Collard and Oritavancin Diphosphate

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 Oritavancin Diphosphate and Collard 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.

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.

How we checked

Why No Interaction Is Listed for Oritavancin Diphosphate

Interactions in our licensed database are recorded against drug classes, not just single drug names. Oritavancin Diphosphate is filed under 4 classifications — including cytochrome p450 2c19 (cyp2c19) inhibitors, cytochrome p450 2c9 (cyp2c9) inhibitors, cytochrome p450 3a4 (cyp3a4) inducers. Collard has documented interactions with 1 drug class — the most serious being antidiabetes drugs (moderate) — and none of Oritavancin Diphosphate’s classifications are among them.

Classification data comes from our licensed Natural Medicines dataset. A medication can belong to classes beyond those recorded there, so this describes how the check was run — it is not a safety guarantee.

What to actually watch for

What Oritavancin Diphosphate’s Own FDA Label Lists

This is not an interaction — none of it involves Collard. These are the most notable effects listed in the ADVERSE REACTIONS section of Oritavancin Diphosphate’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. 9 of them are worth acting on rather than waiting out — marked below.

  • Low blood sugar Worth acting on
  • Wheezing Worth acting on
  • A severe skin reaction Worth acting on
  • Anemia Worth acting on
  • A severe allergic reaction Worth acting on
  • Hives Worth acting on
  • Liver problems Worth acting on
  • A higher chance of infection Worth acting on
  • An allergic reaction Worth acting on
  • Itching mentioned in 12.5% of FDA reports for Oritavancin Diphosphate

Showing the 10 most notable of 19 label-listed effects — ranked by how unusual each one is across medicines generally, with serious effects weighted up.

From the ADVERSE REACTIONS section of the FDA label for Oritavancin Diphosphate. Read the label on DailyMed › Where a percentage is shown, it is the share of 297 voluntary FDA FAERS reports for Oritavancin Diphosphate that mention that effect — a reporting proportion, not an incidence rate and not evidence the drug caused it. Collard’s licensed record lists no adverse effects our clinical vocabulary could match, so there is no Collard side to compare — that is a limit of the record, not a statement that Collard has no side effects.

From our pharmacist’s overview on the Oritavancin Diphosphate page

“Oritavancin (Orbactiv, Kimyrsa) is a long-acting antibiotic given as a single IV infusion for serious skin infections, and because one dose stays in the body for days, supplement timing matters more than usual. Even so, none of the 48 ingredients on file rise past moderate, so for most people this list is about knowing what to watch ra…”

About Collard

What is Collard?

  • General nutrition and vitamin source
  • Bone health
  • Heart health support
  • Digestive fiber
  • Antioxidant intake

Collard is a leafy green vegetable in the cabbage family that is rich in vitamins, minerals, and fiber, and is best thought of as a nutritious food rather than a medicine. Eating it as part of a balanced diet is healthy for most people, but there is little high-quality research on collard as a concentrated supplement. If you take blood thinners or have kidney concerns, talk with your pharmacist or doctor because of its vitamin K and oxalate content.

Brassica oleracea var. viridis · Brassicaceae · Leaves · Fresh or cooked leaves, frozen greens; occasionally powders or capsules

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

Collard: dosing

There is no established medicinal dose for collard. As a food, it can be enjoyed in normal serving sizes as part of a varied diet, just like other vegetables.If you choose a collard powder or capsule, there is no standardized dose, so follow the directions on the product label.

About Oritavancin Injection

What Is Oritavancin Injection Used For?

Brand names: Orbactiv, Kimyrsa

Oritavancin injection — available as Orbactiv and Kimyrsa — is used to treat acute bacterial skin and skin structure infections (ABSSSI) in adults. These are serious skin infections caused by susceptible gram-positive bacteria, including Staphylococcus aureus (including MRSA), several Streptococcus species, and vancomycin-susceptible Enterococcus faecalis.

This antibiotic should only be used when a bacterial infection is confirmed or strongly suspected. Using it unnecessarily can contribute to antibiotic resistance.

Most-Reported Side Effects for Oritavancin Diphosphate

From FAERS, the FDA’s public side-effect reporting system (297 reports, all brands). Reports are voluntary and are not proof the drug caused the effect.

Multiple use of single-use product 109 reports
Chills 92 reports
Infusion related reaction 67 reports
Back pain 42 reports
