Dendrobium and Doripenem

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

Moderate

SEIZURE THRESHOLD LOWERING DRUGS

Why this applies to Doripenem

Doripenem falls under SEIZURE THRESHOLD LOWERING DRUGS — the group Dendrobium interacts with.

The dendrobium constituent dendrobine is reported to have convulsant effects. Theoretically, combining dendrobium with pro-convulsant drugs might increase the risk of seizure. Some drugs that lower the seizure threshold include anesthetics (propofol, others), antiarrhythmics (mexiletine), antibiotics (amphotericin, penicillin, cephalosporins, imipenem), antidepressants (bupropion, others), antihistamines (cyproheptadine, others), immunosuppressants (cyclosporine), narcotics (fentanyl, others), stimulants (methylphenidate), theophylline, and others.
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 situation with doripenem (Doribax) and Dendrobium. Doripenem belongs to a family of antibiotics called carbapenems, and one known quirk of this group is that they can slightly lower the seizure threshold, meaning they can make seizures a bit easier to trigger in people who are already prone to them. Dendrobium contains a compound called dendrobine that, at least in lab and animal work, may have convulsant (seizure-promoting) effects.

So in theory, using both together could nudge that seizure risk a little higher. I want to be honest with you though: this is a theoretical concern based on pharmacology, not something proven in people taking these two together. Still, since doripenem is given for serious infections, it's worth telling your doctor or pharmacist about any supplements before you combine them.

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 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 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.
