Asthma inhaler: overuse is dangerous.

Nonprescription inhalers can provide relief for many of the nation's 8,000,000 asthma sufferers whose symptoms are mild, but these popular devices can be dangerous if used continually, warns Abba 1. Terr, a Stanford University Medical Center allergist. Regular use of the devices may mask serious problems that remain untreated. even though symptoms are relieved, Continued reliance also may build up a tolerance, reducing their effectiveness and, in some cases, making the condition worse.

"In recent years, we've been noticing an increase in serious problems and even deaths from asthma. Some of these situations have been linked to excessive reliance on inhaled bronchodilators, both nonprescription and even certain prescription forms. In a sense, these inhalers work too well. They give sufferers a false sense that their problem is solved." When a patient inhales through the hand-held device, a drug intended to widen the narrow airways in the chest is released.

"Any person who relies on a nonprescription inhaler on a daily basis should consult a physician, even if the person is getting relief from the inhaler," Terr suggests. For chronic sufferers, there may be more effective forms of treatment that attack the causes of asthma, not just the symptoms. For example, prescription steroid inhalers - which must be used carefully and monitored closely - can offer fewer side effects and improved quality of life.
