If relievers are used before exercise they can reduce the chances of getting asthma symptoms.
Preventers and how they work
Preventers protect the lining of the airways and reduce the risk of severe asthma attacks. They calm down the inflammation in the airways and stop them from being so sensitive.
The drugs that are used as preventer treatments are called anti-inflammatories, which when taken regularly can calm down the irritated airways, reducing the swelling in the linings of the airways, as well as reducing the overproduction of mucus. This means that the airways are less likely to react badly when they come across an asthma trigger.
The protective effect of a preventer builds up over a period of time so they need to be taken every day, usually morning and evening, even if you are feeling well.
When you first start using them, it may take up to 14 days before you notice any improvement in your asthma symptoms. If your preventer is a non-steroidal it can take longer - from four to six weeks.
What to do if you think your medication is not working
If you notice any of the following, it could be an indication that your asthma medication is not working:
If you experience any of these symptoms, then you should see your doctor or asthma nurse.
What to do if you experience side effects
Always talk to your doctor or asthma nurse about any side effects that you experience, particularly if you have recently had any adjustments to your treatment. They will advise you whether to continue with your prescribed treatment.
If you purchase over-the-counter remedies from a chemist, always check with the pharmacist that they are safe to take for people with asthma.
Never stop your asthma medication without first consulting your doctor or nurse.
Remember to record details in your asthma diary
Some people find keeping a written record or asthma diary, can be helpful in managing their asthma.
This record or diary may include the number of times that you have needed to use your reliever inhaler, as well as whether you have experienced any asthma symptoms. You may also wish to note side effects from your treatment. The diary will then form a useful basis for discussion at the next follow up or review with your doctor or asthma nurse.
