Pexeva vs Paxil
Introduction
For patients with major depressive disorder (MDD) or other types of mood disorders, certain medications that manipulate levels of neurotransmitters - brain chemicals linked to mood - can be instrumental in stabilizing depressive episodes and managing symptoms. Pexeva and Paxil are two such drugs often prescribed for these conditions. Both impact the same neurotransmitter in the brain, serotonin, but there are differences to consider when choosing between these two selective serotonin-reuptake inhibitors (SSRIs). Pexeva is a branded formulation of paroxetine mesylate while Paxil is a well-known brand name for paroxetine hydrochloride. Although they contain slightly different salts, both have similar effects on elevating serotonin levels which helps enhance mood stability in patients with depression.
What is Pexeva?
Paroxetine (the generic name for Pexeva and Paxil) is a type of SSRI (Selective Serotonin Reuptake Inhibitor) developed following the major advances provided by the first class of antidepressant drugs, known as tricyclic antidepressants (TCAs). Paroxetine was first approved by the FDA in 1992. Both Pexeva and Paxil increase levels of free serotonin by preventing it from being reabsorbed, effectively keeping it within the brain’s synapses longer than usual. This mechanism aids in regulating mood hence, these drugs are prescribed for treating various forms of depression along with other mental health disorders such as anxiety and panic attacks. While both medications have similar mechanisms of action, they differ slightly in their formulations: Pexeva contains paroxetine mesylate while Paxil contains paroxetine hydrochloride. Despite these differences, both versions aim to influence serotonin significantly with only minor impacts on dopamine and norepinephrine — resulting in fewer side effects compared to other antidepressants that strongly affect these two neurotransmitters.
What conditions is Pexeva approved to treat?
Pexeva is approved for the treatment of several mental health conditions:
- Major depressive disorder (MDD), also known as unipolar depression
- Generalized anxiety disorder (GAD)
- Panic disorder, with or without agoraphobia
- Obsessive-compulsive disorder (OCD)
How does Pexeva help with these illnesses?
Pexeva helps to manage depression by increasing the quantity of serotonin available in the brain's synapses. Similar to Prozac, Pexeva prevents serotonin from being reabsorbed too quickly by neurons, thereby maintaining higher levels for extended periods. As a neurotransmitter, serotonin serves as a messenger throughout the body and plays key roles in mood regulation, cognition, memory formation, sleep patterns and various other functions. It is believed that individuals with depression often have lower than normal levels of serotonin; thus by boosting its amount via medication like Pexeva can help alleviate depressive symptoms and stabilize mood swings.
It should be noted that Pexeva is essentially identical to Paxil (both contain paroxetine), but they are produced by different companies and may come with slightly varying side effects based on non-active ingredients used in their production process. Always consult your healthcare provider before switching between similar medications.
What is Paxil?
Paxil is a brand name for paroxetine, which is a selective serotonin reuptake inhibitor (SSRI), meaning it increases the levels of serotonin in the brain by reducing its reabsorption. It also acts as an anticholinergic agent, meaning it blocks the action of another neurotransmitter, acetylcholine, at muscarinic acetylcholine receptors. Paroxetine was first approved by the FDA in 1992. Unlike bupropion (Wellbutrin), Paxil does inhibit the reuptake of serotonin and thus primarily affects this particular neurotransmitter. Its primary effect on serotonin means that its side-effect profile is different from non-SSRI antidepressants - it may cause sedation and has been associated with weight gain and sexual dysfunction (common side effects of SSRIs such as Prozac). Nonetheless, Paxil's effect on serotonin can be beneficial in treating depression especially among patients who have not responded well to other types of antidepressant drugs like Pexeva.
What conditions is Paxil approved to treat?
Paxil is an FDA-approved medication for the treatment of several conditions, including:
- Major depressive disorder (MDD)
- Generalized anxiety disorder (GAD)
- Panic disorder
- Obsessive-compulsive disorder (OCD)
- Social anxiety disorder, also known as social phobia.
How does Paxil help with these illnesses?
Serotonin is a neurotransmitter that plays fundamental roles in regulating mood, social behavior, appetite and digestion, sleep, memory and sexual desire. It has been suggested that low levels of serotonin are associated with depression. Paxil works by inhibiting the reuptake of serotonin available in the brain's synaptic spaces, thereby amplifying its effects and alleviating some symptoms of depression. The action on other neurotransmitters may also contribute to Paxil’s antidepressant properties. Unlike Pexeva which is formulated as paroxetine mesylate (a salt form), Paxil uses paroxetine hydrochloride for improved absorption rates and bioavailability. This makes it an effective choice when a patient doesn't respond well to other SSRI antidepressants or if combined treatment strategies are required.
