Red Raspberry + Lamotrigine

Lamotrigine brand name: Lamictal.

No Known Interaction
Medically reviewed by · Updated July 2026 · Pair last verified Sep 13, 2026
The bottom line No known interaction

We found no known interaction between Red Raspberry 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. 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.

Interaction report

Red Raspberry 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 Red Raspberry 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.

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.

How we checked

Why No Interaction Is Listed for Lamotrigine

Interactions in our licensed database are recorded against drug classes, not just single drug names. Lamotrigine is filed under 5 classifications — including anticonvulsants, glucuronidated drugs, cns depressants. Red Raspberry has documented interactions with 2 drug classes — the most serious being anticoagulant/antiplatelet drugs (moderate) and insulin (moderate) — and none of Lamotrigine’s classifications are among them.

Classification data comes from our licensed Natural Medicines dataset. A medication can belong to classes beyond those recorded there, so this describes how the check was run — it is not a safety guarantee.

What to actually watch for

No Interaction Found — But Data Suggests Red Raspberry and Lamotrigine 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 taking both can make those effects more likely to turn up, and harder to pin on one or the other if they do.

  • Stomach upset / Diarrhea Additional detail

Special populations

Red Raspberry in Pregnancy & Breastfeeding

Pregnancy Likely Safe

When the fruit is used orally in amounts commonly found in foods.

Pregnancy Possibly Safe

When red raspberry leaf is used orally and appropriately in medicinal amounts during late pregnancy under the supervision of a healthcare provider. Red raspberry leaf is used by nurse midwives to facilitate delivery. There is some evidence that red raspberry leaf in doses of up to 2.4 grams daily, beginning at 32 weeks' gestation and continued until delivery, can be safely used for this purpose. Make sure patients do not use red raspberry leaf without the guidance of a healthcare professional.

Pregnancy Likely Unsafe

When red raspberry leaf is used orally in medicinal amounts throughout pregnancy or for self-treatment. Red raspberry leaf might have estrogenic effects. These effects can adversely affect pregnancy. Tell pregnant patients not to use red raspberry leaf at any time during pregnancy without the close supervision of a healthcare provider.

Lactation Likely Safe

When the fruit is used orally in amounts commonly found in foods. There is insufficient reliable information available about the safety of red raspberry leaf; avoid using.

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 Red Raspberry

What is Red Raspberry?

  • Pregnancy and labor support
  • Menstrual cramps
  • Digestive upset and diarrhea
  • Sore throat and mouth rinse
  • Antioxidant support

Red raspberry leaf is a traditional herbal remedy most often used as a tea in late pregnancy and for menstrual discomfort, but solid scientific evidence for these uses is limited. It is generally considered well tolerated by most adults, but pregnant people should talk with their doctor or midwife before using it.

Rubus idaeus · Rosaceae · Leaves and fruit · Tea, capsules, tablets, dried leaf, liquid extract

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

Red Raspberry: dosing

There is no official or standardized dose for red raspberry leaf. It is most commonly taken as a tea made from dried leaves, and also comes in capsules, tablets, and liquid extracts.Because products vary in strength, the best approach is to 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.

Taking Red Raspberry and Lamotrigine Together: Common Questions

Is it safe to take Red Raspberry with Lamotrigine?
We do not list a known interaction between Red Raspberry and Lamotrigine. 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 Red Raspberry and Lamotrigine 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.
How was the Red Raspberry and Lamotrigine combination checked?
Interactions in our licensed database are recorded against drug classes. Lamotrigine is filed under 5 classifications, and Red Raspberry has documented interactions with 2 drug classes — none of Lamotrigine's classifications are among them. A medication can belong to classes beyond those recorded in our dataset, so this describes how the check was run rather than guaranteeing safety.
Does Red Raspberry interact with any other medications?
Yes. Red Raspberry has 135 documented drug interactions in our database — Lamotrigine is simply not one of them. If you take anything else, it is worth checking each one; they are all listed on this page.
Does Lamotrigine interact with any supplements?
Yes. Lamotrigine has documented interactions with 116 supplements in our database — Red Raspberry is not one of them. The Lamotrigine interaction page linked on this page lists every one, ranked by severity.
