Lexapro vs Lyrica
Introduction
For patients dealing with anxiety disorders or different types of depression, certain drugs that modify the levels of neurotransmitters in the brain can help manage symptoms and stabilize mood. Lexapro and Lyrica are two such medications commonly prescribed for these conditions. These drugs influence different neurotransmitters but both contribute to managing anxiety and depressive symptoms.
Lexapro is a selective serotonin reuptake inhibitor (SSRI), primarily affecting serotonin levels in the brain, which is instrumental in regulating mood. On the other hand, Lyrica is classified as an anticonvulsant drug used mainly to treat nerve pain and fibromyalgia but also has significant effects on generalized anxiety disorder due to its ability to bind to specific areas in the brain that reduce nerve signals hence decreasing feelings of fear or stress.
What is Lexapro?
Escitalopram (the generic name for Lexapro) is a prominent drug from the SSRI class of antidepressants, which played a significant role in the evolution beyond the initial generation of antidepressant drugs known as tricyclic antidepressants (TCAs). Escitalopram was first approved by the FDA in 2002. Lexapro functions by increasing free serotonin levels through inhibiting its reabsorption, effectively maintaining it within the brain for extended periods. It is commonly prescribed to manage various forms of depression and anxiety disorders. Like Prozac, Lexapro has selective influence on serotonin with minimal impact on dopamine and norepinephrine neurotransmitters, resulting in fewer side effects than other antidepressants that have stronger impacts on these two neurochemicals.
On another note, Pregabalin (the generic name for Lyrica), although not an antidepressant like Lexapro or Prozac, serves a different purpose entirely. Approved by FDA in 2004,Lyrica belongs to a class of medicines called anticonvulsants and primarily works against seizures,epilepsy,fibromyalgia,and nerve pain due to diabetes or shingles.It operates mainly by slowing down impulses in the brain that cause seizures while also affecting chemicals involved with pain signals.
What conditions is Lexapro approved to treat?
Lexapro is approved for the treatment of various mental health disorders:
- Generalized anxiety disorder (GAD)
- Major depressive disorder (MDD)
Lyrica, on the other hand, is indicated for different conditions:
- Neuropathic pain associated with diabetic peripheral neuropathy
- Postherpetic neuralgia (pain after healing of shingles rash)
- Fibromyalgia
- Neuropathic pain associated with spinal cord injury
- As an adjunctive therapy in adults with partial onset seizures.
How does Lexapro help with these illnesses?
Lexapro aids in managing depression and anxiety by increasing the amount of serotonin available in the synapses of the brain, similar to Prozac. It does so by inhibiting its reuptake into the presynaptic cell, which increases the amount of serotonin present in the synaptic cleft that can bind to receptors on the postsynaptic neuron. Serotonin is a neurotransmitter that plays a crucial role in mood regulation, cognition, memory, sleep patterns among other things. It's believed that individuals suffering from depression have relatively lower levels of serotonin. Therefore, Lexapro can help mitigate depressive symptoms by elevating these levels.
On another hand, Lyrica works differently; it doesn't target serotonin or any monoamine neurotransmitters. Instead, it binds to a specific site (alpha-2-delta) on voltage-gated calcium channels within neurons in our central nervous system (CNS). This diminishes pathologic neural activity and reduces release of certain neurotransmitters such as glutamate - thereby producing analgesic and anticonvulsant effects beneficial for conditions like fibromyalgia or neuropathic pain disorders.
What is Lyrica?
Lyrica, or pregabalin as it is also known, is an anti-epileptic drug that works by slowing down impulses in the brain that can cause seizures. It's also used to treat fibromyalgia and nerve pain caused by diabetes (diabetic neuropathy) or herpes zoster (post-herpetic neuralgia). Pregabalin has a unique mechanism of action; it binds strongly to a specific site (alpha2-delta site) on voltage-gated calcium channels in central nervous system tissues. Although how this activity translates into the therapeutic effects of pregabalin is unknown, it does not inhibit dopamine reuptake nor act on serotonin receptors. This means its side-effect profile can be different from drugs like Lexapro which are selective serotonin reuptake inhibitors (SSRIs). For instance, Lyrica has less potential for weight gain and sexual dysfunction - common side effects associated with SSRIs such as Lexapro. However, dizziness and sleepiness are more common with Lyrica use than with SSRIs. It was approved by the FDA in 2004 and provides another option for patients who may not respond well to other types of medications.
What conditions is Lyrica approved to treat?
Lyrica, also known by its generic name pregabalin, is commonly prescribed for the treatment of:
- Neuropathic pain associated with diabetic peripheral neuropathy
- Postherpetic neuralgia (pain following shingles)
- Fibromyalgia
- Partial onset seizures in adults with epilepsy who take one or more drugs for seizures
- Chronic pain caused by spinal cord injury
How does Lyrica help with these illnesses?
