My daughter is currently taking oral corticosteroids for her asthma. I have noticed that she has an increase in appetite. Is that a side effect of the medication?

A change in appetite is a common side effect of oral corticosteroids. Others effects of oral steroids include decreased growth, cataracts, and elevated blood sugar, among others. Despite all these undesirable side effects, corticosteroids are the most effective medications available to control asthma, a respiratory disorder which if uncontrolled, can be life threatening. However, when one takes corticosteroids by mouth, the entire body is exposed to the same dose that the lungs need. The development of topical corticosteroids was a big step in improving asthma therapy while minimizing side effects. Inhaled corticosteroids allow doctors to deliver effective doses of corticosteroids to the lungs while greatly minimizing the amount of drug that the rest of the body is exposed to. Nonetheless, systemic side effects are sometimes seen if the dose is high enough, or the patient sensitive enough. I'd suggest discussing this with your daughter's physician. If her asthma is under good control, it may be appropriate to lower her dose, or perhaps other adjustments can be made in her treatment regimen to minimize her systemic exposure to her oral corticosteroids.

Good luck, Dr. White
