UK doctors are being told to stop prescribing four types of a heartburn medication called Zantac or ranitidine as a "precautionary measure".
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.
