Interaction report

American Adder's Tongue and Mycophenolate Mofetil

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 Mycophenolate Mofetil and American Adder's Tongue 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 American Adder's Tongue at all — not against Mycophenolate Mofetil, 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.

About American Adder's Tongue

What is American Adder's Tongue?

Skin ulcers and wounds
Swollen glands
Minor skin irritation
Folk remedy for nausea (as an emetic)

American Adder's Tongue (Erythronium americanum) is a woodland lily used in traditional folk medicine, mainly as a crushed-leaf poultice for skin ulcers and wounds. There is very little modern scientific evidence to support any of its uses, and safety information is limited, so it should be used cautiously and avoided in pregnancy and breastfeeding.

Erythronium americanum · Liliaceae · Leaves and tubers (corms) · Crushed fresh leaves (poultice), juice, tea, tincture

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

About Mycophenolate Injection

What Is Mycophenolate Injection Used For?

Brand name: CellCept

Mycophenolate mofetil is used to prevent the body from rejecting a transplanted kidney, heart, or liver. It is always used alongside other immunosuppressant medicines, not on its own.

CellCept Intravenous (the injectable form) is specifically for transplant patients who are temporarily unable to take oral medication. It is given by IV infusion and is meant to bridge the gap until the patient can switch to an oral form of CellCept.
