European Mistletoe and Indapamide

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

Moderate

ANTIHYPERTENSIVE DRUGS

Why this applies to Indapamide

Indapamide falls under ANTIHYPERTENSIVE DRUGS — the group European Mistletoe interacts with.

Theoretically, European mistletoe might increase the risk of hypotension when taken with antihypertensive drugs.
Animal research suggests that European mistletoe extracts have hypotensive effects.
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

Indapamide is a water pill that lowers blood pressure by helping your body release extra salt and fluid. European mistletoe, based mostly on animal studies, may also lower blood pressure on its own. So the worry here is simple: pairing the two could push your blood pressure down a little too far.

If that happens, you might feel dizzy, lightheaded, tired, or faint, especially when standing up quickly. Keep in mind this is a theoretical concern drawn from lab and animal data, not strong human proof, so it's not a reason to panic. Still, mistletoe should only be used under medical supervision. Before combining them, please check with your pharmacist or doctor, and tell them if you notice unusual dizziness.

About European Mistletoe

What is European Mistletoe?

European Mistletoe
  • Cancer supportive care
  • Immune support
  • High blood pressure
  • Anxiety and stress
  • Inflammation

European mistletoe is a parasitic plant most studied as an injectable extract used alongside conventional cancer care in some European countries, mainly to improve quality of life rather than to cure cancer. The plant is toxic if eaten, and oral or self-treatment can be dangerous, so it should only be used under medical supervision. Talk to your pharmacist or doctor before using any mistletoe product.

About Indapamide

What Is Indapamide Used For?

Brand names: Lozol, Lozide

Indapamide tablets are used to treat high blood pressure (hypertension), either on their own or together with other blood pressure medications. Lowering blood pressure helps reduce the risk of related complications.

Indapamide tablets are also used to treat salt and fluid retention (edema) associated with congestive heart failure. In certain cases, indapamide may also be appropriate during pregnancy when swelling is caused by a medical condition rather than normal pregnancy changes — but routine use in otherwise healthy pregnant women is not recommended.
