WHAT METHYLTHIONINIUM CHLORIDE PROVEBLUE IS AND WHAT IT IS USED FOR
Methylthioninium chloride (also called methylene blue) belongs to a
group of medicines called
antidotes.
Methylthioninium chloride Proveblue will be given to you or your child
(0-17 years old) to treat
problems with your blood resulting from exposure to some medicines or
chemicals that can cause a
disease called methaemoglobinaemia.
In methaemoglobinaemia, your blood contains too much methaemoglobin
(an abnormal form of
haemoglobin that is not able to transport oxygen around your body
effectively). This medicine will
help your haemoglobin return to normal and restore the transport of
oxygen in the blood.

POSOLOGY AND METHOD OF ADMINISTRATION
Methylthioninium chloride Proveblue
is for administration by a healthcare professional.
Posology
_ _
_Adults _
_ _
The usual dose is 1 to 2 mg per kg body weight, i.e. 0.2-0.4 ml per kg
body weight, given over a
period of 5 minutes.
A repeat dose (1 to 2 mg/kg body weight, i.e. 0.2-0.4 ml/kg body
weight) may be given one hour after
the first dose in cases of persistent or recurrent symptoms or if
methaemoglobin levels remain
significantly higher than the normal clinical range.
Treatment does not usually exceed one day.
The maximum recommended cumulative dose for the course of treatment is
7 mg/kg and should not be
exceeded, since Methylthioninium chloride administered above the
maximum dose may cause
methaemoglobinaemia in susceptible patients.
In the case of aniline- or dapsone-induced methaemaglobinaemia, the
maximum recommended
cumulative dose for the course of treatment is 4 mg/kg (see section
4.4).
Too limited data are available to support a continuous infusion dose
recommendation.
