Drug & supplement interaction

Fish Therapy + Secukinumab

Secukinumab brand name: Cosentyx.

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 Fish Therapy and Secukinumab 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.

Fish Therapy and Secukinumab

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 Secukinumab and Fish Therapy in our sources. This does not guarantee that the combination is completely free of risk — research on Fish Therapy alongside specific medications may be limited.

Worth understanding: our licensed dataset holds no drug-interaction record for Fish Therapy at all — not against Secukinumab, and not against any other medication we track. This verdict therefore rests on the absence of any recorded data, not on research that looked at this combination and found nothing. We cannot rule an interaction out.

Fish Therapy is a treatment rather than something you take. Tell whoever provides it which medicines you use, and ask your prescriber whether it is appropriate for your health and treatment. 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.

Fish Therapy safety at a glance

Fish Therapy overall Use caution Hygiene and infection risks make this a cautious choice, especially with shared water.
Pregnancy Use caution Not studied in pregnancy; avoid due to infection risk unless cleared by your doctor.
Breastfeeding Use caution No safety data; infection risk makes caution reasonable while breastfeeding.

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 Fish Therapy and Secukinumab 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 having Fish Therapy while taking the medicine can make those effects more likely to turn up, and harder to pin on one or the other if they do. 2 of them are worth acting on rather than waiting out — marked below.

  • Liver problems / A higher chance of infection Worth acting on Additional detail

    Fish Therapy

    “Multiple case reports suggest that fish therapy can increase the risk for bacterial infection. Studies of fish therapy water have identified multiple bacteria capable of causing disease. It is currently not possible to adequately sterilize the water without killing the fish. Additionally, when performed in a spa or salon setting, pedicure tubs cannot be adequately cleaned when fish are present.”

Reported for Fish Therapy but not commonly for Secukinumab: swelling.

Effects for Secukinumab come from the ADVERSE REACTIONS section of its FDA label; effects for Fish Therapy come from the Natural Medicines adverse-effect record, quoted above. Where a percentage is shown, it is the share of 158,767 voluntary FDA FAERS reports for Secukinumab 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.

Overlapping uses

What Secukinumab Is Prescribed For, and What Fish Therapy Has Been Studied For

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

Secukinumab is prescribed for: Cosentyx is used to treat several immune-related conditions. In adults and children 6 and older, it treats moderate to severe plaque psoriasis. In adults and children 2 and older, it treats active psoriatic arthritis. For ankylosing spondylitis (spinal inflammation), it is approved for adults and children 12 and older.

Read the rest of what Secukinumab is prescribed for

It also treats active non-radiographic axial spondyloarthritis (early spinal inflammation without visible joint damage on X-ray) in adults, and enthesitis-related arthritis (inflammation where tendons attach to bone) in children 4 and older. Moderate to severe hidradenitis suppurativa (a painful skin condition with recurring boils) is also an approved use for adults and children 12 and older. Cosentyx intravenous (IV) infusion is approved only for adults with psoriatic arthritis, ankylosing spondylitis, and non-radiographic axial spondyloarthritis. Subcutaneous (under-the-skin) injection covers the full range of approved uses for both adults and children.

Fish Therapy has been studied for:

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

    Fish Therapy for psoriasis

    One small, retrospective study in adults with psoriasis shows that undergoing whole body fish therapy for 2 hours each day for 3 weeks improves the Psoriasis Area Severity Index (PASI) score by 72% when compared with baseline. Patients also reported subjective satisfaction with the treatment. The validity of these findings is limited by the use of retrospective chart review and the lack of a comparator group.

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

About Fish Therapy

What is Fish Therapy?

  • Psoriasis
  • Skin exfoliation and smoothing
  • Eczema and dry skin
  • Cosmetic foot care (pedicure)
  • General relaxation

Fish therapy (also called ichthyotherapy or a 'fish pedicure') uses small Garra rufa fish to nibble away dead skin, and it is mostly used cosmetically or for skin conditions like psoriasis. Evidence that it treats any medical condition is very limited, and there are real infection and hygiene concerns. If you have a skin condition, talk with a dermatologist before trying it.

Live fish (commonly Garra rufa); the whole animal used in skin-immersion baths · Spa fish baths (foot or full-body immersion with Garra rufa fish)

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

Fish Therapy: dosing

There is no standard 'dose' for fish therapy, since it is a spa procedure rather than a supplement you take. Sessions are usually a set number of minutes in a spa setting.If you choose to try it, only use a reputable, licensed facility that follows strict hygiene rules, and never share water with someone who has a skin infection.

Having Fish Therapy While Taking Secukinumab: Common Questions

Is it safe to have Fish Therapy while taking Secukinumab?
We do not list a known interaction between Fish Therapy and Secukinumab. 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 Fish Therapy and Secukinumab have any of the same side effects?
Yes — our sources link each of them separately to 3 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 Fish Therapy and Secukinumab 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 Fish Therapy in each. That is a conversation for your prescriber, especially if Secukinumab is being adjusted to a target.
