Wellbutrin vs Zoloft
Introduction
For individuals suffering from major depressive disorder (MDD) or other forms of depression, certain medications can be beneficial in managing symptoms and stabilizing mood. These drugs work by modifying the concentration of neurotransmitters within the brain which are associated with mood regulation. Wellbutrin and Zoloft are two such commonly prescribed antidepressants. They both influence different neurotransmitters but share a common outcome – mood stabilization for patients with depression. Wellbutrin is categorized as a norepinephrine-dopamine reuptake inhibitor (NDRI), primarily affecting levels of norepinephrine and dopamine in the brain. On the contrary, Zoloft belongs to selective serotonin reuptake inhibitors (SSRIs), meaning it has an effect on serotonin levels mainly.

What is Wellbutrin?
Bupropion (the generic name for Wellbutrin) is a medication of the norepinephrine-dopamine reuptake inhibitor (NDRI) class, which represents a significant breakthrough from the first class of antidepressant drugs known as tricyclic antidepressants. Bupropion was first approved by the FDA in 1985. It works by increasing levels of dopamine and norepinephrine in the brain by inhibiting their reuptake into neurons, effectively enhancing their availability and action on neural circuits involved in mood regulation. It is prescribed for treating depression and seasonal affective disorder, among other conditions.
On another side, Sertraline (Zoloft), an SSRI drug that gained FDA approval in 1991, primarily works to elevate serotonin levels by preventing its reabsorption into neurons—similarly prolonging its effects within the brain. Zoloft has a selective influence on serotonin with little effect on dopamine or norepinephrine neurotransmission which may result in fewer side effects compared to other medications with broader mechanisms of action affecting multiple neurotransmitters.
What conditions is Wellbutrin approved to treat?
Wellbutrin is sanctioned for the treatment of different types of depression and conditions:
- Major depressive disorder (MDD), also known as unipolar depression
- Seasonal affective disorder, a type of depression that usually occurs in the fall or winter seasons
- Smoking cessation assistance, as it can reduce cravings and withdrawal effects.
How does Wellbutrin help with these illnesses?
Wellbutrin assists in managing depression by increasing the levels of norepinephrine and dopamine available in your brain's synapses. It achieves this by inhibiting their reuptake, meaning these neurotransmitters remain available for longer periods. Norepinephrine and dopamine are both neurotransmitters that play crucial roles in mood regulation, attention, motivation, pleasure responses and several other cognitive processes. People with depression often show lower-than-average amounts of these substances within their brains. So by elevating the availability of norepinephrine and dopamine, Wellbutrin can contain depressive symptoms while assisting individuals to manage their condition effectively.
Zoloft operates a bit differently from Wellbutrin; it is classified as a selective serotonin reuptake inhibitor (SSRI). Its primary function is to increase the level of serotonin in the brain's synapses by blocking its reabsorption into neurons. Serotonin impacts various bodily functions including mood balance, arousal states, sleep cycle, appetite control among others. Just like norepinephrine and dopamine deficiencies lead to depression symptoms so does low levels of serotonin have similar effects on an individual's mental state.
What is Zoloft?
Zoloft is a brand name for sertraline, which is a selective serotonin reuptake inhibitor (SSRI), meaning it increases the levels of serotonin in the brain by reducing its reabsorption. Unlike bupropion, sertraline does not significantly affect norepinephrine and dopamine reuptake or act as an antagonist at nicotinic acetylcholine receptors. This means that its side-effect profile is different from that of Wellbutrin; while Zoloft might cause side effects like weight gain or sexual dysfunction — common to many SSRIs — it doesn't typically result in the agitation or insomnia associated with Wellbutrin's impact on dopaminergic and noradrenergic systems. Sertraline was first approved by the FDA in 1991 and can be beneficial for treating depression, especially obsessive-compulsive disorder, panic disorder and social anxiety disorder. Its action on serotonin makes it a "typical" SSRI antidepressant, often serving as a first-line treatment option.
