Ranitidine is not currently available in the UK or globally. It has been discontinued as a precaution because it may contain a small amount of an impurity that has been linked to an increased risk of cancer in animals. It's not yet known whether it will be available again in future.
Ranitidine is a medicine that reduces the amount of acid your stomach makes. It was used for indigestion, heartburn and acid reflux, gastro-oesophageal reflux disease (GORD – this is when you keep getting acid reflux), and to prevent and treat stomach ulcers.
Talk to your doctor if you have indigestion, or heartburn and acid reflux. There are similar medicines they can prescribe for you if you need treatment.
If you've taken ranitidine in the past, any risk is likely to be very low, but if you have any concerns, speak to a pharmacist or doctor.
