Drug & supplement interaction

Damiana + Ivermectin

Ivermectin brand names: Stromectol, Mectizan, Sklice, Soolantra.

No Known Interaction
Medically reviewed by · Updated July 2026 · Pair last verified Sep 13, 2026
The bottom line No known interaction

We found no known interaction between Damiana and Ivermectin 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 Ivermectin states a food rule worth keeping to, and 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.

Interaction report

Damiana and Ivermectin

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 Ivermectin and Damiana 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.

Damiana safety at a glance

Damiana overall Use caution Likely fine in food/tea amounts for most adults, but human safety data are limited.
Pregnancy Avoid Not enough safety data; avoid during pregnancy.
Breastfeeding Avoid Not enough safety data; avoid while breastfeeding.

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

How we checked

Why No Interaction Is Listed for Ivermectin

Interactions in our licensed database are recorded against drug classes, not just single drug names. Ivermectin is filed under 4 classifications — including topical drugs, p-glycoprotein substrates, oral drugs. Damiana has documented interactions with 1 drug class — the most serious being antidiabetes drugs (moderate) — and none of Ivermectin’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 to actually watch for

No Interaction Found — But Data Suggests Damiana and Ivermectin 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. One of them is worth acting on rather than waiting out — marked below.

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

Effects for Ivermectin come from the ADVERSE REACTIONS section of its FDA label; effects for Damiana come from the Natural Medicines adverse-effect record, quoted above. Where a percentage is shown, it is the share of 6,298 voluntary FDA FAERS reports for Ivermectin that mention that effect — a reporting proportion, not an incidence rate and not evidence the drug caused it. Wording is matched across sources by our own clinical vocabulary, so treat this as a prompt to pay attention, not a diagnosis.

How to take them

Some Ivermectin Products Have a Food Rule — Damiana Should Not Break It

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

Patients should take tablets on an empty stomach with water.

From the Dosage and Administration section of the FDA label we read for Ivermectin — 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.

About Damiana

What is Damiana?

Damiana
  • Low libido / aphrodisiac
  • Anxiety and stress
  • Mood and mild low energy
  • Digestive upset
  • Headache and general tonic

Damiana is a traditional herb most famous as an aphrodisiac and mild mood-lifter, but solid human evidence for any of its uses is very limited. It is generally well tolerated in the small amounts found in teas, but quality studies are lacking, so talk with your pharmacist or doctor before using it—especially if you are pregnant, breastfeeding, or have a health condition.

Turnera diffusa · Passifloraceae · Leaves (and sometimes stems) · Tea, capsules, tinctures, liquid extracts, dried leaf

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

Damiana: dosing

There is no well-established standard dose for damiana. The amount people use varies widely depending on the form—tea, capsule, or tincture.The safest approach is to follow the directions on the product label and not exceed the recommended amount. Because strength differs from product to product, a pharmacist can help you decide whether a particular product and dose make sense for you.If you try damiana, start low, watch how you feel, and stop if you notice side effects.

About Ivermectin

What Is Ivermectin Used For?

Brand names: Stromectol, Mectizan, Sklice, Soolantra

Ivermectin tablets (including Stromectol) are used to treat two parasitic infections: strongyloidiasis (a roundworm infection of the intestinal tract) and onchocerciasis (river blindness, caused by a parasitic worm spread by blackfly bites). These are prescription uses for serious infections.

Topical ivermectin lotion — sold under several names including RID One and Done, Head Lice Treatment Ivermectin Lotion, Scalp Care Lotions, and others — is applied to the scalp to treat head lice. A separate topical ivermectin cream (1%), available as Soolantra and ivermectin cream 1%, is used to treat the inflammatory pimple-like bumps of rosacea.

Most-Reported Side Effects for Ivermectin

From FAERS, the FDA’s public side-effect reporting system (6,298 reports, all brands). Reports are voluntary and are not proof the drug caused the effect.

Headache 647 reports
Asthenia 590 reports

Taking Damiana and Ivermectin Together: Common Questions

Is it safe to take Damiana with Ivermectin?
We do not list a known interaction between Damiana and Ivermectin. 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 Damiana and Ivermectin 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.
Should I take Damiana and Ivermectin at the same time of day?
At least one FDA label for a product containing Ivermectin says to take it on an empty stomach, and supplements are usually taken with a meal — so taking them together at breakfast is the easy mistake. Where that applies, keep Ivermectin on its own and move Damiana to a meal later in the day. Food instructions belong to the product rather than the ingredient, so check the directions on your own box. This is about absorption, not an interaction.
How was the Damiana and Ivermectin combination checked?
Interactions in our licensed database are recorded against drug classes. Ivermectin is filed under 4 classifications, and Damiana has documented interactions with 1 drug class — none of Ivermectin'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 Damiana interact with any other medications?
Yes. Damiana has 86 documented drug interactions in our database — Ivermectin 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 Ivermectin interact with any supplements?
Yes. Ivermectin has documented interactions with 58 supplements in our database — Damiana is not one of them. The Ivermectin interaction page linked on this page lists every one, ranked by severity.
