Jewelweed 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 Jewelweed 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 Jewelweed 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.

Jewelweed safety at a glance

Jewelweed overall Use caution Generally used on the skin with few reported problems, but it is not well studied and should not be taken by mouth without guidance.

What Selegiline’s Own FDA Label Lists

This is not an interaction — none of it involves Jewelweed. 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. Jewelweed’s licensed record lists no adverse effects our clinical vocabulary could match, so there is no Jewelweed side to compare — that is a limit of the record, not a statement that Jewelweed has no side effects.

About Jewelweed

What is Jewelweed?

  • Poison ivy and poison oak rashes
  • Skin itching and irritation
  • Insect bites and stings
  • Nettle stings
  • Minor skin inflammation

Jewelweed is a wild plant traditionally rubbed on the skin to soothe poison ivy rashes, bug bites, and itching. Good scientific evidence is limited and mostly weak, so it should not replace proven treatments. It is generally used on the skin, and you should always check with a pharmacist or doctor before using it, especially during pregnancy or breastfeeding.

Impatiens capensis · Balsaminaceae · Stems, leaves, and the sap (juice) from the crushed plant · Fresh crushed plant, salves, soaps, lotions, sprays, frozen cubes, and tinctures

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

Jewelweed: dosing

There is no official or standardized dose for jewelweed. People traditionally crush the fresh stems and leaves and rub the juice directly on the affected skin, and many use commercial salves, soaps, or sprays.If you use a store-bought product, follow the directions on the label.

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
