Drug & supplement interaction

Uzara + Imiquimod

Imiquimod brand names: Aldara, Zyclara, Vyloma.

No Known Interaction
Medically reviewed by · Updated July 2026 · Pair last verified Sep 20, 2026
The bottom line No known interaction

We found no known interaction between Uzara and Imiquimod 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.

Uzara and Imiquimod

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 Imiquimod and Uzara 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.

How we checked

Why No Interaction Is Listed for Imiquimod

Interactions in our licensed database are recorded against drug classes, not just single drug names. Imiquimod is filed under a single classification — topical drugs. Uzara has documented interactions with 6 drug classes — the most serious being digoxin (lanoxin) (major), diuretic drugs (moderate) and macrolide antibiotics (moderate) — and none of Imiquimod’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.

No Interaction Found — But Data Suggests Uzara and Imiquimod 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.

    Uzara

    “Orally, uzara can cause cardiotoxic effects, especially in patients with pre-existing cardiovascular disease. In one case report, a 68-year-old female with diabetes and hypertension was admitted to the emergency room with reduced left-ventricular function, pulmonary edema, and arrhythmia.”

    Imiquimod

    Listed in the ADVERSE REACTIONS section of the FDA label for Imiquimod. Read the label on DailyMed ›

Reported for Uzara but not commonly for Imiquimod: raised blood pressure and an irregular heartbeat.

Effects for Imiquimod come from the ADVERSE REACTIONS section of its FDA label; effects for Uzara come from the Natural Medicines adverse-effect record, quoted above. Wording is matched across sources by our own clinical vocabulary, so treat this as a prompt to pay attention, not a diagnosis.

From our pharmacist’s overview on the Imiquimod page

“Imiquimod (Aldara, Zyclara, Vyloma) is a cream for warts, precancerous spots, and certain skin cancers, and its supplement list is short and workable for most people. Only 3 ingredients are on file, none rated major, and all involve products applied to the skin rather than swallowed.”

About Uzara

What is Uzara?

  • Diarrhea
  • Stomach cramps
  • Menstrual cramps (dysmenorrhea)
  • Headaches
  • Digestive upset

Uzara is a traditional African root remedy used mainly for diarrhea and stomach cramps. Because it contains cardiac glycosides that can affect the heart, it should be used cautiously and for short periods only. Talk to a pharmacist or doctor before using it, especially if you have heart problems, are pregnant, or take heart medications.

Xysmalobium undulatum · Apocynaceae · Dried root · Liquid extract, tincture, tablets, drops

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

Uzara: dosing

There is no well-established standard dose for Uzara, and products vary in strength. The right amount depends on the specific preparation, such as drops, tincture, or tablets.The safest approach is to follow the directions on the product label and use it only for short periods. Do not exceed the recommended amount, since higher doses raise the risk of heart-related side effects.

Taking Uzara and Imiquimod Together: Common Questions

Is it safe to take Uzara with Imiquimod?
We do not list a known interaction between Uzara and Imiquimod. 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 Uzara and Imiquimod 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.
How was the Uzara and Imiquimod combination checked?
Interactions in our licensed database are recorded against drug classes. Imiquimod is filed under 1 classification, and Uzara has documented interactions with 6 drug classes — none of Imiquimod'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.
Does Uzara interact with any other medications?
Yes. Uzara has 133 documented drug interactions in our database — Imiquimod is simply not one of them. If you take anything else, it is worth checking each one; they are all listed on this page.
Does Imiquimod interact with any supplements?
Yes. Imiquimod has documented interactions with 3 supplements in our database — Uzara is not one of them. The Imiquimod interaction page linked on this page lists every one, ranked by severity.
