Health Canada is warning parents and caregivers about two unauthorized children's syrups for thinning mucus, Robikids and Solmux, seized from Kamshoppe, which advertised the products on Facebook. Both products are labelled to contain carbocisteine, a prescription drug that may pose serious health risks such as nausea, diarrhea, allergic reactions (e.g., anaphylaxis) and gastrointestinal bleeding. Should Health Canada identify other distributors or retailers of these unauthorized health products, it will take action and inform the public as appropriate. Selling unauthorized health products in Canada is illegal. Unauthorized health products have not been approved by Health Canada, which means that they have not been assessed for safety, efficacy and quality and may pose a range of serious health risks. For example, they could contain high-risk ingredients, such as prescription drugs, additives or contaminants that may or may not be listed on the label. These ingredients could interact with other medications and foods. In addition, these products may not actually contain the active ingredients that consumers would expect them to contain to help maintain and improve their health. Prescription drugs should only be used under the advice and supervision of a health care professional because they are used to treat specific conditions and may cause serious side effects.
