Feingold Diet + Simeprevir Sodium
Simeprevir Sodium brand name: Olysio.
We found no known interaction between Feingold Diet and Simeprevir Sodium in our sources. Absence of a documented interaction is not the same as proven safety, and does not guarantee one does not exist. Do not start, stop, or change a medication or supplement based on this page; confirm with your pharmacist or doctor first.
Feingold Diet and Simeprevir Sodium
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 Simeprevir Sodium 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 Simeprevir Sodium, 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 Simeprevir Sodium page
“Hepatitis C treatment with simeprevir (Olysio) runs for months, and steady drug levels decide whether the virus gets cleared, so the 160 supplements on this page deserve real scrutiny. Only three carry a major rating, but they are common ones: grapefruit and St.”

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.
