Drug & supplement interaction

Chive + Liothyronine

Liothyronine brand name: Cytomel.

No Known Interaction
The bottom line No known interaction

We found no known interaction between Chive and Liothyronine 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. Additionally, although there is no interaction, the two are separately associated with some of the same side effects, which would make a new symptom harder to attribute to one or the other.

Chive and Liothyronine

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 Liothyronine and Chive 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 Chive at all — not against Liothyronine, 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.

No Interaction Found — But Data Suggests Chive and Liothyronine May Share a Side Effect

This is not an interaction. Neither one changes how your body handles the other, and nothing here says they react together. What our sources do show is that each has separately been linked to the effects below — so taking both can make those effects more likely to turn up, and harder to pin on one or the other if they do.

See Every Supplement That Interacts With Liothyronine

This page covers Chive only. If you take other supplements — a multivitamin, a sleep aid, something for joints — the Liothyronine page lists 38 supplements it has a documented interaction with, worst first, each one explained.

The most serious there right now: Activated Charcoal (major), Tiratricol (major), Acetyl-l-carnitine (moderate), Alpha-lipoic Acid (moderate) and Ascophyllum Nodosum (moderate).

By severity: 2 major · 26 moderate · 10 minor.

From our pharmacist’s overview on the Liothyronine page

“Liothyronine (Cytomel) is the active thyroid hormone T3, and it does not tolerate interference well. Of the 38 supplements and herbs on file, 21 act on thyroid function itself, some amplifying the hormone and others blunting it, iodine-rich seaweeds able to swing either way.”

About Chive

What is Chive?

  • Culinary flavoring
  • Digestive support
  • General immune support
  • Antimicrobial
  • Source of vitamins and antioxidants

Chive is a common kitchen herb in the onion and garlic family that is safe and nutritious when eaten as food. There is little human research supporting it as a medicine, so any health benefits beyond basic nutrition are not well proven. Enjoy it in cooking, and talk to your pharmacist or doctor before using concentrated chive supplements.

Allium schoenoprasum · Amaryllidaceae · Leaves (and sometimes flowers and bulbs) · Fresh or dried herb, culinary seasoning, powder, occasional supplement extracts

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

Chive: dosing

There is no established medicinal dose for chive. It is normally used in whatever amount tastes good in food.

From our Chive monograph — the full record covers uses, side effects and every documented interaction.

About Liothyronine

What Is Liothyronine Used For?

Brand name: Cytomel

Liothyronine (available as tablets under the brand names Cytomel, Liomny, and Liothyronine Sodium, and as an injection under Liothyronine Sodium and Triostat) is primarily used to treat hypothyroidism (an underactive thyroid) across all its forms — whether the cause is in the thyroid itself, the pituitary gland, or the hypothalamus, and whether it was present at birth or developed over time.

The oral tablets are also used alongside surgery and radioiodine therapy to suppress TSH (thyroid-stimulating hormone) in people with well-differentiated thyroid cancer, and as a diagnostic agent in thyroid suppression tests. Liothyronine sodium injection is specifically indicated for myxedema coma (a life-threatening form of severe hypothyroidism) and may be used in patients who are allergic to thyroid products derived from pork or beef.

Most-Reported Side Effects for Liothyronine

From FAERS, the FDA’s public side-effect reporting system (0 reports, all brands). Reports are voluntary and are not proof the drug caused the effect.

Fatigue 849 reports
Nausea 585 reports

Taking Chive and Liothyronine Together: Common Questions

Is it safe to take Chive with Liothyronine?
We do not list a known interaction between Chive and Liothyronine. That does not guarantee the combination is risk-free, so confirm with your pharmacist or doctor — especially if you take other medications or have a health condition.
Do Chive and Liothyronine have any of the same side effects?
Yes — our sources link each of them separately to one of the same effects. That is not an interaction: neither changes how your body handles the other. It does mean that if one of those effects turns up, it can be harder to tell which one is behind it. They are listed on this page with the source behind each.
Does Liothyronine interact with any supplements?
Yes. Liothyronine has documented interactions with 38 supplements in our database — Chive is not one of them. The Liothyronine interaction page linked on this page lists every one, ranked by severity.
