Which statement reflects medication-induced depressive disorder?

Which statement reflects medication-induced depressive disorder?

• A. Steroids, beta blockers, isotretinoin, and interferons
• B. Steroids only
• C. Isotretinoin only
• D. Beta blockers only

Answer: (A)

Depression that is triggered by a medication is a known phenomenon, and several drugs have well-documented associations with this effect. The statement that includes steroids, beta blockers, isotretinoin, and interferons reflects this pattern because each of these drug classes can induce depressive symptoms in some people during treatment, and symptoms often improve after the medication is stopped. Steroids can alter mood through effects on the HPA axis and neurotransmitter systems, leading to mood swings and depressive symptoms with higher doses or prolonged use. Isotretinoin, a retinoid used for acne, has been linked to depression and suicidality in some patients, likely through complex brain signaling pathways affected by retinoids. Interferons, especially IFN-alpha used in certain infections and cancers, can cause depressive symptoms via cytokine effects on brain chemistry, including serotonin and dopamine pathways. Beta blockers can contribute to depressive symptoms in a subset of patients, particularly lipophilic ones that cross the blood–brain barrier and influence CNS activity. Because each of these drug classes can produce depressive symptoms during treatment and symptoms may remit after discontinuation, the statement that lists all of them best captures medication-induced depressive disorder.
