– Selective serotonin reuptake inhibitors (SSRIs)
– Serotonin and norepinephrine reuptake inhibitors (SNRIs)
– Atypical antidepressants
– Tricyclic antidepressants (TCAs)

All these different classes comprise approximately thirty different varieties or brands currently present in the market. Keep in mind; each patient has unique physical characteristics implying treatment response will vary between two patients taking same medication.

What Determines How Quickly Antidepressants Take Effect?

Several factors determine how long it takes for someone using antidepressants medicine regimen before noticing improvement including:

Type Of Medication

Different medication works differently; as such, some may yield results relatively faster. On the other hand, others might require more time working their magic by manipulating hormones responsible for balancing moods since depression ensues when there is a hormonal imbalance within our brain chemistry.


Another major factor considering dosage prescribed by your clinician plays a significant role when thinking about predictably improving mental health disorders symptoms.

Unique Characteristic Physical Details

Individuals who weigh more or less have differing rates of metabolism that impact how long it takes a sedative to exit their physiological system completely. Being a factor that affects metabolism, age; thus, for an elderly individual with delicate metabolic pathways and liver/kidney function woes may take longer to see tangible positive improvements.

The severity of depression

Antidepressants should significantly improve the physical indications as well as psychological symptoms like faith in oneself /hopeless ness while diminishing resulting catastrophic anxieties.

What Antidepressant Works Fastest?

It’s not entirely true that one antidepressant works faster than another although current research suggest SSRIs work quite fast compared to other classes.


Lexapro is a selective serotonin reuptake inhibitor (SSRI) that many consider the best when it comes to quick results realization(though came into circulation more recently). By inhibiting nerve cells from absorbing all the factors responsible for mood balance(Serotonin), this drug helps ensure brain chemistry slowly reaches optimum balance henceforth reduction in depressed feelings, panic attacks, anxiety fits.

The medication could take around 1-2 weeks working upon ingestion by addressing chemical imbalances within your body after which point you needn’t increase/decrease or adjust dosage (thumbs up).


Prozac belongs in the same SSRI category as Zoloft or Citalopram tablets. Most clinicians prefer prozac over citalopram because studies have shown it makes people exhibit side effects far less frequently than most other drugs plus effective predictions times needing only two weeks instead of four weeks like some medicines.

How Long Does It Take For Antidepressants To Work In General?

This question lacks easy answers due to several crucial factors affecting each person’s experience. Nonetheless:

In broad terms, paying heed only at their permanent first few days’ evidence points before misgivings start cropping + looking out signs of worsening causes are paramount bedrock guides opening door understanding various professional opinions you may receive.

Once a clinician has prescribed the right antidepressant medication, it should take effect(slightly over two weeks) in several stages:

Weeks One & Two

At this point, only minimal indications of progress will be noticeable since the body system is still adjusting to the medication absorption process.

However, few patients mention slight boost to their energy levels and improved moods within two-three days but clinicians caution these perhaps just psychosomatic signals because at present drug not yet worked its way into neurotransporter synthesis.

Between day 5-7 mark noticeable reduction general problematic depressive symptoms as your physical characteristics start experiencing reasonable improvements from medication dosage amount taken while being absorbed more efficiently due to intake time consistency can attest.

Week Three+Markish Experiences of Additive Progress

By third week’s end, treatment acknowledges progressive positive changes- with increased measurable strides on ability dailies. Mental state represents a balance sought summing up matters up there include better sleeping habits without insomnia presence previously experienced; improved focus-bearing productive routines & renewed sense self-esteem resulting overall achievement perspective when go about daily routine – inner joy that balances out negatives overcome gradually by increasing positivity til an admirable proportion achieved.

Why Some Antidepressants Need Longer To Work Than Others?

There could be many reasons why certain medicines are slow to show results compared to others like –

Different biological targets

Different molecules target various neurotransmitters regulating mood alterations like norepinephrine; serotonin whereas another eases depression via dopamine neuro pathways because they interfere with them uniquely hence differently affect chemical processes like hormonal discharge/inhibition.

Body weight& metabolism variation between individuals where lighter bodies move around medicine quicker than obese folks necessarily.

Chronic depression cases will have altered neurochemistry– meaning some individuals require longer medication period for any changes to stick.
