Effexor Xr vs Wellbutrin
Introduction
For patients with major depressive disorder (MDD) or other types of depression, certain drugs that alter the concentrations of neurotransmitters in the brain can help stabilize mood and manage symptoms. Effexor XR and Wellbutrin are two such medications commonly prescribed for depression. They each impact different neurotransmitters in the brain but both have mood-stabilizing effects in patients with depression. Effexor XR is a serotonin-norepinephrine reuptake inhibitor (SNRI), affecting levels of serotonin and norepinephrine to alleviate depressive symptoms. On the other hand, Wellbutrin falls under the category of norepinephrine-dopamine reuptake inhibitors (NDRI) as well as being a nicotinic acetylcholine receptor antagonist, primarily influencing levels of dopamine and norepinephrine.
What is Effexor Xr?
Venlafaxine (the generic name for Effexor XR) is a noteworthy drug that belongs to the SNRI class of antidepressants, an evolution from the first generation of SSRI antidepressant drugs. Venlafaxine received FDA approval in 1993. Unlike Prozac, Effexor XR increases levels not only of serotonin but also norepinephrine and to a lesser degree dopamine by inhibiting their reuptake into cells in the brain. It’s prescribed for treating various forms of depression as well as anxiety disorders and panic disorder. The impact on three neurotransmitters instead of one distinguishes it from SSRIs like Prozac and could potentially result in more side effects due to its broader spectrum action. However, this triple-action effect may make it more effective than SSRIs for certain individuals.
What conditions is Effexor Xr approved to treat?
Effexor XR is approved for the treatment of several mental health conditions, including:
- Major depressive disorder (MDD), also known as unipolar depression
- Generalized anxiety disorder (GAD)
- Social anxiety disorder
- Panic disorder
Whereas Wellbutrin is typically used in treating:
- Major depressive disorders
- Prevention of seasonal affective disorders
How does Effexor Xr help with these illnesses?
Effexor XR helps manage depression by increasing the levels of serotonin and norepinephrine in the brain's synapses. It accomplishes this by inhibiting their reuptake into neurons, allowing these neurotransmitters to remain available for longer periods. Both serotonin and norepinephrine are key messengers in the brain that impact mood, cognition, memory, sleep patterns, hunger among other things. It is suggested that people with depression often have lower levels of these neurotransmitters. Therefore, Effexor XR enhances both serotonin and norepinephrine levels which can mitigate depressive symptoms and help patients control their condition as well as stabilize their mood.
Wellbutrin also works on neurotransmitter regulation but it primarily increases dopamine availability in addition to norepinephrine rather than focusing on serotonin like many other antidepressants do including Prozac or Effexor XR.
What is Wellbutrin?
Wellbutrin, also known as bupropion, is a norepinephrine-dopamine reuptake inhibitor (NDRI), which enhances the levels of norepinephrine and dopamine in the brain by reducing their absorption. It also mildly inhibits the action of acetylcholine on nicotinic acetylcholine receptors. This drug was first sanctioned by the FDA in 1986. Since Wellbutrin isn't an SSRI antidepressant like Effexor XR (venlafaxine hydrochloride), it doesn't interfere with serotonin reabsorption. Consequently, its side effect profile differs from that of SSRIs; for example, it does not induce sedation nor is it likely to cause weight gain or sexual dysfunction, common side effects linked with many SSRIs such as Effexor XR. The impact on dopamine and norepinephrine can be advantageous in treating depression, particularly among patients who don’t respond well to “typical” SSRI antidepressants such as Effexor XR.
What conditions is Wellbutrin approved to treat?
Wellbutrin is a medication that has been approved by the FDA to treat:
- Major depressive disorder (MDD)
- Seasonal affective disorder (SAD), also known as "winter depression".
Unlike Effexor XR, which primarily works on serotonin and norepinephrine, Wellbutrin has a unique mechanism of action focusing on dopamine and norepinephrine. This difference can make Wellbutrin a better choice for certain patients, depending upon their specific symptoms and medical history.
How does Wellbutrin help with these illnesses?
Dopamine, a neurotransmitter which also acts as a hormone, plays critical roles in modulating mood, reward-driven behavior and attention. It is heavily involved in the pleasure-reward system of the brain. A deficiency or imbalance of dopamine has been associated with depression. Wellbutrin works by increasing levels of both norepinephrine and dopamine available in the brain, thereby potentially alleviating some symptoms of depression. Its unique action on these neurotransmitters sets it apart from other types of antidepressants making it an important alternative for patients who don't respond well to medications like Effexor XR that primarily affect serotonin levels. Unlike many "typical" SSRIs (such as Prozac) or SNRIs (like Effexor XR), Wellbutrin doesn't significantly affect serotonin levels but focuses more on norepinephrine and dopamine pathways instead.
How effective are both Effexor Xr and Wellbutrin?
Both venlafaxine extended-release (Effexor XR) and bupropion (Wellbutrin) have a strong track record in treating patients with depression, both receiving FDA approval in the 1990s. These two antidepressants work on different neurotransmitters which means they may be used under distinct circumstances based on individual patient needs. A double-blind clinical trial conducted between these two drugs demonstrated comparable efficacy in managing symptoms of depression along with similar safety profiles.