Gamma-aminobutyric acid (GABA) is a neurotransmitter that plays key roles in managing anxiety, sleep, and sensations of pain among other processes in the body. It works by inhibiting nerve transmission in the brain, calming nervous activity. Lyrica functions by binding to specific subunits of voltage-gated calcium channels within the CNS, which leads to decreased release of certain neurotransmitters including glutamate, norepinephrine and substance P. Its therapeutic effect comes from its ability to slow down impulses in the brain that cause seizures and reduce neuronal excitability leading to analgesic effects. This function makes it an effective medication for treating fibromyalgia pain, neuropathic pain and postherpetic neuralgia apart from being an antiepileptic or anticonvulsant drug.
In contrast with Lexapro—which is primarily used as a treatment for depression due to its action on serotonin levels—Lyrica does not significantly affect these levels but instead targets GABA pathways. Consequently, it's often prescribed when patients are dealing with conditions that respond well to increased GABA activity such as seizure disorders or various types of chronic pain syndromes while also having potential benefits for those suffering from generalized anxiety disorder.
How effective are both Lexapro and Lyrica?
Both escitalopram (Lexapro) and pregabalin (Lyrica) have established histories of success in treating patients with anxiety disorders, though they were approved by the FDA several years apart. Since they act on different neurotransmitters, they may be prescribed under different circumstances. The effectiveness of escitalopram and pregabalin in alleviating symptoms associated with anxiety was directly studied in a double-blind clinical trial in 2006; the two drugs exhibited similar efficacy in managing these symptoms as well as similar safety profiles.
A review conducted later on demonstrated that escitalopram is effective at reducing symptoms related to panic disorder, generalized anxiety disorder and social phobia starting within the first week or two treatment. Its side effect profile is generally favorable over many other antidepressants, making it a popular choice for healthcare providers when prescribing medication for these conditions.
Meanwhile, a 2012 review indicated that pregabalin appears more effective than placebo at treating cases of generalised anxiety disorder. It also seems to be similarly efficacious compared to other common anti-anxiety medications. Nonetheless, its use typically comes after SSRIs or benzodiazepines are considered due to their longer-standing history of use and larger body of research supporting their safety and efficacy.
While each drug has beneficial attributes which make them useful choices for certain patients depending on individual needs and tolerances - such as Lexapro's lower likelihood to cause weight gain compared to some alternatives or Lyrica's utility for those who failed SSRI/SNRI therapy - both have been shown overall capable options when combating various types of anxiety disorders.
At what dose is Lexapro typically prescribed?
Oral dosages of Lexapro typically range between 10–20 mg/day. However, studies have shown that a dose of 10 mg/day is generally sufficient for treating depression and generalized anxiety disorder in most adults. Adolescents aged 12 to 17 may be started on a dose of 10 mg/day as well. For both adults and adolescents, the dosage can be increased after a few weeks if there isn't any improvement observed in symptoms, but the maximum daily dose should not exceed 20 mg under any circumstances. Always consult your healthcare provider for personalized medical advice about side effects or specific drug interactions.

At what dose is Lyrica typically prescribed?
Lyrica treatment generally begins with a dosage of 75 mg/day. If needed, the dose can be increased to 150 mg/day after one week, divided into two doses spaced about 12 hours apart. The maximum recommended dose is 600 mg/day divided into two or three doses (300-200-100mg) and spaced evenly throughout the day. This may be considered if there is no response to treatment at lower dosages after an appropriate length of time. It's important to remember that any adjustments should always be under the supervision of a healthcare provider.

- Rapid heart rate or chest fluttering; shortness of breath; sudden dizziness (like you might pass out)
- Severe muscle reaction—very stiff (rigid) muscles; high fever; sweating; confusion
- Signs of a severe skin reaction like red/purple skin rash with blistering/peeling
In either situation if one experiences any above mentioned symptoms it's crucial to seek medical help immediately.
What are the most common side effects for Lyrica?
Lyrica, an anticonvulsant and neuropathic pain medication, comes with its own set of potential side effects:
- Dry mouth
- Blurred vision
- Constipation
- Nausea or vomiting
- Dizziness and headache
- Fatigue or drowsiness
- Unintended weight gain
- Hand tremors
- Anxiety or confusion
- Trouble sleeping (insomnia)
- Swelling in your hands, legs, and feet.
Some people may also experience muscle weakness or joint pain. It's important to note that these are possible side effects - not everyone taking Lyrica will experience them. If you do notice any of these symptoms while on the medication, it's crucial to discuss them with your healthcare provider.
