The bottom line No known interaction

We found no known interaction between Lingonberry and Interferon Beta-1a 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.

Interaction report

Lingonberry and Interferon Beta-1a

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 Interferon Beta-1a and Lingonberry 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 Lingonberry at all — not against Interferon Beta-1a, 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

What Lingonberry Itself Has Been Linked To

This is not an interaction — nothing below involves Interferon Beta-1a. It is the side-effect record for Lingonberry on its own, from the licensed Natural Medicines monograph. If something new turns up after you add Lingonberry, this list is the first place to look.

Vomiting / Nausea Additional detail
“Orally, lingonberry seems to be well tolerated. It may cause nausea and vomiting in some patients due to its high tannin content (18).”

Everything above comes from the Natural Medicines adverse-effect record for Lingonberry — expand a row for the licensed statement it rests on. We haven’t matched Interferon Beta-1a to its FDA label in our system yet, so we can’t compare its own side-effect list here — the leaflet that comes with your prescription is the authoritative list for Interferon Beta-1a.

From our pharmacist’s overview on the Interferon Beta-1a page

“Siberian cocklebur, an herb tied to documented cases of liver failure, is the first name to know for anyone injecting interferon beta-1a (Rebif, Avonex) for multiple sclerosis. Interferon beta-1a can strain the liver on its own, which is why prescribers order routine liver blood tests, and 38 of the 57 supplements on file carry that sa…”

About Lingonberry

What is Lingonberry?

Urinary tract health
Antioxidant support
Heart and metabolic health
Inflammation

Lingonberry is a tart red berry rich in antioxidants such as anthocyanins and the compound arbutin, and it is popular as a food and folk remedy for urinary tract and general wellness. Human evidence for specific health benefits is still limited, so it is best enjoyed as part of a healthy diet rather than relied on to treat any condition. Talk to your pharmacist or doctor before using concentrated extracts, especially if you are pregnant, breastfeeding, or have a medical condition.

Vaccinium vitis-idaea · Ericaceae · Berries and leaves · Juice, dried berries, jam, capsules, extracts, tea (from leaves)

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

Lingonberry: dosing

There is no official or standardized dose for lingonberry supplements. The amount of active compounds can vary widely between products such as juices, dried berries, capsules, and extracts.If you choose to use a lingonberry product, follow the directions on the product label and do not exceed the recommended amount. Eating the berries as food is a simple and generally safe way to enjoy them.

About Interferon Beta-1a Intramuscular Injection

What Is Interferon Beta-1a Intramuscular Injection Used For?

Brand names: Rebif, Avonex

Interferon beta-1a intramuscular injection is used to treat adults with various forms of multiple sclerosis (MS; a disease in which the nerves do not function properly and people may experience weakness, numbness, loss of muscle coordination, and problems with vision, speech, and bladder control) including:
- clinically isolated syndrome (CIS; nerve symptom episodes that last at least 24 hours),
- relapsing-remitting forms (course of disease where symptoms flare up from time to time), or
- secondary progressive forms (course of disease where relapses occur more often).
Interferon beta-1a is in a class of medications called immunomodulators. It works by decreasing inflammation and preventing nerve damage that may cause symptoms of multiple sclerosis.

Most-Reported Side Effects for Interferon Beta-1a

From FAERS, the FDA’s public side-effect reporting system (192,069 reports, all brands). Reports are voluntary and are not proof the drug caused the effect.
