MDMA and Tramadol, contraindicated.
MDMA releases and blocks reuptake of serotonin, and tramadol also inhibits serotonin reuptake while lowering the seizure threshold. Combining them can sharply increase the risk of serotonin syndrome, hyperthermia, seizures, dangerous blood pressure changes, and overdose. This is a high-risk pairing even when either substance is used only once.

What is happening. MDMA releases and blocks reuptake of serotonin, and tramadol also inhibits serotonin reuptake while lowering the seizure threshold. Combining them can sharply increase the risk of serotonin syndrome, hyperthermia, seizures, dangerous blood pressure changes, and overdose. This is a high-risk pairing even when either substance is used only once.
Mechanism. MDMA is a monoamine releaser and uptake inhibitor with strong serotonergic effects. Tramadol inhibits serotonin reuptake and can provoke seizures; overlapping serotonergic and pro-convulsant effects increase toxicity risk.
Recommendation. Do not combine MDMA with tramadol. Avoid tramadol after MDMA exposure until you have medical guidance, especially if you have overheating, agitation, tremor, diarrhea, confusion, or muscle rigidity. Seek emergency care for fever, seizure, severe agitation, or altered consciousness.
