Medications are sometimes necessary while dealing with overwhelming mental health conditions like Anxiety disorders or depression that cause problems in day-to-day living. Depression is a common disorder worldwide, with an estimated 3.8% of the population affected, including 5.0% among adults and 5.7% among adults older than 60. Its prevalence is majorly among adult females (10.5%) compared to males (6.2%).

To cope with such major depressive disorder, Wellbutrin and Lexapro are two medications many healthcare physicians prescribe.

Lexapro and Wellbutrin are effective at treating Anxiety & depression by acting on different neurotransmitters. While Lexapro increases available serotonin, Wellbutrin increases the availability of dopamine and norepinephrine to mediate mood changes.

Are Wellbutrin And Lexapro The Same?

Lexapro and Wellbutrin are antidepressants used to treat major depressive disorder & Anxiety disorders like panic attacks or social phobia. Lexapro is indicated for treating generalized Anxiety disorder, while Wellbutrin can be taken for seasonal affective disorder (SAD).

Both medications belong to different drug classes. Lexapro is an SSRI, while Wellbutrin belongs to the aminoketone class of drugs.

Although Lexapro has been approved for depression and generalized Anxiety disorder (GAD) by the Food and Drug Administration (FDA), it is also prescribed for many other conditions. Studies have shown it is also effective in mood and Anxiety disorders. 

Dosage Instructions For Wellbutrin And Lexapro:

For Lexapro:

Lexapro is usually started at 10 mg once daily in adults or adolescents but can be increased to 20mg after 1 week.

For those suffering from depression, 20 mg may not be more effective than 10 mg daily. For treatment for generalized Anxiety disorder, the dosage is 10mg once per day.

For depression, the recommended dose is 100 mg 3 times daily (300mg/day) with a maximum of 450mg per day. The initial dosage is 100 mg twice daily.

The initial dose of the sustained-release tablets is 150 mg daily; the target dose is 150 mg twice a day, and the maximum dosage should not exceed 200mg per dosage.

The initial dose of extended-release tablets is 150 mg daily, with a target dose of 300 mg and a maximum dosage of 450mg. Extended-release pills can only be taken once daily.

Conditions Treated By Wellbutrin And Lexapro

In treating Major Depressive Disorder (MDD), Wellbutrin and Lexapro help alleviate prolonged feelings of low moods and lack of energy and affect everyday behaviors. Unlike other antidepressants, which can take up to two weeks or more, MDAs start working within a week after administration & thus, patients will feel better in no time!

Lexapro is also indicated in the treatment of generalized Anxiety disorder (GAD). Individuals with GAD are known to fret about various issues for extended periods.

Bupropion, the active ingredient in Wellbutrin, is understood to have a unique indication for smoking cessation. Patients taking bupropion are more likely to be able to achieve smoking cessation.

Wellbutrin and Lexapro are used off-label in various psychological disorders resembling depression or Anxiety. Your healthcare professional can help you diagnose your disorder and determine which treatment option is best for you.

Which Drug Is More Effective: Wellbutrin Or Lexapro?

In a study, researchers compared Wellbutrin and Lexapro as singular therapies for major depressive disorder (MDD). The trial also evaluated the prevalence of adverse sexual side effects in these two medications. The results found that both drugs are great for combating depressive symptoms. However, the study concluded Wellbutrin leads to less sexual dysfunction than Lexapro.

Wellbutrin and Lexapro affect different neurotransmitters, so they are often used together. Clinical trials found that using both Wellbutrin and Lexapro leads to significantly higher response rates than standard monotherapy with SSRIs.

Significant Differences Between Wellbutrin And Lexapro:

Lexapro and Wellbutrin are antidepressants prescribed to treat major depression. Lexapro is used for Anxiety in adults, while Wellbutrin belongs to the aminoketone drug class.

Wellbutrin is available in 3 tablet forms. The immediate-release tablets are 75 mg and 100 mg, and the sustained-release tablets come in 100mg, 150mg, and 200mg; the extended-release pill, which can be taken once every 24 hours, comes as 150 or 300 milligrams (MG).

Lexapro is available as an oral tablet in strengths of 5 mg, 10 mg, and 20mg. It's also an oral solution with a concentration of 5 mg/5 ml.

Wellbutrin was previously marketed under the brand name Zyban. The active ingredient, bupropion, is approved for smoking cessation as it leaves higher levels of dopamine and norepinephrine freely available. It contributes to better moods, calms Anxiety & helps motivate a person not to smoke again.

Lexapro is an antidepressant that belongs to the selective serotonin reuptake inhibitors (SSRIs) group. Lexapro works by blocking the serotonin reuptake at the neuronal membrane transport pump, effectively leaving more free serotonin in the neuron synapse.
