The bottom line No known interaction

We found no known interaction between Pink Root and Losartan Potassium in our sources. Absence of a documented interaction is not the same as proven safety, and does not guarantee one does not exist. Do not start, stop, or change a medication or supplement based on this page; confirm with your pharmacist or doctor first.

Pink Root and Losartan Potassium

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 Losartan Potassium and Pink Root 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 Pink Root at all — not against Losartan Potassium, 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.

What Losartan Potassium’s Own FDA Label Lists

This is not an interaction — none of it involves Pink Root. These are the most notable effects listed in the ADVERSE REACTIONS section of Losartan Potassium’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. 10 of them are worth acting on rather than waiting out — marked below.

  • Severe muscle breakdown Worth acting on
  • Muscle weakness Worth acting on
  • High potassium Worth acting on
  • Low sodium Worth acting on
  • Low blood sugar Worth acting on
  • Fainting Worth acting on
  • An irregular heartbeat Worth acting on
  • Shortness of breath Worth acting on mentioned in 5.2% of FDA reports for Losartan Potassium
  • Chest pain Worth acting on
  • Low mood Worth acting on

From the ADVERSE REACTIONS section of the FDA label for Losartan Potassium. Read the label on DailyMed › Where a percentage is shown, it is the share of 89,498 voluntary FDA FAERS reports for Losartan Potassium that mention that effect — a reporting proportion, not an incidence rate and not evidence the drug caused it. Pink Root’s licensed record lists no adverse effects our clinical vocabulary could match, so there is no Pink Root side to compare — that is a limit of the record, not a statement that Pink Root has no side effects.

About Pink Root

What is Pink Root?

  • Intestinal worms (anthelmintic)
  • Digestive complaints
  • Traditional folk remedy

Pink Root (Spigelia marilandica) is a North American plant that was historically used to expel intestinal worms. It contains potentially toxic compounds, has little modern safety or effectiveness data, and is rarely used today. We do not recommend self-treating with it; talk to a healthcare provider about safer, proven options.

Spigelia marilandica · Loganiaceae · Root and rhizome · Dried root, powder, tincture, tea (decoction)

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

Pink Root: dosing

There is no established, standardized safe dose of Pink Root for modern use. Historical doses are not considered reliable or safe by today's standards.Because of its potential toxicity, we do not recommend self-dosing.

About Losartan

What Is Losartan Used For?

Brand name: Cozaar

Losartan tablets — available as branded Cozaar and several generic products — are used to treat high blood pressure (hypertension) in adults and children 6 years and older. Lowering blood pressure reduces the risk of strokes and heart attacks. Losartan tablets are also used to reduce the risk of stroke in people with high blood pressure who also have left ventricular hypertrophy (an enlarged left side of the heart). Note: evidence suggests this stroke-risk benefit may not apply to Black patients.

Losartan tablets are additionally approved to protect the kidneys in people with type 2 diabetes, high blood pressure, and signs of kidney damage (diabetic nephropathy). Arbli, the oral suspension form, shares these same approved uses.

Most-Reported Side Effects for Losartan Potassium

From FAERS, the FDA’s public side-effect reporting system (89,498 reports, all brands). Reports are voluntary and are not proof the drug caused the effect.

Fatigue 6,464 reports
Nausea 5,301 reports
