Rhodiola and Minoxidil

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

Moderate

ANTIHYPERTENSIVE DRUGS

Why this applies to Minoxidil

Minoxidil falls under ANTIHYPERTENSIVE DRUGS — the group Rhodiola interacts with.

Theoretically, taking rhodiola with antihypertensive drugs might increase the risk of hypotension.
In vitro and animal research shows that rhodiola extract inhibits angiotensin-converting enzyme (ACE) and might lower blood pressure.
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: minoxidil pills are a strong blood pressure lowering medicine, and rhodiola may have a mild blood pressure lowering effect of its own. Put them together and there's a theoretical chance your pressure could dip a little lower than expected. That might show up as feeling lightheaded, dizzy, or faint, especially when you stand up quickly.

I want to be honest about how soft this evidence is. It comes from lab and animal studies, not from people, so the real-world risk is likely small. If you use minoxidil only as a scalp foam for hair (Rogaine), very little gets into your body and this matters even less. Still, since minoxidil is a serious blood pressure drug, please run rhodiola by your pharmacist or doctor first.

  • ProbableInteraction has not been documented in well-controlled studies, however, the interaction has been demonstrated in some small human studies or in controlled animal studies in conjunction with multiple case reports.
  • PossibleInteraction 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.
  • UnlikelyInteraction has been demonstrated in animal or in lab research but has been shown not to occur in humans.
Evidence the quality of the studies behind the rating (graded A–D)
  • AHigh-quality meta-analysis (quantitative systematic review).

From our pharmacist’s overview on the Minoxidil page

“American hellebore heads the concerns for anyone taking minoxidil (Loniten, Rogaine), because even small amounts of its alkaloids lower blood pressure on their own, a dangerous match with one of the most potent pressure-lowering drugs prescribed. It is one of four major-rated entries among the 139 supplements and herbs on record, and t…”

About Rhodiola

What is Rhodiola?

Rhodiola
  • Fatigue and low energy
  • Stress and coping (adaptogen)
  • Mental performance and focus
  • Mild depression
  • Physical and exercise performance

Rhodiola is an herb traditionally used to fight fatigue and help the body cope with stress. Some small studies suggest it may modestly reduce fatigue and improve mood, but the evidence is limited and not strong. It is generally well tolerated for short-term use, but talk to your pharmacist or doctor before trying it, and avoid it during pregnancy and breastfeeding.

About Minoxidil

What Is Minoxidil Used For?

Brand names: Loniten, Rogaine, Minoxidil

Minoxidil tablets are used to treat high blood pressure (hypertension) — specifically in patients who haven't responded well to other blood pressure medications. They are a powerful option reserved for difficult-to-control cases.

Topical minoxidil products — including solutions, sprays, gels, and foams from many brands — are used to regrow hair on the top of the scalp (called the vertex). Products labeled for men and for women may differ; for example, Bosley MD Regular Strength for Women and Dizop Minoxidil Topical Gel are each labeled for their specific intended users.
