Drug & supplement interaction

Animal-assisted Therapy + Perphenazine

Perphenazine brand name: Trilafon.

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 Animal-assisted Therapy and Perphenazine 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

Animal-assisted Therapy and Perphenazine

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

Worth understanding: our licensed dataset holds no drug-interaction record for Animal-assisted Therapy at all — not against Perphenazine, 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.

Animal-assisted 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.

Animal-assisted Therapy safety at a glance

Animal-assisted Th... overall Use caution Generally low-risk when supervised, but allergies, infection risk, and animal safety must be considered.
Pregnancy Use caution Usually fine, but be careful around animals that may carry infections; check with your doctor.
Breastfeeding Use caution No direct concern for the baby, but practice good hygiene around animals.

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 Animal-assisted Therapy and Perphenazine 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 having Animal-assisted 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. One of them is worth acting on rather than waiting out — marked below.

  • A higher chance of infection Worth acting on Additional detail

    Animal-assisted Therapy

    “Animal-assisted therapy (AAT) is generally well tolerated, with few adverse effects reported. However, a thorough evaluation of safety outcomes has not been conducted.

    Serious Adverse Effects (Rare):

    Transmission of zoonotic diseases to patients, particularly those prone to infection. With equine therapy, falling and low back pain.”

    Perphenazine

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

Reported for Animal-assisted Therapy but not commonly for Perphenazine: back pain.

Effects for Perphenazine come from the ADVERSE REACTIONS section of its FDA label; effects for Animal-assisted Therapy 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.

Overlapping uses

What Perphenazine Is Prescribed For, and What Animal-assisted Therapy Has Been Studied For

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

Perphenazine is prescribed for: Perphenazine tablets are approved to treat schizophrenia in adults. They are also used to control severe nausea and vomiting in adults when other measures are not enough. Perphenazine has not been shown effective for managing behavioral problems in patients with intellectual disabilities, and it is not approved for dementia-related psychosis in elderly patients.

Animal-assisted Therapy has been studied for:

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

    Animal-assisted Therapy for dementia

    It is unclear if animal-assisted therapy (AAT) is beneficial in dementia.

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

    Animal-assisted Therapy for schizophrenia

    It is unclear if animal-assisted therapy (AAT) is beneficial in schizophrenia.

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

About Animal-assisted Therapy

What is Animal-assisted Therapy?

  • Anxiety and stress
  • Depression and low mood
  • Loneliness and social isolation
  • Pain and comfort during hospital stays
  • Support for children with autism or developmental needs
  • Rehabilitation and physical therapy motivation

Animal-assisted therapy uses trained animals, guided by professionals, to support emotional and physical well-being. Many people find it comforting and it appears generally low-risk, but high-quality evidence for treating specific medical conditions is still limited. It is best used alongside, not instead of, standard medical care.

Not applicable (this is a therapy, not an herb or supplement) · Sessions with trained therapy animals such as dogs, horses, cats, or other animals, guided by a handler or health professional

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

Animal-assisted Therapy: dosing

There is no standard dose for animal-assisted therapy. The number, length, and frequency of sessions are usually tailored to the person and their goals by the therapist or program running it.If you are interested in AAT, ask about programs run through reputable hospitals, clinics, or certified therapy-animal organizations. A pharmacist or doctor can help you decide if it is a reasonable addition to your care, especially if you have allergies or a weakened immune system.

Having Animal-assisted Therapy While Taking Perphenazine: Common Questions

Is it safe to have Animal-assisted Therapy while taking Perphenazine?
We do not list a known interaction between Animal-assisted Therapy and Perphenazine. 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 Animal-assisted Therapy and Perphenazine 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.
Are Animal-assisted Therapy and Perphenazine 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 Animal-assisted Therapy in each. That is a conversation for your prescriber, especially if Perphenazine is being adjusted to a target.
Does Perphenazine interact with any supplements?
Yes. Perphenazine has documented interactions with 147 supplements in our database — Animal-assisted Therapy is not one of them. The Perphenazine interaction page linked on this page lists every one, ranked by severity.
