Topiramate for epilepsy

About topiramate

Topiramate is prescribed alone or alongside other medicines to treat epileptic disease and seizures. It can be taken both by adults and by children.

A seizure is a short episode of symptoms which is caused by a burst of abnormal electrical activity in the brain. Topiramate is thought to work mainly by reducing these abnormal electrical activities.

Some medicines are not suitable for people with certain conditions, and sometimes a medicine may only be used if extra care is taken. For these reasons, before you start taking topiramate it is important that your doctor knows:

• אם את בהריון, מנסה להיכנס להריון או מניקה.

• אם יש לך בעיות בתפקוד הכבד שלך, או בתפקוד הכליות שלך.

• אם יש לך הפרעת דם תורשתית נדירה הנקראת פורפיריה.

• אם אתה נוטל תרופות אחרות כלשהן. זה כולל כל תרופה שאתה נוטל שניתן לרכוש ללא מרשם, כמו גם תרופות צמחיות ומשלימות.

• אם אי פעם הייתה לך תגובה אלרגית לתרופה.

• Before you start the treatment, read the manufacturer's printed information leaflet from inside the pack. It will give you more information about topiramate and will provide you with a full list of the side-effects which you may experience from taking it.

• Take topiramate exactly as your doctor tells you to. It is usual for adults to start topiramate treatment on a low dose (25 mg at night), and then for the dose to be increased gradually to a regular maintenance dose, which is taken twice daily. Doses for children are tailored to their age and weight.

• Swallow topiramate tablets with a drink of water. Do not chew the tablets as they have a bitter taste. If you have been prescribed capsules, you can swallow the capsules in the normal way with a drink of water or, if you prefer, you can open up the capsule and sprinkle the contents on to a spoonful of some soft food (porridge, yoghurt or custard for example). Do not chew the contents of the capsules.

• It is important that you drink plenty of water while you are taking topiramate. This is because there is a slight risk that kidney stones can develop and drinking plenty of water reduces this risk.

• Try to get into a habit of taking topiramate at the same time(s) each day. You can take topiramate before or after food.

• If you forget to take a dose, take it as soon as you remember unless it is nearly time for your next dose, in which case leave out the missed dose. Do not take two doses together to make up for a forgotten dose.

• Try to keep your regular appointments with your doctor. This is so your doctor can check on your progress. You may need to have eye tests and weight checks from time to time.

• When you first start a new treatment for epilepsy there may be a change in the number or type of seizures you experience. Your doctor will advise you about this.

• Several different manufacturers make topiramate tablets and capsules, and your treatment could be affected by switching between different formulations. Each time you collect a new supply from your pharmacy, check to see if the tablets/capsules are the same as you have had before. If they are different, discuss this with your pharmacist who will advise you.

• You need to take topiramate every day. Stopping treatment suddenly can cause problems and your doctor may want you to reduce your dose over a few days if this becomes necessary.

• You must avoid getting pregnant while you are taking topiramate. Make sure you have discussed with your doctor which types of contraception are suitable for you and your partner. If you are a woman and want to have a family, make sure you discuss this with your doctor. This is so that you can be given advice from a specialist before you become pregnant.

• People with epilepsy must stop driving. Your doctor will advise you about when it may be possible for you to start driving again. This will usually be after a year free of seizures.

• If you buy any medicines, always check with a pharmacist that they are suitable to take with your other medicines.

Along with their useful effects, most medicines can cause unwanted side-effects although not everyone experiences them. The table below contains some of the most common ones associated with topiramate. You will find a full list in the manufacturer's information leaflet supplied with your medicine. The unwanted effects often improve as your body adjusts to the new medicine, but speak with your doctor or pharmacist if any of the following continue or become troublesome.

חשוב: topiramate has been associated with a number of serious unwanted effects. Although these occur less commonly than the side-effects listed above, you must let your doctor know straightaway if you notice either of the following:

• Problems with your eyesight.

• Mood changes, distressing or depressed thoughts, or feelings about suicide.

If you experience other symptoms which you think may be due to the medicine, speak with your doctor or pharmacist for further advice.

• שמור את כל התרופות מחוץ להישג ידם וראייתם של ילדים.

• יש לאחסן במקום קריר ויבש, הרחק מחום ואור ישיר.

• The oral liquid medicine keeps for one month after first opening. After this time make sure you use a new bottle. It is a good idea to write the date you opened the bottle on the label.
