What is Lexapro (Escitalopram)?
Lexapro (escitalopram) is an SSRI antidepressant that works by increasing serotonin levels in the brain to regulate mood and reduce anxiety over time. It is used for long-term treatment of conditions like Generalized Anxiety Disorder (GAD) and Major Depressive Disorder (MDD). Lexapro is taken daily, with full effects typically seen after 4 to 6 weeks. It has a low risk of abuse, but withdrawal can occur if stopped abruptly.
What is Xanax (Alprazolam)?
Xanax (alprazolam) is a benzodiazepine that acts as a CNS depressant. It enhances GABA's inhibitory effects in the brain, leading to rapid sedation and anxiety reduction. Xanax is prescribed for short-term relief of acute anxiety and panic attacks, with effects noticeable within minutes to an hour. Due to its high potential for dependence and addiction, Xanax is not recommended for long-term, daily use.
Lexapro vs. Xanax Comparison Table
| Feature | Lexapro (Escitalopram) | Xanax (Alprazolam) |
|---|---|---|
| Drug Class | Selective Serotonin Reuptake Inhibitor (SSRI) | Benzodiazepine |
| Primary Function | Increases serotonin levels over time for mood regulation | Enhances GABA's calming effect for immediate CNS depression |
| Onset of Action | Gradual (weeks) | Rapid (minutes to 1 hour) |
| Therapeutic Use | Long-term management of GAD and MDD | Short-term relief for acute anxiety and panic attacks |
| Dependence Risk | Low risk of addiction; tapering needed to avoid withdrawal | High risk of physical dependence and addiction, even with prescribed use |
| Common Side Effects | Nausea, insomnia, sexual dysfunction, diarrhea | Drowsiness, sedation, memory problems, dizziness |
| Withdrawal Symptoms | Mood changes, dizziness, tingling, fatigue | Anxiety, insomnia, seizures (in severe cases) |
Side Effects and Withdrawal
Both medications can cause CNS-related side effects. Xanax frequently causes significant sedation, while Lexapro may cause gastrointestinal issues and sexual dysfunction. Abrupt discontinuation of either medication can cause withdrawal, requiring tapering under medical supervision. Xanax withdrawal can be particularly severe, including seizure risk.
Can Lexapro and Xanax Be Taken Together?
A doctor may prescribe Lexapro and Xanax together under close supervision. This is sometimes done at the start of Lexapro treatment to manage immediate anxiety symptoms while waiting for Lexapro to become effective. Once Lexapro is working, Xanax is typically tapered off. Combining these medications or adjusting doses without a doctor's guidance is dangerous due to increased side effects and risks of addiction and overdose.
Conclusion: Is Lexapro like Xanax? The Verdict
Lexapro and Xanax are not alike, despite both treating anxiety. Lexapro (an SSRI) is for long-term treatment of underlying imbalances via serotonin regulation, while Xanax (a benzodiazepine) provides rapid, short-term sedation by enhancing GABA's effect. Lexapro is a long-term solution, whereas Xanax is for acute relief. The appropriate choice depends on the individual's symptoms and must be decided in consultation with a healthcare provider.

Key Differences Between Lexapro and Xanax
- Drug Class: Lexapro is an SSRI, while Xanax is a benzodiazepine, meaning they act on different brain chemicals.
- Treatment Duration: Lexapro is a long-term maintenance medication, whereas Xanax is prescribed for short-term, immediate relief.
- Mechanism of Action: Lexapro gradually increases serotonin levels, while Xanax quickly enhances the calming effect of GABA.
- Dependence Potential: Xanax carries a high risk of physical dependence and addiction, which is not the case with Lexapro.
- Withdrawal Risks: Withdrawal from Xanax can be more severe and dangerous, potentially causing seizures, compared to Lexapro's withdrawal symptoms.
- Side Effects: Xanax is more likely to cause sedation, while Lexapro is more associated with gastrointestinal and sexual side effects.
Lists of Common Side Effects
Common side effects for Lexapro include nausea, diarrhea, insomnia, sexual dysfunction, dry mouth, increased sweating, and fatigue. Common side effects for Xanax include drowsiness, sedation, memory problems, dizziness, poor balance or coordination, slurred speech, fatigue, and constipation.
When Are They Used for Anxiety?
Lexapro is typically the first choice for chronic, generalized anxiety due to its long-term effect on chemical imbalances. Xanax is used for acute, intense anxiety or panic attacks, providing quick relief when needed. Healthcare providers aim for long-term stability with medications like Lexapro and limit the use of potentially addictive benzodiazepines like Xanax.
