Anyone else get 'balloon ankles' by 5 PM after bumping Amlodipine from 5 mg to 10 mg? Did dropping back to 5 mg + adding an ARB/ACEi fix it?
On Amlodipine 5 mg I had zero side effects, so when my systolic BP was still hovering around 136 mmHg, my doctor doubled my Amlodipine to 10 mg. Within two weeks my socks were leaving deep indentations around my ankles every evening! My doctor explained that dihydropyridine calcium channel blockers dilate the little arteries entering the capillary bed without dilating the veins exiting it, creating hydrostatic pressure that pushes fluid into the ankles. Instead of giving me a water pill (which doesn't fix capillary pressure), she dropped my Amlodipine back to 5 mg and added Losartan 50 mg—because ARBs and ACE inhibitors dilate the venous return side! Within 10 days my ankle swelling disappeared AND my blood pressure dropped to 118/72. What combination worked best for your blood pressure without ankle edema?
In clinical hypertension trials (ACCOMPLISH), Amlodipine peripheral edema is strongly dose-dependent (~2%–3% at 5 mg vs. 10%–15% at 10 mg). Combining Amlodipine 5 mg with an ACE inhibitor or ARB causes post-capillary venular dilation, reducing ankle edema by >50% while providing superior 24-hour BP reduction.
