If the patient thinks that he/she has given him/herself too much Colomycin, he/she should contact the doctor or nurse immediately for advice or, if they are not available, contact or go to the nearest hospital accident and emergency department. If too much Colomycin is accidentally given, the side effects can be serious and can include kidney problems, muscle weakness and difficulty (or even stopping) breathing.
If the patient is being treated in hospital or at home by a doctor or nurse and think that he/she may have missed a dose or been given too much Colomycin, please ask the doctor, nurse or pharmacist about this.
