Interaction report

Adrue and Peginterferon alfa-2b

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 Peginterferon alfa-2b and Adrue 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.

How we checked

Why No Interaction Is Listed for Peginterferon alfa-2b

Interactions in our licensed database are recorded against drug classes, not just single drug names. Peginterferon alfa-2b is filed under a single classification — hepatotoxic drugs. Adrue has documented interactions with 3 drug classes — the most serious being barbiturates (moderate), benzodiazepines (moderate) and cns depressants (moderate) — and none of Peginterferon alfa-2b’s classifications are among them.

Classification data comes from our licensed Natural Medicines dataset. A medication can belong to classes beyond those recorded there, so this describes how the check was run — it is not a safety guarantee.

From our pharmacist’s overview on the Peginterferon alfa-2b page

“Someone taking peginterferon alfa-2b (Peg-Intron) is usually treating hepatitis C, so the liver is already the organ under strain, and all 38 supplement interactions on file for this drug pile additional liver stress on top of it. That earns genuine caution.”

About Adrue

What is Adrue?

Nausea and vomiting
Digestive upset, gas, and diarrhea
Calming or sedative effect
Traditional use for fevers and infections

Adrue (Cyperus articulatus) is a sedge whose rhizome has long been used in traditional medicine for nausea and other stomach complaints, and as a mild calming agent. Solid human studies are lacking, so its real benefits and safe doses are not well established. Talk to a pharmacist or doctor before using it, and avoid it during pregnancy and breastfeeding.

Cyperus articulatus · Cyperaceae · Rhizome (underground stem) and tubers; sometimes the essential oil · Dried rhizome, powder, tea or decoction, traditional preparations, essential oil

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

Adrue: dosing

There is no established standardized dose for Adrue. Traditional use varies widely, and reliable human studies have not defined a safe and effective amount.If you choose to use a commercial product, follow the directions on the label and do not exceed them. A pharmacist can help you review the product and decide whether it is appropriate for you.Do not use Adrue as a substitute for medical care, especially for ongoing nausea, vomiting, diarrhea, or signs of infection, which may need proper diagnosis and treatment.

About Peginterferon Alfa-2b (PEG-Intron)

What Is Peginterferon Alfa-2b (PEG-Intron) Used For?

Brand names: Peg-Intron, ViraferonPeg

Peginterferon alfa-2b is used alone or in combination with ribavirin (a medication) to treat chronic (long-term) hepatitis C infection (swelling of the liver caused by a virus) in people who show signs of liver damage and who have not been treated with interferon alpha (medication similar to peginterferon alfa-2b) in the past. Peginterferon alfa-2b is in a class of medications called interferons. Peginterferon alfa-2b is a combination of interferon and polyethylene glycol, which helps the interferon stay active in your body for a longer period of time. Peginterferon alpha-2b works by decreasing the amount of hepatitis C virus (HCV) in the body. Peginterferon alfa-2b may not cure hepatitis C or prevent you from developing complications of hepatitis C such as cirrhosis (scarring) of the liver, liver failure, or liver cancer. Peginterferon alfa-2b may not prevent the spread of hepatitis C to other people.
