An azo dye with analgesic effects on the urinary tract mucosa.
One of its metabolites is paracetamol.
It may discolour body fluids orange.
Oral administration 3 times a day.
Since the last update we have not found any published data on its excretion in breast milk.
It may cause kidney damage (Singh 2014) and methemoglobinemia (Banimahd 2016, Gold 2003).
There are few studies on its pharmacokinetics and it has limited efficacy.
Until there is more published data on this drug in relation to breastfeeding, safer known alternatives may be preferable, especially during the neonatal period and in cases of prematurity or glucose-6PD deficiency.
