With Wellbutrin, avoid MAOIs, linezolid or methylene blue, seizure-threshold–lowering drugs, and heavy alcohol; check CYP2D6 interactions.
You’re here to sort out what not to take with wellbutrin so you can stay safe and keep the medicine working as intended. This guide lays out clear no-go combinations, risky pairings that need extra care, and simple steps to check your own list before a refill or a procedure. Every section lists the why and the what to do instead, backed by official sources.
What Not To Take With Wellbutrin? Quick List By Risk
Start with the strict do-not-combine group, then scan medicines that raise seizure risk, then look at drugs affected by bupropion’s enzyme blocking effect. If a drug sits in more than one bucket, treat it as high risk. Always share your full list with your prescriber.
| Do Not Combine | Why | What To Do Instead |
|---|---|---|
| MAOIs (phenelzine, tranylcypromine, isocarboxazid) | Hypertensive reactions; must separate by 14 days | Use a different antidepressant; wait required washout |
| Linezolid or IV methylene blue | MAOI activity raises risk of dangerous reactions | Hold bupropion; resume 24 hours after last dose |
| Other bupropion products (Zyban, Aplenzin, Contrave) | Stacked doses raise seizure risk | Keep only one bupropion-containing product |
| Current seizure disorder | Bupropion itself can provoke seizures | Use another antidepressant class |
| Bulimia or anorexia nervosa | Higher seizure rate in these conditions | Choose a non-bupropion option |
| Stopping alcohol, benzos, barbiturates, antiepileptics abruptly | Withdrawal lowers seizure threshold | Taper under medical supervision |
Source notes: The FDA label lists these as contraindications or strict precautions, including the 14-day MAOI rule and the linezolid and methylene blue restriction. Blood pressure spikes are also documented when bupropion pairs with nicotine patches in some patients.
Why These Interactions Matter
Bupropion boosts norepinephrine and dopamine and can raise seizure risk in a dose-dependent way. It also blocks the liver enzyme CYP2D6, which can raise levels of certain medicines or blunt the effect of drugs that need activation by CYP2D6. Some antibiotics and dyes act like MAOIs, which makes a dangerous mix.
Medications And Substances That Raise Seizure Risk
This group includes drugs and situations that lower the seizure threshold. The risk stacks with dose and with personal factors like head injury, electrolyte problems, or heavy alcohol use. Go slow on dose increases and flag these to your prescriber.
Common Culprits
Other antidepressants and antipsychotics, theophylline, systemic steroids, tramadol, illicit stimulants, and misuse of prescription stimulants can all push risk higher. Excess alcohol, diabetes treated with insulin or sulfonylureas, and abrupt sedative withdrawal also add risk.
What To Do In Real Life
Ask whether the combination is needed, whether the dose can be split or reduced, and whether a safer alternative exists. If tramadol or theophylline is on your list, ask about non-seizure-provoking options for pain or asthma control. Keep alcohol low, and never stop sedatives on your own. Mayo Clinic also advises limiting or avoiding alcohol to reduce seizure risk while on bupropion.
Do Not Pair With MAOIs, Linezolid, Or Methylene Blue
MAOIs clash with bupropion. The label requires a 14-day gap both ways to prevent hypertensive reactions. Linezolid and intravenous methylene blue act like MAOIs; the label says to stop bupropion and resume 24 hours after the last dose if these are needed for infection or a diagnostic dye. See the FDA prescribing information for the exact wording.
The UK regulator has also logged cases of serotonin syndrome when bupropion was taken with serotonergic drugs, which supports extra caution if you already use SSRIs, SNRIs, or triptans; see the MHRA drug safety update.
CYP2D6 Blockade: Medicines That Can Build Up
Bupropion and its metabolites inhibit CYP2D6. Levels of certain antidepressants, antipsychotics, beta-blockers, and Class 1C antiarrhythmics can rise, and tamoxifen can lose effect because it needs CYP2D6 to form its active metabolite. Doses may need adjustment or a different choice.
Drugs Often Affected
Venlafaxine, nortriptyline, imipramine, desipramine, paroxetine, fluoxetine, sertraline, haloperidol, risperidone, thioridazine, metoprolol, propafenone, flecainide, and tamoxifen appear on the list. Some NHS guidance advises avoiding the tamoxifen and bupropion combo due to reduced active metabolite levels.
Practical Checks
Open your medication list and circle any drug on the list above. If you see tamoxifen, talk about switching the antidepressant to one that doesn’t block CYP2D6. If you see a TCA, SSRI, or antipsychotic, ask if a dose trim or level check is sensible.
Nicotine Patches: Watch Blood Pressure
Combining bupropion with nicotine patches can raise the chance of treatment-emergent hypertension in a minority of people, especially if blood pressure was already high. The label suggests checking blood pressure during the combo; most people finish treatment without trouble when monitored.
Alcohol: Keep It Low And Never Quit Abruptly
Alcohol can magnify neuropsychiatric effects and seizure risk while you take bupropion. Some patients report lower alcohol tolerance on the medicine. Limit or avoid alcohol, and if you drink heavily, don’t stop suddenly without a plan, as withdrawal itself raises seizure risk.
Cold And Cough Mixes: Dextromethorphan, Antihistamines, And More
Many over-the-counter cold products combine dextromethorphan with antihistamines and decongestants. While bupropion is not strongly serotonergic, stacking dextromethorphan with other serotonergic drugs can cause trouble. If you already take an SSRI with bupropion, pick a plain product and skip multi-symptom syrups unless cleared by your clinician.
What About Food, Coffee, And Nicotine Gum?
