From the Guidelines
For a 23-year-old male with severe depression, selective serotonin reuptake inhibitors (SSRIs) such as sertraline or escitalopram are recommended as the first-line treatment due to their favorable safety profile and efficacy. According to the American College of Physicians guideline 1, second-generation antidepressants, including SSRIs, should be chosen based on adverse effect profiles, cost, and patient preferences. The guideline also states that existing evidence does not justify the choice of any second-generation antidepressant over another on the basis of greater efficacy and effectiveness.
Key Considerations
- Sertraline (Zoloft) starting at 50mg daily and gradually increasing to 100-200mg daily, or escitalopram (Lexapro) starting at 10mg daily and potentially increasing to 20mg daily, would be good options 1.
- These medications usually require 4-6 weeks to achieve full therapeutic effect, though some improvement may be noticed earlier.
- Side effects can include initial nausea, headache, insomnia, or sexual dysfunction, but these often improve with time.
- For severe depression, combining medication with psychotherapy such as cognitive behavioral therapy (CBT) is more effective than either treatment alone.
- Regular follow-up is essential to monitor response and side effects, particularly watching for worsening depression or suicidal thoughts in the first few weeks of treatment, as recommended by the American College of Physicians guideline 1.
- If the patient doesn't respond adequately after 6-8 weeks at an optimal dose, switching to another SSRI or a different class like SNRIs (venlafaxine or duloxetine) would be appropriate, considering the patient's preferences, adverse effect profiles, and cost 1.

From the Research
Antidepressant Options for Severe Depression
- The patient's severe depression can be treated with various antidepressants, including selective serotonin reuptake inhibitors (SSRIs) 2, 3, 4, 5, 6.
- SSRIs are a commonly prescribed class of antidepressants due to their efficacy, tolerability, and safety in overdose 4.
SSRI Dosage
- The optimal dose of sertraline for treating depression is 50 mg/day, which can be increased in 50 mg/day increments up to a maximum of 200 mg/day if necessary 2.
- A systematic review and dose-response meta-analysis found that the lower range of licensed doses (20-40 mg fluoxetine equivalents) achieves the optimal balance between efficacy, tolerability, and acceptability in the acute treatment of major depression 3.
Commonly Used SSRIs
- Fluoxetine, sertraline, paroxetine, fluvoxamine, and citalopram are examples of SSRIs that are effective in treating major depression 4.
- Each SSRI has a unique pharmacokinetic and pharmacodynamic profile, as well as a distinct side effect profile 5, 6.
Considerations for Young Adults
- When prescribing SSRIs to young adults (18-24 years old), it is essential to consider the potential increased risk of suicidality and conduct a thorough risk-benefit analysis 5.
