Zafirlukast for asthma

About zafirlukast

الربو is a common condition caused by inflammation in the smaller airways of the lungs. The inflammation irritates the muscles around the airways and causes them to constrict. This causes your airways to narrow. It is then more difficult for air to get in and out of your lungs. This causes the typical symptoms of wheeze, chest tightness and shortness of breath. The inflammation also causes the lining of your airways to make extra mucus which causes coughing.

Asthma symptoms can flare up from time to time and there may be no apparent reason why. However, some people find that symptoms are made worse by triggers such as exercise and pollen. These things cause your body to produce chemical substances called leukotrienes, which cause the inflammation. Zafirlukast helps control the symptoms of asthma by blocking the effects of these leukotrienes.

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 zafirlukast 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 أي مشاكل في طريقة عمل الكلى لديك.

• إذا كنت تتناول أو تستخدم 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.

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

• Take zafirlukast exactly as your doctor tells you to. The usual dose is one tablet in the morning and one in the evening.

• Swallow the tablet with a drink of water. You should take it 'on an empty stomach', which means that you should take the tablet about an hour before a meal, or wait until two hours afterwards. This is because your body absorbs less zafirlukast after a meal, which means the medicine is less effective.

• Take zafirlukast regularly every day, even if your asthma is well controlled. Try not to miss any of your doses but if you do forget, take it as soon as you remember. If when you remember, it is almost time to take your next dose then skip the missed dose and take your next dose when it is due. 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. Also, your doctor may want you to have blood tests from time to time to check on the way your liver is working.

• Zafirlukast will not give you immediate relief if you are having an asthma attack. Your doctor will prescribe a reliever inhaler for you to use if this happens. Make sure that you keep it with you all the time in case you need to use it.

• If you find that your asthma symptoms are getting worse, or that you need to use the reliever inhaler more regularly than usual, please contact your doctor or nurse for advice straightaway.

• Do not smoke. Smoking causes severe irritation and damage to the lungs. It will make your condition worse and will reduce the beneficial effects of your medication.

• If you buy any medicines, check with a pharmacist that they are suitable for you to take. Some anti-inflammatory painkillers and aspirin can make asthma symptoms worse in some people.

Along with their useful effects, most medicines can cause unwanted side-effects although not everyone experiences them. The table below contains the most common ones associated with zafirlukast. 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.
