What treatment options are available for individuals experiencing depression, anxiety, and low energy?

Treatment of Depression, Anxiety, and Low Energy

For individuals experiencing depression, anxiety, and low energy, cognitive behavioral therapy (CBT) should be offered as first-line treatment, with SSRIs (particularly sertraline or escitalopram) as an alternative for those without access to CBT, those preferring medication, or those with severe symptoms. 1

Initial Treatment Approach

First-Line Nonpharmacologic Options

• CBT is recommended as the primary first-line treatment for both depression and anxiety, with efficacy comparable to second-generation antidepressants 1
• CBT should be delivered by qualified therapists in individual sessions, particularly for anxiety disorders 1
• When both depression and anxiety are present (which occurs in 50-60% of cases), treat the depression first or use a unified protocol combining CBT for both conditions 1
• Additional effective nonpharmacologic options for moderate depression include:
  • Behavioral activation (BA) 1
  • Structured physical activity and exercise 1
  • Mindfulness-based stress reduction (MBSR) 1
  • Psychosocial interventions with empirically supported components (relaxation, problem solving) 1

First-Line Pharmacologic Options

When pharmacotherapy is indicated, SSRIs are the recommended first-line agents for both depression and anxiety 1

• Sertraline is particularly appropriate for patients with low energy, as it has been shown to improve energy symptoms (measured by HAM-D Retardation factor) beginning at week 3 of treatment 2
• Sertraline should be initiated at 50 mg once daily for depression 3
• For panic disorder, PTSD, and social anxiety disorder, start at 25 mg daily for one week, then increase to 50 mg daily 3
• Dose may be increased up to 200 mg/day for non-responders, with changes made no more frequently than weekly 3
• Fluoxetine has also demonstrated improvement in energy symptoms as overall depression improves, with significant reductions in retardation scores compared to placebo 2

Pharmacotherapy should be considered for:

• Patients without access to first-line psychological treatment 1
• Those expressing preference for medication 1
• Those who do not improve with psychological or behavioral management 1
• Patients with severe symptoms or psychotic features 1
• Those with history of positive response to medications 1

Patient Education and Monitoring

• Provide culturally informed and linguistically appropriate information to patients and caregivers about the commonality of depression, typical symptoms, signs of worsening, and when to contact the medical team 1
• Assess treatment response regularly using standardized instruments at 4 and 8 weeks 1, 4
• If symptoms are stable or worsening after 8 weeks despite good adherence, reevaluate and adjust the treatment plan 1, 4
• Monitor for symptom relief, side effects, and patient satisfaction when using pharmacotherapy 1, 4

Second-Line Treatment Strategies

If initial treatment with an SSRI fails to achieve remission after an adequate trial, both switching and augmentation strategies show similar efficacy 1

Switch Strategies

• No significant differences exist between switching to different SSRIs (escitalopram, sertraline) or other second-generation antidepressants (bupropion SR, venlafaxine, duloxetine, mirtazapine) 1
• Switching to cognitive therapy shows similar efficacy to pharmacologic switches 1

Augmentation Strategies

• Augmenting the initial SSRI with bupropion SR, buspirone, or cognitive therapy shows comparable efficacy 1
• Bupropion SR augmentation has lower discontinuation rates due to adverse events (12.5%) compared to buspirone (20.6%) 1
• Augmenting with mirtazapine shows similar efficacy to switching to mirtazapine 1

Safety Considerations

Common Adverse Effects of SSRIs

• Gastrointestinal disturbances, headache, nausea 3, 5
• Sleep disturbances (insomnia or sedation) 3, 5
• Sexual dysfunction 3, 5
• Weight changes 3, 5

Serious Risks Requiring Monitoring

• Increased suicidal thoughts or actions in children, teenagers, and young adults, especially in first few months or with dose changes 3
• Serotonin syndrome (agitation, hallucinations, coordination problems, racing heartbeat, fever, muscle rigidity) 3
• Abnormal bleeding, especially with concurrent use of NSAIDs, aspirin, or warfarin 3
• Hyponatremia, particularly in elderly patients 3
• Manic episodes (increased energy, decreased sleep, racing thoughts, reckless behavior) 3

Critical Warnings

• Do not combine SSRIs with MAOIs; allow 2-week washout period between medications 3
• Do not stop SSRIs abruptly; taper to avoid discontinuation syndrome (anxiety, irritability, dizziness, electric shock sensations) 3

Treatment Duration

• Acute episodes of major depression require several months or longer of sustained pharmacologic therapy beyond initial response 1, 3
• Sertraline efficacy has been demonstrated for maintenance treatment up to 44 weeks for depression and 28 weeks for PTSD 3
• Patients should be periodically reassessed to determine need for continued maintenance treatment 3

Comparative Effectiveness Notes

While fluoxetine and sertraline are both effective SSRIs, sertraline may have advantages in efficacy compared to fluoxetine based on head-to-head comparisons 6. Sertraline also demonstrates low potential for drug interactions as it is not a potent inhibitor of cytochrome P450 enzymes, unlike fluoxetine and paroxetine 7. For patients specifically concerned about low energy, sertraline's demonstrated improvement in retardation symptoms makes it a particularly appropriate choice 2.
