A number of Tixylix liquid medicines, including some for toddlers and babies, have been recalled by Novartis.
No adverse effects have been noted, but a "precautionary" recall has been issued, the Medicines and Healthcare products Regulatory Agency (MHRA) said.
Adam Burgess, the MHRA's head of Defective Medicines Reporting Centre, said: "This is a precautionary recall and there is currently no evidence that people have had any problems with these medicines.
"If people have bought Tixylix we ask that they check the batch number on the bottle label next to the expiry date to see if it is one of the batches being recalled. If anyone has an affected batch they should return it to the place of purchase for a refund. If people do have any questions they can contact Novartis on 0800 854 100 or visit tixylix.co.uk."
