Which of the following is a common side effect of corticosteroid therapy?

Corticosteroid therapy can lead to a variety of side effects, and among those, headache is relatively common. This may be due to several factors, including changes in metabolism, fluid retention, and the impact of corticosteroids on blood pressure. Additionally, the cumulative effects of corticosteroids on the body, such as increased stress hormone levels, can also contribute to the occurrence of headaches.

Other options, while they can occur in specific situations or with certain individuals, are less commonly associated with corticosteroid therapy in a general context. Anaphylaxis is a severe allergic reaction that is not typically a side effect of corticosteroids themselves but rather associated with allergens or other specific medications. Bronchospasm is often an asthmatic response and not a direct effect of corticosteroids, which are usually prescribed to mitigate such reactions. Laryngeal edema, though a serious condition, is also not a common side effect of corticosteroid use and typically arises from allergic reactions or infections.

Thus, headaches are a more prevalent side effect among patients undergoing corticosteroid treatment.
