Interaction report

Picrorhiza and Phenindamine Tartrate

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 Phenindamine Tartrate 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 Phenindamine Tartrate

Interactions in our licensed database are recorded against drug classes, not just single drug names. Phenindamine Tartrate is filed under 3 classifications — photosensitizing drugs, seizure threshold lowering drugs, oral drugs. Picrorhiza has documented interactions with 2 drug classes — the most serious being antidiabetes drugs (moderate) and immunosuppressants (moderate) — and none of Phenindamine Tartrate’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 Phenindamine Tartrate. 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 Phenindamine Tartrate 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 Phenindamine Tartrate.

See Every Supplement That Interacts With Phenindamine Tartrate

The most serious there right now: Activated Charcoal (major), Alfalfa (moderate), Angelica Archangelica (moderate), Arrach (moderate) and Bergamot (moderate).

By severity: 1 major · 32 moderate · 10 minor.

From our pharmacist’s overview on the Phenindamine Tartrate page

“Phenindamine tartrate (Nolahist) is an antihistamine for hay fever and cold symptoms, and this is one supplement list worth studying rather than skimming. The single major-rated interaction among the 43 on file is activated charcoal, which can soak up the medication in your gut and weaken its effect, so keep the two well apart.”

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.

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.
