Bromelain 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 Bromelain 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.

Bromelain safety at a glance

Bromelain overall Use caution Generally well tolerated short-term, but evidence on long-term use is limited.
Pregnancy Avoid Not enough safety data, so it is best avoided during pregnancy.
Breastfeeding Avoid Safety while breastfeeding is unknown, so avoid it.

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

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. Bromelain has documented interactions with 2 drug classes — the most serious being anticoagulant/antiplatelet drugs (moderate) and tetracycline antibiotics (minor) — 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 Bromelain Itself Has Been Linked To

This is not an interaction — nothing below involves Ombitasvir, Paritaprevir Ritonavir. It is the side-effect record for Bromelain on its own, from the licensed Natural Medicines monograph. If something new turns up after you add Bromelain, this list is the first place to look. 4 entries are worth acting on rather than waiting out — marked below.

  • Trouble swallowing / Wheezing Worth acting on Additional detail

    “Immunoglobulin E (IgE)-mediated allergic reactions to bromelain may occur.

    If inhaled, bromelain may cause sensitization and allergic reactions such as asthma. In case reports of occupational inhalation of bromelain, additional allergic symptoms included difficulty swallowing, throat itching, eye irritation, and rhinitis.”

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 Bromelain

What is Bromelain?

Bromelain
  • Inflammation and swelling
  • Sinus and nasal congestion
  • Digestion support
  • Post-surgery or injury recovery
  • Joint pain
  • Allergic rhinitis

Bromelain is a group of protein-digesting enzymes from pineapple that people take mainly for inflammation, swelling, and sinus problems. Some early studies are promising, but the overall evidence is limited and far from conclusive. It is generally well tolerated short-term, but pregnant and breastfeeding people should avoid it, and anyone with a pineapple allergy or bleeding concerns should check with a pharmacist first.

Ananas comosus · Bromeliaceae · Stem and fruit of the pineapple · Capsules, tablets, powder, topical preparations

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

Bromelain: dosing

There is no single standardized dose of bromelain that has been firmly established for any condition. Bromelain products are often measured in units of enzyme activity (such as GDU or MCU), which can vary widely between brands, making it hard to compare products.Because of this, the best approach is to follow the directions on the product label and not exceed the recommended amount. A pharmacist can help you understand the strength of a particular product and whether it is appropriate for you.

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.
