Sodium valproate for epilepsy

About sodium valproate

Sodium valproate is prescribed 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. Sodium valproate works by reducing these abnormal electrical activities.

There is also a medicine with a similar name but which is used to treat a different condition. See the medicine leaflet called Valproate semisodium for bipolar disorder for more information about this.

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 sodium valproate it is important that your doctor knows:

• Se sei incinta, stai cercando di avere un bambino o stai allattando.

• If you or a close member of your family have liver problems.

• Se hai problemi con il funzionamento dei tuoi reni.

• If you have an inflammatory condition called systemic lupus erythematosus (also called lupus or SLE).

• Se hai un raro disturbo ereditario del sangue chiamato porfiria.

• If you have been told you have a mitochondrial disorder or a urea cycle disorder.

• Se stai assumendo altri medicinali. Questo include qualsiasi medicinale che stai assumendo e che è disponibile per l'acquisto senza prescrizione medica, così come i medicinali a base di erbe e complementari.

• Se hai mai avuto una reazione allergica a un medicinale.
  

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

• Take sodium valproate exactly as your doctor tells you to. It is usual to start treatment on a low dose, and then for the dose to be increased gradually to a regular maintenance dose. Most people take one or two doses daily. Doses for children are tailored to their age and weight.

• Read the printed information with your supply for more details about how you should take your doses. For example, many brands of sodium valproate must be taken with or just after food. Some brands of tablets are crushable to make them easier to swallow. Others must be swallowed whole without crushing or chewing. The label on the pack and the printed information leaflet from inside will provide this sort of information for you. Alternatively, you can ask your pharmacist to advise you.

• If you have been prescribed sachets (granules), you can swallow the granules by pouring them into your mouth and swallowing them with a drink of water. If you prefer, you can sprinkle the granules on to some soft food (yoghurt or ice cream, for example) or into a cool drink. Do not chew the granules.

• Try to get into a habit of taking sodium valproate at the same time(s) each day. This will help you avoid missing doses.

• If you do 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.

• Quando inizi un nuovo trattamento per l'epilessia, potrebbe esserci un cambiamento nel numero o nel tipo di crisi che sperimenti. Il tuo medico ti consiglierà a riguardo.

• Try to keep your regular appointments with your doctor. This is so your doctor can check on your progress. You will need to have blood tests before you start the medicine and while you are taking it.

• There are several brands of sodium valproate available and your treatment could be affected by switching between brands made by different manufacturers. Each time you collect a new supply from your pharmacy, check to see if it looks the same as you have had before. If it is different, please discuss this with your pharmacist who will advise you.

• You need to take sodium valproate every day. Stopping treatment suddenly can cause problems. If it becomes necessary for the treatment to stop, your doctor will want you to reduce your dose over a few days.

• Sodium valproate can harm an unborn child so you must avoid getting pregnant while you are taking sodium valproate. 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, discuss this with your doctor so that you can be given advice from a specialist about alternative treatment prima di rimanere incinta.

• 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.

• Durante il trattamento per l'epilessia, c'è un piccolo rischio di sviluppare cambiamenti d'umore, pensieri angoscianti e sentimenti di suicidio. Se ciò accade, devi informare immediatamente il tuo medico.

• If you buy any medicines, always check with a pharmacist that they are suitable to take with your other medicines. Medicines which contain aspirin (such as some cold or flu remedies and painkillers) can interfere with sodium valproate.

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 sodium valproate. 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.

• Tenere tutti i medicinali fuori dalla portata e dalla vista dei bambini.

• Conservare in un luogo fresco e asciutto, lontano da fonti di calore e luce diretta.
