Patchouli Oil and Lacosamide

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 Lacosamide 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 Lacosamide, 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 safety at a glance

Patchouli Oil overall Use caution Generally considered safe for topical and aromatherapy use when diluted, but can irritate skin and should not be swallowed.
Pregnancy Avoid Safety is not established, so avoid use during pregnancy unless cleared by your doctor.
Breastfeeding Avoid Not enough safety information exists, so it is best avoided while breastfeeding.

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

What Lacosamide’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 Lacosamide’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. 5 of them are worth acting on rather than waiting out — marked below.

  • Seizures Worth acting on mentioned in 22.4% of FDA reports for Lacosamide
  • Unsteadiness Worth acting on
  • Fainting Worth acting on
  • A severe skin reaction Worth acting on
  • An allergic reaction Worth acting on
  • Blurred vision
  • Drowsiness mentioned in 4.0% of FDA reports for Lacosamide
  • Trouble sleeping
  • Dizziness mentioned in 4.5% of FDA reports for Lacosamide
  • Tiredness mentioned in 3.9% of FDA reports for Lacosamide

Showing the 10 most notable of 14 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 Lacosamide. Read the label on DailyMed › Where a percentage is shown, it is the share of 36,995 voluntary FDA FAERS reports for Lacosamide 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.
