What is Colomycin and for what it is used?
Colomycin is Colistimethate Sodium, an antibiotic that fights infections caused by Pseudomonas Aeruginosa.
Colomycin is breathed into the lungs (inhaled) so that more of the antibiotic can work against the bacteria causing the infection.
Before you take Colomycin
Tell your doctor if:
- You are pregnant or could get pregnant
- You are breast-feeding
- You are allergic (hypersensitive) to Colistimethate Sodium
- You suffer from myasthenia gravis (a rare disease where your muscles are extremely weak and get tired very quickly)
Take special care with Colomycin and tell your doctor if:
- You have or have had kidney problems
- You suffer from porphyria (a rare metabolic disease that some people are born with)
- If you have asthma
Using other medicines
Please tell your doctor or pharmacist if you are taking or have recently taken any other medicines, including medicines you bought without a prescription. These medicie may intefere with the effect of Colomycin.
- If you are taking antibiotics such as Cephalothin Sodium, Gentamicin, Amikacin, Netilmicin and Tobramycin, please tell your doctor. Taking Colomycin at the same time as these other antibiotics could increase your risk of kidney problems
- Colomycin could prolong the effects of muscle relaxing medicines, which may be used as part of a general anaesthetic if you have an operation. If you need to have a general anaesthetic, tell the anaesthetist that you are taking Colomycin
