Drug & supplement interaction

Stevia + Latanoprost

Latanoprost brand names: Xalatan, Xelpros, Iyuzeh.

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 Stevia and Latanoprost 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.

Stevia and Latanoprost

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 Latanoprost and Stevia 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.

Stevia safety at a glance

Stevia overall Generally safe Purified stevia sweeteners are generally recognized as safe in typical food amounts.
Pregnancy Use caution Purified stevia in food amounts is likely acceptable, but whole-leaf or supplement doses are not well studied, so use caution.
Breastfeeding Use caution Food amounts of purified stevia are probably fine, but high-dose supplements lack safety data, so use caution.

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

What to actually watch for

No Interaction Found — But Data Suggests Stevia and Latanoprost May Share Several of the Same Side Effects

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.

Overlapping uses

What Latanoprost Is Prescribed For, and What Stevia Has Been Studied For

These two come up together because they touch the same health topic — not because they do the same job. Latanoprost is a prescription medicine with approved uses on its FDA label. Stevia is a supplement: what follows is what researchers have looked at it for, and how strong that evidence is.

Latanoprost is prescribed for: Latanoprost ophthalmic solution — available as Xalatan, Xelpros, and Iyuzeh — is used to reduce elevated intraocular pressure (IOP, the pressure inside your eye) in people with open-angle glaucoma or ocular hypertension (high eye pressure without glaucoma symptoms yet). Keeping eye pressure under control is important because high pressure is a major risk factor for damage to the optic nerve and loss of vision.

Stevia has been studied for:

  • Hypertension studied, not established Stevia has been studied for this. Natural Medicines rates the evidence: Insufficient Reliable Evidence To Rate Read what the research shows

    Stevia for hypertension

    It is unclear if oral stevia is beneficial in patients with hypertension; the available research is conflicting.

Effectiveness ratings and the research summaries above are the verbatim record from the Natural Medicines database, which grades evidence from “Effective” down to “Insufficient Reliable Evidence To Rate”. A rating below the top of that scale means researchers have looked at it — not that it works, and never that it can stand in for a prescribed medicine. Do not stop or replace Latanoprost on your own; if you are taking Stevia for the same health topic, tell your prescriber, especially if the medicine is being adjusted to a target.

About Stevia

What is Stevia?

  • Sugar substitute / sweetener
  • Blood sugar support in diabetes
  • Weight management
  • Blood pressure support
  • Reducing calorie intake

Stevia is a plant-based, calorie-free sweetener that is widely used as a sugar alternative and is considered safe in normal food amounts by major regulators. Purified stevia extracts have a good safety record, but evidence for medicinal benefits like lowering blood sugar or blood pressure is limited. Talk to your pharmacist or doctor before using stevia supplements for any health condition.

Stevia rebaudiana · Asteraceae · Leaves · Powder, liquid drops, tablets, granules, tea, and purified extracts (such as rebaudioside A and stevioside)

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

Stevia: dosing

There is no standard medicinal dose of stevia. As a sweetener, the right amount is simply enough to reach the sweetness you like, and a little goes a long way because it is much sweeter than sugar.For tabletop and food products, follow the directions on the label and stay within the recommended daily intake.

Taking Stevia and Latanoprost Together: Common Questions

Is it safe to take Stevia with Latanoprost?
We do not list a known interaction between Stevia and Latanoprost. 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 Stevia and Latanoprost have any of the same side effects?
Yes — our sources link each of them separately to 4 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.
Are Stevia and Latanoprost used for the same thing?
They overlap in purpose, which usually means the real question is whether you need both rather than whether they are safe together. This page lists the shared uses and how strong the evidence is for Stevia in each. That is a conversation for your prescriber, especially if Latanoprost is being adjusted to a target.
Does Stevia interact with any other medications?
Yes. Stevia has 259 documented drug interactions in our database — Latanoprost is simply not one of them. If you take anything else, it is worth checking each one; they are all listed on this page.
