The bottom line No known interaction

We found no known interaction between Plant Sterols and Terconazole 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.

Plant Sterols and Terconazole

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 Terconazole and Plant Sterols 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 Plant Sterols at all — not against Terconazole, 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 to actually watch for

What Plant Sterols Itself Has Been Linked To

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

  • Acne Additional detail

    “Peripheral precocious puberty has been described in a 20-month-old boy who ingested about 15 grams daily of a chicken essence product containing the plant sterol avenasterol, also known as clerosterol or chondrillasterol. Signs and symptoms included elevated estradiol and testosterone levels, acne, hairiness, increased penis size, hoarse voice, and increased growth rate.”

  • Stomach upset / Diarrhea Additional detail

    “Abdominal discomfort has occurred in one child in a clinical trial of oral plant sterols. Because plant sterols decrease cholesterol absorption in the gut, there is concern that they might produce some gastrointestinal symptoms like diarrhea and excess amounts of fat in the stool (steatorrhea), although these adverse effects have not been reported in clinical research.”

  • A skin rash Additional detail

    “Acute dermatitis has been reported in a case report of a 51-year-old female who used a pharmacy-brand plant sterol supplement to lower cholesterol levels. The rash was widespread with lesions on the hands and feet and a red and swollen face. The patient was treated orally with prednisolone and topically with emollients for 2 weeks.”

Everything above comes from the Natural Medicines adverse-effect record for Plant Sterols — expand a row for the licensed statement it rests on. We read the ADVERSE REACTIONS section of Terconazole’s FDA label too, and the two lists don’t meaningfully overlap — which is why no Terconazole column appears here.

See Every Supplement That Interacts With Terconazole

This page covers Plant Sterols only. If you take other supplements — a multivitamin, a sleep aid, something for joints — the Terconazole page lists 20 supplements it has a documented interaction with, worst first, each one explained.

The most serious there right now: Activated Charcoal (major), Coffee Charcoal (moderate), European Mandrake (moderate), Glucomannan (moderate) and Guar Gum (moderate).

By severity: 1 major · 7 moderate · 12 minor.

From our pharmacist’s overview on the Terconazole page

“Terconazole (Terazole) is a vaginal antifungal for yeast infections, and its supplement list earns genuine caution because of one standout: activated charcoal, the only major-rated interaction among the 20 on file. Charcoal binds many medicines and can lower their levels even when a drug is not taken by mouth, which makes it the entry…”

About Plant Sterols

What is Plant Sterols?

  • High cholesterol
  • Heart health support
  • Lowering LDL cholesterol

Plant sterols (and their close relatives, plant stanols) are natural compounds found in plants that can modestly lower LDL ('bad') cholesterol when taken regularly in adequate amounts, usually through fortified foods or supplements. They are widely considered a useful add-on to a heart-healthy diet, but they are not a replacement for prescribed cholesterol medicine. Talk with your pharmacist or doctor before starting them, especially if you take cholesterol drugs.

Sterols extracted from plant oils, nuts, seeds, grains, and legumes · Capsules, softgels, fortified margarine/spreads, fortified yogurt and milk, powders

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

Plant Sterols: dosing

There is no single official dose for everyone, but cholesterol-lowering benefits are generally seen only when enough is taken consistently each day, usually spread across meals. Taking them with food is often recommended, since they work by affecting how cholesterol is absorbed during digestion.The best approach is to follow the directions on your specific product label, since fortified foods and supplements vary in strength.

About Terconazole

What Is Terconazole Used For?

Brand name: Terazole

Terconazole vaginal cream and vaginal suppositories are both indicated for the local treatment of vulvovaginal candidiasis — commonly known as a vaginal yeast infection caused by Candida species. Because these products only work against Candida, a healthcare provider should confirm the diagnosis before or during treatment.

Before starting a second course of treatment with terconazole vaginal suppositories, the diagnosis should be re-confirmed by lab tests and other possible causes of symptoms should be ruled out.
