The bottom line No known interaction

We found no known interaction between Anise and Oxandrolone 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.

Anise and Oxandrolone

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 Oxandrolone and Anise 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 Oxandrolone

Interactions in our licensed database are recorded against drug classes, not just single drug names. Oxandrolone is filed under a single classification — oral drugs. Anise has documented interactions with 11 drug classes — the most serious being antidiabetes drugs (moderate), caffeine (moderate) and codeine (moderate) — and none of Oxandrolone’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.

Keep it in perspective

What to actually watch for

What Anise Itself Has Been Linked To

This is not an interaction — nothing below involves Oxandrolone. It is the side-effect record for Anise on its own, from the licensed Natural Medicines monograph. If something new turns up after you add Anise, this list is the first place to look. 2 entries are worth acting on rather than waiting out — marked below.

  • Wheezing / An allergic reaction Worth acting on Additional detail

    “Anise can cause allergic reactions in sensitive individuals. Orally or by inhalation, anise can cause rhinoconjunctivitis, occupational asthma, and anaphylaxis. Topically, anise can cause contact dermatitis, rhinitis, and asthma. Contact dermatitis and cheilitis have also been reported following the use of toothpaste containing anethole, a constituent of anise.”

From our pharmacist’s overview on the Oxandrolone page

“Every supplement known to interact with oxandrolone (Oxandrin, Anavar) works the same basic way: it can change how much of the tablet actually reaches your bloodstream. Oxandrolone is an anabolic steroid prescribed to rebuild weight and muscle after surgery, severe illness, or long-term wasting, so a dose that under-absorbs means the r…”

About Anise

What is Anise?

Anise
  • Digestive upset and bloating
  • Cough and respiratory complaints
  • Sore throat
  • Menstrual discomfort
  • Flavoring agent

Anise is a fragrant, licorice-flavored seed used for centuries to ease digestion and soothe coughs. Most of its health claims are based on tradition and small or laboratory studies rather than strong human research, so evidence is limited. It is generally safe as a food and tea for most adults, but the concentrated essential oil should be used carefully and avoided in pregnancy.

Pimpinella anisum · Apiaceae · Seeds (fruit) and essential oil · Whole or ground seeds, tea, capsules, extracts, essential oil

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

Anise: dosing

There is no official standardized dose for anise. Amounts vary widely depending on the form, such as seeds steeped as tea, capsules, or extracts.The best approach is to follow the directions on the product label and not exceed the recommended amount.

From our Anise monograph — the full record covers uses, side effects and every documented interaction.

About Oxandrolone

What Is Oxandrolone Used For?

Brand names: Oxandrin, Anavar

  • Oxandrolone is used with a diet program to cause weight gain in people who have lost too much weight due to surgery, injury, chronic (long-lasting) infections, trauma, or who are underweight for unknown reasons. Oxandrolone is also used to treat bone pain in people with osteoporosis (a condition in which the bones become thin and weak and break easily) and to prevent certain side effects in people who take corticosteroids (a group of medications used to treat many conditions that involve inflammation or swelling of part of the body) for a long time. Oxandrolone is in a class of medications called androgenic hormones. It works by increasing the amount of protein made by the body. This protein is used to build more muscle and increase body weight.
