Picrorhiza and Lansoprazole, Amoxicillin, Clarithromycin

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 Lansoprazole, Amoxicillin, Clarithromycin and Picrorhiza 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 Lansoprazole, Amoxicillin, Clarithromycin

Interactions in our licensed database are recorded against drug classes, not just single drug names. Lansoprazole, Amoxicillin, Clarithromycin is filed under 14 classifications — including proton pump inhibitors (ppis), macrolide antibiotics, cytochrome p450 1a2 (cyp1a2) inducers. Picrorhiza has documented interactions with 2 drug classes — the most serious being antidiabetes drugs (moderate) and immunosuppressants (moderate) — and none of Lansoprazole, Amoxicillin, Clarithromycin’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 Picrorhiza Itself Has Been Linked To

This is not an interaction — nothing below involves Lansoprazole, Amoxicillin, Clarithromycin. It is the side-effect record for Picrorhiza on its own, from the licensed Natural Medicines monograph. If something new turns up after you add Picrorhiza, this list is the first place to look.

Everything above comes from the Natural Medicines adverse-effect record for Picrorhiza — expand a row for the licensed statement it rests on. We haven’t matched Lansoprazole, Amoxicillin, Clarithromycin to its FDA label in our system yet, so we can’t compare its own side-effect list here — the leaflet that comes with your prescription is the authoritative list for Lansoprazole, Amoxicillin, Clarithromycin.

About Picrorhiza

What is Picrorhiza?

  • Liver support
  • Digestive complaints
  • Asthma and breathing problems
  • Skin conditions
  • Fever
  • Immune support

Picrorhiza (Picrorhiza kurroa) is a bitter Himalayan herb used in Ayurvedic medicine, mainly for liver and digestive complaints. Early lab and small human studies suggest possible liver-protective and anti-inflammatory effects, but high-quality evidence is limited. Talk with your pharmacist or doctor before using it, and avoid it during pregnancy and breastfeeding.

Picrorhiza kurroa · Plantaginaceae · Roots and rhizomes · Capsules, tablets, powder (churna), liquid extracts, and traditional herbal formulas

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

Picrorhiza: dosing

There is no well-established standard dose of Picrorhiza. The amount used can vary widely depending on the form (powder, capsule, or extract) and how concentrated the product is.The safest approach is to follow the dosing directions on the product label and not to exceed them.
