Objectives

Describe the incidence and costs associated with depression Discuss screening methods and diagnosis for depression Select an appropriate first-line therapy for a patient with depression

based on reported symptoms and patient comorbidities Provide pharmacologic recommendations for patients with

suboptimal responses to initial therapy Describe opportunities for pharmacists to assist in depression

Monitoring

Setting Expectations

Most side effects should subside after the first 2 weeks Counsel to take with food to avoid GI upset

Not for PRN use Adequate trial of at least 4-6 weeks before adjusting dose

Increased activity, interest, and cognition in first 1-3 weeks

Mood elevation, return of pleasure, decreased hopeless feelings, and fewer suicidal thoughts in 2-4 weeks

60-70% of patients will respond to an initial antidepressant trial 30-40% will achieve remission

Seizure disorders Bupropion and TCAs lower seizure threshold No increased risk with SSRIs/SNRIs

Obesity/Diabetes Mirtazapine and TCAs can cause/contribute to weight gain SSRIs/SNRIs associated with weight gain to a lesser extent Bupropion is weight neutral and may promote modest weight loss
