In general, Lexapro has fewer side effects than
Zoloft and Luvox.
Zoloft causes more nausea, and sexual dysfunction. Sexual dysfunction is also common with Luvox, but less than that caused by Zoloft.
Withdrawal symptoms are highest with Zoloft and Luvox. However, due to lower protein binding in blood, Luvox gets cleared from the body pretty fast compared to Lexapro and Zoloft, so withdrawal symptoms can abate faster.
