PACKAGE LEAFLET: INFORMATION FOR THE USER
1 million International Units (IU)
Powder for Nebuliser Solution
Promixin contains colistimethate sodium, and is given as an
inhalation to treat chronic chest infections in patients with cystic
fibrosis. Promixin is used when these infections are caused by
specific bacteria called Pseudomonas aeruginosa.
This is a very common bacteria that infects the lungs of nearly all
patients with cystic fibrosis at some time during their lives. If the
infection is not properly controlled it will continue to damage the
lungs, causing further problems.
Promixin is dissolved in sterile saline (salt water) or sterile water
and then breathed (inhaled) into the lungs so that more of the
antibiotic can target the bacteria causing the infection.
