How Long Does it Take for Wellbutrin (Bupropion) to Work? – When used as a treatment for depression, Wellbutrin (bupropion) usually takes around six to eight weeks before it starts fully working as a treatment for depression. However, you may begin to experience improvements in your sleep habits, appetite and energy levels as early as one to two weeks of treatment.
It may take four to six weeks to experience a significant improvement in your mood and level of interest in activities after starting bupropion. When used as a smoking cessation aid, typically under the name brand name Zyban, it can take several weeks for bupropion to start working, as well. Most people are advised to set a target “quit date” and start bupropion while they’re still smoking to give time for the medication to become effective.
Depending on your symptoms, general health and other factors, your healthcare provider may recommend that you take bupropion for seven to 12 weeks after you stop smoking.

What does it feel like when Wellbutrin starts working?
How Long Does it Take for Bupropion to Work? – Bupropion may take several weeks to begin functioning as a treatment for MDD, SAD, and nicotine addiction. Individuals may experience significant improvements to physical symptoms such as sleep patterns, appetite, and energy levels during the first couple of weeks of treatment.
However, it may take around four to six weeks to experience any noteworthy improvements in mood and interest in activities. Bupropion for MDD treatment may be required long after the symptoms are under control to prevent the depressive symptoms from re-emerging. In contrast, bupropion for SAD and smoking cessation is only required for a shorter period.
Since bupropion for nicotine addiction treatment takes several weeks to start working, most people are advised to establish a target “quit date” and start bupropion treatment while still smoking to give the medication enough time to take effect. Bupropion for smoking cessation is generally recommended seven to twelve weeks after quitting smoking to minimize withdrawal symptoms.

How do you know when Wellbutrin is working?
How long does it take Wellbutrin XL/SR (bupropion) to work? You may notice an improvement in your sleep, energy and appetite in the first week or two of taking Wellbutrin and this can be an important sign that the drug is working. But, like other antidepressants, improvements in your mood or motivation may take 6 to 8 weeks to develop and it may be a few months before you regain an interest in the activities you used to enjoy.
- Bupropion is metabolized to three active metabolites once in the body, each with varying durations of action, and it’s typical to notice a gradual improvement in your symptoms of depression over weeks to months.
- Is the brand name for the antidepressant drug,
- Wellbutrin and both work the same way.
- Wellbutrin weakly blocks nerve cells in the brain (neurons) from taking up the brain neurotransmitters norepinephrine and dopamine after these chemicals have been released in the brain.
Norepinephrine and dopamine are important for regulating mood and brain responses. Over time, taking Wellbutrin increases the amount of these neurotransmitters in the body, which may reduce symptoms of depression. Not everyone has the same symptoms of depression, but common ones include:
Feeling sad, empty and hopeless (depressed mood) Sleeping more or less than usual Eating more or less than usual No interest or pleasure in activities you usually enjoy Trouble concentrating Low energy Nervous energy.
The difference between Wellbutrin XL and SR is the way the drug is released in your body. XL is “extended release” and only needs to be taken once a day. SR stands for “sustained release” and may be taken twice a day, usually in the morning and afternoon.
Wellbutrin XL comes in 150 mg and 300 mg tablets. Wellbutrin SR is also a tablet and comes in doses of 100 mg, 150 mg and 200 mg. You can take Wellbutrin with or without food. Taking Wellbutrin can increase the risk of suicidal thoughts and behaviors, so close monitoring for these side effects is important.
Some people may also be at risk for a seizure from taking Wellbutrin, so it’s common to start on a low dose of the drug and increase it gradually over time for safety. This can also make it take longer for the drug to have its full effect. Even if you do not notice improvement in your depression symptoms, you should not stop taking Wellbutrin.
How long does Wellbutrin take to kick in during the day?
How Long Does It Take to See Results? – In contrast to stimulant medication, which starts to work in about an hour, like other antidepressants, Wellbutrin can take several days to produce noticeable benefits and up to six weeks to reach full effect. This means it can take several weeks to find the most effective therapeutic dose.
Why does Wellbutrin make me feel so good?
What is this medication? – BUPROPION (byoo PROE pee on) treats depression. It increases norepinephrine and dopamine in the brain, hormones that help regulate mood. It belongs to a group of medications called NDRIs. This medicine may be used for other purposes; ask your health care provider or pharmacist if you have questions. COMMON BRAND NAME(S): Wellbutrin
Does Wellbutrin dull your emotions?
Prevalence of Emotional Blunting – A study from the University of Oxford found that 46% of antidepressant users experienced emotional blunting during treatment. According to the research, the antidepressants most commonly associated with emotional blunting are:
- Selective norepinephrine reuptake inhibitors (SNRIs) such as Cymbalta (duloxetine), Pristiq (desvenlafaxine), and Effexor XR (venlafaxine)
- Selective serotonin reuptake inhibitors (SSRIs) like Lexapro (escitalopram), Prozac (fluoxetine), Zoloft (sertraline), and Paxil (paroxetine)
- Tricyclic and tetracyclic antidepressants like Elavil (amitriptyline) and Remeron (desvenlafaxine)
By and large, those who no longer needed antidepressants experienced a reversal of emotional blunting, confirming the role that these drugs play in this side effect. Though the percentage of people who experienced emotional blunting was similar between the three drug classes, there were variations.
- On the one end, 33% experienced emotional blunting while on Wellbutrin (bupropion) while, on the other end, 75% experienced the same effect on Cymbalta (duloxetine hydrochloride).
- Wellbutrin is a different class of drug known as a dopamine and norepinephrine reuptake inhibitor.
- Unlike the others, it does not target a chemical transmitter in the brain—known as serotonin—that all of the other drugs do.
This suggests that the inhibition of serotonin may be one of the prime causes of emotional blunting.
Can I drink coffee on Wellbutrin?
Wellbutrin interactions with food – Wellbutrin may interact with caffeine. Consuming too much caffeine while taking Wellbutrin can increase the risk of seizures. Examples of foods and beverages that contain caffeine include:
coffee tea chocolate energy drinks

If you’d like to learn more about eating certain foods during treatment with Wellbutrin, talk with your doctor. Note: Caffeine is also found in certain OTC drugs and supplements.

What does Wellbutrin do if you are not depressed?
Effects of Taking Antidepressants When Not Depressed – As is the case with most prescription medications, antidepressants are typically abused for one of two reasons:
To self-medicate To achieve a recreational high
Many people mistakenly believe that, since prescription medications are used by doctors to treat legitimate medical concerns, they are safer than other commonly abused substances. While it’s true that antidepressants and other prescription medications can be used with minimal risk when the person who is taking them follows their doctor’s instructions, every drug can cause unpleasant side effects.
- And when a person exceeds the recommended frequency and dosage levels of any medication, they can expose themselves to considerable harm.
- According to a 2014 article in the journal Substance Abuse and Rehabilitation, most people who abuse antidepressants have a substance use disorder (addiction) and a co-occurring mood disorder.
The typical reason people abuse antidepressants, this article reports, is because they are attempting to experience “a psychostimulant-like effect.” In the case of SSRIs, SNRIs, and related medications, the effects of taking antidepressants when not depressed can include developing a condition known as serotonin syndrome.
Confusion Agitation Restlessness Racing heart rate Impaired coordination Muscle rigidity Twitches, tremors, or spasms Severe headaches Excessive sweating Diarrhea
In some cases, serotonin syndrome can be life-threatening. Severe effects can include the following:
Delirium Hypertension Elevated body temperature Seizure Loss of consciousness
Initial symptoms of serotonin syndrome can begin to occur within 24 hours after a person has begun to take a dangerous amount of an SSRI, an SNRI, or another antidepressant that impacts serotonin levels. In mild or moderate cases, ending the use of these medications may often resolve the problem.
