Montelukast for asthma

About montelukast

Asthma 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. Montelukast helps control the symptoms of asthma by blocking the effects of these leukotrienes. It is especially helpful for people whose asthma symptoms are brought on by exercise or seasonal allergies such as hay fever.

Before taking montelukast

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 montelukast it is important that your doctor knows:

• Wenn Sie schwanger sind, ein Kind erwarten oder stillen.

• Wenn Sie andere Arzneimittel einnehmen oder verwenden. Dazu gehören alle Arzneimittel, die Sie einnehmen und die rezeptfrei erhältlich sind, sowie pflanzliche und ergänzende Arzneimittel.

• Wenn Sie schon einmal eine allergische Reaktion auf ein Arzneimittel hatten.

How to take montelukast

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

• Take montelukast once every day, in the evening. The dose for adults is one 10 mg tablet. If montelukast has been prescribed for your child, the dose will depend on their age: it is 4 mg for children aged from 6 months to 5 years, and 5 mg for children aged from 6 years to 14 years.

• The 10 mg (adult) tablet can be swallowed with a drink of water and can be taken either before or after food.

• If your child has been prescribed tablets to take, they are cherry-flavoured chewable tablets. The tablets should preferably be taken 'on an empty stomach', which means your child should take them about an hour before a meal, or wait until two hours afterwards. They should be chewed before being swallowed.

• If your child has been prescribed granules (in sachets), these can simply be poured into the mouth and swallowed. Alternatively if your child prefers, you can mix the granules into a small amount of cold, soft food (such as yoghurt, ice cream or mashed fruit or vegetables). It doesn't matter if montelukast granules are taken before or after meals but they should not be mixed into drinks or hot food.

• Remember to take montelukast regularly every day, even if your asthma is well controlled. Try not to miss any of your doses but if you do forget, just take your next dose when it is due. Do not take two doses together to make up for a forgotten dose.

Das Beste aus Ihrer Behandlung herausholen

• Try to keep your regular appointments with your doctor. This is so your doctor can check on your (or your child's) progress.

• Montelukast 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.
