Zonisamide per l'epilessia

About zonisamide

Avere l'epilessia means that you have had more than one unexplained fit, or seizure. A seizure is a short episode of symptoms caused by a burst of abnormal electrical activity in your brain. With partial seizures (also called focal seizures), the burst of electrical activity is in one part of your brain and therefore you tend to have localised or 'focal' symptoms. Because different parts of the brain control different functions, your symptoms will depend on which part of your brain is affected. Partial seizures can sometimes develop into seizures which affect all of your brain. These are called secondary generalised seizures. Symptoms that may occur during a seizure can affect your muscles, sensations, behaviour, emotions, consciousness, or a combination of these.

The seizures can be prevented in most people by suitable antiepileptic medication. Zonisamide works by stabilising the electrical activity of your brain. This helps to prevent the seizures from occurring.

Before taking zonisamide

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 (or your child if you are their carer) start taking zonisamide it is important that your doctor knows:

• If you have problems with the way your liver works or with the way your kidneys work.

• If you have ever had a kidney stone.

• If you have ever had any problems with your vision or with your eyes - for example, raised pressure in your eye(s), a condition known as glaucoma.

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

• 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.

• If you have ever had an allergic reaction to a medicine. This is especially important if you have had an allergic reaction to a sulfonamide antibiotic medicine.

• If you have an allergy to peanuts or to soya.

How to take zonisamide

• Before you start the treatment, read the manufacturer's printed information leaflet from inside the pack and any additional information you are given by your doctor. The manufacturer's leaflet will give you more information about zonisamide and will provide you with a full list of the side-effects which you may experience from taking it.

• Take zonisamide exactly as your doctor tells you to. You will be prescribed either one or two doses to take each day. Your dose will be printed on the label of the pack to remind you about what the doctor said. There are several different strengths of zonisamide capsules. It is usual to start treatment on a low dose, and then for the dose to be increased gradually to a regular maintenance dose.

• It is important you try to take your doses at the same times each day. Having a routine will help you to remember to take your doses regularly.

• Swallow the capsule with a drink of water. You can take zonisamide either before or after a meal.

• Se dimentichi di prendere una dose, prendila appena te ne ricordi. Se quando te ne ricordi è quasi ora della dose successiva, prendi la dose successiva quando è il momento, ma salta la dose dimenticata. Non prendere due dosi insieme per compensare una dose dimenticata.

Ottenere il massimo dal tuo trattamento

• 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.

• Make sure you drink plenty of water while you are on zonisamide. This is because some people who have taken zonisamide have developed kidney stones - drinking plenty of water will help to prevent this. Occasionally, people taking zonisamide have had heatstroke - drinking plenty of water will also help to prevent this. This is especially important for active children during warm weather, and for people working in a hot environment:

  • Symptoms of heat stroke are: a hot dry skin, feeling confused, muscle cramps, rapid breathing, and a rapid heartbeat.

  • What to do if you suspect heat stroke: move into a cool place and drink cold water. Get medical help straightaway and, in the meantime, sponge your (or your child's) skin with cool water.

• Cerca di mantenere i tuoi appuntamenti regolari con il tuo medico. Questo è per permettere al tuo medico di controllare i tuoi progressi.

• 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.

• Many antiepileptic medicines can harm an unborn child. If you are a woman, make sure you have discussed with your doctor which types of contraception are suitable for you and your partner. If you want to have a family, discuss this with your doctor so that you can be given advice from a specialist before you become pregnant. You should use effective contraception during treatment with zonisamide and for at least one month after stopping.

• Different formulations of some antiepileptic medicines can act in a slightly different way in your body. Because of this, your doctor may recommend that you continue to take zonisamide from the same manufacturer each time you obtain a new supply. If so, each time you collect a prescription, check to make sure your supply looks the same and that the name is the same. If you are unsure, or if you have any questions about your prescription, please ask your pharmacist to advise you.

• Le persone con epilessia devono smettere di guidare inizialmente. Il tuo medico ti consiglierà su quando potrebbe essere possibile ricominciare a guidare. Di solito sarà dopo un anno senza crisi epilettiche.

• Se bevi alcolici, chiedi consiglio al tuo medico. Il tuo medico potrebbe consigliarti di non bere alcolici mentre stai assumendo questo medicinale.

• Se acquisti dei medicinali, verifica con un farmacista che siano adatti da assumere insieme al tuo farmaco antiepilettico.

• You need to take zonisamide regularly every day. Do not stop taking it unless your doctor tells you to stop. Stopping treatment suddenly can cause problems and your doctor will want you to reduce your dose gradually if this becomes necessary.

Can zonisamide cause problems?

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 zonisamide. 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.

Se si verificano altri sintomi che ritieni possano essere dovuti alle capsule, parla con il tuo medico o farmacista per ulteriori consigli.

How to store zonisamide

• 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.

• 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.
