Know the risks

You are at increased risk of harm if you:

take multiple MDMA (ecstasy) tablets or capsules
take a higher-dose MDMA tablet or capsule
use multiple stimulant drugs (e.g., MDMA, synthetic cathinones, amphetamines or cocaine) at the same time
take MDMA in a hot environment like a music festival or indoor dance party.

The effects of taking both MDMA and dipentylone, and how fast or slow they come on, may differ to MDMA alone. If you’re not feeling the effects yet, don’t re-dose.
The dose in a tablet or capsule can vary a lot, even within the same batch.
High-dose MDMA use has been linked to death and other serious harms.

Effects to look out for

Feeling really hot and sweaty.
Racing heart/pulse or light-headedness.
Rigid muscles (e.g., difficulty walking), uncontrolled repetitive movements, seizures.
Confusion or agitation, feeling aggressive, difficult to rouse or unconscious.
Vomiting.

If you or others experience these symptoms, get help immediately.

Getting help

If you or your friends see the warning signs of overdose:

Seek help immediately from your nearest emergency department or call Triple Zero (000). You won’t get into trouble for seeking medical care.
Start CPR if someone is not responsive.
