Zantac heartburn medicine recall in UK
UK doctors were instructed to stop prescribing four types of heartburn medication called Zantac, or ranitidine, as a "precautionary measure", BBC reports.
It follows concern in several countries that products may contain an impurity that has been linked to cancer.
The four being recalled are Zantac 150mg/10ml Syrup, Zantac 50mg/2ml Injection, Zantac 150mg Tablets and Zantac 300mg Tablets.
But patients should keep taking their prescribed medicine, officials advise.
The Medicines and Healthcare products Regulatory Agency (MHRA) says the health risk of discontinuing the medicine is higher than the potential risk presented by the contaminant N-nitrosodimethylamine (NDMA).
Anyone who is concerned about taking their medication should speak to their doctor or pharmacist.
NDMA is classified as a probable human carcinogen (a substance that could cause cancer) on the basis of animal studies. It is present in some foods and in water supplies but is not expected to cause harm when ingested in very low levels.
The MHRA has asked manufacturers to quarantine all products which may contain the active pharmaceutical ingredient (API) that is potentially affected by this issue.
The four in the recall are made by GlaxoSmithKline (GSK).
