prescription.
The safety and effectiveness of KERRON has not been established in patients less than 4 years of age.
Before you take KERRON
When you must not take it:
Do not take KERRON if you have an allergy to any of the ingredients listed at the end of this leaflet.
Some of the symptoms of an allergic reaction may include:
- shortness of breath;
- wheezing or difficulty breathing;
- swelling of the face, lips, tongue or other parts of the body; or
- rash, itching or hives on the skin.
KERRON oral solution contains maltitol. Do not use this medicine if you have hereditary problems of fructose intolerance.
Do not take this medicine after the expiry date (EXP) printed on the pack.
Do not take this medicine if the solution is not clear, if the tablets do not look quite right or the packaging is torn or shows signs of tampering.
If this medicine has expired or is damaged, return it to your pharmacist for disposal.
If you are not sure whether you should start taking this medicine, talk to your doctor or pharmacist.
Before you start to take it:
Tell your doctor or pharmacist if you have allergies to:
- any other medicines, especially barbiturates (such as phenobarbitone) or any other antiepileptic medicines (such as carbamazepine, lamotrigine or valproate); or
- any other substances, such as foods, preservatives or dyes.
Tell your doctor if you have or have had any medical conditions, especially the following:
- kidney problems; or
- liver problems.
Tell your doctor if you are pregnant or intend to become pregnant.
KERRON may affect your developing baby if you take it during pregnancy. However, it is very important to control your seizures while you are pregnant. Your doctor will outline and weigh up all the risks and benefits of taking KERRON during pregnancy to help decide whether or not you should take it.
Tell your doctor if you are breastfeeding or plan to breast-feed.
The active ingredient in KERRON passes into breast milk and there is a possibility that your baby may be affected. Your doctor will discuss the risks and benefits of using KERRON if you are breastfeeding.
If you have not told your doctor or pharmacist about any of the above, tell them before you start taking KERRON.
Taking other medicines:
Tell your doctor or pharmacist if you are taking any other medicines, including any that you buy without a prescription from your pharmacy, supermarket or health food shop.
KERRON does not interact with the oral contraceptive pill.
However, you may be given KERRON together with other antiepileptic medicines that do interact and may affect the effectiveness of your contraceptive. Your doctor may advise you to use an additional method of contraception if you take KERRON with other antiepileptic medicines.
How to take KERRON
How much to take:
Follow all directions given to you by your doctor carefully.
They may differ from the information contained in this leaflet.
Your doctor will tell you how much KERRON you will need to take each day. This may depend on your age, your condition and whether or not you are taking any other medicines.
For patients 12 years of age and older, the dosage is generally between 1000 mg and 3000 mg each day, taken in two doses.
For the oral solution, 1000 mg equates to 10 mL and 3000 mg equates to 30 mL.
For children 4 to 11 years of age the doctor will calculate the dosage based on the child's weight and tell you how much to give. The medicine is to be given twice daily.
Your doctor may start you on a low dose of KERRON first.
Your doctor will slowly increase the amount of medicine until you are taking enough to control your epilepsy and you are not having seizures.
If you do not understand the instructions on the pack, ask your doctor or pharmacist for help.
How to take it:
Swallow the tablets whole with a glass of water.
Use the syringe provided in the cardboard box to measure the exact quantity of oral solution prescribed by your doctor.
KERRON oral solution may be diluted in a glass of water or baby's bottle.
Open the bottle, press the cap and turn it anticlockwise (figure 1).
Separate the adaptor from the syringe (figure 2). Insert the adaptor into the bottle neck (figure 3). Ensure it is firmly attached.
Take the syringe and put it in the adaptor opening (figure 4). Turn the bottle upside down (figure 5).
Fill the syringe with a small amount of solution by pulling the piston down (figure 5A), then push the piston upward in order to remove any possible bubble (figure 5B). Pull the piston down to the graduation mark corresponding to the quantity in millilitres (ml) prescribed by your doctor (figure 5C).
Turn the bottle the right way up (figure 6A). Remove the syringe from the adaptor (figure 6B).
Empty the contents of the syringe in a glass of water or baby's bottle by pushing the piston to the bottom of the syringe (figure 7).
Drink the whole contents of the glass/baby's bottle. Close the bottle with the plastic screw cap. Wash the syringe with water only (figure 8).
When to take it:
Take KERRON twice a day, once in the morning and once at night. Take it at about the same time each day.
Taking your medicine at the same time each day will have the best effect. It will also help you remember when to take it.
It does not matter if you take this medicine before or after food.
If you forget to take it:
Contact your doctor if you have missed one or more doses.
Do not take a double dose to make up for the dose that you missed.
This may increase the chance of you getting an unwanted side effect.
If you are not sure what to do, ask your doctor or pharmacist.
If you have trouble remembering to take your medicine, ask your pharmacist for some hints.
How long to take it
Most antiepileptic medicines take time to work, so do not be discouraged if you do not feel better straight away.
Continue taking your medicine for as long as your doctor tells you to.
This medicine helps control your condition, but does not cure it. Therefore you must take your medicine every day, even if you feel well.

Stopping KERRON suddenly may cause unwanted side effects or make your condition worse. Your doctor will slowly reduce your dose before you can stop taking it completely.
If you take too much (overdose):
Immediately telephone your doctor or the Poisons Information Centre (telephone 13 11 26) for advice, or go to Accident and Emergency at the nearest hospital, if you think that you or anyone else may have taken too much KERRON. Do this even if there are no signs of discomfort or poisoning.
