MDMA Emergencies: How to Spot One and Respond
A calm, practical emergency guide: the signs that mean call for help now, exactly what to do for each one, the recovery position, what to say to responders, and the mistakes that cost lives.
🚨 Call emergency services now
if someone is very hot to the touch, confused or disoriented, having a seizure, vomiting repeatedly, becoming rigid or twitching, has chest pain or a racing heart, or will not wake up. Say exactly what was taken. Delay is the single biggest factor in fatal outcomes - when in doubt, call.
The hardest part of an emergency is admitting it is one. People hesitate because they are scared of getting in trouble, or they tell themselves it will pass. That hesitation is the dangerous part. Emergency responders are there to help, not to police, and the difference between a scare and a tragedy is almost always how quickly help arrives.
This page is for the moment you need it. Read it once now so it is familiar, and come back to it if something goes wrong.
Emergency numbers
- United States and Canada: 911
- United Kingdom and Ireland: 999 (112 also works)
- Europe: 112 (works across the EU)
- Australia: 000
If you are somewhere else, look up your local emergency number before the night starts and save it. In many places, medical-amnesty or Good Samaritan protections exist so that calling for help does not get you or the person in trouble - but even where you are unsure, the person's life comes first. Call anyway.
First, is it actually an emergency?
Most hard moments on MDMA are not emergencies. Anxiety, a wave of fear, feeling overwhelmed, mild nausea, or a racing mind usually pass with a calm space, a steady voice, and time. What turns a hard moment into an emergency is the body being in danger - temperature, water balance, the heart, the brain.
The rule of thumb: if the problem is in their mind and mood, be a calm sitter (below). If the problem is in their body - heat, consciousness, breathing, heartbeat, seizures - treat it as an emergency and call.
The emergencies, and what to do
Overheating (hyperthermia)
The most common way MDMA kills, especially in hot, crowded spaces. Body temperature climbs faster than the body can shed it.
Signs: very hot skin, heavy sweating that may suddenly stop, confusion, cramping, feeling faint, a pounding heart.
Do:
- Move them somewhere cool and quiet immediately.
- Remove extra clothing.
- Cool the skin with cool (not ice-cold) water and move air over them - fan them, find airflow.
- Put cool, damp cloths or cold packs on the neck, armpits and groin.
- Get them sipping water if they are fully alert.
- Call for help if they are confused, not improving, or getting worse.
Don't: don't push them to keep dancing "to sweat it out," and don't plunge someone who is confused or drowsy into a cold bath - rapid shock is dangerous and they could aspirate.
Hyponatremia (too much water)
The opposite mistake, and a well-known cause of death because it comes from trying to be safe. Drinking large amounts of plain water dilutes the body's sodium, and the brain swells.
Signs: headache, nausea, confusion, disorientation, drowsiness, and swelling - usually after drinking a lot of plain water, and often in someone who has not been sweating much.
Do:
- Stop giving plain water.
- If they are fully alert and able to swallow safely, salty snacks or an electrolyte drink can help.
- Get medical help for anyone confused, drowsy, or vomiting - this needs a hospital, not another bottle.
Don't: don't give more plain water, and don't assume "drink more" is always right. For hyponatremia, more water makes it worse.
Serotonin syndrome
A dangerous overload of serotonin, most often when MDMA is mixed with other serotonergic drugs (antidepressants, MAOIs, tramadol, some others). It can escalate quickly.
Signs: agitation, confusion, a high temperature, a racing heart, heavy sweating, shivering, tremor, and muscles that are rigid, twitching or jerking.
Do: call emergency services, start cooling them as for overheating, keep them calm, and tell medics exactly what was taken and when. This is a medical emergency - it does not wait.
A cardiac event
MDMA raises heart rate and blood pressure and strains the heart, especially stacked with other stimulants or in someone with an underlying condition.
Signs: chest pain or tightness, a very fast or irregular heartbeat that will not settle, breathlessness, fainting.
Do: call emergency services, help them sit down and stay still and calm, and stay with them. Do not let them walk it off.
A seizure
Signs: sudden collapse with stiffening, jerking, or loss of awareness.
Do:
- Clear space around them and cushion their head.
- Do not restrain them and do not put anything in their mouth.
- Time it if you can.
- When the jerking stops, roll them into the recovery position (below).
- Call emergency services if it lasts more than 5 minutes, if it is their first seizure, if they have another, or if they do not come round.
Collapse - they will not wake up
Do:
- Try to rouse them - speak loudly, gently shake the shoulders.
- If they do not respond, check they are breathing.
- If they are breathing, put them in the recovery position and call emergency services.
- If they are not breathing normally, call emergency services immediately and start CPR - the dispatcher will talk you through it. Follow their instructions and do not hang up.
The recovery position
For anyone unconscious but breathing, this keeps their airway open and stops them choking if they vomit:
- Kneel beside them. Place the arm nearest you out at a right angle, palm up.
- Bring their far arm across the chest and hold the back of their hand against their nearer cheek.
- With your other hand, lift their far knee and roll them toward you onto their side.
- Tilt the head back slightly so the airway stays open, and check they are still breathing.
- Stay with them and keep checking until help arrives.
How to call for help
Staying on the line and giving clear information saves time. Tell them:
- Where you are - a precise location, entrance, or landmark. This matters most.
- What was taken - the substance, roughly how much, and when. Be honest; it changes the treatment. Responders are not there to arrest anyone.
- The symptoms - especially temperature, consciousness, breathing, and heartbeat.
- Their age, and anything else you know (other drugs, medications, conditions).
Then send someone to meet the ambulance and guide them in, and keep the phone with you.
Being a sitter
If you are looking after someone through a hard moment, your job is calm presence:
- Stay with them - do not leave them alone.
- Move them somewhere cooler, quieter, and less stimulating.
- Reassure in a steady, low voice. Remind them it is the drug, it is temporary, and it will pass.
- Offer small sips of water, not floods.
- Keep watching for the physical warning signs above.
Most anxiety and overwhelm settle with space, time, and a steady person beside them. Your other job is to know where the line is - the moment a hard moment becomes one of the emergencies above, stop sitting and start calling.
What not to do
- Don't leave them alone to "sleep it off" if anything is wrong.
- Don't wait to see if it passes when the danger signs are there. Delay is what kills.
- Don't give more plain water to someone who may have hyponatremia.
- Don't put a drowsy or confused person in a cold bath, and don't try to make them vomit.
- Don't let fear of trouble stop you calling. No consequence compares to losing someone.
Educational only, not medical advice, and no substitute for trained first aid or professional care. If you can, take a basic first-aid or CPR course - it is the single most useful thing you can carry into any night out. In an emergency, call your local emergency number immediately.
