antihypertensive
3 interactions related to antihypertensive
amlodipine + calcium
In theory, supplemental calcium could slightly blunt the blood-pressure-lowering effect of calcium channel blockers such as amlodipine, but controlled human data do not show a meaningful effect. Drugs.com flags this as a minor, monitor-only interaction with weak clinical evidence.
dark chocolate + blood pressure medications
Cocoa flavanols in dark chocolate boost nitric-oxide-dependent vasodilation and modestly lower blood pressure. On top of antihypertensive medication the effect is additive and usually helpful, but in sensitive people it can occasionally nudge readings low enough to cause light-headedness.
celery juice + blood pressure medications
Celery contains phthalides (including 3-n-butylphthalide), nitrate, and potassium that relax blood vessels and have a mild blood-pressure-lowering effect demonstrated in a human trial of celery seed extract. Drinking celery juice regularly can add to the effect of antihypertensive drugs such as ACE inhibitors, ARBs, calcium channel blockers, and diuretics, potentially pushing blood pressure lower than intended.
