Can Chronic Steroid Use Cause Increased Anxiety?
Yes, chronic steroid use definitively causes increased anxiety and other mood disturbances, with anxiety occurring in over 30% of patients on prolonged corticosteroid therapy. 1, 2
Evidence for Steroid-Induced Anxiety
Mood disturbances, including anxiety, are well-documented side effects of both short- and long-term corticosteroid therapy. 1 The American Academy of Otolaryngology-Head and Neck Surgery explicitly lists "mood disorder" as a documented side effect of steroid therapy, and multiple guidelines confirm that sleep disturbances and mood changes occur in more than 30% of patients taking corticosteroids. 1, 2
Prevalence and Timing
- Anxiety disorders develop in approximately 27% of patients on prolonged corticosteroid therapy, with onset typically occurring during the first weeks of treatment. 3
- In a prospective study of patients on chronic corticosteroid therapy for skin diseases, anxiety disorders were identified in 11% of cases as a standalone diagnosis, with an additional 16% experiencing depressive disorders. 3
- A large US claims database analysis found that glucocorticoid users (as adjunctive therapy) had significantly higher risk for depression (adjusted hazard ratio 1.5) and a trend toward increased anxiety (adjusted hazard ratio 1.3). 1
Mechanism and Risk Factors
The anxiety-inducing effects of corticosteroids appear to be dose-dependent and related to duration of therapy. 3 Key risk factors include:
- Higher doses of corticosteroids significantly increase risk 3
- Personal psychiatric history is a statistically significant risk factor 3
- Age over 40 years and female gender show higher prevalence of anxiety disorders 3
- Duration exceeding 6 weeks substantially increases adverse psychiatric effects 1, 2
Clinical Manifestations
Neuropsychiatric effects include insomnia, restlessness, nervousness, and anxiety ranging from mild to moderate severity. 2 The American Society of Hematology specifically notes that treating physicians should assess health-related quality of life including mental status while patients receive corticosteroids, given their significant impact on mental health. 1
Special Considerations for Patients with Pre-existing Anxiety
Patients with a history of anxiety or mood disorders are at particularly high risk for steroid-induced psychiatric complications. 3 The prospective study found that personal psychiatric history was one of only two statistically significant risk factors for developing anxiety and depressive disorders during corticosteroid therapy. 3
Monitoring Recommendations
- Close monitoring for hypertension, hyperglycemia, sleep and mood disturbances is required regardless of steroid duration or type. 1
- Assessment of health-related quality of life, including depression, fatigue, and mental status, should occur throughout corticosteroid treatment. 1
- Psychiatric examination prior to prescribing long-term corticosteroid therapy should be standard practice to identify at-risk patients. 3
Management Implications
The American Society of Hematology strongly recommends against prolonged courses (>6 weeks) of corticosteroids due to increased risk of side effects, including psychiatric complications. 1 The balance of effects favors shorter courses of corticosteroids (≤6 weeks) over longer courses, even with very low certainty in the evidence, because high-quality evidence demonstrates harm with prolonged exposure. 1
Treatment Approach
- When anxiety or mood disturbances develop, pharmacological treatment and supportive psychotherapy show favorable outcomes in most patients. 3
- Consider steroid-sparing agents when long-term therapy is anticipated to reduce corticosteroid-related psychiatric complications. 2
- Educate patients about potential psychiatric risks and encourage them to seek medical attention if they experience mental health symptoms. 4
Common Pitfalls to Avoid
Underestimating the impact of sleep disturbances and mood changes on quality of life is a significant clinical pitfall. 1 Healthcare providers must recognize that patients may use medically prescribed corticosteroids for non-pain-related conditions such as anxiety, depression, and insomnia, despite evidence that long-term use can worsen these conditions. 1
Psychiatric symptoms including mood swings, anxiety, and depression may also occur during steroid withdrawal, not just during active treatment. 5 This withdrawal syndrome must be distinguished from the underlying condition being treated and from active steroid-induced psychiatric effects.
