Duckweed and Omadacycline (Oral)

We checked these two against our interaction database. Here is what we found.

No Known Interaction Found

We did not find a documented interaction between Omadacycline (Oral) and Duckweed in our sources. This does not guarantee that the combination is completely free of risk — there is often limited research on supplements and herbal products, especially around drug interactions.

Worth understanding: our licensed dataset holds no drug-interaction record for Duckweed at all — not against Omadacycline (Oral), and not against any other medication we track. This verdict therefore rests on the absence of any recorded data, not on research that looked at this combination and found nothing. We cannot rule an interaction out.

If you decide to take both, the practical routine is simple: add one new thing at a time and note the date you started it. If the combination is going to disagree with you, it usually shows in the first days to a couple of weeks — and a start date turns “I’ve been feeling off” into something a pharmacist can actually work with. Do not stop a prescribed medicine on your own.

Always talk with your pharmacist or doctor before making changes to your medications or supplements, particularly if you take several medications or have an ongoing health condition.

Duckweed safety at a glance

Duckweed overall Use caution Generally considered a food in some cultures, but supplement quality and water contamination are real concerns.
Pregnancy Avoid There is not enough reliable safety information, so avoidance is the safer choice.
Breastfeeding Avoid Safety during breastfeeding has not been established, so avoid it.

Safety guidance is general; always confirm with your pharmacist or doctor for your situation.

What to actually watch for

What Omadacycline (Oral)’s Own FDA Label Lists

This is not an interaction — none of it involves Duckweed. These are the most notable effects listed in the ADVERSE REACTIONS section of Omadacycline (Oral)’s own FDA label, for the medication by itself. Knowing the drug’s own list makes it easier to work out the likely cause if something new turns up while you take both. 4 of them are worth acting on rather than waiting out — marked below.

  • Raised blood pressure Worth acting on
  • Liver problems Worth acting on
  • A higher chance of infection Worth acting on
  • An allergic reaction Worth acting on
  • Diarrhea
  • Vomiting
  • Headache
  • Nausea

From the ADVERSE REACTIONS section of the FDA label for Omadacycline (Oral). Read the label on DailyMed › Duckweed’s licensed record lists no adverse effects our clinical vocabulary could match, so there is no Duckweed side to compare — that is a limit of the record, not a statement that Duckweed has no side effects.

“Omadacycline (Nuzyra) is a tetracycline-class antibiotic, and its list of 41 interacting supplements calls for real care rather than a quick skim. Two entries rate major and deserve to be understood first.”

About Duckweed

What is Duckweed?

  • Plant-based protein source
  • Source of vitamins and minerals
  • Traditional remedy for fever and inflammation
  • Skin conditions and rashes
  • General nutrition and wellness

Duckweed is a tiny floating water plant being studied as a nutrient-dense, plant-based protein and food source. Human evidence for any specific health benefit is very limited, and safety depends heavily on the plant being grown in clean, uncontaminated water. Talk to a pharmacist or doctor before using it as a supplement.

Lemnaceae · Whole plant (fronds) · Powder, capsules, tablets, dried whole plant, protein supplements, traditional decoctions

An interaction check asks whether these two react with each other — it does not ask whether Duckweed is a good idea for someone in your situation. Here is what our Duckweed record says about it on its own.

Duckweed: dosing

There is no official, standardized dose for duckweed supplements. The right amount has not been established in clinical research, and products vary widely in concentration and form.If you choose to use a duckweed product, follow the directions on the label and do not exceed the recommended amount.

About Omadacycline Injection

What Is Omadacycline Injection Used For?

Brand name: Nuzyra

Nuzyra (omadacycline) injection is used in adults to treat two types of serious bacterial infections: community-acquired bacterial pneumonia (CABP) — a lung infection picked up outside of a hospital — and acute bacterial skin and skin structure infections (ABSSSI), which include serious skin infections such as those caused by MRSA (methicillin-resistant Staphylococcus aureus).

Nuzyra works only against bacterial infections. It is not effective against viral illnesses like the flu or common cold. Your doctor will prescribe it only when a bacterial infection is confirmed or strongly suspected, to help prevent the growth of antibiotic-resistant bacteria.
