What is Zoloft? 

Zoloft is the brand name for the medication Sertraline. Sertraline belongs to the drug class selective serotonin reuptake inhibitors (SSRIs). It’s an FDA-approved medication for the management of depression and anxiety attacks. 

As their name indicates, SSRIs work by prolonging the stay-of-happy hormone serotonin in the brain and blocking the reabsorption of the neurotransmitter “Serotonin”. By doing so, serotonin helps manage mood, anxiety, and panic attacks that occur in depression. 

Zoloft stands out as a safer choice for managing depression and anxiety compared to other drug classes, such as benzodiazepines, because it doesn’t carry the risk of dependency. Unlike benzodiazepines, Zoloft doesn’t lead to a reliance on the medication to function normally. Other than its dependency, it shows comparatively better tolerability and patient compliance.
