Drug & supplement interaction

Krill Oil + Loteprednol

Loteprednol brand names: Lotemax, Alrex.

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 Krill Oil and Loteprednol 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.

Interaction report

Krill Oil and Loteprednol

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 Loteprednol and Krill Oil 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.

What to actually watch for

No Interaction Found — But Data Suggests Krill Oil and Loteprednol 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 Loteprednol Is Prescribed For, and What Krill Oil Has Been Studied For

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

Loteprednol is prescribed for: Loteprednol ophthalmic suspension is used to treat steroid-responsive inflammatory conditions of the eye, including allergic conjunctivitis, iritis (inflammation inside the eye), cyclitis, superficial punctate keratitis, herpes zoster keratitis, acne rosacea affecting the eye, and certain types of infectious conjunctivitis — when reducing swelling and inflammation is important enough to accept the risks of steroid use. Loteprednol ophthalmic suspension is also used to treat inflammation after eye surgery. Eysuvis (loteprednol etabonate ophthalmic suspension) is specifically indicated for short-term use of up to two weeks for these inflammatory conditions.

Krill Oil has been studied for:

  • Dry eye Natural Medicines rates the evidence for Krill Oil: Possibly Effective Read what the research shows

    Krill Oil for dry eye

    Taking oral krill oil seems to reduce dry eye symptoms.

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 Loteprednol on your own; if you are taking Krill Oil for the same health topic, tell your prescriber, especially if the medicine is being adjusted to a target.

About Krill Oil

What is Krill Oil?

Krill Oil
  • Heart and cholesterol support
  • High triglycerides
  • Joint pain and inflammation
  • Brain and eye health
  • PMS symptoms
  • General omega-3 supplementation

Krill oil is a source of omega-3 fatty acids (EPA and DHA) bound to phospholipids, which may help absorption. It is most studied for lowering triglycerides and supporting heart health, but the evidence for many other uses is limited. It is generally well tolerated, but people with shellfish allergy should avoid it, and anyone pregnant, breastfeeding, or on blood thinners should check with a pharmacist or doctor first.

Euphausia superba · Euphausiidae · Oil extracted from the whole krill · Softgel capsules, liquid

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

Krill Oil: dosing

There is no single official or standardized dose of krill oil. Products vary in how much EPA and DHA they provide per capsule, so two products may not be equal even at the same number of capsules.The best approach is to follow the directions on the product label and to choose a reputable brand.

Taking Krill Oil and Loteprednol Together: Common Questions

Is it safe to take Krill Oil with Loteprednol?
We do not list a known interaction between Krill Oil and Loteprednol. 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 Krill Oil and Loteprednol have any of the same side effects?
Yes — our sources link each of them separately to 2 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 Krill Oil and Loteprednol 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 Krill Oil in each. That is a conversation for your prescriber, especially if Loteprednol is being adjusted to a target.
Does Krill Oil interact with any other medications?
Yes. Krill Oil has 208 documented drug interactions in our database — Loteprednol is simply not one of them. If you take anything else, it is worth checking each one; they are all listed on this page.
