Anatomy of an asthma attack
Asthmatic symptoms are usually quite variable, someone with asthma may go for periods of time without symptoms, and then suddenly have severe episodes for days at a time. The most common symptom is wheezing.
Routine treatment for asthma includes inhaled bronchodilators, injected epinephrine (adrenalin), or intravenous theophylline.
Bronchodilators are drugs which open up or dilate the constricted airways.
For asthma which is strongly triggered by allergies, allergen avoidance can often greatly reduce the amount of medication needed to control the asthma. Taking anti-allergic medications or taking shots for allergy desensitization are other alternatives.
