The bottom line No known interaction

We found no known interaction between Urine Therapy and Selegiline 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.

Urine Therapy and Selegiline

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 Selegiline and Urine Therapy 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.

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

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

What Selegiline’s Own FDA Label Lists

This is not an interaction — none of it involves Urine Therapy. These are the most notable effects listed in the ADVERSE REACTIONS section of Selegiline’s own FDA label, for the medication by itself. Knowing the drug’s own list makes it easier to work out the likely cause if something new turns up while you take both. 9 of them are worth acting on rather than waiting out — marked below.

  • Hallucinations Worth acting on mentioned in 6.5% of FDA reports for Selegiline
  • Mania or an unusually elevated mood Worth acting on
  • Serotonin syndrome Worth acting on
  • Thoughts of self-harm Worth acting on
  • Memory problems Worth acting on
  • Confusion Worth acting on
  • Seizures Worth acting on
  • Raised blood pressure Worth acting on
  • A higher chance of infection Worth acting on
  • A change in sex drive

Showing the 10 most notable of 32 label-listed effects — ranked by how unusual each one is across medicines generally, with serious effects weighted up.

From the ADVERSE REACTIONS section of the FDA label for Selegiline. Read the label on DailyMed › Where a percentage is shown, it is the share of 3,469 voluntary FDA FAERS reports for Selegiline that mention that effect — a reporting proportion, not an incidence rate and not evidence the drug caused it. Urine Therapy’s licensed record lists no adverse effects our clinical vocabulary could match, so there is no Urine Therapy side to compare — that is a limit of the record, not a statement that Urine Therapy has no side effects.

Where does our data come from?
  • Source: the Natural Medicines (TRC Healthcare) clinical database — the evidence-graded professional reference for herb & supplement interactions. Urine Therapy is not yet covered by that licensed database, so its write-up cites publicly available medical sources directly (see the references below).
  • Citation library: 103,510 references behind our interaction content, 65,311 of them resolved to verified PubMed/DOI sources. See every Urine Therapy reference on this page ↓
  • Freshness: we automatically re-check this combination every week — this pair was last verified September 20, 2026. The Urine Therapy and Selegiline records this page draws on were last updated June 22, 2026.
  • What “no known interaction” means: no documented interaction in the sources above — not a guarantee of safety. Supplements are studied far less than prescription drugs, so we say exactly what the evidence supports, and nothing more.

About Urine Therapy

What is Urine Therapy?

  • General wellness and detox beliefs
  • Skin conditions
  • Wound or rash care
  • Allergies
  • Cancer (alternative use)
  • Infections

Urine therapy is a practice of drinking or applying one's own urine, promoted in some traditional and alternative health circles. There is no reliable scientific evidence that it treats or prevents any disease, and drinking urine can cause harm. We do not recommend it.

Human urine (one's own) · Drinking fresh urine, skin application, gargling, eye or ear drops

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

Urine Therapy: dosing

There is no established or safe dose for urine therapy because it is not a recognized medical treatment. There are safer, evidence-based options for nearly every condition people use it for.

From our Urine Therapy monograph — the full record covers uses, side effects and every documented interaction.

About Selegiline

What Is Selegiline Used For?

Brand names: Carbex, Eldepryl, Emsam, Zelapar

Selegiline is used as an add-on treatment for people with Parkinson's disease who are already taking levodopa/carbidopa but are finding that the medication's effects are wearing off or becoming less reliable. It is not used alone — it only works as part of a combination approach.

In clinical studies, adding selegiline helped reduce the amount of daily levodopa needed, cut down on "off" time (periods when symptoms break through), and improved things like tremor, speech, movement, and overall daily function.

Most-Reported Side Effects for Selegiline

From FAERS, the FDA’s public side-effect reporting system (3,526 reports, all brands). Reports are voluntary and are not proof the drug caused the effect.

Hallucination 230 reports
Insomnia 206 reports
Dizziness 196 reports
Fall 186 reports
Application site erythema 185 reports
