Seek help immediately if
- Chest pain; racing, pounding, or irregular heartbeat
- Very high body temperature; heavy sweating; hot, flushed skin
- Severe agitation, paranoia, panic, or confusion
- Severe headache; muscle rigidity or twitching
- Seizures
- Signs of stroke — face drooping, one-sided weakness, slurred speech
- Difficulty breathing; collapse or unconsciousness
What to do
- Call emergency services for chest pain, overheating, seizure, or unresponsiveness
- Move them to a cool, quiet place and reduce stimulation
- Cool the body — remove excess clothing, apply cool damp cloths, fan them
- Keep them calm; reassure — panic worsens the cardiovascular strain
- If seizing, protect from injury (don't restrain); recovery position afterward
- Monitor breathing and be ready to give rescue breaths / CPR
Most stimulant overdoses settle with cooling, a calm environment, and time. The medical danger is hyperthermia, cardiac events (arrhythmia, heart attack, stroke), and seizures — get help immediately if any appear.
