How Long to Stop Bupropion Before Taking MDMA
You should discontinue bupropion at least 14 days before taking MDMA to minimize serious drug interactions and cardiovascular risks.
Rationale Based on Evidence
The FDA drug label explicitly states that at least 14 days should elapse after stopping bupropion before starting an MAOI 1. While MDMA is not technically an MAOI, it shares critical pharmacological properties that create dangerous interactions with bupropion.
Why 14 Days is Critical
Bupropion inhibits dopamine and norepinephrine reuptake, and MDMA releases these same neurotransmitters through the same transporters 2. When combined, research demonstrates that:
- Bupropion increases plasma MDMA concentrations and prolongs subjective effects 2
- MDMA increases plasma bupropion concentrations 2
- This bidirectional pharmacokinetic interaction creates unpredictable drug levels of both substances
Cardiovascular Considerations
Interestingly, bupropion actually reduced MDMA-induced heart rate elevation and norepinephrine release in controlled studies 2. However, this should not be interpreted as protective—the enhanced mood effects and prolonged duration with elevated drug concentrations of both substances pose significant risks including:
- Seizure risk (bupropion lowers seizure threshold) 3
- Unpredictable neuropsychiatric effects
- Serotonin syndrome-like reactions
- Hypertensive crisis potential
Tapering Considerations
If you are on 300 mg daily, taper to 150 mg daily before complete discontinuation 1. This reduces withdrawal symptoms and seizure risk during the discontinuation process.
Practical Timeline
- Week 1: Reduce from 300 mg to 150 mg daily (if applicable)
- Week 2: Stop bupropion completely
- Weeks 3-4: Allow 14-day washout period
- After Day 14: Earliest safe timepoint for MDMA use
Critical Warnings
Bupropion is contraindicated with MAOIs due to hypertensive reaction risk 1. MDMA's mechanism of releasing monoamines creates similar pharmacodynamic concerns. The 14-day washout allows bupropion and its active metabolites to clear sufficiently to reduce interaction severity.
Do not attempt to use MDMA while on bupropion therapy—the research clearly shows both drugs' plasma concentrations increase unpredictably, and the prolonged subjective effects suggest dangerous accumulation 2.
