What is the first-line treatment for depression in a patient over 65 with a bleeding disorder?

First-Line Treatment for Depression in Patients Over 65 with Bleeding Disorders

For patients over 65 with depression and a bleeding disorder, psychotherapeutic approaches such as cognitive behavioral therapy (CBT) should be used as first-line treatment rather than SSRIs due to the increased risk of upper gastrointestinal bleeding associated with SSRIs in this population. 1

Treatment Algorithm

First-Line Treatment Options:

1. Psychotherapeutic approaches:
   • Cognitive Behavioral Therapy (CBT)
   • Brief psychosocial counseling
   • Staff-assisted depression care supports

Second-Line Medication Options (if psychotherapy is insufficient):

1. Bupropion - Has minimal effect on serotonin reuptake and lower bleeding risk
2. Mirtazapine - Has different mechanism of action than SSRIs with lower bleeding risk

Rationale for Avoiding SSRIs as First-Line

The U.S. Preventive Services Task Force specifically recommends that "for adults 65 years or older, clinicians may want to select a psychotherapeutic approach or medications other than SSRIs because of the increased risk for UGI bleeding associated with the use of SSRIs." 1

This recommendation is particularly important for patients with pre-existing bleeding disorders, as:

• SSRIs inhibit serotonin reuptake into platelets, which can impair platelet aggregation
• Medications with a moderate to high degree of serotonin reuptake inhibition pose the greatest risk for bleeding 1, 2
• The most frequent hemostatic abnormalities with SSRIs are decreased platelet aggregability and activity, and prolongation of bleeding time 2

Efficacy Considerations

Both psychotherapeutic approaches and antidepressants are effective in treating depression in older adults 1. The American College of Physicians guidelines note that second-generation antidepressants are equally effective among different age groups, including the elderly 1.

If Medication Becomes Necessary

If psychotherapy alone is insufficient and medication is required:

• Bupropion may be considered as it has minimal effect on serotonin reuptake and therefore less impact on platelet function
• Mirtazapine is another alternative with a different mechanism of action than SSRIs
• Avoid tricyclic antidepressants (TCAs) in the elderly due to their potential to worsen glucose control, increase carbohydrate cravings, and risk of hypoglycemia unawareness 3, 4

Monitoring Recommendations

If medication treatment is initiated:

• Use standardized depression measures (e.g., PHQ-9) every 2-4 weeks 3
• Monitor for any signs of abnormal bleeding
• Platelet dysfunction, coagulation disorder, and von Willebrand disease should be sought in any case of abnormal bleeding during treatment 2

Important Cautions

• The risk for bleeding is highest in the first month of treatment with serotonergic antidepressants 5
• Concurrent use of SSRIs with NSAIDs or low-dose aspirin significantly increases bleeding risk 1
• For patients with a high risk of bleeding who must take an antidepressant, consider medications that do not, or less potently, inhibit serotonin reuptake 5

By prioritizing psychotherapeutic approaches for older patients with bleeding disorders, clinicians can effectively treat depression while minimizing the risk of potentially serious bleeding complications.
