WHAT IS NALOXONE?

Naloxone is a medicine which, when injected, reverses the effect of opium-like substances such as morphine, heroin and codeine. It acts very quickly and can be a life saving measure in those people who have received an overdose of a narcotic drug.

WHEN IS NALOXONE USED?

Naloxone is used in any situation where it is necessary to reverse the effects of opium and its derivatives, such as morphine, heroin and codeine.

Naloxone is used after surgical operations when powerful pain killers have been given and are no longer required when the operation is over.

Naloxone is the standard treatment for those who have received an overdose of heroin or similar drugs. Naloxone acts very quickly and is often lifesaving in such cases. It is also used in new-born infants whose mothers have received opium-like drugs.

As naloxone is only used in medical emergencies, injection may be given by paramedical personnel such as ambulance or nursing staff.

SIDE EFFECTS OF NALOXONE

As with any medicine, some side effects may occur.

Nausea, vomiting, sweating and palpitations sometimes occur after an injection of naloxone, particularly if it is given after an anaesthetic.

When naloxone is given to someone who has taken an overdose of heroin or similar drug, it can produce overbreathing and tremor. On rare occasions the treated person has had a fit but this may not have been due to the naloxone.

People who have been given naloxone after having received large doses of heroin or similar drugs may suffer the severe problems associated with sudden drug withdrawal.

Patients with heart disease can sometimes be made worse following naloxone. Alterations in blood pressure and abnormal heart rhythms have occurred.

Always tell your doctor if you have any unpleasant effects after receiving a Naloxone Hydrochloride Injection MIN-I-JET.

THE DOSE OF NALOXONE

The dose varies depending on the reason for which it is being used and the age of the patient.
