Lexapro vs Buspar
Introduction
For patients with generalized anxiety disorder (GAD) or other forms of depression, certain medications that modify the levels of brain chemicals linked to mood, known as neurotransmitters, can aid in managing symptoms and stabilizing emotional lows. Lexapro and Buspar are two such drugs often prescribed for these disorders. Each impacts distinct neurotransmitters in the brain but both have been shown to have mood-stabilizing effects on patients suffering from GAD or depression. Lexapro is a selective serotonin reuptake inhibitor (SSRI), primarily affecting serotonin levels whereas Buspar is classified as an azapirone that acts as a partial agonist at 5-HT1A receptors which also affect serotonin release. Though their mechanisms differ slightly, both play critical roles in helping manage symptoms related to anxiety and depressive disorders.
What is Lexapro?
Escitalopram (the generic name for Lexapro) is an antidepressant in a group of drugs called selective serotonin reuptake inhibitors (SSRIs). It was first approved by the FDA in 2002. Lexapro affects chemicals in the brain that may become unbalanced and cause depression or anxiety, therefore it's prescribed primarily for treating depressive disorders and generalized anxiety disorder. On the other hand, Buspirone (known as BuSpar), which isn't an SSRI but rather belongs to a class of drugs known as anti-anxiety medications was introduced into clinical medicine in 1986. Unlike Lexapro, BuSpar does not affect serotonin levels to any significant degree but instead increases dopamine metabolism while reducing norepinephrine turnover. This distinction results in different side effect profiles between the two medications: whereas some people on Lexapro might experience sexual dysfunction or weight changes, those taking BuSpar are more likely to experience dizziness or headaches.
What conditions is Lexapro approved to treat?
Lexapro is approved for the treatment of various mental health disorders, including:
- Major depressive disorder (MDD), also known as unipolar depression
- Generalized anxiety disorder (GAD)
- Panic disorder On the other hand, Buspar is primarily used in the treatment of:
- Generalized anxiety disorder (GAD) It should be noted that while both drugs can be used to treat GAD, they are not interchangeable due to differences in their mechanisms of action.
How does Lexapro help with these illnesses?
Lexapro aids in managing depression and anxiety by increasing the amount of serotonin available in the brain's synapses. It works by inhibiting its reabsorption into neurons, thus allowing for sustained higher levels over time. Serotonin is a crucial neurotransmitter that functions as a messenger not only within the brain but also throughout the body. It plays pivotal roles in mood regulation, cognition, memory formation, sleep patterns, and even appetite control among other processes. The theory suggests that people suffering from depression or anxiety may have lower than normal serotonin levels; hence an increase via Lexapro can help mitigate depressive symptoms and stabilize mood swings.
On another note, Buspar (Buspirone) operates differently although it still targets serotonin receptors. Instead of preventing reabsorption like Lexapro does with SSRIs (selective serotonin reuptake inhibitors), Buspar acts as an agonist to certain serotonin receptors - meaning it stimulates these receptors to produce more serotonin naturally rather than artificially maintaining existing levels. This makes Buspar beneficial for those dealing with generalized anxiety disorder specifically because it can address underlying imbalances without necessarily causing excessive increases in overall affected neurotransmitters which could potentially lead towards dependence issues long-term if not monitored properly.
What is Buspar?
Buspar, known generically as buspirone, is an anxiolytic drug primarily used to treat generalized anxiety disorder (GAD). It functions by acting on serotonin receptors in the brain, more specifically it's a partial agonist of the 5-HT1A receptor. This means that it partially stimulates these receptors which helps to balance out levels of serotonin and reduce feelings of anxiety. Unlike Lexapro, Buspar isn't classified as an SSRI antidepressant; rather it falls under a class of medications called azapirones. The FDA approved buspirone in 1986.
As Buspar does not strongly inhibit the reuptake of serotonin like SSRIs such as Lexapro do, its side-effect profile tends to be somewhat different. For instance, Buspar may cause less sexual dysfunction—a common complaint with many SSRI medications—and generally has less withdrawal symptoms upon discontinuation due to its unique pharmacology. Yet still remains effective for managing symptoms associated with GAD and can also be beneficial for those who haven't responded well to typical SSRI treatments.
What conditions is Buspar approved to treat?
Buspar, known generically as buspirone, is approved for the treatment of:
- Generalized Anxiety Disorder (GAD), which is excessive, long-term worry and fear about everyday situations.
