Despite the widespread use of antidepressants in modern psychiatric practice, misconceptions and stigma continue to shape patient and professional attitudes alike. These myths not only lead to treatment hesitancy, missed diagnoses, and suboptimal outcomes but also complicate clinical decision-making for young psychiatrists navigating the realities of medication management. In an era of instant online information, it is more important than ever to counter misinformation with current evidence, clear communication, and compassionate care. This section debunks common myths about antidepressant medications—grounding each point in scientific fact so that psychiatrists can confidently address patient concerns and support informed mental health care.
Myth: Antidepressants work by simply increasing serotonin levels.
Fact: While the initial discovery of selective serotonin reuptake inhibitors (SSRIs) in the 1980s centred on the serotonin hypothesis of depression, current evidence demonstrates that antidepressant efficacy extends well beyond monoamine modulation. Antidepressants influence multiple interconnected neurotransmitter systems—serotonin, norepinephrine, dopamine, glutamate, and GABA—creating cascading effects throughout neural circuits. More importantly, the therapeutic mechanism involves promoting neuroplasticity and neurogenesis—the brain’s capacity to reorganise itself and generate new neurons, particularly in the hippocampus. These neurobiological changes unfold gradually over 4-6 weeks, explaining the delayed therapeutic onset despite immediate neurochemical effects.
Myth: Antidepressants will change your personality or prevent you from feeling emotions.
Fact: Depression itself profoundly alters personality. Untreated Major Depressive Disorder dampens emotional reactivity, reduces social engagement, impairs decision-making capacity, and fundamentally narrows the range of experienced emotions. Patients frequently describe feeling “numb” or “disconnected” long before medications begin. Effective antidepressant treatment restores baseline personality functioning rather than artificially modifying it—patients recover their authentic emotional range, spontaneity, and interpersonal warmth. However, a legitimate and recognised concern exists: emotional blunting or flattening as an adverse effect. This distinct phenomenon involves genuine medication-induced dampening of emotional intensity. Critically, this differs from depressive numbing—patients on antidepressants often describe maintaining cognitive awareness of situations that should trigger emotions while experiencing diminished affective response. This side effect warrants acknowledgement and clinical intervention—dose reduction, medication switching, or augmentation strategies may restore emotional responsiveness while maintaining antidepressant benefits.
Myth: Antidepressants are addictive.
Fact: Addiction involves compulsive substance-seeking behaviour, craving, and continued use despite harmful consequences—characterised by reward-seeking driven through dopaminergic pathways. Dependence refers to physiological adaptation to a medication, where discontinuation produces withdrawal symptoms.
Antidepressants do not produce addiction because they create no euphoria, do not activate reward circuitry, and generate no craving behaviour. Patients do not escalate doses seeking greater effects, do not misuse medications despite negative consequences, and do not engage in drug-seeking behaviour—all hallmarks of addiction.
Discontinuation syndrome, however, represents a genuine phenomenon requiring clinical recognition. Abrupt cessation or rapid tapering of SSRIs, SNRIs, and some tricyclic antidepressants produces withdrawal symptoms including dizziness, paraesthesia, gastrointestinal upset, and mood destabilisation depending on medication and tapering speed. This physiological dependence necessitates gradual, supervised tapering over weeks to months.
Myth: Antidepressants cause inevitable weight gain.
Fact: Weight gain is sometimes seen with long-term antidepressant use, but it is not universal and does not affect every patient, nor is it caused by all medications. Notably, bupropion is often weight-neutral or associated with mild weight loss. Depression itself impacts appetite and energy metabolism, which can confound the relationship between medication and weight. Lifestyle factors also contribute – maintaining balanced nutrition and regular physical activity during treatment can mitigate risk.
Myth: Antidepressants always cause sexual dysfunction.
Fact: Sexual dysfunction is a well-documented side effect of some antidepressants, but it does not affect all patients and is often reversible. The prevalence varies by medication, and bupropion and agomelatine have risks similar to those of a placebo. Importantly, untreated depression alone can cause sexual problems, so improvement is sometimes seen with effective treatment. If difficulties persist, clinicians can offer dose changes, consider switching medications, or add strategies to alleviate symptoms. In fact, SSRIs are indicated for premature ejaculation.
Myth: Antidepressants are only prescribed for depression.
Fact: Antidepressants are widely prescribed for a variety of psychiatric and medical conditions beyond depressive disorders, reflecting their broad therapeutic utility. They are also indicated for Obsessive Compulsive Disorder, Anxiety Disorders, Insomnia, Chronic Pain Syndromes, Eating Disorders, Enuresis and certain dermatological and inflammatory conditions.

Instead of generic use of the term ‘antidepressant’, let us use terms like SSRI, Tricyclic, SNRI, MAOI etcfor each myth.
