Asthma is a disease that can inflame the airways, or known as the bronchial tubes, and when the person also suffers from allergies this can make the symptoms of asthma severe in some situations. There are allergies that can affect the sinuses, which include stuffy or runny nasal cavities, sneezing, sinusitis, a tightness in the chest, scratchy throat and dry unproductive coughs. These symptoms can trigger asthma attacks, as in many cases they have already restricted the airways.

People that suffer from both asthma and outdoor allergies need to ensure two things; the first is that the physician is aware of both conditions prior to prescribing medication for either condition so there are no drug interactions.  The second thing this person will benefit from is using an indoor allergen control system, this can filter the air keeping irritants to a minimum and during pollen season wearing a facial mask when outdoors.  These two things will help keep allergy attacks in control, while at the same time keep from triggering asthma attacks.
