Sour Cherry + Interferon Beta-1a
Interferon Beta-1a brand names: Rebif, Avonex.
We found no known interaction between Sour Cherry 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.
Sour Cherry 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 Sour Cherry 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 Sour Cherry 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.

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 Sour Cherry
What is Sour Cherry?
- Muscle soreness after exercise
- Gout and joint discomfort
- Sleep support
- Arthritis pain
- General antioxidant support
Sour cherry (often sold as tart cherry or Montmorency cherry) is a fruit-based supplement rich in antioxidants that people use for muscle recovery, joint and gout symptoms, and sleep. Early research is promising but limited, so it is not a proven treatment. It is generally well tolerated as a food, but talk to your pharmacist or doctor before using concentrated products.
Prunus cerasus · Rosaceae · Fruit (and fruit juice or concentrate) · Juice, concentrate, capsules, powder, dried fruit, extract

Sour Cherry: dosing
There is no official or standardized dose for sour cherry supplements. Studies have used different forms and amounts, including juice, concentrate, and capsules, so there is no single agreed-upon dose.The best approach is to follow the directions on the product label and not exceed them.
