Dendrobium and Amiloride

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

Minor

ANTIHYPERTENSIVE DRUGS

Why this applies to Amiloride

Amiloride falls under ANTIHYPERTENSIVE DRUGS — the group Dendrobium interacts with.

The dendrobium constituent dendrobine is reported to have hypotensive effects. Theoretically, combining dendrobium with antihypertensive drugs might increase the risk of hypotension; use with caution.
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 simple version: Amiloride is a 'potassium-sparing' water pill that helps lower blood pressure. Dendrobium contains a compound called dendrobine that may have a mild blood-pressure-lowering effect of its own. So if you take both, the worry is that they could add together and drop your pressure a little too much.

If that happened, you might feel dizzy, lightheaded, tired, or wobbly when you stand up. I want to be honest though: this is a theoretical concern based on how dendrobine behaves in lab settings, not from real patient reports, and it's rated as minor. Still, since everyone responds differently, check with your pharmacist or doctor before adding Dendrobium, and let them know if you notice new dizziness.

About Dendrobium

What is Dendrobium?

  • Dry mouth and thirst
  • Supporting digestion
  • General tonic/vitality
  • Eye and skin health
  • Recovery after illness

Dendrobium is a group of orchids long used in traditional Chinese medicine, often to moisten the body and as a general tonic. Human evidence for its modern health claims is very limited, so it should be viewed as a traditional remedy rather than a proven treatment. Talk to your pharmacist or doctor before using it, and avoid it during pregnancy and breastfeeding because safety isn't known.

About Amiloride

What Is Amiloride Used For?

Brand names: Midamor, Amilamont

Amiloride is used together with other diuretics (water pills) to treat congestive heart failure and high blood pressure (hypertension). It is added to a thiazide or similar diuretic to either restore low potassium levels or prevent them from dropping dangerously in the first place.

It is especially useful for people who are at particular risk if their potassium falls too low — for example, those taking digoxin or those with significant heart rhythm problems. Amiloride is rarely used on its own, as its diuretic and blood-pressure-lowering effects are weak compared with other diuretics.
