Narcan Nasal Spray

Name: Narcan Nasal Spray

What is Narcan?

Narcan Nasal Spray contains naloxone hydrochloride. Naloxone blocks or reverses the effects of opioid medication, including extreme drowsiness, slowed breathing, or loss of consciousness. An opioid is sometimes called a narcotic.

Narcan Nasal Spray is used to treat an opioid overdose in an emergency situation. This medicine should not be used in place of emergency medical care for an overdose.

Narcan Nasal Spray is also used to help diagnose whether a person has used an overdose of an opioid.

Important information

In an emergency situation it may not be possible before you are treated to tell your caregivers about your health conditions or if you are pregnant or breast feeding. Make sure any doctor caring for you afterward knows that you have received this medication.

What happens if I overdose?

Since each spray pump contains only enough naloxone for one dose, an overdose is unlikely to occur.

What should I avoid while taking Narcan?

Avoid leaving a person alone after giving him or her a dose of Narcan Nasal Spray. An overdose can impair a person's thinking or reactions.
