Star Of Bethlehem and Doripenem

These two interact in 2 distinct ways. Each one is explained separately below.

Why Are There 2 Interactions?

Star Of Bethlehem interacts with whole categories of medication. Doripenem falls into 2 of those categories, so it can interact with Star Of Bethlehem in 2 different ways. We’ve listed each one below — your overall risk is driven by the most serious of them (Moderate).

Moderate

MACROLIDE ANTIBIOTICS

1 of 2

Why this applies to Doripenem

Doripenem falls under MACROLIDE ANTIBIOTICS — the group Star Of Bethlehem interacts with.

Theoretically, taking macrolide antibiotics with star of Bethlehem might increase the risk of cardiac glycoside toxicity.
Star of Bethlehem contains cardiac glycosides. Macrolide antibiotics appear to increase the gastrointestinal absorption of oral digoxin. Theoretically, concomitant use of macrolide antibiotics might increase the absorption of the cardiac glycosides found in star of Bethlehem and increase the risk of adverse 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 explains PharmD, Clinical Pharmacist

Here's the thing to understand about this pairing. Star of Bethlehem naturally contains cardiac glycosides, which are heart-active compounds similar to digoxin. The concern on file is that some antibiotics can boost how much of those glycosides your gut absorbs, which could, in theory, push you toward heart-rhythm problems, nausea, or feeling unusually tired or dizzy.

A couple of honest points, though. This warning was built around macrolide antibiotics (like erythromycin), and Doripenem (Doribax) is actually a carbapenem, a different class, so it may not behave the same way. On top of that, this is a purely theoretical interaction, not something proven in people. And most flower-essence products are so diluted they contain little to no actual plant chemical. Still, since Doripenem treats serious infections, please run any star of Bethlehem product by your pharmacist or doctor first.

TETRACYCLINE ANTIBIOTICS

2 of 2

Doripenem also falls under TETRACYCLINE ANTIBIOTICS.

Theoretically, taking tetracycline antibiotics with star of Bethlehem might increase the risk of cardiac glycoside toxicity.
Star of Bethlehem contains cardiac glycosides similar to digitalis. Tetracycline antibiotics appear to increase the gastrointestinal absorption of oral digoxin. Theoretically, concomitant use of tetracycline antibiotics might increase the absorption of the cardiac glycosides found in star of Bethlehem and increase the risk of adverse effects.
Severity Moderate Likelihood Possible Evidence D

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

Here's the gist for doripenem (Doribax). Star of Bethlehem naturally contains heart-acting compounds called cardiac glycosides, similar to digitalis. The concern on file is that certain antibiotics may boost how much of these glycosides your gut absorbs, which could raise the odds of glycoside-type side effects like an irregular or slow heartbeat, nausea, or feeling dizzy. Doripenem itself is not a prodrug, so it stays an active antibiotic either way.

Honestly, this is a theoretical flag based on how tetracyclines behave, and doripenem is a carbapenem given by IV, not a tetracycline taken by mouth, so the overlap is shaky. Most flower-essence products are also so diluted they contain almost no plant chemicals. Still, please mention any supplement to your pharmacist or doctor.

From our pharmacist’s overview on the Doripenem page

“Two entries here matter more than all the others, and I would read them first. Doripenem (Doribax) is an intravenous antibiotic reserved for serious bacterial infections, which means anything that weakens treatment or piles on risk deserves genuine caution.”

About Star Of Bethlehem

What is Star Of Bethlehem?

  • Emotional shock and trauma
  • Grief and bereavement
  • Stress relief
  • Calming and comfort

Star of Bethlehem is a small flowering plant best known as one of the ingredients in Bach flower remedies, where it is used for emotional shock and grief. There is no solid scientific evidence that it treats any medical condition, and the raw plant and bulb are considered toxic, so it should not be eaten. If you choose to use a flower-essence product, treat it as a complement to—not a replacement for—proper medical care.

About Doripenem Injection

What Is Doripenem Injection Used For?

Brand name: Doribax

  • Doripenem injection is used to treat serious infections of the urinary tract, kidney, and abdomen that are caused by bacteria. Doripenem injection is not approved by the Food and Drug Administration (FDA) to treat pneumonia that developed in people who were on a ventilator in a hospital. Doripenem injection is in a class of medications called carbapenem antibiotics. It works by killing bacteria.

  • Antibiotics such as doripenem injection will not work for colds, flu, or other viral infections. Taking antibiotics when they are not needed increases your risk of getting an infection later that resists antibiotic treatment.
