Anti-Depressants
This category groups medications used to treat depression and anxiety disorders, including SSRIs (such as sertraline) and other classes. Treatment effects develop gradually over weeks and require medical supervision.
Overview
Antidepressants are a heterogeneous group of medications used to treat depression, anxiety disorders, OCD, PTSD and other psychiatric conditions. They are not stimulants and do not produce immediate effects: clinical benefit typically develops over 4 to 6 weeks of continuous treatment. The most prescribed class today is selective serotonin reuptake inhibitors (SSRIs), which include sertraline (Zoloft), fluoxetine, escitalopram and others. Other classes include SNRIs, tricyclics, MAOIs and atypicals.
Common treatments
Selective serotonin reuptake inhibitors (SSRIs) are the most common first-line option for depression and anxiety due to their generally favourable side effect profile. SNRIs (serotonin-norepinephrine reuptake inhibitors) such as venlafaxine and duloxetine are alternatives, particularly when SSRIs do not produce sufficient response. Older classes (tricyclic antidepressants, MAOIs) remain options in selected cases. Adjunct strategies include cognitive-behavioral therapy, exercise, and treatment of comorbid medical conditions.
When to consult
Persistent low mood, loss of interest, anxiety or sleep disturbance lasting more than two weeks should be evaluated by a healthcare provider. According to clinical guidelines, the initial assessment explores severity, suicidality risk, prior treatment response, comorbid medical conditions and substance use. Treatment is most effective when pharmacological and psychological approaches are combined. Self-medication with online-only purchases bypasses essential safety review and is strongly discouraged.

Frequently asked questions
How do antidepressants work? ▾
Most modern antidepressants modulate the levels or activity of one or more neurotransmitters in the brain — serotonin, norepinephrine and to a lesser extent dopamine. SSRIs increase serotonin levels by blocking its reuptake; SNRIs do the same for both serotonin and norepinephrine. The exact link between these biochemical changes and clinical mood improvement remains incompletely understood, but the consistent observation is that several weeks of treatment are needed for full effect.
Are antidepressants addictive? ▾
Most modern antidepressants — SSRIs, SNRIs and atypical agents — are not considered addictive in the traditional sense. However, abrupt discontinuation after weeks of regular use can cause discontinuation syndrome with dizziness, sleep disturbance, sensory changes and flu-like symptoms. According to clinical guidelines, antidepressants should be tapered gradually rather than stopped suddenly, even though this is sometimes confused with withdrawal from a substance of abuse.
How long should I take an antidepressant? ▾
Treatment duration depends on the diagnosis, severity and history. According to current guidelines, a first episode of major depression typically requires at least 6 to 12 months of treatment after symptom remission. Recurrent or severe cases may require longer-term or indefinite treatment. The decision to continue or stop is made jointly with the prescribing physician, who considers risk of relapse, side effect tolerance and individual circumstances.
Will an antidepressant change my personality? ▾
Antidepressants are intended to address symptoms of depression or anxiety, not to alter underlying personality. Most patients describe the effect as 'feeling like myself again' rather than feeling different. However, some patients report emotional blunting — a reduced intensity of both negative and positive emotions — particularly with SSRIs at higher doses. According to clinical guidelines, this should be discussed with the prescribing physician if it occurs and persists.
Can I buy antidepressants online without a prescription? ▾
Antidepressants are prescription-only medicines in most regulated jurisdictions. Online-only sales without a clinician evaluation bypass essential safety screening for suicidality risk, drug interactions and medical comorbidities. Counterfeit antidepressants from unverified sources may contain incorrect doses or undeclared ingredients, which is particularly dangerous given the slow response time and risk of treatment failure. According to regulators, only purchase through licensed pharmacies.