How effective are both Pexeva and Paxil?
Both paroxetine mesylate (Pexeva) and paroxetine hydrochloride (Paxil) are selective serotonin reuptake inhibitors (SSRIs) with proven effectiveness in treating patients with depression, anxiety disorders, and other psychiatric conditions. They share the same active ingredient, paroxetine, but differ slightly in their salt forms - mesylate for Pexeva and hydrochloride for Paxil. These two drugs were approved by the FDA several years apart: Paxil in 1992 while Pexeva was later introduced to the market in 2003.
The efficacy of both medications is well-documented through numerous clinical trials demonstrating their ability to alleviate symptoms of depression and anxiety disorders effectively. In these studies, there were no significant differences between patients receiving Pexeva or those receiving Paxil regarding metrics used to measure treatment success.
A review published in 2006 revealed that starting from the first week of treatment with either drug, noticeable reductions can be observed in depressive symptoms. Both drugs have a favorable side effect profile compared to many older antidepressants; however, like most SSRIs they may lead to sexual side effects such as reduced libido or orgasmic dysfunction.
As per a meta-analysis conducted in 2018 examining SSRI use for major depressive disorder management, paroxetine-containing agents like Paxil & Pexeva offer comparable efficacy when pitted against other common antidepressants. While considered first-line treatments for depressive disorders due to their safety profiles and high tolerability across patient populations including pregnant women and elderly individuals; cost-effectiveness often dictates choice among these options.
It's noteworthy that despite being essentially similar therapeutically; one distinct advantage offered by Pexeva over Paxil lies within its patent status allowing it some marketing leeway not afforded by generic counterparts which translates into better availability at times due to more aggressive distribution strategies employed by manufacturers.
At what dose is Pexeva typically prescribed?
Oral dosages of Pexeva typically range from 20–60 mg/day, with studies suggesting that a dose of 20 mg/day is efficient in treating many individuals with major depressive disorder. Adolescents may be started on a lower dosage - often 10 mg/day. If there's no response after a few weeks, the dosage can be increased under medical supervision. However, it's crucial to note that in any circumstance, the maximum daily dosage should not exceed 60 mg/day.

At what dose is Paxil typically prescribed?
Paxil therapy typically starts at a dose of 20 mg per day. Depending on the response and tolerance, the dosage can be gradually increased in increments of 10 mg per day, spaced one week apart. The maximum recommended dose for most conditions is 60 mg/day divided into single or two doses. For certain specific disorders like obsessive-compulsive disorder (OCD), this may be raised to an upper limit of 75 mg/day if there has been no adequate response after several weeks at lower dosages. As always, any changes in dosage should only be made under your doctor's guidance.
What are the most common side effects for Pexeva?
Common side effects of both Pexeva and Paxil include:
- Anxiety
- Nervousness
- Trouble sleeping (insomnia)
- Drowsiness
- Tiredness or weakness (asthenia)
- Shaking or trembling (tremor)
- Loss of appetite
- Nausea
- Upset stomach (dyspepsia)

These medications are quite similar as they're both selective serotonin reuptake inhibitors. If you experience any serious side effects such as hallucinations, easy bruising/bleeding, fast heartbeat, severe nausea/vomiting/diarrhea, twitching muscles, unexplained fever and unusual agitation/restlessness among others please seek medical help immediately.
Are there any potential serious side effects for Pexeva?
Pexeva and Paxil are both brands of the drug paroxetine. Regardless of brand, potential side effects may include:
- Thoughts about suicide or self-harm
- Signs of allergic reaction: hives, difficulty breathing, swelling in your face or throat
- Severe skin reaction symptoms: fever, sore throat, burning eyes, skin pain or a red/purple skin rash with blistering and peeling.
- Ocular disturbances such as blurred vision, tunnel vision, eye pain/swelling or seeing halos around lights
- Cardiovascular symptoms including fast/pounding heartbeat; chest fluttering; shortness of breath; sudden dizziness (feeling like you might pass out)
- Symptoms indicating low sodium levels in the body - headache; confusion; slurred speech; severe weakness; vomiting; loss of coordination feeling unsteady
- Severe nervous system reactions - very stiff (rigid) muscles high fever sweating confusion fast/uneven heartbeats tremors feeling like you might pass out.
If any signs suggestive of serotonin syndrome appear - agitation hallucinations fever sweating shivering fast heart rate muscle stiffness twitching loss of coordination nausea vomiting diarrhea – immediate medical attention is necessary.
What are the most common side effects for Paxil?
