2. Compliance: high risk patients3. Extreme response to side effects

4. Premature discontinuation(skepticism about meds : 62% ↑ in DC)

Head-to-Head Comparisons: SSRIs

• N= 26,000……….117 trials• Efficacy and tolerability• Among SSRIs: Sertraline (Zoloft) comes out on top• Lexapro #2 (not generic….no drug-drug interactions)
