Last 1991, the pharmaceutical company Pfizer released an antidepressant drug Sertraline hydrochloride (brand names Zoloft and Lustral). As an antidepressant drug, Zoloft lies under the Selective Reuptake Inhibitor (SSRI) class of antidepressant. Disorder such as obsessive-compulsive disorder, panic attacks, social anxiety disorders (social phobia) and post-traumatic stress disorder (PTSD) are treated with Zoloft. From the aforementioned functions of Zoloft, it seems like it is such a reliable and safe antidepressant drug. However, Zoloft has had a fair share of controversies and may not be as safe as you thought it is.

An advertisement made for this product goes like this:"While the cause is unknown, depression may be related to an imbalance of natural chemicals between nerve cells in the brain. Prescription Zoloft works to correct this imbalance. You just shouldn't have to feel this way anymore."Since the drug was not supported with a successful study which could justify its efficiency as an antidepressant drug, the wordings used in the advertisement was thought to be misleading to the public. The U.S. Food and Drug Administration issued a warning to the pharmaceutical company in response to the issue.
