L-Arginine Drug Interactions
Blood pressure medications, PDE5 inhibitors, and nitrates can interact negatively with L-arginine. Drug interactions with L-arginine may result in dangerously low blood pressure, which could cause dizziness, lightheadedness, or other problems. To avoid these complications, you should not combine L-arginine with any of these medications without your healthcare provider's approval and supervision.