Are there any potential serious side effects for Lyrica?
While Lyrica is widely used and generally well-tolerated, it's not without potential side effects. Serious reactions to this medication can include:
- Severe allergic reactions: Symptoms may include hives, itching, blisters, red or purple skin rashes with blistering or peeling.
- Mental health changes: These can include increased thoughts of suicide or self-harm.
- Neurological issues: Some patients experience seizures while on this medication.
- Vision problems: Blurred vision or other visual disturbances have been reported.
- Heart irregularities: Rapid heartbeat has been noted among some users of Lyrica.
- Mood Changes: Unusual mood swings including feeling unusually elated, irritable, restlessness and displaying reckless behavior might be observed.
If you experience any of these symptoms while taking Lyrica, it's important to contact your doctor immediately for further guidance.
Contraindications for Lexapro and Lyrica?
Both Lexapro and Lyrica, like many other antidepressant and anticonvulsant medications respectively, may worsen symptoms of depression or anxiety in some people. If you notice your mental health declining, or a rise in suicidal thoughts or behavior, please seek immediate medical help.
Neither Lexapro nor Lyrica should be taken if you are taking—or have recently stopped taking—MAO inhibitors (MAOIs). It's crucial to inform your doctor about any medications you're currently on; MAOIs need approximately 2 weeks after discontinuation before starting a drug like Lexapro due to the risk of serotonin syndrome. Similarly, abrupt withdrawal from drugs like Lyrica can cause complications such as seizures; hence it is important that the dose is tapered off under medical supervision.
How much do Lexapro and Lyrica cost?
For the brand name versions of these drugs:
- The price of 30 capsules of Lexapro (10 mg) averages around $356, which works out to approximately $11.87/day.
- The cost for 60 capsules of Lyrica (75 mg) is about $470, working out to roughly $7.83/day.
Hence, if you are in a higher dosage range for Lexapro (i.e., 20 mg/day), then brand-name Lyrica can be less expensive on a per-day treatment basis. However, remember that cost should not be your main consideration when determining which drug is appropriate for you.
As for the generic versions of these medications:
-
Escitalopram (the generic version of Lexapro) comes in packs ranging from 5 to 500 tablets with an approximate daily cost varying between as low as $0.14 up to about $3 based on the quantity purchased and dosage taken.
-
Pregabalin (the generic version of Lyrica) is available in various quantities starting at 21 capsules up to larger sizes with costs generally falling between about $1 and nearly over $4 per day depending on dosage and package size bought upfront.
Keep in mind that prices can differ based on location, insurance coverage, pharmacy used, and other factors.
Popularity of Lexapro and Lyrica
Escitalopram, available in generic form and under the brand name Lexapro, was estimated to have been prescribed about 27 million times in the US in 2020. Escitalopram is an SSRI (Selective Serotonin Reuptake Inhibitor) that accounted for just over 18% of all SSRI prescriptions across the country. This antidepressant has seen a steady rise in usage since its introduction on the market.
Pregabalin, known by its brand name Lyrica, was prescribed roughly 10 million times during the same year. It is primarily used to treat epilepsy, neuropathic pain and fibromyalgia but also anxiety disorders. While Pregabalin isn't classified as an antidepressant like escitalopram - it belongs to a class of medicine called antiepileptics or anticonvulsants - it still plays a significant role in mental health treatments and thus competes with escitalopram when considering different treatment plans for conditions such as generalized anxiety disorder.
Conclusion
Both Lexapro (escitalopram) and Lyrica (pregabalin) have established records of use in the management of various mental health and neurological conditions. They are backed by numerous clinical studies indicating their effectiveness over placebo treatments. Occasionally, these drugs may be used together, but this should be subject to careful consideration by a physician due to potential drug interactions. Lexapro primarily acts as a selective serotonin reuptake inhibitor (SSRI), making it commonly prescribed for depression or generalized anxiety disorder. On the other hand, Lyrica works by binding to calcium channels in nerve cells, reducing neurotransmitter release and is typically administered for neuropathic pain disorders like fibromyalgia or postherpetic neuralgia.
Both medications are available in generic forms which offers significant cost savings especially for patients who must pay out-of-pocket. Both Lexapro and Lyrica require an adjustment period; hence effects might not be evident immediately.
Side effect profiles differ between these two medications with Lexapro possibly causing sexual dysfunction or weight gain while Lyrica could lead to dizziness or sedation due to its central nervous system activity. With both drugs, patients must monitor any changes in mood or physical state closely when initiating treatment and seek immediate medical attention if they notice worsening symptoms or thoughts about self-harm.
