1. WHAT NALOXONE INJECTION/INFUSION IS AND WHAT IT IS USED FOR
Naloxone belongs to a group of medicines known as opioid antagonists. Opioid medicines are strong painkillers such as morphine and codeine. In high doses these painkillers can result in side effects which cause difficulty in breathing and drowsiness. These effects can be reversed by an opioid antagonist (blocks the effects of opioids).
Naloxone Injection/Infusion may be used:
• to treat the breathing problems caused by these opioid painkillers
•to help determine whether a patient has taken or received an overdose of opioid drugs
• to reverse the depressant effects on breathing and on other parts of the brain and spinal cord in newborn infants (resulting from the use of opioid painkillers in the mother during childbirth).
2. BEFORE YOU ARE GIVEN NALOXONE INJECTION/INFUSION
You should not be given this medicine if you know that you are allergic to naloxone, or to any of the other ingredients (listed in Section 6 at the end of this leaflet).
Speak to your doctor if this applies to you before you are given this medicine.
Your doctor will take special care if:
• you have received large doses of opioid drugs or if you have a drug-dependence (drug addiction) problem
• you suffer from any heart or circulatory problems
•you suffer from high blood pressure, irregular heart beat or difficulty in breathing
• you have a newborn baby who requires this injection/infusion; tell the doctor beforehand if you received large doses of opioid drugs before you gave birth or if you have a drug-dependence problem
• you are suffering from diseases of the kidney, liver or lung.
Speak to your doctor if one of these applies to you before you are given this medicine.
Taking other medicines:
Tell your doctor before you are given this medicine if you are taking or have recently taken any other medicines, including medicines obtained without a prescription.
A number of medicines can interact with Naloxone Injection/Infusion which can significantly alter their effects. In particular, tell your doctor if you are taking

• Sleeping pills
• Medicines that may affect your heart or blood circulation (e.g. antihypertensive drugs, cocaine, methamphetamine, cyclic antidepressants, calcium channel blockers, beta-blockers, digoxin and clonidine) even those not prescribed.
