Patchouli Oil and Cyclophosphamide

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 Cyclophosphamide and Patchouli Oil 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 Patchouli Oil at all — not against Cyclophosphamide, 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.

Patchouli Oil overall Use caution Generally considered safe for topical and aromatherapy use when diluted, but can irritate skin and should not be swallowed.

What Cyclophosphamide’s Own FDA Label Lists

This is not an interaction — none of it involves Patchouli Oil. These are the most notable effects listed in the ADVERSE REACTIONS section of Cyclophosphamide’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. 10 of them are worth acting on rather than waiting out — marked below.

  • A low white blood cell count Worth acting on mentioned in 14.3% of FDA reports for Cyclophosphamide
  • Hearing loss Worth acting on
  • Severe muscle breakdown Worth acting on
  • Low sodium Worth acting on
  • Low blood sugar Worth acting on
  • A slow heartbeat Worth acting on
  • A heart attack Worth acting on
  • Blood clots Worth acting on
  • Pancreatitis Worth acting on
  • Yellowing of the skin or eyes Worth acting on

Showing the 10 most notable of 56 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 Cyclophosphamide. Read the label on DailyMed › Where a percentage is shown, it is the share of 176,005 voluntary FDA FAERS reports for Cyclophosphamide that mention that effect — a reporting proportion, not an incidence rate and not evidence the drug caused it. Patchouli Oil’s licensed record lists no adverse effects our clinical vocabulary could match, so there is no Patchouli Oil side to compare — that is a limit of the record, not a statement that Patchouli Oil has no side effects.

About Patchouli Oil

What is Patchouli Oil?

  • Aromatherapy and relaxation
  • Skin care
  • Insect repellent
  • Fragrance and perfume
  • Antimicrobial use
  • Mood support

Patchouli oil is an essential oil pressed from the leaves of the patchouli plant, used mainly for its strong, earthy scent in aromatherapy, skin products, and perfumes. Most claimed health benefits come from laboratory studies rather than solid human trials, so its real-world value remains unproven. Like all essential oils, it should be diluted before skin use and never swallowed unless directed by a qualified professional.

Pogostemon cablin · Lamiaceae · Leaves (dried and steam-distilled essential oil) · Essential oil, diluted oil blends, soaps, lotions, perfumes, incense

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

Patchouli Oil: dosing

There is no established standard dose for patchouli oil, and it is not meant to be taken by mouth. For topical use, it is typically diluted to a small percentage in a carrier oil before being applied to the skin.For aromatherapy, a few drops may be added to a diffuser according to the product directions.

About Cyclophosphamide

What Is Cyclophosphamide Used For?

Brand names: Cytoxan, Neosar

Cyclophosphamide is used to treat many types of cancer in adults and children, including malignant lymphomas (such as Hodgkin's disease and Burkitt's lymphoma), multiple myeloma, several forms of leukemia, breast cancer, ovarian cancer, neuroblastoma, retinoblastoma, and advanced mycosis fungoides (a type of skin lymphoma). It is often given alongside other chemotherapy drugs rather than on its own.

Oral and injectable powder formulations (but not the Cyclophosphamide Injection solution concentrate) are also approved for minimal change nephrotic syndrome — a kidney condition — in children who have not responded well to, or cannot tolerate, steroid therapy. The injectable solution concentrate is approved for adult patients only due to its alcohol content, and is not approved for use in children.

Most-Reported Side Effects for Cyclophosphamide

From FAERS, the FDA’s public side-effect reporting system (176,005 reports, all brands). Reports are voluntary and are not proof the drug caused the effect.

Febrile neutropenia 14,532 reports
Neutropenia 10,580 reports
Fever 9,242 reports
Disease progression 8,093 reports
Pneumonia 6,669 reports
