Amaranth + Voriconazole
Voriconazole brand name: Vfend.
We found no known interaction between Amaranth and Voriconazole 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.
Amaranth and Voriconazole
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 Voriconazole and Amaranth 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 Amaranth at all — not against Voriconazole, 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.

From our pharmacist’s overview on the Voriconazole page
“Voriconazole (Vfend) is a heavy-hitter antifungal, usually prescribed for dangerous infections like invasive aspergillosis, and its list of 205 interacting supplements includes six rated major, enough that anyone on this drug should read those entries before touching a supplement bottle. Most interactions run through the liver enzymes…”

About Amaranth
What is Amaranth?
- Nutrition and as a gluten-free grain
- High cholesterol
- Diarrhea and digestive upset
- Mouth and throat irritation (gargle)
- Wound and skin care (traditional)
Amaranth is a nutritious plant whose seeds are used as a gluten-free pseudocereal and whose leaves are eaten as a vegetable. It is generally considered safe as a food, but evidence for its medicinal benefits (such as lowering cholesterol) is limited and mostly preliminary. Talk to your pharmacist or doctor before using concentrated supplements.

An interaction check asks whether these two react with each other — it does not ask whether Amaranth is a good idea for someone in your situation. Here is what our Amaranth record says about it on its own.
Amaranth: dosing
There is no established standardized medicinal dose for amaranth. As a food, it is simply prepared and eaten like other grains or leafy vegetables.If you choose a supplement, oil, or capsule, follow the directions on the product label, since the amount of active ingredients can vary widely between products.

About Voriconazole
What Is Voriconazole Used For?
Brand name: Vfend
Voriconazole treats several serious fungal infections. Across all available forms — tablets, oral suspension, and intravenous (IV) injection — it is used for invasive aspergillosis (a dangerous mold infection), candidemia (Candida fungus in the bloodstream) in patients who are not neutropenic (not severely low on white blood cells), other deep-tissue Candida infections, and serious infections caused by Scedosporium apiospermum or Fusarium species in patients who cannot tolerate or have not responded to other antifungal treatments.
Esophageal candidiasis (a Candida infection of the esophagus, the swallowing tube) is also an approved use for most formulations. Note on the oral tablet form (generic voriconazole tablets): that specific tablet formulation is approved for patients aged 12 to 14 years weighing at least 50 kg, and all patients 15 years and older — not for younger or smaller children. The oral suspension and the IV injection are approved for patients 2 years and older for most of these conditions.
Most-Reported Side Effects for Voriconazole
From FAERS, the FDA’s public side-effect reporting system (30,194 reports, all brands). Reports are voluntary and are not proof the drug caused the effect.
