If you have asthma, there's a good chance that an underlying allergy —whether it's to dust mites, pollen, cockroaches, or cat dander—is playing a key role in your breathing problems. (About 60% to 90% of people with asthma have allergic asthma.)
The first step is to avoid the allergen, but that's not always possible or sufficient to stop symptoms, like coughing, wheezing, and shortness of breath.
That's where medication comes in. Here are some common drugs used to treat allergic asthma.

Anyone can have asthma, including infants and adolescents. The tendency to develop asthma is often inherited; in other words, asthma can be more common in certain families. Moreover, certain environmental factors, such as respiratory infections, especially infection with respiratory syncytial virus or rhinovirus, may bring the onset of asthma. Recent medical reports suggest that patients with asthma are likely to develop more severe problems due to H1N1 infection. It has also been suggested that there is an association between day-care environment and wheezing. Those who started day care early were twice as likely to develop wheezing in their first year of life as those who did not attend day care. Other environmental factors, such as exposure to smoke, allergens, automobile emissions, and environmental pollutants, have been associated with asthma.