What conditions is Zoloft approved to treat?
Zoloft, also known as sertraline, is a selective serotonin reuptake inhibitor (SSRI) that's approved for a broad range of psychiatric conditions. These include:
- Major depressive disorder (MDD)
- Obsessive-compulsive disorder (OCD)
- Panic disorder
- Post-traumatic stress disorder (PTSD)
- Social anxiety Disorder
- Premenstrual dysphoric disorder (PMDD)
While both Wellbutrin and Zoloft can be used to treat depression, the range of disorders that Zoloft is approved for is much broader.
How does Zoloft help with these illnesses?
Serotonin is a neurotransmitter that plays a vital role in maintaining mood balance, sleep regulation, and overall sense of well-being. Low levels of serotonin have been implicated in depression and anxiety disorders. Zoloft works by increasing the levels of serotonin available in the brain, thereby alleviating some symptoms associated with depression or anxiety. Its action on this specific neurotransmitter classifies it as an SSRI (Selective Serotonin Reuptake Inhibitor). Unlike Wellbutrin which primarily increases norepinephrine and dopamine, Zoloft specifically targets serotonin pathways. Due to its efficacy and tolerability profile, Zoloft is often prescribed as first-line therapy when treating conditions such as major depressive disorder or generalized anxiety disorder where low levels of serotonin are suspected.
How effective are both Wellbutrin and Zoloft?
Bupropion (Wellbutrin) and sertraline (Zoloft) are both effective treatments for depression and were approved by the FDA within a few years of each other. They act on different neurotransmitters - bupropion affects dopamine and norepinephrine, while sertraline primarily impacts serotonin. Their effectiveness in alleviating depression was directly studied in multiple double-blind clinical trials; both drugs exhibited promising safety profiles and similar efficacy rates in managing symptoms of depression.
A 2005 study comparing the two found that while there were no significant differences regarding their overall antidepressant effects, patients using Wellbutrin experienced fewer side effects related to sexual dysfunction, an advantage over Zoloft. This is likely due to its unique mechanism of action affecting dopamine levels rather than serotonin which can lead to this particular side effect.
According to a meta-analysis published in 2016, it seems that Wellbutrin may be more effective than placebo in treating depression, displaying similar efficacy compared with other common antidepressants including SSRIs like Zoloft. Nonetheless, Wellbutrin often serves as a third- or fourth-line treatment option —that's because it's generally considered only after SSRIs or first-line treatments have been tried without success. Much research relating to Wellbutrin involves its use co-prescribed alongside SSRIs as an augmentation strategy so data confirming its standalone efficacy is somewhat less robust compared to that for Zoloft.
Due to its unique pharmacology though, Bupropion might be an optimal treatment choice for those who didn't respond well enough to SSRI therapy or need something with lesser risk of triggering bothersome sexual side-effects.

At what dose is Wellbutrin typically prescribed?
Oral dosages of Wellbutrin range from 150-450 mg/day, although studies have shown that a dosage of 300 mg/day is often sufficient for treating major depressive disorder in most adults. However, children and adolescents could potentially be started on lower doses such as 75-100 mg/day. Dosage can be increased after several weeks if there is no response or if symptoms persist. The maximum dosage that should not be exceeded under any circumstances is 450 mg/day. Conversely, Zoloft's typical starting dose ranges from 50 to 200 mg per day for adults suffering from depression or obsessive-compulsive disorder (OCD). For children and adolescents with OCD, the initial recommended dose is typically around 25mg per day. As with Wellbutrin, it may take several weeks before improvement in symptoms are noticed and adjustments may need to made by your healthcare provider depending on individual needs and responses.
At what dose is Zoloft typically prescribed?
Zoloft treatment is typically initiated at a dosage of 50 mg/day. Depending on the patient's response, this dose can be increased to up to 200 mg/day, either as a single dose or divided into two doses taken in the morning and midday. The maximum permissible daily dosage is 200mg. A healthcare provider may consider increasing your initial dosage to this maximum level if there has been no significant improvement in symptoms after several weeks of therapy at lower doses. As with any medication regimen, it's crucial that patients adhere strictly to their healthcare provider's prescribed dosing instructions for Zoloft.
