Interaction report

Cabbage and Ombitasvir, Paritaprevir Ritonavir

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 Ombitasvir, Paritaprevir Ritonavir and Cabbage 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 Ombitasvir, Paritaprevir Ritonavir

Interactions in our licensed database are recorded against drug classes, not just single drug names. Ombitasvir, Paritaprevir Ritonavir is filed under 7 classifications — including cytochrome p450 3a4 (cyp3a4) inhibitors, p-glycoprotein substrates, cytochrome p450 3a4 (cyp3a4) substrates. Cabbage has documented interactions with 6 drug classes — the most serious being acetaminophen (tylenol, others) (moderate), antidiabetes drugs (moderate) and cytochrome p450 1a2 (cyp1a2) substrates (moderate) — and none of Ombitasvir, Paritaprevir Ritonavir’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.

What to actually watch for

What Cabbage Itself Has Been Linked To

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

An allergic reaction Worth acting on Additional detail
“Topically, cabbage may cause contact dermatitis. Allergic reactions to cabbage-related vegetables are rare. However, anaphylactic reactions to broccoli and cauliflower have been reported. Because the surface proteins believed to cause allergic reactions to brocolli are also found in cabbage, some patients allergic to brocolli or other vegetables in the Brassicaceae family may also be allergic to cabbage.”

“Some preliminary clinical research shows that application of cabbage leaf wraps to knee joints for at least 2 hours daily for 4 weeks is generally well-tolerated. Of the 27 patients using cabbage leaf wraps in this study, one patient reported an itching and burning sensation during the application. This patient was later found to have shingles, which may explain the adverse event.”

Lactation Likely Safe

From our pharmacist’s overview on the Ombitasvir, Paritaprevir Ritonavir page

“Technivie (ombitasvir, paritaprevir, and ritonavir) treats hepatitis C, and because a cure depends on holding steady drug levels for the whole course, this list warrants genuine care. Most of the 154 ingredients on file touch the CYP3A4 enzyme pathway, meaning they can push the drug's blood levels up or down.”

About Cabbage

What is Cabbage?

Breast engorgement during breastfeeding
Joint pain and swelling (topical)
Digestive and stomach upset
General nutrition and antioxidant support
Skin and minor inflammation (topical)

Cabbage is a nutritious, low-calorie vegetable that is safe to eat as food and is sometimes applied to the skin as a leaf wrap for breast engorgement or sore joints. Most medicinal claims are based on tradition or limited research, with the strongest (though still modest) evidence being for cooling cabbage leaves on engorged breasts. Talk to your pharmacist or doctor before using cabbage in large amounts or as a treatment.

Brassica oleracea · Brassicaceae (Cruciferae) · Leaves (head); also juice and extracts · Fresh vegetable, raw leaves, juice, fermented (sauerkraut), capsules, and topical leaf wraps

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

Cabbage: dosing

There is no standardized medicinal dose for cabbage. As a food, it can be eaten freely as part of a balanced diet.For breast engorgement, a common traditional approach is to apply clean, chilled cabbage leaves to the breasts for a limited time and remove them once they wilt or symptoms ease. For supplements or juice, follow the product label.

About Ombitasvir, Paritaprevir, and Ritonavir

What Is Ombitasvir, Paritaprevir, and Ritonavir Used For?

Brand name: Technivie

The combination of ombitasvir, paritaprevir, and ritonavir is usually used in combination with ribavirin (Copegus, Rebetol), but sometimes it is used alone to treat a certain type of chronic (long-term) hepatitis C infection (swelling of the liver caused by a virus). Ombitasvir is a hepatitis C virus (HCV) NS5A inhibitor. It works by stopping the virus that causes hepatitis C from spreading inside the body. Paritaprevir is a protease inhibitor. It works by decreasing the amount of HCV in the body. Ritonavir is a protease inhibitor. It helps to increase the amount of paritaprevir in the body so that the medication will have a greater effect. It is not known if ombitasvir, paritaprevir, or ritonavir prevent the spread of hepatitis C to other people.
