Tribulus and Clevidipine

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

Moderate

ANTIHYPERTENSIVE DRUGS

Why this applies to Clevidipine

Clevidipine falls under ANTIHYPERTENSIVE DRUGS — the group Tribulus interacts with.

Theoretically, taking tribulus with antihypertensive drugs might increase the risk of hypotension.
Animal research shows that tribulus can lower blood pressure by inhibiting angiotensin-converting enzyme (ACE). Tribulus has also demonstrated hypotensive effects in pre-hypertensive adults.
Severity Moderate 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 gist: Clevidipine (Cleviprex) is a fast-acting IV medication used in a hospital setting to lower blood pressure, often during surgery or a hypertensive emergency. Tribulus, on the other hand, has shown in animal studies and a few human studies that it may modestly lower blood pressure on its own. Stack the two together and the worry is an additive drop, meaning your pressure could fall lower than intended.

In practice, this matters less than it sounds. Clevidipine is given in a closely monitored setting where your team adjusts the dose minute by minute, and the tribulus evidence here is weak, based mostly on lab and animal work. Still, always tell your care team about any supplements you take so they can plan accordingly.

About Tribulus

What is Tribulus?

Tribulus
  • Low libido and sexual function
  • Athletic performance and muscle building
  • Testosterone support
  • Male and female fertility
  • General 'vitality' or wellness

Tribulus is a plant supplement most often marketed to boost libido, testosterone, and athletic performance, but the human evidence behind these claims is weak and inconsistent. It is generally well tolerated by healthy adults in the short term, but it should be avoided during pregnancy and breastfeeding and discussed with your pharmacist or doctor before use.
