What Is Zoloft?
Sertraline (brand name Zoloft) is a selective serotonin reuptake inhibitor (SSRI) prescribed for depression, anxiety disorders, panic disorder, and other psychiatric conditions. Most prescribed SSRI worldwide. Broadest FDA approval of any SSRI (6 indications). Mild dopamine reuptake — slightly activating. Best breastfeeding safety data of any antidepressant. Well-balanced efficacy + tolerability. Fewer drug interactions than fluoxetine/fluvoxamine/paroxetine.
At Psychiatry Telemed, sertraline is prescribed and monitored by board-certified psychiatrists who understand the nuances of SSRI pharmacology — selecting the right dose, managing side effects, monitoring drug interactions, and optimizing your treatment through consistent monthly medication management appointments.

How Zoloft Affects Neurotransmitters
How Zoloft Works
Sertraline selectively inhibits serotonin reuptake at the presynaptic transporter (SERT), increasing serotonin availability in the synaptic cleft. It has mild dopamine reuptake inhibition — unique among SSRIs — which may contribute to its activating, pro-motivational profile. It also binds sigma-1 receptors, which may add anxiolytic and pro-cognitive effects.
