How should I use naloxone nasal (Narcan)?
Follow all directions on your prescription label. Do not use this medicine in larger or smaller amounts or for longer than recommended.
This medicine may be given by a healthcare provider, emergency medical provider, or a family member or caregiver who is trained to properly give naloxone nasal.
Naloxone nasal should be sprayed into the nose while the person is lying on his or her back.
If you are a caregiver or family member giving naloxone nasal to another person, read all instructions when you first get this medicine. Read all caregiver information, medication guides, and instruction sheets provided with this medicine. Ask your doctor or pharmacist if you have any questions.
Be sure you know how to recognize the signs of an opioid overdose in the person you are caring for. Overdose symptoms may include:
- slowed breathing, or no breathing;
- very small or pinpoint pupils in the eyes;
- slow heartbeats; or
- extreme drowsiness, especially if you are unable to wake the person from sleep.
Even if you are not sure an opioid overdose has occurred, if the person is not breathing or is unresponsive, give naloxone nasal right away and then seek emergency medical care.
Do not assume that an overdose episode has ended if symptoms improve. You must get emergency help after giving naloxone nasal. You may need to perform CPR (cardiopulmonary resuscitation) on the person while you are waiting for emergency help to arrive.
After giving this medicine, stay with the person and watch for continued signs of overdose. You may need to give another dose every 2 to 3 minutes until emergency help arrives. Follow all medication instructions carefully.
Each single-use spray pump contains enough naloxone nasal for one use only. Throw away after one use, even if there is still some medicine left in the pump after using a dose.
Store at room temperature away from moisture and heat. Keep each spray pump in the box until you are ready to give a dose. Do not use this medicine if the expiration date on the label has passed.
What happens if I miss a dose (Narcan)?
Because you will receive naloxone in an emergency situation, you are not likely to miss a dose.
What happens if I overdose (Narcan)?
Since each spray pump contains only enough naloxone nasal for one dose, an overdose is unlikely to occur.
What should I avoid while taking naloxone nasal (Narcan)?
Avoid leaving a person alone after giving him or her a dose of naloxone nasal. An overdose can impair a person's thinking or reactions.
What other drugs will affect naloxone nasal (Narcan)?
Other drugs may interact with naloxone, including prescription and over-the-counter medicines, vitamins, and herbal products. Tell your doctor about all your current medicines and any medicine you start or stop using.