What are the most common side effects for Wellbutrin?
The most common side effects of Wellbutrin, an antidepressant that works by affecting the balance of chemicals in the brain, include:
- Dry mouth
- Nervousness
- Sweating
- Tremors (unintentional trembling or shaking)
- Insomnia (difficulty sleeping)
- Loss of appetite
- Constipation
- Weight loss
On the other hand, Zoloft is another type of antidepressant. Some of its possible side effects are:
- Nausea and vomiting
- Diarrhea or constipation
- Decreased appetite and weight loss
- Dizziness or lightheadedness
- Feeling tired or fatigued
- Sleep problems (insomnia)
- Increased sweating
- Sexual problems such as decreased libido, delayed ejaculation, impotence
Both drugs can also cause more serious side effects including severe allergic reactions. Always consult with a healthcare professional when considering these medications.
Are there any potential serious side effects for Wellbutrin?
While Wellbutrin is generally safe for most people, there are some potential serious side effects to be aware of:
- An increase in suicidal thoughts or tendencies, particularly in individuals under the age of 24.
- Signs of an allergic reaction such as hives, difficulty breathing, swelling of your face or throat. More severe skin reactions can include a red or purple skin rash that spreads and causes blistering and peeling.
- Eye problems including pain, changes in vision or swelling around the eyes.
- Heart issues such as fast heartbeats, fluttering in your chest (palpitations), shortness of breath and sudden dizziness - these could be signs of a life-threatening condition called Torsades de Pointes.
- Low sodium levels which can lead to headache, confusion, slurred speech, severe weakness and unsteadiness. In rare cases vomiting and loss of coordination may also occur.
- Serious nervous system response with symptoms like rigid muscles high fever sweating confusion uneven heartbeat tremors feeling light headed In extreme cases it might cause serotonin syndrome characterized by agitation hallucinations fever excessive sweating shivering rapid heart rate muscle stiffness twitching loss coordination nausea vomiting diarrhea
If you experience any adverse effects while taking Wellbutrin contact your healthcare provider immediately.
What are the most common side effects for Zoloft?
When comparing Wellbutrin to Zoloft, the potential side effects of Zoloft include:
- Dry mouth or increased salivation
- Indigestion, nausea, and loss of appetite
- Change in sleep patterns such as insomnia or drowsiness
- Sweating more than usual
- Feeling nervous or shaky (tremors)
- Faster heartbeat than normal
- Weight changes – either weight gain or weight loss
- Frequent urination
- Headache, dizziness, feeling weak or tired
-Muscle pain, stiffness, cramping. While some people may experience these symptoms when they start taking Zoloft; others may not. It's important to communicate with your healthcare provider about any new symptoms you are experiencing after starting a medication like this one.
Are there any potential serious side effects for Zoloft?
Zoloft, while highly effective for many people, can occasionally cause serious side effects. If you experience any of the following symptoms while on Zoloft, it's essential to seek immediate medical attention:
- Symptoms of an allergic reaction such as hives; difficulty breathing; swelling in your face or throat
- Severe skin reactions—fever, sore throat, burning eyes, skin pain or a red/purple rash that spreads and causes blistering/peeling
- Changes in mood or behavior—new/worsening depression/anxiety/panic attacks/trouble sleeping/agitation/hostility/restlessness/hyperactivity (both mentally and physically)/increased suicidal thoughts/attempts
- Unusual weight loss
- Irregular heartbeats
- Vision changes like blurred vision/tunnel vision/eye pain/swelling/redness/bright flashes/halos around lights/spots in your sight.
Remember to always consult with a healthcare professional if new side effects occur when starting a new medication.
Contraindications for Wellbutrin and Zoloft?
