Yerba Mate and Ombitasvir, Paritaprevir Ritonavir

Here is the interaction we found between these two, with the evidence behind it.

Minor

CYTOCHROME P450 3A4 (CYP3A4) SUBSTRATES

Why this applies to Ombitasvir, Paritaprevir Ritonavir

Ombitasvir, Paritaprevir Ritonavir falls under CYTOCHROME P450 3A4 (CYP3A4) SUBSTRATES — the group Yerba Mate interacts with.

Theoretically, yerba mate might increase the levels and clinical effects of CYP3A4 substrates.
In vitro research shows that yerba mate extract inhibits CYP3A4 enzymes. Theoretically, taking yerba mate may increase levels and adverse effects of CYP3A4 substrates.
Severity Minor Likelihood Possible Evidence D

Interaction has been documented in animal or in lab research, or the interaction has been documented in humans but is limited to case reports or conflicting clinical research exists.

Dr. Brian Staiger, PharmD, BCPS
Dr. Brian Staiger explains PharmD, Clinical Pharmacist

Here's the gist for your hepatitis C combo (Technivie). In test-tube studies, yerba mate appears to gently slow down an enzyme called CYP3A4, which is one of the pathways your body uses to clear parts of this medicine. If that enzyme is slowed, levels of the drug could in theory drift a little higher, which might mean more chances for side effects like tiredness, nausea, itching, or trouble sleeping.

The good news: this is only a theoretical concern based on lab work, not real-world cases, and it's rated as minor. A regular cup of mate likely won't cause problems. Still, because this regimen already leans on ritonavir to nudge drug levels up, it's worth a quick chat with your pharmacist or doctor before adding concentrated mate supplements.

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 Yerba Mate

What is Yerba Mate?

Yerba Mate
  • Energy and alertness
  • Weight loss
  • Mental focus
  • Digestive support
  • Antioxidant support

Yerba mate is a caffeine-containing herbal beverage from South America that is widely enjoyed for its stimulating, coffee-like effects. While it is rich in antioxidants and is being studied for weight, blood sugar, and cholesterol, strong human evidence for most health claims is limited. Drinking very hot mate over many years has been linked to higher risk of certain cancers, so enjoy it warm and in moderation.

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.
