توبيراميت للوقاية من الصداع النصفي

About topiramate

In people with الصداع النصفي, it is thought that some chemicals in the brain increase in activity and, as a result, parts of the brain then send out confused signals which result in the symptoms of headache and sickness. Why people with migraine should develop these chemical changes is not clear and many migraine attacks occur for no apparent reason. For some people, however, there may be things which trigger an attack, like certain foods or drinks.

Topiramate is classed as an antiepileptic medicine. It is usually used to prevent seizures in people with epilepsy and there is another leaflet called توبيراميت لعلاج الصرع which gives more information about this. However, topiramate has also been found to prevent migraine attacks from occurring. When used for migraine, it may not completely stop every migraine attack, but the number and severity of attacks are often reduced.

Before taking topiramate

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:

• إذا كنتِ حاملاً، تحاولين الإنجاب أو تقومين بالرضاعة الطبيعية.

• إذا كان لديك أي مشاكل في طريقة عمل الكبد لديك، أو في طريقة عمل الكلى لديك.

• إذا كنت تعاني من اضطراب دم وراثي نادر يسمى البورفيريا.

• إذا كنت تتناول أي أدوية أخرى. يشمل ذلك أي أدوية تتناولها والتي يمكن شراؤها بدون وصفة طبية، بالإضافة إلى الأدوية العشبية والمكملات الغذائية.

• إذا كنت قد تعرضت في أي وقت مضى لرد فعل تحسسي تجاه دواء.

How to take topiramate

• 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 to start topiramate treatment on a low dose (25 mg at night), and then for the dose to be increased gradually. A usual maintenance dose is 50-100 mg daily, taken either as a single dose or divided into two doses over the day.

• 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.

• إذا نسيت تناول جرعة، فتناولها بمجرد أن تتذكر، إلا إذا كان الوقت قد اقترب لتناول الجرعة التالية، وفي هذه الحالة اترك الجرعة الفائتة. لا تتناول جرعتين معًا لتعويض الجرعة المنسية.
  

تحقيق أقصى استفادة من علاجك

• 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.

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

• This medicine is used to help prevent migraines, although it is unlikely to stop your migraine attacks completely. If a migraine attack occurs, you can take painkillers or a triptan to treat the pain during an attack.

• A number of things can trigger migraine in some people. These can include some foods (for example, cheese, chocolate, and red wine), worry, bright sunlight, too much or too little sleep, and skipping meals. If you are not sure if these things trigger a migraine for you, it may help for you to keep a migraine diary. Note down when and where each migraine attack started, what you were doing, and what you had eaten that day. A pattern may emerge and it may be possible for you to avoid some of the things that trigger an attack.

• بعض الأشخاص الذين يعانون من نوبات الصداع النصفي المتكررة قد يكونون في الواقع يعانون من صداع ناتج عن الأدوية. الصداع الناتج عن الأدوية (ويُسمى أيضًا صداع الإفراط في استخدام الأدوية) يحدث بسبب تناول المسكنات بشكل مفرط. إذا كنت تستخدم المسكنات لأكثر من يومين في الأسبوع بشكل منتظم، فقد تكون معرضًا لخطر ذلك. يجب عليك التحدث مع طبيبك إذا كنت تشك في ذلك.

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

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.

مهم: 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 على الفور if you notice either of the following:
