A lot of people who are starting antidepressant treatment, they usually end up asking what kind of changes they might see in their body and mind. One of the meds that gets prescribed pretty often is Bupropion, which most people know as Wellbutrin.
At Uncover Mental Health Counseling in New York State, we try to help clients sort through what could happen with medications like Wellbutrin both in the short run and the long run, while also pairing that with therapy and more holistic mental health support.
What Is Wellbutrin (Bupropion)?
Wellbutrin is sort of an antidepressant that gets classified as a NDRI , meaning norepinephrine dopamine reuptake inhibitor.
And unlike SSRIs, it seems to work by pushing up the dopamine and norepinephrine activity in the brain, so it can end up influencing stuff like:
- Mood
- Motivation
- energy levels
- focus.
It’s typically prescribed for:
- major depressive disorder
- seasonal affective disorder (SAD)
- off label use for ADHD, or support with smoking cessation.
What Are the Most Common Wellbutrin Side Effects?
Side effects can feel pretty different from one person to another, especially in the early phase of treatment.
For a lot of people, the usual stuff is:
- Trouble sleeping, meaning insomnia
- Dry mouth
- Headache
- Nausea
- Dizziness
- More perspiration
- Tremors, or that shaky feeling
- A fast heartbeat
- Anxiety, or a restless vibe
These effects tend to be more noticeable when you first start the medication, or when the dose is being changed, basically at the beginning stages.
Wellbutrin Side Effects in the First Week
During that first week on Wellbutrin, a lot of people notice the most intense shift, like fairly quickly. It’s also around this time that most early side effects show up.
The most common early side effects are:
- Insomnia, or trouble keeping asleep
- Headaches
- Nausea, or general stomach discomfort
- Dry mouth
- Feeling “activated” , kind of restless
- More energy, or a jittery kind of vibe
Why it happens
Your brain is simply getting used to the higher dopamine and norepinephrine activity. For many people, this adjustment window is temporary.
One important insight though
Most of the side effects from week one start to ease up within about 1–2 weeks, especially if the dose is a good fit and you take it in the morning.
How Long Do Wellbutrin Side Effects Last?
For many people:
- First-week side effects: 1–2 weeks
- Adjustment period: 2–4 weeks
- Full therapeutic stabilization: 6–8 weeks
If side effects continue beyond this, it may be related to:
- Dosage being too high
- Timing of medication (e.g., taken too late in the day)
- Individual sensitivity
Wellbutrin Long-Term Side Effects

Wellbutrin is usually thought to be ok for long-term use , especially if someone is watching over it with a healthcare provider. That said, there are some “keep an eye on it” things that can come up later.
For possible long term effects, people sometimes notice:
- Some folks get increased blood pressure
- Insomnia can keep showing up if it’s taken too late in the day
- Certain users may still have anxiety or irritability, even after things settle a bit
- Weight changes can happen , and it really depends on the person
Then there are the less common but still important risks, like:
- Seizures , where the risk is higher at higher doses or if there are certain underlying conditions
- Mood swings or mood instability in people who are more vulnerable
Regular follow ups with your provider are really important, not just once in a while but consistently, to check safety and whether it’s still working well.
Does Wellbutrin Affect Anxiety?
Wellbutrin can mess with anxiety in sort of different ways, depending on the person, sometimes it helps.
In some cases it may:
- improves motivation and gives more push for energy
- it can reduce depressive symptoms that are kinda feeding into the anxiety
For some people, they also:
- create jitteriness, or that restless feeling
- temporarily heighten anxiety during early treatment, like your body needs to adapt.
So this is why dosage levels, and close monitoring really are essential for the first few weeks.
Does Wellbutrin Affect Sexual Function?
Unlike a lot of antidepressants, Wellbutrin tends to be less likely to bring sexual side effects along with it. In some cases , it might even help
- boost libido
- kind of counteract sexual side effects that can show up with SSRIs
That’s why it’s often used as a common alternative, or sometimes as an add-on in depression care.
Wellbutrin Drug Interactions
Wellbutrin can interact with some other meds, including:
- antidepressants (SSRIs,SNRIs, MAOIs)
- seizure medications
- antipsychotics
- certain heart medications
- HIV medications
Before you start treatment, always tell your provider about every medication and supplement you take , just to be safe.
Who Should Avoid Wellbutrin?
Wellbutrin may not be suitable for individuals with:
- Seizure disorders
- Eating disorders (bulimia or anorexia)
- Heavy alcohol use with abrupt withdrawal risk
- Recent MAOI antidepressant use
A full medical evaluation is necessary before starting treatment.
When do you need to contact a healthcare provider?
You should reach out for medical help if you notice any of these symptoms:
- severe agitation, or intense anxiety
- thoughts about suicide
- hallucinations, or signs of mania
- seizures
- a severe rash or an allergic response
- notable blood pressure changes
These reactions are uncommon but they still need prompt attention.
How Therapy Helps Alongside Medication
Medication like Wellbutrin can help kind of nudge brain chemistry into better balance, but therapy tends to go after the deeper emotional and cognitive patterns that sit underneath depression and anxiety. In other words, one helps with the symptoms while the other helps with the root stuff.
