Feingold Diet 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 Feingold Diet in our sources. This does not guarantee that the combination is completely free of risk — research on Feingold Diet alongside specific medications may be limited.

Worth understanding: our licensed dataset holds no drug-interaction record for Feingold Diet at all — not against Ombitasvir, Paritaprevir Ritonavir, and not against any other medication we track. This verdict therefore rests on the absence of any recorded data, not on research that looked at this combination and found nothing. We cannot rule an interaction out.

Feingold Diet is an eating pattern rather than something you take. Ask your pharmacist or doctor before changing how you eat while on a prescribed medicine: some medicines are dosed around meals, and a change in diet can change how they work. 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.

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 Feingold Diet

What is Feingold Diet?

  • Hyperactivity (ADHD) in children
  • Behavioral problems in kids
  • Attention and focus concerns
  • Childhood sleep and mood issues

The Feingold Diet is an elimination eating plan that removes certain artificial food colors, flavors, sweeteners, preservatives, and some natural salicylate-containing foods, mainly to reduce hyperactivity in children. Scientific evidence is mixed and limited, though a small number of children may be sensitive to specific food additives. If you try it, work with a pediatrician or registered dietitian so your child still gets balanced nutrition.

Elimination diet / structured eating plan

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

Feingold Diet: dosing

There is no pill or standardized "dose" for the Feingold Diet — it is a pattern of eating. It is typically done in phases: a stricter starting period that removes targeted additives and salicylate-rich foods, followed by gradual reintroduction to identify specific triggers.Because the diet can be complex and restrictive, it is best to follow program guidance and work with a registered dietitian or pediatrician to make sure your child's overall diet stays balanced.

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.
