The person may not realize what has happened. They may be agitated or upset because they come out of the overdose feeling sick. Always stay with someone who has come out of an overdose. Depending on how much of a substance the person used, they could re-overdose after the administration of naloxone. Do your best to stay calm and keep the person company while waiting for emergency medical personnel. Encourage the individual to seek treatment and give them hope for recovery. Treatment works and recovery is possible!
