Final answer:
The potential side effects of Zoloft and Paxil, selective serotonin reuptake inhibitors, include sexual dysfunction and nausea.
Step-by-step explanation:
When choosing between the prescription antidepressants Zoloft and Paxil, Zoe's doctor should warn her about potential side effects such as sexual dysfunction and nausea. These drugs, known as selective serotonin reuptake inhibitors (SSRIs), work by blocking the reuptake of serotonin in the brain, which increases the levels of serotonin in the central nervous system. While they can be effective in treating depression, they can also cause certain side effects.
