The bottom line No known interaction

We found no known interaction between Brown Rice and Lamotrigine 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.

Brown Rice and Lamotrigine

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 Lamotrigine and Brown Rice in our sources. This does not guarantee that the combination is completely free of risk — there is often limited research on supplements and herbal products, especially around drug interactions.

Worth understanding: our licensed dataset holds no drug-interaction record for Brown Rice at all — not against Lamotrigine, 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.

If you decide to take both, the practical routine is simple: add one new thing at a time and note the date you started it. If the combination is going to disagree with you, it usually shows in the first days to a couple of weeks — and a start date turns “I’ve been feeling off” into something a pharmacist can actually work with. 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.

This is not an interaction — none of it involves Brown Rice. These are the most notable effects listed in the ADVERSE REACTIONS section of Lamotrigine’s own FDA label, for the medication by itself.

  • Unsteadiness Worth acting on
  • Seizures Worth acting on
  • Chest pain Worth acting on
  • Low mood Worth acting on
  • A higher chance of infection Worth acting on
  • An allergic reaction Worth acting on
  • Changes to your period

Read the label on DailyMed › Brown Rice’s licensed record lists no adverse effects our clinical vocabulary could match, so there is no Brown Rice side to compare — that is a limit of the record, not a statement that Brown Rice has no side effects.

From our pharmacist’s overview on the Lamotrigine page

“Alcohol, ordinary beer or wine, sits at the top of the interaction list for lamotrigine (Lamictal), with well-documented added sedation, and it sets the tone for a list I would treat with real care. Of the 116 supplements and herbs on file, 78 have sedative effects of their own, so the biggest theme by far is stacked drowsiness and slo…”

About Brown Rice

What is Brown Rice?

  • General nutrition and fiber intake
  • Heart health support
  • Blood sugar management
  • Weight management
  • Digestive health

Brown rice is a whole grain that keeps its fiber-rich bran and nutrient-packed germ, making it more nutritious than white rice. As part of a balanced diet, it may support heart health, digestion, and steadier blood sugar, but it is a food rather than a treatment for any disease. It is safe for most people; the main concern is its natural arsenic content, so variety in your grains is wise.

Oryza sativa · Poaceae · Whole grain (bran, germ, and endosperm) · Whole cooked grain, flour, rice bran, rice bran oil, brown rice protein powder, capsules

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

Brown Rice: dosing

There is no medical "dose" for brown rice because it is a food. A standard serving is about a half to one cup of cooked rice, eaten as part of meals. Dietary guidelines suggest making at least half of your grains whole grains, and brown rice can count toward that goal.For brown rice supplements such as protein powder or rice bran oil, follow the directions on the product label.

About Lamotrigine

What Is Lamotrigine Used For?

Brand name: Lamictal

Lamotrigine is used to treat several types of seizures in adults and children aged 2 and older — including partial-onset seizures, generalized tonic-clonic (grand mal) seizures, and seizures related to Lennox-Gastaut syndrome. In older teens and adults, it can also be used alone (monotherapy) after transitioning off another seizure medicine.

For adults with bipolar I disorder, lamotrigine is used as a maintenance treatment — meaning it helps delay the return of mood episodes like depression, mania, or mixed states. It is not approved to treat an active manic or mixed episode that's happening right now.
