The FDA has not approved any antidepressants specifically for “geriatric depression” as a distinct indication. However, many antidepressants are approved for major depressive disorder (MDD) in adults generally (often 18+), and some have more extensive evidence and clinical favorability for use in older adults (age 65+) due to better tolerability and safety profiles.
Here’s a breakdown:
I. Antidepressants Commonly Used (Though Not FDA-Approved Specifically for Geriatric Depression)
These drugs are FDA-approved for MDD in adults, and are widely used off-label in elderly patients based on strong clinical practice guidelines:
1.
Selective Serotonin Reuptake Inhibitors (SSRIs)
- Sertraline (Zoloft) – often preferred in the elderly due to efficacy and safety.
- Escitalopram (Lexapro) – well tolerated; minimal drug interactions.
- Citalopram (Celexa) – caution with QTc prolongation; dose limits for those over 60.
- Fluoxetine (Prozac) – long half-life; may cause agitation or insomnia in sensitive patients.
- Paroxetine (Paxil) – generally avoided in the elderly due to strong anticholinergic effects.
2.
Serotonin-Norepinephrine Reuptake Inhibitors (SNRIs)
- Venlafaxine (Effexor XR) – used in elderly, especially with comorbid pain.
- Duloxetine (Cymbalta) – also approved for neuropathic pain; useful in elderly with chronic pain syndromes.
- Desvenlafaxine (Pristiq) – similar to venlafaxine; lower drug interaction profile.
3.
Atypical Antidepressants
- Bupropion (Wellbutrin) – activating; useful if fatigue/apathy dominates. Avoid in patients with seizure risk.
- Mirtazapine (Remeron) – helpful in elderly with insomnia, anorexia, or weight loss.

III. Newer Antidepressants with Cognitive Consideration
- Vortioxetine (Brintellix/Trintellix):
- FDA-approved for MDD.
- Studies suggest it may enhance cognitive function in elderly patients with depression (improved executive function and processing speed).
- Generally well tolerated.
IV. Cautions in Geriatric Use
- Avoid tricyclic antidepressants (TCAs) (e.g., amitriptyline, nortriptyline) unless carefully supervised—due to anticholinergic effects, fall risk, cardiac toxicity.
- MAOIs are rarely used in the elderly due to dietary restrictions and high side effect profiles.
- Paroxetine is often discouraged in older adults due to its strong anticholinergic effects.
Clinical Guidelines and Considerations
- Start low and go slow: Use the lowest possible effective dose and titrate carefully.
- Monitor electrolytes, QT interval, and drug-drug interactions (especially due to polypharmacy).
- Be mindful of falls, cognition, and frailty.
- Combine with psychotherapy (e.g., problem-solving therapy) for optimal outcomes.