Both Zoloft and Wellbutrin, like many other antidepressant medications, may exacerbate symptoms of depression in certain individuals. If you observe that your depression is worsening or if there's an increase in suicidal thinking or behavior, it's crucial to seek immediate medical attention.
Neither Zoloft nor Wellbutrin should be taken if you are currently taking, or have recently taken monoamine oxidase (MAO) inhibitors. As always, inform your physician about all the medications you're taking; MAOIs require a period of approximately 5 weeks to be eliminated from your system in order to avoid harmful interactions with Zoloft and Wellbutrin.
How much do Wellbutrin and Zoloft 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 $16–32/day, depending on your dose.
- The price of 30 capsules of Zoloft (50 mg) is about $320, working out to approximately $10.67/day.
Thus, if you are in the higher dosage range for Wellbutrin (i.e., 300 mg/day or higher), then brand-name Zoloft is less expensive on a per-day treatment basis. Please note that cost should not be a primary consideration in determining which drug is right for you.
For generic versions:
-
Bupropion (Wellbutrin's generic form) costs vary widely but will usually run from around $0.25 to $0.80 per day for dosages at or below 100mg/day, and between roughly $.50 and $1.50 per day if your daily dose lies between 200 to as high as possibly even 450mg.
-
Sertraline (Zoloft's generic equivalent), available in packs ranging from just one pill up through quantities exceeding several hundred capsules/tablets with doses typically being either 25 or sometimes even slightly more than twice that amount at say perhaps something like maybe just over say fifty milligrams [or so] each; this medication typically costs anywhere from an incredibly low initial starting point already set at mere pennies ($.05) each single solitary day all way upward until reaching its absolute maximum upper limit estimated somewhere near closer towards ninety cents ($0.90).
Popularity of Wellbutrin and Zoloft
Bupropion, both in its generic form and under brand names such as Wellbutrin, was estimated to have been prescribed to approximately 5.8 million people in the US in 2020. Accounting for just over 12% of antidepressant prescriptions, bupropion is considered an "atypical" antidepressant because it does not fit into the broad classes like SSRI or SNRI but rather works by inhibiting dopamine and norepinephrine reuptake. The use of bupropion has generally increased since 2013.
Sertraline, sold under the brand name Zoloft among others, was prescribed to nearly 38.7 million people in the USA during that same time frame making it one of the most commonly used psychiatric medications. In America, sertraline accounts for roughly a quarter of all SSRI prescriptions and about 17% of overall antidepressant prescriptions demonstrating its high acceptance rate amongst healthcare providers due to its balanced efficacy and side effect profile compared with other SSRIs. Unlike bupropion's steady growth pattern within a decade period; interestingly enough there has been a marked increase in sertraline prescription rates from mid-2019 likely related to increasing mental health concerns induced by global issues.
Conclusion
Both Wellbutrin (bupropion) and Zoloft (sertraline) have long-standing records of usage in patients with depression, and are backed by numerous clinical studies indicating that they are more effective than placebo treatments. In some cases, the drugs may be combined, but this is subject to careful consideration by a physician as they can also interact with one another. Due to their different mechanisms of action - Wellbutrin primarily acting on norepinephrine and dopamine while Zoloft is a selective serotonin reuptake inhibitor (SSRI), they tend to be prescribed under different circumstances. Zoloft is often considered a first-line treatment option for depression and anxiety disorders due to its efficacy and tolerability profile; however, Wellbutrin may be preferable for patients who did not respond well to SSRIs or wish to avoid common SSRI-related side effects such as weight gain or sexual dysfunction.
Both drugs are available in generic form which represents significant cost savings especially for patients who must pay out of pocket. Both Wellbutrin and Zoloft may require an adjustment period where effects might not be noticeable right away.
The side effect profiles differ between the two drugs: both are generally well-tolerated but with Wellbutrin being less prone to induce sexual dysfunction compared to Zoloft. For both medications, it's essential that patients closely monitor their moods when starting treatment, particularly if depressive symptoms worsen or suicidal thoughts emerge which would warrant immediate medical attention.
