4.4 Special Warnings And Precautions For Use
Although potentially serious allergic adverse reactions such as anaphylactic shock may occur rarely during, or shortly after, parenteral administration of Pabrinex Intramuscular, such rare occurrence of serious allergic reactions should not preclude the use of Pabrinex Intramuscular in patients who need treatment by this route of administration. Initial warning signs of a reaction to Pabrinex Intramuscular are sneezing or mild asthma, and those treating patients need to note that the administration of further injections to such patients may give rise to anaphylactic shock. Facilities for treating anaphylactic reactions should be available whenever Pabrinex Intramuscular High Potency is administered.
This medicine is for injection into a muscle only and should not be given by any other route
Care should be taken to ensure that the route of administration used (intramuscular or intravenous) is that intended – reports of unintentional administration by the wrong route have been received; these incidents have not been associated with serious adverse reactions.
