Signs and symptoms of drug overdosing

  • Dilated pupils.
  • Unsteady walking.
  • Chest pain.
  • Severe difficulty breathing, shallow breathing, or complete cessation of breath.
  • Gurgling sounds that indicate the person’s airway is blocked.
  • Blue lips or fingers.
  • Nausea or vomiting.
  • Abnormally high body temperature.
  • Violent or aggressive behavior.
  • Disorientation or confusion.
  • Paranoia.
  • Agitation.
  • Convulsions or tremors.
  • Seizures.
  • Unresponsiveness.
  • Unconsciousness

It's not necessary to have all the above signs or symptoms before you seek medical help. A person suffering from drug overdosing who is unconscious or can't be awakened is at risk of dying.

If you suspect that someone has overdosed — even if you don't see the classic signs and symptoms — seek immediate medical care.
