Citalopram (Celexa) Lexapro vs Zoloft
Table of Contents

If you are experiencing severe anxiety or depression, relief is possible with the right treatment plan. Medication is frequently used to treat anxiety disorders and depression. You may want to start by narrowing your search for a better choice of drugs. 

When it comes to prescription antidepressants, patients frequently try a variety of medications before finding the one that works best for them. Lexapro (Escitalopram) and Zoloft (Sertraline) are SSRIs (selective serotonin reuptake inhibitors) used to treat depression and other mental illnesses. SSRIs work by increasing serotonin levels in the brain, which aids in mood maintenance. Other SSRIs include fluoxetine (Prozac), paroxetine (Paxil), and citalopram ( Celexa).

The Food and Drug Administration approved Zoloft for patient use in 1999 and Lexapro in 2002, and while the medications work similarly, they differ significantly in terms of indications and side effects. Know more in detail.

What Is Lexapro?

Lexapro is the brand name of Escitalopram. Escitalopram is a first-line antidepressant used to treat depression and anxiety. You can get Lexapro online only with a doctor's prescription, as It is an SSRI class of medicine approved for acute and maintenance treatment of Major Depressive Disorder (MDD) in adolescents and adults aged 12-17 years and the acute treatment of generalized anxiety disorder (GAD) in adults.

Label Indications include:

How Does Lexapro Work?

Escitalopram binds to the presynaptic neuron's sodium-dependent serotonin transporter protein (SERT). The sodium-dependent serotonin transporter (SERT) works by re-transporting serotonin from the synaptic cleft to the presynaptic neuron. 

Escitalopram inactivates this sodium-dependent serotonin transporter protein, preventing serotonin reuptake from the synaptic cleft and thus amplifying serotonin's effect in the central nervous system.

What Is Zoloft?

The brand name of Sertraline is Zoloft. It belongs to SSRI. You can buy Zoloft online to treat conditions such as Major Depressive Disorder(MDD), obsessive-compulsive disorder (OCD), panic disorder, PTSD, premenstrual dysphoric disorder (PMDD), and social anxiety disorder. Sertraline is taken orally once a day, in the morning or evening.

Off-label indications include:

How Does Zoloft Work?

Zoloft or Sertraline is a selective serotonin reuptake inhibitor (SSRI). It works primarily by inhibiting presynaptic serotonin reuptake. Serotonin accumulates due to the inhibition of serotonin reuptake. Serotonin in the central nervous system regulates mood, personality, and wakefulness.

Lexapro Vs Zoloft: Weight Gain

Weight gain is a common side effect of antidepressant medication. While some of these medications may cause more weight gain than others, in some cases, weight gain is not directly caused by the drug.

A 2015 study published in General Hospital Psychiatry found that both Lexapro and Zoloft and other antidepressant medications could also cause weight gain. According to research, long-term use of both drugs may result in weight gain. A 2016 study published in the Journal of Clinical Medicine discovered that people taking Zoloft gained an average of 10.5 pounds over two years.

According to a 2011 study published in the International Journal of Neuropsychopharmacology, people taking Lexapro for 12 weeks gained less than a pound. In contrast, a 2007 study in Current Medical Research and Opinion found that people taking Lexapro for eight months earned an average of 4 pounds.

How Long Do Lexapro And Zoloft Take to Work?

Lexapro, like most SSRIs, can improve sleep quality, energy, and appetite within the first two weeks. However, it may take 6 to 8 weeks or longer before symptoms such as depression or decreased interest in activities begin to improve.

Zoloft (Sertraline) can take 4 to 6 weeks of regular dosing to achieve the full therapeutic effect for symptom improvement. The first effects of treatment may appear within the first 1 to 2 weeks. Some patients may require a more extended period.

In clinical trials, Zoloft was significantly more effective than a placebo in treating Major Depressive Disorder, panic disorder, PTSD, OCD, SAD, and PMDD. 

For Major Depressive Disorder and Generalized Anxiety Disorder, Lexapro was significantly more effective than a placebo in clinical studies.

According to a 2014 study published in International Clinical Psychopharmacology, Lexapro may be more effective and well-tolerated than Zoloft. Lexapro has various binding site interactions that may improve efficacy and tolerability. In another study, however, patients taking Zoloft had outcomes better than those of patients taking Lexapro in terms of adherence, drug costs, and healthcare costs.
