Ashitaba and Lamivudine, Zidovudine

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 Lamivudine, Zidovudine and Ashitaba 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.

Ashitaba safety at a glance

Ashitaba overall Use caution Likely safe as a food, but supplement safety has not been well studied.
Pregnancy Avoid Not enough safety data, so avoid concentrated supplements during pregnancy.
Breastfeeding Avoid Not enough safety data, so avoid concentrated supplements while breastfeeding.

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

How we checked

Why No Interaction Is Listed for Lamivudine, Zidovudine

Interactions in our licensed database are recorded against drug classes, not just single drug names. Lamivudine, Zidovudine is filed under 4 classifications — including nucleoside reverse transcriptase inhibitors (nrtis), organic anion transporter 1 (oat1) substrates, hepatotoxic drugs. Ashitaba has documented interactions with 1 drug class — the most serious being cytochrome p450 1a2 (cyp1a2) substrates (moderate) — and none of Lamivudine, Zidovudine’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 Lamivudine, Zidovudine page

“Combivir (lamivudine plus zidovudine) treats HIV, and this list deserves real care, mostly because so many entries can compound strain on the liver. Zidovudine already asks a lot of that organ, and 38 of the 60 supplements on file, from ashwagandha to comfrey, add liver risk of their own.”

About Ashitaba

What is Ashitaba?

Ashitaba
  • General wellness and longevity
  • Antioxidant support
  • Heart and cholesterol health
  • Digestive and stomach support
  • Anti-inflammatory

Ashitaba is a leafy plant from Japan that is eaten as a vegetable and taken as a supplement for general health, antioxidant, and heart benefits. Most of the supporting research comes from laboratory and animal studies, so its real benefits in people are still uncertain. It appears generally well tolerated as a food, but talk to your pharmacist or doctor before using concentrated supplements.

Angelica keiskei · Apiaceae · Leaves, stems, and roots · Tea, capsules, powder, dried leaves, fresh vegetable, juice

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

Ashitaba: dosing

There is no well-established, standardized dose for Ashitaba supplements. Studies have used different forms and amounts, so a single "correct" dose has not been set.If you choose to use an Ashitaba product, follow the directions on the label and do not exceed the recommended amount.

About Lamivudine and Zidovudine

What Is Lamivudine and Zidovudine Used For?

Brand name: Combivir

Lamivudine and zidovudine tablets — sold as Combivir and under the generic name lamivudine and zidovudine — are used to treat HIV-1 (human immunodeficiency virus type 1) infection in adults, adolescents, and children who weigh at least 30 kg (about 66 lbs). This medicine is always used together with at least one other antiretroviral drug, not on its own.

The tablet combines two nucleoside analogue reverse transcriptase inhibitors (a class of antivirals that block a key step in HIV replication) into a single convenient dose. It does not cure HIV, but when taken correctly as part of a combination regimen, it helps control the virus.
