It is very important that you or your child take all the medicines that the doctor prescribes. A common mistake is to stop taking controller asthma medications when the symptoms improve. Symptom improvement is due to the medication, it does not mean the asthma is gone! Leaving asthma untreated has much bigger risks than any risks associated with the medications. Asthma may improve or worsen with changes in season and exposure to asthma triggers, therefore it is important to have regular check-ups to evaluate and monitor your asthma as medication changes are necessary from time to time.
