Solution for Injection
Dicobalt Edetate Injection is a specific antidote for acute cyanide poisoning. In
view of the difficulty of certain diagnosis in emergency situations, it is
recommended that Dicobalt Edetate Injection only be given when the patient is
tending to lose or has lost consciousness. The product should not be used as a
Posology and method of administration
Cyanide poisoning must be treated as quickly as possible and intensive
supportive measures must be instituted: clear airways and adequate ventilation
are essential. 100% oxygen should be administered concurrently with Dicobalt
Expert advice on the treatment of poisoning is available at the local poisons
One 300mg ampoule intravenously over approximately one minute. If the
patient shows inadequate response, a second ampoule may be given. If there is
no response after a further five minutes, a third ampoule maybe administered.
Each ampoule of Dicobalt Edetate Injection may be followed immediately by
50ml Glucose Intravenous Infusion BP 500g/l.

Special warnings and precautions for use
There is a reciprocal antidote action between cyanide and cobalt. Thus in the
absence of cyanide, Dicobalt Edetate Injection itself is toxic. It is therefore
essential that the product only be used in cases of cyanide poisoning. When
the patient is fully conscious, it is unlikely that the extent of poisoning
warrants the use of Dicobalt Edetate Injection.

anaphylactic type reaction, which may be dramatic. Oedema (particularly of
the face and neck), vomiting, chest pain, sweating, hypotension, cardiac
irregularities and rashes may occur.
Treatment - intensive supportive therapy is required.

Dicobalt Edetate Injection forms a stable complex with the cyanide thereby
acting as an antidote.