A review published in 2006 showed that Effexor XR is effective from the first week of treatment onset, bearing an advantageous side effect profile over numerous other antidepressants and being well-tolerated among various population groups including elderly individuals. The same study highlighted its global use as one of the most commonly prescribed SNRI (Serotonin-Norepinephrine Reuptake Inhibitor). Moreover, it has been extensively studied for its effectiveness against major depressive disorders since its introduction to the market. Optimal therapeutic effects are often achieved at doses around 150mg/day.
On the other hand, a meta-analysis from 2018 indicated that Wellbutrin appears to be more potent than placebo in treating depression and matches up favorably against other typical antidepressants. However, it is usually regarded as a second or third-line treatment option after SSRIs or SNRIs have proven ineffective or unsuitable due to side-effects. Much research concerning Wellbutrin involves cases where it's co-prescribed with another SSRI; thus data confirming its standalone efficacy isn't as comprehensive compared to Effexor XR's evidence base. Despite this fact, given bupropion’s unique pharmacological properties – specifically avoiding common SSRI-associated sexual dysfunction - it could provide optimal results for those who had little success with SSRIs/SNRIs or need to bypass certain adverse effects associated with them.
At what dose is Effexor Xr typically prescribed?
Oral dosages of Effexor XR range from 37.5–225 mg/day, but studies have indicated that a daily dose of 75 mg is often sufficient for treating major depressive disorder in most adults. Adolescents and children above the age of 13 may be started on a lower dose which can be increased gradually based on response and tolerability. In either population, dosage can be increased after a few weeks if there is no improvement in symptoms. However, the maximum dosage should not exceed 225 mg/day under any circumstances.

At what dose is Wellbutrin typically prescribed?
The treatment with Wellbutrin typically begins at a dosage of 150 mg/day, taken once in the morning for the initial few days. The dose can then be increased to 300 mg/day, divided into two doses of 150 mg each, ideally spaced approximately 8 hours apart. If required and under physician's guidance, the maximum dose can reach up to 450 mg/day divided into three doses of 150 mg each and should be spaced about six hours apart. This is generally explored if there hasn't been an adequate response to treatment at a daily intake of 300mg after several weeks.
What are the most common side effects for Effexor Xr?
Common side effects associated with Effexor XR include:
- Nervousness and anxiety
- Insomnia, or trouble sleeping
- Somnolence, or sleepiness/drowsiness
- Fatigue or general weakness
- Tremors or unintentional trembling/shaking movements
- Loss of appetite (anorexia)
- Nausea and vomiting
- Dyspepsia, which includes symptoms like burning discomfort or pain in the digestive tract
- Diarrhea
- Dry mouth
Decreased sex drive (libido), abnormal ejaculation and impotence.
In some cases people might experience skin rash, excessive sweating, unusual dreams, flu-like symptoms such as fever and muscle aches (flu syndrome). Infections affecting the throat (pharyngitis) and sinus cavities causing inflammation (sinusitis) have also been reported. Some patients may even report frequent yawning.
Are there any potential serious side effects for Effexor Xr?
Effexor XR, like Wellbutrin, is generally well-tolerated but it can occasionally cause serious side effects. These include:
- Increased suicidal thoughts or self-harming tendencies: This risk is particularly high in users under the age of 25 and tends to occur during the start of treatment.
- Signs of a severe allergic reaction: hives; difficulty breathing; swelling in your face, lips, tongue, or throat
- Eye problems: These could range from blurred vision to pain and swelling around the eyes. It might also lead to seeing halos around lights.
- Heart issues: Rapid heartbeat, chest fluttering sensation coupled with shortness of breath and sudden dizziness may occur.
- Low sodium levels (hyponatremia): Symptoms are headache, confusion, slurred speech, severe weakness, vomiting loss of coordination and an unsteady feeling.
- A serious nervous system reaction - symptoms can include rigid muscles accompanied by high fever sweating confusion rapid heartbeats tremors and fainting spells. -Symptoms indicative of serotonin syndrome such as agitation hallucinations increased temperature sweating shivering accelerated heart rate muscle stiffness twitching lack of coordination nausea vomiting or diarrhea.
If you experience any such symptoms while on Effexor XR therapy make sure you seek immediate medical attention.
What are the most common side effects for Wellbutrin?
Wellbutrin, compared to Effexor XR, can have side effects that include:
- Dry mouth and sore throat
- Blurred vision or eye strain
- Weight loss due to decreased appetite
- Sweating more than usual
- Increased heart rate, feeling jittery or anxious
- Sleep disturbances including insomnia
- Possible confusion or agitation in some cases
- Aches and pains in the joints and muscles of your body.
It's noteworthy that Wellbutrin tends not to cause as many issues with sexual dysfunction compared to other antidepressants like Effexor XR. However, it may lead to an increased risk of seizures so should be used cautiously in those susceptible.
Are there any potential serious side effects for Wellbutrin?
