Use magnesium supplements cautiously. Monitor blood pressure periodically. Rise slowly from sitting or lying positions to reduce fall risk. Generally safe at standard dietary supplement doses with proper monitoring.
Why this interaction occurs
Magnesium's vasodilatory properties may mildly potentiate Irbesartan's blood pressure-lowering effects. The interaction is generally of lower clinical concern at typical supplement doses (200–400 mg/day) but warrants awareness in elderly patients or those already at blood pressure goal on Irbesartan monotherapy.
Evidence
Evidence level: moderate.
