This study seeks to compare the effectiveness of a single dose of oral dexamethasone versus 5 days of oral prednisone in the treatment of mild to moderate asthma exacerbations to prevent relapse with an unscheduled return visit to a health care provider for additional asthma treatment within 14 days. The investigators hypothesize that the two treatments will be equally effective in relapse prevention.

Primary Outcome Measures:
  • Relapse for worsening asthma within 14 days of ED visit [ Time Frame: 14-17 days ]
    Relapse will be defined as un unscheduled visit to see a doctor for worsening asthma within 14 days following their ED visit for asthma

Secondary Outcome Measures:
  • Compliance [ Time Frame: 14 days ]
    Completion of study medications

  • Side effects [ Time Frame: 14 days ]
    Assess if any side effects from the study medications

  • Symptoms persistence or improvement [ Time Frame: 14-21 days ]
    Assessment of current rescue inhaler use and symptoms such as wheezing, cough, shortness of breath, and difficulty with activities of daily living

Detailed Description:

Dexamethasone and Prednisone are both systemic corticosteroids. The study will compare a single dose of oral dexamethasone to 5 days of oral prednisone in the treatment of asthma. Oral corticosteroids are commonly prescribed following an asthma exacerbation as it has been demonstrated that these medications prevent relapse.

Oral prednisone is the most common corticosteroid prescribed for asthma relapse prevention. The half life is around 4 hours and is typically prescribed for minimally 5 days.

The study is evaluating the efficacy of a single dose of dexmethasone. The drug's efficicacy has been shown to be longer acting and up to 72 hours. A single dose would eliminate the need for a prescription for a drug like prednisone to hopefully improve compliance.