Wellbutrin, while generally well-tolerated, can cause certain side effects in rare instances. These may include:
- Severe allergic reactions such as hives, itching or skin rash; swelling of the face, lips or tongue; difficulty breathing and chest tightness
- Mood changes like agitation and hostility, depressed mood or thoughts of suicide
- The onset of seizures (convulsions)
- Cognitive confusion or unusual changes in behavior
- Visual disturbances: blurred vision, eye pain/swelling/redness/burning sensation; experiencing a halo around lights
- Cardiovascular issues: irregular heart rate that's too fast or fluttering
- Manifestations suggestive of a manic phase including hyperactive thought process and speech pattern, an uncharacteristic increase in energy levels which might lead to reckless behaviors along with significant sleep disruptions.
If any such symptoms are noted after starting Wellbutrin treatment, it is advised to contact your healthcare provider promptly.
Contraindications for Effexor Xr and Wellbutrin?
Both Effexor XR and Wellbutrin, similar to other antidepressant medications, may exacerbate symptoms of depression in some individuals. If you observe your depressive symptoms intensifying or any increase in suicidal thinking or behavior, seek immediate medical assistance.
Neither Effexor XR nor Wellbutrin should be used if you are currently taking, or have recently taken monoamine oxidase (MAO) inhibitors. It's important to inform your healthcare provider about all the medications you use; MAOIs will require approximately 5 weeks to eliminate from the system completely before initiating treatment with either Effexor XR or Wellbutrin in order to prevent harmful interactions.
How much do Effexor Xr and Wellbutrin cost?
For the brand name versions of these drugs:
- The price of 60 tablets of Wellbutrin SR (100 mg) averages around $500, which works out to approximately $16–32/day, depending on your dose.
- The cost for Effexor XR ranges significantly based on dosage and quantity. A 30-day supply at a common dose of 75mg can range from about $200-$300, working out to roughly $6.70–$10/day.
Thus, if you are in the higher dosage range for Wellbutrin (i.e., 300 mg/day or higher), then brand-name Effexor XR is less expensive on a per-day treatment basis. However, the cost should not be a primary consideration in determining which medication is right for you.
As for generic versions of both medications:
-
Bupropion (generic form of Wellbutrin) prices vary but it's generally quite affordable with costs ranging between approximately $0.25 to $0.80 per day for dosages of 100 mg/day or between roughly $.50 -1.50 per day if you are taking more typical dosages from up to 300mg daily.
-
Venlafaxine ER is available as a generic version of Effexor XR and comes in packs starting from as low as $.15 up to about $.60 per day depending upon various factors including dosage required and where it's purchased.
Remember that while considering costs can be important when choosing medications, effective symptom management remains paramount—discuss options thoroughly with your healthcare provider before making any decisions.
Popularity of Effexor Xr and Wellbutrin
Venlafaxine, in generic form as well as brand names such as Effexor XR, was estimated to have been prescribed to about 8.8 million people in the US in 2020. Venlafaxine accounted for just over 15% of SNRI (Serotonin-Norepinephrine Reuptake Inhibitors) antidepressant prescriptions in the US. However, it appears to be a popular choice among atypical antidepressants due its dual action on both serotonin and norepinephrine levels within the brain. The prescription trend for venlafaxine has remained relatively stable since its initial approval by FDA back in 1993.
Bupropion or Wellbutrin, on the other hand, was prescribed to approximately 5.8 million people during the same year. Accounting for around 12% of all antidepressant prescriptions written, bupropion is widely used primarily because it does not fit into traditional classes like SSRIs or SNRIs but works effectively against depression symptoms with less sexual side effects caused frequently by other types of antidepressants.. Bupropion's prevalence has been increasing consistently since its introduction.
Conclusion
Both Effexor XR (venlafaxine) and Wellbutrin (bupropion) are commonly prescribed medications for the treatment of depression, with a wealth of clinical research backing their effectiveness over placebo treatments. In some instances, these drugs might be used together, but such decisions require careful evaluation by medical professionals due to possible contraindications. The two have different mechanisms of action: Effexor XR primarily impacts serotonin and norepinephrine neurotransmitters – making it an SNRI – while Wellbutrin mainly affects norepinephrine and dopamine.
Effexor XR is often considered as a first-line treatment option in patients suffering from major depressive disorders or generalized anxiety disorder, while Wellbutrin tends to be recommended as an adjunctive therapy alongside other antidepressants like SSRIs or SNRIs, or for those who did not respond well to initial treatments or need to avoid common sexual side effects associated with many antidepressants.
Both medications are available in generic forms which can offer substantial cost savings particularly for individuals paying out-of-pocket. It's important to note that both Effexor XR and Wellbutrin may necessitate an adjustment period; immediate relief should not be expected.
The side effect profiles for both medicines show general tolerability among most patients. However, compared with Effexor XR which could lead to sexual dysfunction and weight gain among other things, Wellbutrin is less likely to cause these particular undesirable effects. For all users of either drug, close monitoring especially at the beginning of treatment is essential; any worsening depression symptoms or emergence of suicidal thoughts demands immediate medical intervention.
