Use of QVAR with a spacer device in children less than 5 years of age is not recommended. In vitro dose characterization studies were performed with QVAR 40 mcg/actuation with the OptiChamber and AeroChamber Plus ® spacer utilizing inspiratory flows representative of children under 5 years old. These studies indicated that the amount of medication delivered through the spacing device decreased rapidly with increasing wait times of 5 to 10 seconds as shown in Table 2. If QVAR is used with a spacer device, it is important to inhale immediately.
Inhaled corticosteroids are prescribed for patients of all ages to treat different levels of persistent asthma. They work by dampening down the inflammation in the airways, and are the most effective agents for treating asthma. As a result, asthma symptoms and sudden acute attacks occur less often. To be effective, they need to be taken once or twice every day as prescribed by your doctor. They are of no benefit when used for symptoms, unlike bronchodilators or when taken on an odd occasion. Inhaled corticosteroids are a maintenance medicine that helps to prevent severe asthma symptoms.
There are many effective medicines to treat asthma. Most people with asthma need two kinds: quick-relief medicines and long-term control medicines. Immunotherapy ( allergy shots ) can also be helpful.
Patients may be reluctant to take medication because of cost or the potential side effects. If you have such concerns, talk with your allergist. Your allergist will work with you to find the right medicine, or combination of medicines, to manage your asthma and will adjust the dosage based on your symptoms and control. The goal is to have you feel your best with the least amount of medicine.
