Peony and Lamivudine, Raltegravir

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 Lamivudine, Raltegravir and Peony 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 Lamivudine, Raltegravir

Interactions in our licensed database are recorded against drug classes, not just single drug names. Lamivudine, Raltegravir is filed under 5 classifications — including integrase inhibitors, nucleoside reverse transcriptase inhibitors (nrtis), glucuronidated drugs. Peony has documented interactions with 7 drug classes — the most serious being anticoagulant/antiplatelet drugs (moderate), clozapine (clozaril) (moderate) and contraceptive drugs (moderate) — and none of Lamivudine, Raltegravir’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 Peony Itself Has Been Linked To

This is not an interaction — nothing below involves Lamivudine, Raltegravir. It is the side-effect record for Peony on its own, from the licensed Natural Medicines monograph. If something new turns up after you add Peony, this list is the first place to look. One entry is worth acting on rather than waiting out — marked below.

  • Bleeding or bruising Worth acting on Additional detail

    “Orally, there is one case report of easy gum bleeding, epistaxis, and skin bruising with an international normalized ratio (INR) above 6 in a 61-year-old male who was previously stable on warfarin therapy. This patient had switched from one brand of quilinggao, a popular Chinese herbal product, to another brand 5 days prior. This product contained Fritillaria spp.”

  • Bloating or gas / Reduced appetite / Stomach upset / Diarrhea / Nausea Additional detail

    “Orally, peony and total glucosides of peony (TGP) have been reported to cause gastrointestinal discomfort, including abdominal distension, anorexia, diarrhea, and nausea, in some patients.

From our pharmacist’s overview on the Lamivudine, Raltegravir page

“With Dutrebis (lamivudine and raltegravir), the stakes are keeping HIV fully suppressed, so I treat these 34 interactions as ones to get ahead of, not shrug off. The single major-rated entry is activated charcoal, which soaks up medicine in the gut and can strip out enough of the dose to matter.”

About Peony

What is Peony?

Peony
  • Menstrual cramps and irregular periods
  • Muscle cramps and spasms
  • Anxiety and stress
  • Inflammation and pain
  • Polycystic ovary syndrome (PCOS)

Peony root is a traditional Chinese medicine herb often used for menstrual problems, cramps, and inflammation, frequently as part of combination formulas. Human evidence for most uses is limited or preliminary, so it should not replace proven treatments. Talk to your pharmacist or doctor before using it, especially if you are pregnant, breastfeeding, or taking other medicines.

Paeonia lactiflora · Paeoniaceae · Root (and sometimes the root bark, flower, and seeds) · Dried root, powders, capsules, tinctures, teas, and combination herbal formulas

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

Peony: dosing

There is no well-established standardized dose for peony. The amount used varies depending on the form (dried root, powder, capsule, tincture, or tea) and whether it is used alone or in a combination formula.The safest approach is to follow the directions on the product label and to choose products from reputable manufacturers.
