Two batches of saline nasal spray have been recalled from high street chemists due to safety concerns.
Nurses and other health professionals were told that nasal or facial tenderness, discoloured mucus or a fever are among potential symptoms.
Consumers are advised to return 100ml packages of Sterimar Isotonic from either of the affected batches to their dispensing pharmacy or retailer, said the Medicines and Healthcare products Regulatory Agency.
The manufacturer informed the MHRA of a bacterial infection in two batches of the spray, which is commonly used to cleanse the nasal passage. While it should not affect healthy people, there may be a risk posed to those with a weakened immune system, those who suffer from existing sinus or nasal problems, or anyone who recently underwent surgery.
The code number of the affected batches - FE1248b and FE1249 - can be found on the product packaging and on the can’s base.
