Like all medicines, this medicine can cause side effects, although not everybody gets them.
Allergic reactions: Whether Colomycin is given into a vein or by inhalation, an allergic reaction is possible. Serious allergic reactions can happen even with the very first dose and can include rapid development of rashes, swelling of the face, tongue and neck, inability to breathe due to narrowing of the airways and loss of consciousness.
If the patient experiences signs of an allergic reaction he/she should seek urgent medical attention.
Less severe allergic reactions include skin rashes that appear later during treatment.
Side effects associated with injecting Colomycin into a vein: Side effects that affect the nervous system are more likely to occur when the dose of Colomycin is too high, in people who have poor kidneys or in those who are also taking muscle relaxants or other medicines with a similar effect on how the nerves work. The most serious of these possible side effects in the nervous system is inability to breathe because of paralysis of the chest muscles.
If the patient experiences any difficulty breathing he/she should seek urgent medical attention.
Other possible side effects include numbness or tingling (especially around the face), dizziness or loss of balance, rapid changes in blood pressure or blood flow (including faintness and flushing), slurred speech, problems with vision, confusion and mental problems (including loss of sense of reality). There can be reactions at the site of the injection, such as irritation.
Kidney problems may also occur. These are especially likely in people who already have poor kidneys, or who are given Colomycin at the same time as other medicines that can cause side effects in the kidneys or who are given a dose that is too high. These problems will normally get better if treatment is stopped or the dose of Colomycin is reduced.
If the patient gets any side effects, he/she should talk to the doctor. This includes any possible side effects not listed.
Side effects associated with inhaling Colomycin (nebulisation): The risk of side effects is usually much less when it is given by inhalation because very little Colomycin usually reaches the bloodstream when it is given this way.
Possible side effects include coughing, a feeling of tightness in the chest due to narrowing of the airways, sore mouth or throat and thrush (Candida) infections of the mouth or throat.
Reporting of side effects: If the patient gets any side effects, he/she should talk to the doctor or pharmacist. This includes any possible side effects not listed.
By reporting side effects the patient can help provide more information on the safety of this medicine.
