Drug & supplement interaction

Raw Food Diet + Phenytoin

Phenytoin brand names: Dilantin Kapseals, Dilantin, Di-Phen, Dilantin Infatabs, Phenytek, and others.

No Known Interaction
Medically reviewed by · Updated July 2026 · Pair last verified Sep 27, 2026
The bottom line No known interaction

We found no known interaction between Raw Food Diet and Phenytoin 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. Additionally, although there is no interaction, the two are separately associated with some of the same side effects, which would make a new symptom harder to attribute to one or the other.

Raw Food Diet and Phenytoin

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

Worth understanding: our licensed dataset holds no drug-interaction record for Raw Food Diet at all — not against Phenytoin, 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.

Raw Food 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.

What to actually watch for

No Interaction Found — But Data Suggests Raw Food Diet and Phenytoin May Share Several of the Same Side Effects

This is not an interaction. Neither one changes how your body handles the other, and nothing here says they react together. What our sources do show is that each has separately been linked to the effects below — so following Raw Food Diet while taking the medicine can make those effects more likely to turn up, and harder to pin on one or the other if they do.

  • Vomiting / Nausea Additional detail

    Raw Food Diet

    “In one clinical study, patients following a 40% raw food diet reported nausea, vomiting, and malaise after consuming typical restaurant and banquet foods. Participants also reported gastrointestinal symptoms when consuming certain foods, such as citrus fruit, nuts, and tomatoes.”

From our pharmacist’s overview on the Phenytoin page

“Phenytoin (Dilantin) is a seizure medicine with a narrow therapeutic index, meaning small changes in its blood level can bring seizures back or tip over into toxicity, so I treat its supplement list with real seriousness. The biggest group, 78 ingredients, piles on sedation, and alcohol, kava, and GHB all rate major for exactly that re…”

Eating pattern

About Raw Food Diet

What is Raw Food Diet?

  • Weight loss
  • Improving digestion
  • Increasing fruit and vegetable intake
  • General wellness and detox
  • Lowering cholesterol

A raw food diet emphasizes uncooked, unprocessed plant foods (and sometimes raw animal products) based on the idea that cooking destroys nutrients and enzymes. It can boost intake of fruits and vegetables and help with weight loss, but it carries real risks of nutrient deficiencies and foodborne illness. Talk with a doctor or dietitian before trying it, especially if you are pregnant, breastfeeding, or have a health condition.

Whole eating pattern based on uncooked or minimally heated plant foods, fruits, vegetables, nuts, seeds, and sprouted grains

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

Raw Food Diet: dosing

Because a raw food diet is an eating pattern and not a pill, there is no standardized 'dose.' Plans vary widely—some people eat 100% raw, while others aim for 75% or 50% raw and cook the rest.If you want to try it, a safer approach is to add more raw fruits and vegetables to your meals rather than switching to fully raw all at once. Working with a registered dietitian helps you plan for protein, vitamin B12, vitamin D, calcium, iron, and omega-3 fats, and may include supplements to fill gaps.

About Phenytoin

What Is Phenytoin Used For?

Brand names: Dilantin Kapseals, Dilantin, Di-Phen, Dilantin Infatabs, Phenytek, Dilantin injection

Phenytoin is used to treat and prevent seizures. The specific types covered depend on the formulation. Oral extended-release capsules (including Phenytek), chewable tablets (including Dilantin Infatabs and Phenytoin Infatabs), and oral suspension (including Dilantin-125) are used for tonic-clonic (grand mal) and psychomotor (temporal lobe) seizures; most oral forms also cover prevention and treatment of seizures occurring during or after neurosurgery. Chewable tablets and some capsule formulations also cover complex partial seizures.

Parenteral (injectable) phenytoin sodium is used for generalized tonic-clonic status epilepticus (a prolonged, life-threatening seizure emergency) and for prevention and treatment of seizures during neurosurgery. The IV form can also substitute short-term for oral phenytoin when a patient cannot take it by mouth.

Most-Reported Side Effects for Phenytoin

From FAERS, the FDA’s public side-effect reporting system (40,278 reports, all brands). Reports are voluntary and are not proof the drug caused the effect.

Convulsion 3,522 reports
Seizure 3,095 reports
Toxicity to various agents 1,888 reports

Following Raw Food Diet While Taking Phenytoin: Common Questions

Is it safe to follow Raw Food Diet while taking Phenytoin?
We do not list a known interaction between Raw Food Diet and Phenytoin. That does not guarantee the combination is risk-free, so confirm with your pharmacist or doctor — especially if you take other medications or have a health condition.
Do Raw Food Diet and Phenytoin have any of the same side effects?
Yes — our sources link each of them separately to 2 of the same effects. That is not an interaction: neither changes how your body handles the other. It does mean that if one of those effects turns up, it can be harder to tell which one is behind it. They are listed on this page with the source behind each.
Does Phenytoin interact with any supplements?
Yes. Phenytoin has documented interactions with 224 supplements in our database — Raw Food Diet is not one of them. The Phenytoin interaction page linked on this page lists every one, ranked by severity.
