Health Canada is advising Canadians that EMD Serono, a Division of EMD Inc. Canada, is recalling one lot of Cetrotide 0.25mg because some vials may have missing stoppers, which could make the product unsterile. Cetrotide is used in fertility treatment to help women get pregnant by stopping the body from releasing an egg from the ovary (ovulation) early so that it can be released at the best time for pregnancy to occur. An unsterile product could introduce microorganisms when injected under the patient’s skin. This may result in a local infection, such as an abscess, or an infection of the skin and deeper underlying tissues (cellulitis). Some infections can be serious if they spread to the blood, bones, heart or other areas of the body. In addition, some of the contents of the vial may have spilled out because of the missing stopper, so the patient may not receive the proper dose and the drug would not be as effective. Health Canada will monitor the company’s recall and inform Canadians if new safety information becomes available.
