Zoloft contains sertraline hydrochloride, a prescription antidepressant belonging to the selective serotonin reuptake inhibitor (SSRI) class. Sertraline is used primarily for the treatment of depression and certain anxiety and obsession related psychiatric conditions. Health Canada currently lists Zoloft 100mg and multiple generic sertraline 100mg products as marketed prescription medications in Canada.
Sertraline works by inhibiting the neuronal reuptake of serotonin (5 hydroxytryptamine or 5 HT) within the central nervous system. By blocking the serotonin transporter, sertraline increases the availability of serotonin within the synaptic space, enhancing serotonergic signaling in neurological pathways involved in mood, anxiety, behavior, and emotional regulation.
Sertraline is considered relatively selective for serotonin reuptake. Pharmacological studies show that it has only weak effects on norepinephrine and dopamine reuptake and does not have significant direct affinity for many adrenergic, cholinergic, GABA, histamine, dopamine, or benzodiazepine receptors at clinically relevant concentrations.
In Canada, Zoloft is indicated in adults for the symptomatic treatment of depression, panic disorder with or without agoraphobia, and obsessive compulsive disorder (OCD). Its therapeutic effects generally develop progressively rather than immediately, and several weeks of continued treatment may be required before the full response becomes apparent.
For OCD, sertraline helps reduce the frequency and severity of intrusive obsessive thoughts and repetitive compulsive behaviors. In panic disorder, it can help reduce recurrent panic attacks and associated anxiety symptoms. For depression, enhanced serotonergic signaling can contribute to improvements in mood and other symptoms associated with depressive illness.

Common adverse effects associated with sertraline can include nausea, diarrhea, decreased appetite, sweating, tremor, dizziness, sleep disturbances, fatigue, and sexual dysfunction. Individual tolerability varies, and adverse effects are often most noticeable during the initial stages of treatment or following dose adjustments.
As with other SSRIs, sertraline can contribute to serotonin syndrome, particularly when combined with other serotonergic medications. Monoamine oxidase inhibitors (MAOIs) are contraindicated in combination with sertraline, and appropriate separation periods are required when switching between these medications.
SSRIs can also increase the risk of abnormal bleeding, particularly when taken alongside medications that affect blood clotting such as aspirin, NSAIDs, antiplatelet drugs, or anticoagulants. Other clinically important considerations can include low sodium levels, seizures in susceptible patients, activation of mania or hypomania in individuals with bipolar disorder, and changes in mood or behavior.
Antidepressants are also associated with an increased risk of suicidal thoughts or behavioral changes in some younger patients, particularly when treatment is initiated or adjusted. Patients should be appropriately monitored for worsening depression, significant behavioral changes, or emergence of suicidal thoughts.
Sertraline should generally not be discontinued abruptly after regular treatment. Sudden dose reduction or discontinuation may produce dizziness, irritability, anxiety, sensory disturbances, headache, sleep problems, nausea, or other discontinuation symptoms. Canadian Zoloft prescribing information recommends gradual dose reduction over several weeks whenever possible.
Zoloft (sertraline) is a prescription medication and should be used according to the directions and monitoring recommendations of a qualified healthcare professional.
