Feingold Diet and Telmisartan

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 Telmisartan 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 Telmisartan, 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.

Feingold Diet safety at a glance

Feingold Diet overall Use caution Generally low risk, but restrictive diets in children can lead to nutrition gaps if not supervised.
Pregnancy Use caution The diet is aimed at children; pregnant people should not follow restrictive diets without medical guidance.
Breastfeeding Use caution Restricting your own diet while breastfeeding is not recommended without a clinician's advice.

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

What Telmisartan’s Own FDA Label Lists

This is not an interaction — none of it involves Feingold Diet. These are the most notable effects listed in the ADVERSE REACTIONS section of Telmisartan’s own FDA label, for the medication by itself. Knowing the drug’s own list makes it easier to work out the likely cause if something new turns up while you follow Feingold Diet and take the medicine. 10 of them are worth acting on rather than waiting out — marked below.

  • Severe muscle breakdown Worth acting on
  • High potassium Worth acting on
  • Low sodium Worth acting on
  • Low blood sugar Worth acting on
  • High blood sugar Worth acting on
  • Fainting Worth acting on
  • Wheezing Worth acting on
  • Shortness of breath Worth acting on mentioned in 6.2% of FDA reports for Telmisartan
  • Chest pain Worth acting on
  • Low mood Worth acting on

From the ADVERSE REACTIONS section of the FDA label for Telmisartan. Read the label on DailyMed › Where a percentage is shown, it is the share of 19,596 voluntary FDA FAERS reports for Telmisartan that mention that effect — a reporting proportion, not an incidence rate and not evidence the drug caused it. Feingold Diet’s licensed record lists no adverse effects our clinical vocabulary could match, so there is no Feingold Diet side to compare — that is a limit of the record, not a statement that Feingold Diet has no side effects.

From our pharmacist’s overview on the Telmisartan page

“Telmisartan (Micardis) has one job, holding blood pressure in a safe range, and most of the 140 supplements and herbs listed here can either pile onto that effect or push against it, so I'd approach these combinations with real care. Four carry a major rating and deserve your attention first: two toxic plants that act directly on the h…”

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.