Paxil, a common medication used to treat anxiety and depression disorders, has several potential side effects that users should be aware of:
- Dry mouth or throat
- Sweating
- Nausea, occasional vomiting, upset stomach or mild constipation
- Sleep disturbances such as insomnia
- Mild tremors or feeling nervous/anxious
- Slight changes in heart rate
- Potential for confusion or agitation
- Skin rash (though this is less common)
- Possible fluctuations in weight
Are there any potential serious side effects for Paxil?
While Paxil is generally well-tolerated, it does have the potential for serious side effects in some individuals. These may include:
- Signs of an allergic reaction such as difficulty breathing; swelling of your face, lips, tongue, or throat
- Unusual changes in behavior or mood swings including agitation, hostility, restlessness
- Symptoms resembling serotonin syndrome: fast heartbeat, hallucinations (seeing or hearing things that are not real), loss of coordination
- Intense nervousness or anxiety
- Easy bruising and unusual bleeding (nosebleeds)
- Severe nausea and vomiting
- Sudden weight loss
In rare cases Paxil can cause a severe skin reaction that needs to be treated in a hospital. If you experience any severe symptoms while taking Paxil seek immediate medical attention.
Contraindications for Pexeva and Paxil?
Just like Paxil and Pexeva, as with most other antidepressants, there's a risk that these medications may exacerbate symptoms of depression in specific individuals. If you observe your mental health deteriorating or experience an upsurge in suicidal thoughts or tendencies while taking either Paxil or Pexeva, it is crucial to seek emergency medical care.
Neither Pexeva nor Paxil should be taken if you're currently on, or have recently stopped using monoamine oxidase inhibitors (MAOIs). It's vital to inform your healthcare provider about all the medications you are taking; after stopping MAOI treatment, there needs to be a clearance period of approximately five weeks before starting on Paxil or Pexeva to avoid hazardous drug interactions.
How much do Pexeva and Paxil cost?
For the brand name versions of these drugs:
- The price for 30 tablets of Paxil (20 mg) averages around $130, which works out to approximately $4.33/day.
- The price for 30 capsules of Pexeva (20 mg), a similar drug, averages about $230 or roughly $7.67/day.
Thus, if you are on a standard dosage level for either drug (i.e., 20 mg/day), then brand-name Paxil 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 the generic versions - paroxetine and paroxetine mesylate respectively - costs are significantly lower:
- Generic Paxil/paroxetine (20mg tablets) is available in packs from 10 up to hundreds with approximate costs starting at around $0.50 per day depending on quantity purchased and your daily dose.
- Paroxetine Mesylate, the generic version of Pexeva comes with similar pricing strata but may vary slightly based on manufacturer and pharmacy.
Please remember that each person's reaction to medication can differ greatly; therefore it is important to consult with your healthcare provider before making any changes regarding medication.
Popularity of Pexeva and Paxil
Paroxetine, available in generic form as well as under brand names like Pexeva and Paxil, is a commonly prescribed selective serotonin reuptake inhibitor (SSRI). It was estimated to have been dispensed to about 3.4 million people in the US in 2020. Paroxetine accounted for just over 7% of SSRI prescriptions and around 5% of all antidepressant prescriptions within that year.
The use of paroxetine has seen a general decline since its peak usage period due to the emergence of newer SSRIs with fewer side effects. A branded version such as Pexeva is typically more expensive than Paxil or generic paroxetine, but it may be preferred by some patients who respond better to specific brands. Both versions are used primarily for treating conditions such as depression, obsessive-compulsive disorder (OCD), anxiety disorders, post-traumatic stress disorder (PTSD), and premenstrual dysphoric disorder (PMDD). Their difference lies mainly in their formulation and pricing rather than effectiveness or safety profiles.
Conclusion
Both Pexeva (paroxetine mesylate) and Paxil (paroxetine hydrochloride) have long-standing records of usage in patients with depression, anxiety disorders, and other mental health conditions. Their effectiveness has been demonstrated by various clinical studies and meta-analyses showing that they are more potent than placebo treatments. Both drugs belong to the class of selective serotonin reuptake inhibitors (SSRIs), acting primarily on serotonin levels in the brain.
Paxil is generally considered as a first-line treatment option for several psychiatric disorders, while Pexeva tends to be prescribed when other SSRIs haven't provided satisfactory results or when certain side effects need to be avoided. Despite their similar mechanisms of action, they can cause different reactions due to their unique chemical structures.
Both medications are available in generic form which represents significant cost savings especially for those who must pay out of pocket. The drugs may require an adjustment period; thus, effects may not be noticeable immediately after starting treatment.
The side effect profile is similar between these two medications; however, Pexeva might offer slightly fewer sexual dysfunction side-effects compared to Paxil. Patients taking either drug should closely monitor their moods and seek medical help immediately if symptoms worsen or if suicidal thoughts arise.
