Question 1

My patient drinks heavily and has anxiety - which came first, and how do I treat both?

Accepted Answer

Substance-induced anxiety must be distinguished from primary anxiety with comorbid substance use. The DSM-5-TR diagnostic key is temporal: substance-induced anxiety develops during or within one month of intoxication/withdrawal and resolves after verified abstinence; primary anxiety persists. Self-medication with alcohol or drugs occurs in 7.9-35.6% of individuals with anxiety disorders (Bolton 2006, PMID 17102705) and is associated with increased suicidal ideation (aOR 1.66) and suicide attempts (aOR 2.23). Benzodiazepines carry significant risk in patients with SUD history due to cross-tolerance with alcohol and additive CNS/respiratory depression. SSRIs are first-line pharmacotherapy in the SUD-anxiety population. Integrated treatment addressing both conditions simultaneously is recommended over sequential treatment when both are severe.

Question 2

How do I distinguish primary anxiety from substance-induced anxiety?

Accepted Answer

Question 3

How long should I wait post-abstinence before diagnosing primary anxiety?

Accepted Answer

Substance-induced anxiety must be distinguished from primary anxiety with comorbid substance use. The DSM-5-TR diagnostic key is temporal: substance-induced anxiety develops during or within one month of intoxication/withdrawal and resolves after verified abstinence; primary anxiety persists.

Question 4

Why are benzodiazepines contraindicated in the SUD-anxiety population?

Accepted Answer

Substance-induced anxiety must be distinguished from primary anxiety with comorbid substance use. The DSM-5-TR diagnostic key is temporal: substance-induced anxiety develops during or within one month of intoxication/withdrawal and resolves after verified abstinence; primary anxiety persists.
