Amlodipine → 3 downstream

Amlodipine

Calcium channel blocker

Torsemide

Loop diuretic

Meclizine

Vestibular sedative

Senna

Laxative

Also feeding this chain: Meclizine → constipation → Senna (possible, 0.34).

Why Domino thinks so

Amlodipine → ankle and leg swelling → Torsemide

Amlodipine started Nov 24, 2025 · Torsemide started Feb 21, 2026

How often it causes this×0.7Peripheral edema is common with Amlodipine.

Timing×1Torsemide started 13 weeks after Amlodipine, inside the usual window for peripheral edema (7 to 120 days).

Other reasons×1.25Torsemide was charted for peripheral edema.

Published evidence×1.2Matches a documented cascade backed by expert consensus (ThinkCascades).

Calcium channel blocker → ankle swelling → diuretic

Evidence: expert consensus

Question for the pharmacist: Could the ankle swelling be from the calcium channel blocker? CCB edema does not respond well to diuretics; a dose change or a different antihypertensive may help instead.
