    With all the different depression and anxiety medications on the market, it can be hard to know which drug is which. Lexapro and Zoloft are two of the more commonly prescribed medications for mood disorders such as depression.

    These drugs are a type of antidepressant called selective serotonin reuptake inhibitors (SSRIs). SSRIs work by increasing levels of serotonin, a substance in your brain that helps maintain your mood. Read on to learn more about similarities and differences between Lexapro and Zoloft.
