There are several medication options available if you have anxiety. Lexapro (escitalopram) and Xanax (alprazolam) are two different prescription drugs that can treat general anxiety as well as anxiety with depression. Lexapro is an SSRI (selective serotonin reuptake inhibitor) drug while Xanax is a benzodiazepine. Both drugs work differently from each other, although they can be used for similar mental health conditions.

What are the main differences between Lexapro vs. Xanax?

Lexapro is an FDA-approved medication that is also available as a generic. The generic name for Lexapro is escitalopram. It works by blocking the reuptake of serotonin so that there is an increased level in the brain. Serotonin is an important neurotransmitter responsible for mood and well being. Lexapro is usually taken once daily and may take a few weeks to reach maximum therapeutic potential.

Xanax is a brand name medication that is FDA approved to treat anxiety and panic disorders. The generic name for Xanax is alprazolam. It works by increasing the effects of GABA, an inhibitory molecule that can calm nerve activity in the brain. Xanax is usually taken 3 to 4 times per day for anxiety or panic attacks.

Is Lexapro vs. Xanax more effective?

Lexapro and Xanax are both effective for treating anxiety. Although benzodiazepines are not commonly used first for anxiety, some studies show that they may be more effective than SSRIs. However, benzodiazepines are usually only recommended for short-term purposes.

Sometimes SSRI drugs and benzodiazepines are prescribed for anxiety and depression. Because SSRIs may take some time to feel its full effects, a benzodiazepine may help when starting therapy with an SSRI like Lexapro. In a literature review, it was found that benzodiazepines improved control of anxiety and helped with initial anxiety when starting an SSRI.

Other case reports have found that when taken together, benzodiazepines may boost the efficacy of SSRIs. In one report, a patient taking a benzodiazepine and SSRI together experienced mania, or an excitable mood often characterized by increased energy and irrational decision making.

Treatment with Lexapro and/or Xanax is personalized to an individual’s condition and symptoms. It’s important to consult a doctor or mental healthcare professional to explore the different treatment options available.
