Amlodipine is a type of calcium channel blocker that relaxes blood vessels to improve blood flow. This helps lower blood pressure and reduce strain on the heart. Studies from sources like the Mayo Clinic and NHS show that while it’s generally well-tolerated, the way it affects blood vessels can lead to certain responses in the body.
Common issues often stem from this vessel relaxation, which sometimes causes fluid shifts or changes in circulation. Research indicates that side effects tend to be more noticeable when starting the medication or at higher doses, but they frequently lessen as your body adjusts.
