Interaction report

Chinese Mallow and Naltrexone Hydrochloride, Oxycodone Hydrochloride

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 Hydrochloride, Oxycodone Hydrochloride and Chinese Mallow 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.

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.

From our pharmacist’s overview on the Naltrexone Hydrochloride, Oxycodone Hydrochloride page

“Alcohol tops this list. Beer and wine both carry major, well-documented interactions with Troxyca ER (naltrexone and oxycodone hydrochloride), an extended-release opioid, because adding a second sedative to an opioid can slow breathing, not just deepen drowsiness.”

About Chinese Mallow

What is Chinese Mallow?

  • Constipation
  • Digestive upset
  • Urinary problems
  • Cough and sore throat
  • Skin soothing (topical)

Chinese Mallow (Malva verticillata) is a leafy plant used in traditional Chinese and Asian medicine, mostly for constipation, urinary complaints, and as a soothing demulcent. Strong scientific evidence in humans is lacking, so its benefits are mostly based on traditional use and early research. Talk with your pharmacist or doctor before using it, and avoid it during pregnancy and breastfeeding.

Malva verticillata · Malvaceae · Seeds, leaves, and flowers · Tea, dried herb, powders, capsules, and topical preparations

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

Chinese Mallow: dosing

There is no established standard dose for Chinese Mallow. Traditional preparations vary widely depending on the part used and the form, and reliable human dosing studies are lacking.If you choose to use it, follow the directions on the product label and do not exceed the suggested amount. Because product strength and quality can differ, it is a good idea to review the label with a pharmacist who can help you decide if it is appropriate for you.
