Drug & supplement interaction

Bog Bilberry + Lioresal

Lioresal brand name: Lioresal Injection.

No Known Interaction
Medically reviewed by · Updated July 2026 · Pair last verified Oct 4, 2026
The bottom line No known interaction

We found no known interaction between Bog Bilberry and Lioresal 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.

Bog Bilberry and Lioresal

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 Lioresal and Bog Bilberry 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 Bog Bilberry at all — not against Lioresal, 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.

What to actually watch for

No Interaction Found — But Data Suggests Bog Bilberry and Lioresal 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.

  • Vomiting / Nausea Additional detail

    Bog Bilberry

    “Orally, poisonings from the ingestion of large quantities of the bog bilberry fruit are rare and were thought to be due to contamination with a fungus, Sclerroyina megalospora, that sometimes grows on bog bilberry (18). The symptoms of poisoning include queasiness and vomiting (18).”

See Every Supplement That Interacts With Lioresal

This page covers Bog Bilberry only. If you take other supplements — a multivitamin, a sleep aid, something for joints — the Lioresal page lists 10 supplements it has a documented interaction with, worst first, each one explained.

The most serious there right now: Procaine (major), Biofeedback (moderate), Dendrobium (moderate), Ginkgo (moderate) and Lithium (moderate).

By severity: 1 major · 9 moderate.

From our pharmacist’s overview on the Lioresal page

“Lioresal is baclofen, a muscle relaxant prescribed for spasticity, and I would treat its supplement list with genuine care. Of the ten ingredients on file, six, including everyday picks like melatonin and ginkgo, may lower the seizure threshold, an added worry with a drug whose abrupt changes can already provoke seizures.”

About Bog Bilberry

What is Bog Bilberry?

  • Antioxidant support
  • Eye and vision health
  • Circulation and blood vessel health
  • General wellness
  • Anti-inflammatory support

Bog bilberry is a wild blueberry-relative rich in antioxidant pigments called anthocyanins, and people use it much like its better-known cousin, the European bilberry. As a food it is generally safe, but there is little high-quality human research showing it treats any specific health condition. Talk with your pharmacist or doctor before using concentrated supplements, especially during pregnancy or breastfeeding.

Vaccinium uliginosum · Ericaceae · Berries (fruit); sometimes leaves · Fresh or dried berries, juice, jams, extracts, capsules, teas

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

Bog Bilberry: dosing

There is no established standard dose for bog bilberry as a supplement. As a food, you can simply enjoy the berries the way you would blueberries.If you choose a supplement, follow the directions on the product label and do not exceed the recommended amount.

About Baclofen

What Is Baclofen Used For?

Brand name: Lioresal Injection

Baclofen treats spasticity, which means stiff, tight muscles with spasms. Oral baclofen (tablets, Baclofen oral solution, Ozobax, Baclofen oral suspension, Fleqsuvy, Lyvispah) is used for spasticity from multiple sclerosis, especially flexor spasms with pain, clonus (rhythmic jerking) and muscle rigidity. It may also help some people with spinal cord injuries and other spinal cord diseases.

Intrathecal baclofen (Gablofen, Lioresal Intrathecal and other baclofen injections) is used for severe spasticity. It is given into the fluid around the spinal cord, usually through an implanted pump. It is not for skeletal muscle spasm from rheumatic disorders, and baclofen tablets are not recommended for stroke, cerebral palsy or Parkinson’s disease.

Is it safe to take Bog Bilberry with Lioresal?

Do Bog Bilberry and Lioresal 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.

Does Lioresal interact with any supplements?
Yes. Lioresal has documented interactions with 10 supplements in our database — Bog Bilberry is not one of them. The Lioresal interaction page linked on this page lists every one, ranked by severity.
