Lavender Cotton + Naltrexone
Naltrexone brand names: Trexan, Depade, Vivitrol.
We found no known interaction between Lavender Cotton and Naltrexone 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.
Lavender Cotton and Naltrexone
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 Naltrexone and Lavender Cotton 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 Lavender Cotton at all — not against Naltrexone, 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.

See Every Supplement That Interacts With Naltrexone
This page covers Lavender Cotton only. If you take other supplements — a multivitamin, a sleep aid, something for joints — the Naltrexone page lists 56 supplements it has a documented interaction with, worst first, each one explained.
The most serious there right now: Activated Charcoal (major), Beer (major), Siberian Cocklebur (major), Wine (major) and Ashwagandha (moderate).
By severity: 4 major · 43 moderate · 9 minor.
From our pharmacist’s overview on the Naltrexone page
“The single biggest risk on this page is to your liver. Naltrexone (Vivitrol, Depade), prescribed for alcohol and opioid dependence, carries its own warnings about liver stress at higher doses, and 38 of the 56 supplements here share that liability, led by Siberian cocklebur, a major-rated entry tied to outright liver failure.”

Where does our data come from?
- Source: the Natural Medicines (TRC Healthcare) clinical database — the evidence-graded professional reference for herb & supplement interactions. Lavender Cotton 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 Lavender Cotton reference on this page ↓
- Freshness: we automatically re-check this combination every week — this pair was last verified September 13, 2026. The Lavender Cotton and Naltrexone 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 Lavender Cotton
What is Lavender Cotton?
- Digestive upset
- Intestinal worms (traditional)
- Insect repellent
- Minor skin irritation
- Menstrual discomfort (traditional)
Lavender cotton (Santolina chamaecyparissus) is a fragrant Mediterranean shrub used in folk medicine for digestion, worms, and as an insect repellent, but there is very little modern human research to support any of these uses. Because reliable safety and effectiveness data are lacking, it is best used cautiously and avoided in pregnancy and breastfeeding. Talk to your pharmacist or doctor before trying it.
Santolina chamaecyparissus · Asteraceae · Flowering tops, leaves, and essential oil · Dried herb, tea/infusion, essential oil, topical preparations
An interaction check asks whether these two react with each other — it does not ask whether Lavender Cotton is a good idea for someone in your situation. Here is what our Lavender Cotton record says about it on its own.
Lavender Cotton: dosing
There is no established or standardized dose for lavender cotton. Traditional use as a mild tea does not mean a safe dose has been scientifically defined, and the essential oil is much more concentrated than the dried herb.If you choose to use a product, follow the directions on the label and do not exceed them. Essential oils should be kept out of reach of children and never taken by mouth without professional guidance.

About Naltrexone
What Is Naltrexone Used For?
Brand names: Trexan, Depade, Vivitrol
Naltrexone Hydrochloride tablets are used to treat alcohol dependence and to block the effects of opioids in people with opioid dependence. The extended-release injectable suspension — sold as Vivitrol and also available as a generic injectable — is used to treat alcohol dependence and to prevent relapse to opioid dependence after a person has completed opioid detoxification.
All formulations are meant to be part of a broader treatment plan that includes counseling and other support — naltrexone works best when it is not used alone.
Most-Reported Side Effects for Naltrexone
From FAERS, the FDA’s public side-effect reporting system (40,504 reports, all brands). Reports are voluntary and are not proof the drug caused the effect.
