Immortelle 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 Immortelle 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 Immortelle 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.

Immortelle safety at a glance

Immortelle overall Use caution Generally used in food and tea amounts, but human safety data for supplements is limited.
Pregnancy Avoid Not enough safety information, so it is best avoided during pregnancy.
Breastfeeding Avoid Safety while breastfeeding is unknown, so avoid unless cleared by your doctor.

Safety guidance is general; always confirm with your pharmacist or doctor for your situation.

What Selegiline’s Own FDA Label Lists

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

About Immortelle

What is Immortelle?

  • Digestive and liver support
  • Skin health and wound care
  • Mild inflammation
  • Antioxidant support
  • Cough and respiratory complaints

Immortelle (Helichrysum) is a Mediterranean flowering herb used traditionally for digestion, skin, and mild inflammation. Human evidence for these uses is very limited, so it should be seen as a traditional remedy rather than a proven treatment. Talk with your pharmacist or doctor before using it, especially if you are pregnant, breastfeeding, or taking other medicines.

Helichrysum arenarium · Asteraceae · Flowers (flower heads) and essential oil · Tea, dried flowers, tincture, capsules, essential oil

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

Immortelle: dosing

There is no official, standardized dose of immortelle. Traditional use involves brewing the dried flowers as a tea or using a tincture, but the amount of active compounds can vary a lot between products.If you use a commercial supplement, follow the directions on the product label and do not exceed them. Essential oil is for external or aromatherapy use only and must be diluted.

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
