A blood pressure medication has been recalled from suppliers due to possible “microbial contamination”.

Amlodipine is a calcium channel blocker used to treat high blood pressure and can cut the risk of heart disease, heart attacks and strokes.

It works by relaxing and widening blood vessels, making it easier for the heart to pump blood around the body.

A notice issued by the Medicines and Healthcare Products Regulatory Agency said there were no reports of patients being harmed or becoming ill from taking the medicine.

However, manufacturer Bristol Laboratories Limited has asked healthcare professionals to stop supplying certain batches of Amlodipine Bristol Lab 2.5 mg Tablets.

Patients were advised to continue taking their medicines as prescribed and seek medical attention if they experience any adverse effects or have questions.

The recall applies to specific batches of tablets issued in 2023 which have an expiry date of July 2025.

More than 14 million people in the UK are thought to suffer from high blood pressure, increasing their risk of strokes and deadly heart problems.

Amlodipine is usually taken once daily at the same time. Side effects can include dizziness, headaches, flushing and tiredness.

The MHRA notice said: “No further action is required by patients as this is a Pharmacy and Wholesaler level recall.

“There have been no reports of patients being harmed or becoming ill from taking this medicine. 

“Patients should continue to take medicines from this batch as prescribed by your healthcare professional.”