- Short-term relief of symptoms of anxiety. This medication isn't typically used for ongoing chronic anxiety disorders but rather short term until other treatments take effect.
How does Buspar help with these illnesses?
Buspirone, marketed under the brand name Buspar, is an anti-anxiety medication that operates by affecting neurotransmitters in the brain. Serotonin and dopamine are two chemicals associated with feelings of well-being and happiness, and they play significant roles in mental health. Low levels of these neurotransmitters have been connected to anxiety disorders. Unlike Lexapro which primarily increases serotonin availability, Buspar acts on both serotonin receptors and dopamine D2-autoreceptors but does not significantly affect norepinephrine concentrations in the brain. As such, it may be prescribed when a patient doesn't respond well to SSRI antidepressants like Lexapro or could be combined with them for a more comprehensive treatment approach.
How effective are both Lexapro and Buspar?
Escitalopram (Lexapro) and buspirone (Buspar) have both been shown to be effective in the treatment of anxiety disorders, though they act on different neurotransmitters and may therefore be prescribed under differing circumstances. Lexapro was approved by the FDA in 2002, while Buspar received its approval considerably earlier, in 1986. The efficacy of Lexapro and Buspar has been evaluated directly in an open-label trial published in 2001; this study showed similar effectiveness between these two drugs for treating generalised anxiety disorder symptoms and a comparable safety profile.
A review of meta-analysis reports on escitalopram published in 2017 revealed that it is effective at relieving symptoms of depression from the first week of treatment onward. Its side effect profile is favourable compared to many other antidepressants, including fewer sexual side effects - a common issue with SSRIs like fluoxetine or sertraline. Moreover, it's well-tolerated among various populations such as elderly patients or those suffering from comorbid conditions.
On the other hand, a systematic review conducted back in 1998 indicated that buspirone seems more effective than placebo when treating generalized anxiety disorder but appears less potent than benzodiazepines. However, unlike benzodiazepines, buspirone does not cause dependency which makes it an attractive option for long-term use. It's often considered second-line therapy after SSRIs due to slower onset action ranging from one to two weeks until improvement can be observed. This delay means that immediate relief isn't achievable using buspirone alone so short-term concomitant use with faster-acting medications might be necessary initially.
At what dose is Lexapro typically prescribed?
Oral dosages of Lexapro range from 10–20 mg/day, but research has shown that 10 mg/day is often adequate for treating generalized anxiety disorder and depression in most adults. The dosage may be increased to 20 mg/day after a few weeks if symptoms persist. For elderly patients or those with liver problems, the recommended dose is usually lower at around 10 mg per day. The maximum dosage should not exceed 20 mg/day under any circumstances.
Buspar doses typically range between 15-60mg per day, divided into two or three doses. It's usually started at a low dose such as 7.5mg twice daily, and then gradually increased every few days until reaching an effective level, depending on the individual's response and tolerance to side effects. In general practice though, it rarely exceeds more than about 45mg per day.

At what dose is Buspar typically prescribed?
Buspar treatment usually begins at a dosage of 7.5 mg twice a day, which amounts to 15 mg/day. The dose can then be increased by 5 mg every two to three days, depending on the patient's response and tolerance to the medication. The maximum recommended daily dose is 60 mg divided into several smaller doses throughout the day — this regimen may be tested if there is no significant improvement in symptoms after initial weeks of therapy at lower dosages. It's important to note that Buspar should always be administered consistently, either with or without food.

- Symptoms related to serotonin syndrome might happen; these include agitation, hallucinations, feverishness, sweating excessively or shivering uncontrollably.
Always remember that if you experience any unusual symptoms while taking Buspar (or any other medication), you should contact your healthcare provider immediately for advice.
What are the most common side effects for Buspar?
Buspar, commonly used for anxiety disorders, has a different set of potential side effects compared to Lexapro. These may include:
- Dry mouth
- Upset stomach or nausea
- Dizziness or lightheadedness
- Feeling restless or nervous
- Sleep problems such as sleepiness and insomnia
- Ringing in the ears
- Decreased concentration
- Fast heartbeat
Interestingly, unlike many other anti-anxiety medications, Buspar doesn't usually cause significant weight gain. However, it can lead to some less common but more serious side effects like confusion or hallucinations. Always consult with your healthcare provider about any concerning symptoms you experience while on medication.
