The NHS has issued a warning to millions of people taking common blood pressure medications, including Amlodipine and Ramipril. Approximately one in three adults in the UK have high blood pressure, often called the 'silent killer' because it can lead to heart attacks and strokes without obvious symptoms.
Ramipril, which widens blood vessels, received around 34.8 million prescriptions last year, while Amlodipine, a calcium channel blocker that relaxes arteries, accounts for over 30 million prescriptions annually. The NHS warns that taking these medications together, or with other blood pressure drugs like lisinopril, can lower blood pressure too much, causing dizziness or fainting.
If you experience symptoms of low blood pressure—such as dizziness, light-headedness, blurred vision, fainting, nausea, or fatigue—you should see your doctor, as your dose may need adjustment. The NHS also advises caution with herbal remedies like St John's wort, which can affect how Amlodipine works.
Patients are urged to tell their doctor about all medicines they take, including herbal supplements and vitamins, to avoid dangerous interactions. Regular blood pressure checks are recommended for those on these medications.
