Amlodipine-Related Dizziness and Hypotension

Incidence and Clinical Evidence

• The incidence of dizziness with amlodipine is consistently reported across multiple clinical contexts, according to the American Heart Association and American College of Cardiology 1, 2

Mechanism and Clinical Characteristics

• Dizziness from amlodipine is primarily related to its vasodilatory effects, which can cause systemic hypotension, as reported by the American College of Cardiology and the European Society of Cardiology 1, 3
• Amlodipine has high selectivity for vascular L-type calcium channels, producing marked peripheral vasodilation, according to the European Society of Cardiology 3

Adverse Effects

• The adverse effect profile of amlodipine includes hypotension, as reported by the European Society of Cardiology 4
• Amlodipine can cause flushing, headache, and peripheral edema, according to the European Society of Cardiology and the American Heart Association 3, 5

Special Populations at Higher Risk

• Older adults are at increased risk for dizziness and falls with amlodipine, as noted by the European Society of Cardiology 6, 7
• The European Society of Cardiology guidelines specifically note that calcium channel blockers can increase the risk of hypotension, falls, and dizziness in older adults 4, 6, 7

Clinical Management Considerations

• The European Society of Cardiology recommends starting with lower doses in patients at risk for hypotension-related dizziness, and monitoring blood pressure (both standing and recumbent) is recommended, particularly in elderly patients 7, 8, 5
• Symptomatic hypotension and dizziness often improve with time, though dose reduction of other concurrent hypotensive agents may be necessary, as reported by the European Society of Cardiology 4
