In March 2025, the Department for Health and Social Care (DHSC) issued a National Patient Safety Alert for the discontinuation of the antibiotic Promixin.
Promixin is the brand name of colistin, or colistimethate, an antibiotic used to treat Pseudomonas aeruginosa lung infection. It is taken with the I-neb nebuliser.
The alert states that Promixin supplies are expected to run out by May 2025. I-neb consumables are also due to become unavailable by this date. This follows the discontinuation of the I-neb nebuliser device in May 2024.
