Nicotinamide Riboside and Sodium Nitroprusside

Here is the interaction we found between these two, with the evidence behind it.

Minor

ANTIHYPERTENSIVE DRUGS

Why this applies to Sodium Nitroprusside

Sodium Nitroprusside falls under ANTIHYPERTENSIVE DRUGS — the group Nicotinamide Riboside interacts with.

Theoretically, nicotinamide riboside may have additive effects with antihypertensive drugs, potentially increasing the risk for hypotension.
One small clinical study suggests that nicotinamide riboside can modestly reduce blood pressure in hypertensive patients. However, other clinical research did not find a reduction in blood pressure when compared with control.
Severity Minor Likelihood Possible Evidence D

Interaction has been documented in animal or in lab research, or the interaction has been documented in humans but is limited to case reports or conflicting clinical research exists.

Dr. Brian Staiger, PharmD, BCPS
Dr. Brian Staiger explains PharmD, Clinical Pharmacist

Here's the practical side of this one. Sodium nitroprusside is a powerful blood pressure lowering drug given only through an IV in a hospital, usually for blood pressure emergencies. Nurses and doctors are watching your numbers very closely and adjusting the drip minute by minute. The theory here is that nicotinamide riboside (a form of vitamin B3) might nudge blood pressure down a little on its own, which could in theory add to the drug's effect and lead to too much of a drop, meaning dizziness, a fast heartbeat, or fainting.

Honestly, this concern is mostly theoretical, and the human evidence for NR lowering blood pressure is mixed and weak. Since nitroprusside is hospital-controlled, the team can simply adjust the dose. Still, mention any supplements you take to your care team so they have the full picture.

From our pharmacist’s overview on the Sodium Nitroprusside page

“Sodium nitroprusside (Nipride RTU) is given by IV in hospitals to bring dangerously high blood pressure down within minutes, so anything that nudges pressure in either direction earns real vigilance here. All but two of the 121 supplements and herbs on this page interact through blood pressure itself, and the three major-rated entries…”

About Nicotinamide Riboside

What is Nicotinamide Riboside?

  • Healthy aging
  • Boosting cellular energy
  • Supporting metabolism
  • General wellness
  • Athletic recovery

Nicotinamide riboside (NR) is a form of vitamin B3 that the body converts into NAD+, a molecule involved in cellular energy and repair. Early human studies show it can reliably raise NAD+ levels and appears generally well tolerated, but solid evidence that it improves aging, energy, or specific health conditions is still limited. Talk with your pharmacist or doctor before starting it.