Are there any potential serious side effects for Buspar?
While Buspar is generally safe and well-tolerated, it does have potential side effects that may require medical attention. These include:
- Signs of an allergic reaction: skin rash or hives; difficulty breathing; swelling of your face, lips, tongue, or throat.
- Uncontrolled movements of your body or face, tremors
- A lightheaded feeling like you might pass out
- Worsening mental health symptoms such as thoughts about suicide or hurting yourself
- Chest pain
- Shortness of breath
- Feeling unusually restless, nervous or excited
These are not all the possible side effects associated with Buspar. If any other unusual changes in mood or behavior occur after starting this medication contact your healthcare provider immediately.
Contraindications for Lexapro and Buspar?
Both Lexapro and Buspar, along with other antidepressant medications, may in some cases exacerbate symptoms of depression or anxiety. If you notice your mental health deteriorating, or if there's an increase in suicidal ideation, thoughts, or behavior while on these medications, please seek immediate medical attention.
Neither Lexapro nor Buspar should be taken if you are currently taking or have recently ceased taking monoamine oxidase (MAO) inhibitors. Always inform your physician about any medications you're on; MAOIs will require a period of approximately two weeks to be completely eliminated from the system to prevent dangerous interactions with Lexapro and Buspar.
How much do Lexapro and Buspar cost?
For the brand name versions of these drugs:
- The price for 30 tablets of Lexapro (10 mg) averages around $300, which works out to approximately $10/day.
- The price for 60 tablets of Buspar (5mg) averages about $100, working out to roughly $1.66/day.
Thus, if you're taking a typical dosage range for Lexapro (i.e., 10mg/day), then brand-name Buspar is less expensive on a per-day treatment basis. However, cost should not be the primary consideration in determining which of these drugs is right for you.
For generic versions Escitalopram (Lexapro) and Buspirone (Buspar), costs are significantly lower:
- Escitalopram is available in packs from 30 to 500 tablets with approximate costs ranging from as low as $0.14/day up to about $0.48/day depending on the quantity purchased upfront.
- Buspirone comes in packs from 15 up to hundreds of capsules with daily costs starting at just over pennies a day and not exceeding about $0.33/day if buying smaller quantities upfront.
Again prices may vary based on location, pharmacy chosen and insurance coverage but generally speaking generics offer significant savings compared to their branded counterparts.
Popularity of Lexapro and Buspar
Escitalopram, available in generic form and under the brand name Lexapro, was prescribed to about 13.5 million individuals in the United States in 2020. Accounting for nearly 28% of SSRI prescriptions and around 14% of overall antidepressant prescriptions, escitalopram remains a popular choice among healthcare providers due to its efficacy and tolerability profile.
Buspirone, also known as Buspar, is classified as an anxiolytic medication rather than an antidepressant but it's often used off-label for depression. In contrast with Lexapro’s vast usage rate, buspirone was prescribed to approximately 4 million people within the same period. This discrepancy may be attributed to varying patient health profiles or specific treatment requirements where buspirone might not always be the first-line drug option. However, it has been consistently utilized over recent years maintaining a steady prescription prevalence.
Conclusion
Both Lexapro (escitalopram) and Buspar (buspirone) have established reputations in the management of anxiety disorders, with numerous clinical studies and meta-analyses indicating their efficacy over placebo treatments. At times, these medications may be used concomitantly, although this requires careful medical supervision due to potential interactions. Their mechanisms of action differ: Lexapro primarily influences serotonin levels as a SSRI antidepressant, while Buspar acts on both serotonin and dopamine receptors.
Lexapro is often considered a first-line treatment for generalized anxiety disorder and depression; however, it can cause common side effects like sexual dysfunction or weight gain. In contrast, Buspar is usually prescribed for those who didn't respond optimally to SSRIs or wish to avoid such side-effects.
Both drugs are obtainable in generic form – a significant cost advantage especially for patients bearing out-of-pocket expenses. Both Lexapro and Buspar might necessitate an adjustment period during which effects might not immediately be noticeable.
The adverse effect profiles between the two drugs are somewhat alike - generally well-tolerated but differing slightly in nature due to their different mechanisms of action. With both medications, patients must closely track their moods particularly at the start of therapy. Immediate medical help should be sought if depressive symptoms worsen or suicidal thoughts emerge.
