Sertraline hydrochloride (Zoloft) is an orally administered antidepressant of the selective serotonin reuptake inhibitor (SSRI) type. Sertraline is used medically mainly to treat the symptoms of depression and anxiety. It has also been prescribed for the treatment of obsessive-compulsive disorder, post-traumatic stress disorder, premenstrual dysphoric disorder, panic disorder, and bipolar disorder. It was first approved by the FDA in 1991.

Sertraline is an odorless, white, sparingly soluble crystalline solid. The minimum effective dose is 50 mg per day, but lower doses may be used in the initial weeks of treatment to acclimate the patient's body, especially the liver, to the drug and to minimize the severity of any side effects. Patients who do not experience relief of symptoms at 50 mg a day may have their dose increased, up to 200 mg a day.

One property of sertraline is that it appears to be also a minor inhibitor of dopamine reuptake. At higher dosages (300 mg/day), sertraline inhibits the reuptake of dopamine as well as serotonin.

Sertraline can have a number of adverse effects, including insomnia, asthenia, gastrointestinal complaints, tremors, confusion, dizziness, anorgasmia, and decreased libido; it can induce mania or hypomania in around 0.5% of patients. It has also been known to cause minor weight loss. It is contraindicated in individuals taking MAOIs or undergoing electroconvulsive therapy.