No routine food restrictions apply. Coffee is fine for many people, but high caffeine intake can worsen jitteriness and sleep loss that already show up with bupropion. If you use nicotine gum along with a patch, keep your care team in the loop and monitor blood pressure during combined tobacco-cessation aids.
Checklist: Before You Start Or When Your List Changes
Run These Steps
1) Write down every prescription, supplement, and OTC product you use. 2) Flag MAOIs, linezolid, methylene blue, and other bupropion-containing products. 3) Circle seizure-threshold–lowering drugs and sedatives. 4) Scan for CYP2D6 substrates, especially tamoxifen and selected antidepressants or antiarrhythmics. 5) Share the list at each visit.
Know The Names
Brand names can hide duplicate bupropion. Wellbutrin, Wellbutrin SR, Wellbutrin XL, Zyban, Aplenzin, and the naltrexone-bupropion combo for weight management all contain bupropion or its salt. Only one should be on your profile at a time unless a specialist has a plan.
Close Variation: Medicines To Avoid With Wellbutrin (Rules That Apply)
This section restates what not to take with wellbutrin in plain terms. If you take or need any item below, pause and talk before the next dose: MAOIs; linezolid; intravenous methylene blue; other bupropion-containing products; drugs that lower seizure threshold; and any CYP2D6 substrate with a narrow window.
Edge Cases Worth Flagging
Dextromethorphan-Bupropion Combo Product
A newer cough-suppressant combination with bupropion exists for specific indications. Because it already includes bupropion, you wouldn’t combine it with Wellbutrin. Labels warn about interactions with MAOIs and alcohol, just like other forms of bupropion.
Levodopa Or Amantadine
Dopamine agonist effects can add up. Reports describe restlessness, tremor, ataxia, and dizziness when combined. If your neurologist prefers to keep bupropion, dose changes and symptom checks can help.
Table: CYP2D6 Substrates Commonly Affected
| Drug Or Class | What Can Happen | Practical Tip |
|---|---|---|
| Paroxetine, fluoxetine, sertraline | Higher levels and side effects | Use lower doses; watch for side effects |
| TCAs (nortriptyline, imipramine, desipramine) | Higher levels; anticholinergic effects | Level checks or pick a different antidepressant |
| Venlafaxine | Level rise; blood pressure changes | Monitor symptoms and pressure |
| Antipsychotics (haloperidol, risperidone) | Higher levels; movement effects | Use lowest dose that works |
| Metoprolol | Bradycardia, fatigue | Switch beta-blocker or trim dose |
| Flecainide, propafenone | Arrhythmia risk if levels climb | Cardiology input; consider alternatives |
| Tamoxifen | Reduced activation; less effect | Pick an antidepressant that spares CYP2D6 |
These examples come from the Wellbutrin SR label and prescribing guidance that cites CYP2D6 inhibition and the impact on selected substrates. Tamoxifen deserves special attention due to reduced activation.
Red Flags That Need A Call Today
Seizure, fainting, racing heartbeat, steep blood pressure rise, severe rash, confusion, or new manic symptoms need urgent care. If you started a new antibiotic or cough syrup and feel strange soon after, call. Do not skip the next dose until your prescriber clears the combination.
How To Talk To Your Care Team
Keep it short and direct: “I’m on bupropion. I use these other medicines and supplements. Any issues here?” Bring your list. Ask whether to space dosing, switch a drug, or order a level check. Ask how to handle alcohol and nicotine replacement while you use bupropion. Ask about level checks for TCAs or antiarrhythmics, and write down any dose changes, timing notes, and symptoms to watch during the first weeks.

Frequently Asked Questions
Can I Use Cold Medicine While Taking Bupropion?
Pick single-ingredient products when possible. If you already take an SSRI with bupropion, avoid multi-symptom syrups that add dextromethorphan without a green light from your clinician. Check labels for pseudoephedrine if you have blood pressure concerns and track any sleep changes.
Is There A Safe Gap If I Need Linezolid For An Infection?
Yes, bupropion should be stopped before starting linezolid. Resume bupropion 24 hours after the last linezolid dose. That timing comes from the label and aims to reduce hypertensive reactions and neurologic events linked to MAOI activity.
Do I Need To Stop Coffee?
No, but heavy caffeine can worsen jitteriness and sleep trouble. If you notice more palpitations or restlessness after your morning cup, reduce the amount or move the dose earlier in the day. Many people can keep one cup without any issues.
What If I’m Using A Nicotine Patch?
The combo can raise blood pressure in a small share of users. Check your pressure during treatment, especially if it runs high. If your readings climb or headaches kick in, call your prescriber. Most people do well with monitoring and a modest patch dose.
Does Grapefruit Interact With Bupropion?
Grapefruit affects CYP3A; bupropion is mainly handled by CYP2B6 and blocks CYP2D6. No clear grapefruit warning appears on the label. If your list includes other drugs with grapefruit issues, follow the caution for those medicines.
Wrapping It Up – What Not To Take With Wellbutrin?
When people ask what not to take with wellbutrin, the short list is clear: MAOIs, linezolid, intravenous methylene blue, duplicate bupropion products, and drugs or situations that push seizure risk higher. CYP2D6 inhibition brings a second layer that calls for dose changes or different picks for several antidepressants, antipsychotics, beta-blockers, antiarrhythmics, and tamoxifen.
Link your choices to the goal you care about: mood steadiness, tobacco cessation, or long-term prevention. Keep alcohol low, space out caffeine if needed, and check blood pressure if you add a nicotine patch. Two simple habits make the biggest difference—carry an updated list and ask before adding or stopping a medicine. You’ll avoid the traps that lead to side effects, ER visits, or stalled treatment.
