The bottom line No known interaction

We found no known interaction between American Ivy and Doxycycline Hyclate 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 label for Doxycycline Hyclate states a food rule worth keeping to.

American Ivy and Doxycycline Hyclate

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 Doxycycline Hyclate and American Ivy 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.

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.

American Ivy safety at a glance

American Ivy overall Use caution Little safety data exists, and the berries are toxic, so use it cautiously and avoid eating any part of the plant.
Pregnancy Avoid There is not enough safety information, so it is best to avoid use during pregnancy.
Breastfeeding Avoid Safety while breastfeeding is unknown, so avoiding it is the safer choice.

Safety guidance is general; always confirm with your pharmacist or doctor for your situation.

How we checked

Why No Interaction Is Listed for Doxycycline Hyclate

Interactions in our licensed database are recorded against drug classes, not just single drug names. Doxycycline Hyclate is filed under 9 classifications — including tetracycline antibiotics, antibiotic drugs, p-glycoprotein substrates. American Ivy has documented interactions with 1 drug class — the most serious being thiazide diuretics (moderate) — and none of Doxycycline Hyclate’s classifications are among them.

Classification data comes from our licensed Natural Medicines dataset. A medication can belong to classes beyond those recorded there, so this describes how the check was run — it is not a safety guarantee.

What Doxycycline Hyclate’s Own FDA Label Lists

This is not an interaction — none of it involves American Ivy. These are the most notable effects listed in the ADVERSE REACTIONS section of Doxycycline Hyclate’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.

  • Thoughts of self-harm Worth acting on
  • Trouble swallowing Worth acting on
  • Hallucinations Worth acting on
  • Low mood Worth acting on
  • A low platelet count Worth acting on
  • Kidney problems Worth acting on
  • Anemia Worth acting on
  • Raised blood pressure Worth acting on
  • A severe allergic reaction Worth acting on
  • Hives Worth acting on

From the ADVERSE REACTIONS section of the FDA label for Doxycycline Hyclate. Read the label on DailyMed › American Ivy’s licensed record lists no adverse effects our clinical vocabulary could match, so there is no American Ivy side to compare — that is a limit of the record, not a statement that American Ivy has no side effects.

How to take them

Some Doxycycline Hyclate Products Have a Food Rule — American Ivy Should Not Break It

At least one FDA label for a product containing Doxycycline Hyclate says to take it on an empty stomach. Most supplements — American Ivy included — are taken with a meal, so the easy mistake is swallowing both together at breakfast. Where that rule applies, keep Doxycycline Hyclate on its own and move American Ivy to a meal later in the day.

This may not be true of your version. Food instructions belong to the product, not the ingredient: two Doxycycline Hyclate products can carry different directions, and extended-release forms often differ from immediate-release ones. The label we read is quoted below — check the directions on your own box or bottle, or ask your pharmacist, for how to take the exact product you were given.

2 DOSAGE AND ADMINISTRATION Take one Doxycycline capsule (40 mg) once daily in the morning on an empty stomach, preferably at least one hour prior to or two hours after meals.

From the Dosage and Administration section of the FDA label we read for Doxycycline Hyclate — where that label names a specific product, the instruction is that product's. Read the label on DailyMed ›

A food rule is not an interaction — it is about how much of the medicine you absorb. The directions that came with your own product, and your pharmacist, outrank anything on this page.

Where does our data come from?
  • Source: the Natural Medicines (TRC Healthcare) clinical database — the evidence-graded professional reference for herb & supplement interactions. American Ivy is not yet covered by that licensed database, so its write-up cites publicly available medical sources directly (see the references below).

About American Ivy

What is American Ivy?

American Ivy
  • Digestive upset
  • To stimulate sweating
  • Traditional tonic use
  • Skin and swelling complaints (topical folk use)

American Ivy (Virginia creeper) is mainly an ornamental climbing vine with a long history of folk use for digestion and sweating, but there is very little human evidence to support any health benefit. Its berries contain oxalic acid and are considered poisonous, and the plant can irritate the skin. Because safety data is limited, talk with your pharmacist or doctor before using it.

Parthenocissus quinquefolia · Vitaceae · Bark, leaves, and stems (berries are considered poisonous) · Dried bark, tinctures, teas; rarely sold as a standardized supplement

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

American Ivy: dosing

There is no established safe or effective dose for American Ivy. It is not a standardized supplement, so the strength of any product can vary a lot.If you choose to use a product that contains it, follow the directions on the label and do not exceed them. Never make a home preparation from the raw plant or its berries.

About Doxycycline

What Is Doxycycline Used For?

Brand names: Acticlate, Acticlate Cap, Lymepak

Doxycycline belongs to the tetracycline family of antibiotics. It's prescribed for many types of bacterial infections, including respiratory tract infections, sexually transmitted infections (STIs), tick-borne illnesses like Rocky Mountain spotted fever, and eye infections. It's also used to help prevent malaria and, in some cases, as a helper treatment for severe acne.

In situations where penicillin-type antibiotics can't be used — due to allergy, for example — doxycycline can step in as an alternative. It should only be used for infections that are proven or strongly suspected to be caused by bacteria.

Is it safe to take American Ivy with Doxycycline Hyclate?

Should I take American Ivy and Doxycycline Hyclate at the same time of day?

Interactions in our licensed database are recorded against drug classes. Doxycycline Hyclate is filed under 9 classifications, and American Ivy has documented interactions with 1 drug class — none of Doxycycline Hyclate's classifications are among them. A medication can belong to classes beyond those recorded in our dataset, so this describes how the check was run rather than guaranteeing safety.
