Interaction report

7,8-benzoflavone and Valbenazine Tosylate

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 Valbenazine Tosylate and 7,8-benzoflavone 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 7,8-benzoflavone at all — not against Valbenazine Tosylate, 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 Valbenazine Tosylate’s Own FDA Label Lists

This is not an interaction — none of it involves 7,8-benzoflavone.

Knowing the drug’s own list makes it easier to work out the likely cause if something new turns up while you take both. 9 of them are worth acting on rather than waiting out — marked below.

  • Thoughts of self-harm Worth acting on
  • Trouble passing urine Worth acting on
  • Unsteadiness Worth acting on
  • High blood sugar Worth acting on

From the ADVERSE REACTIONS section of the FDA label for Valbenazine Tosylate. Read the label on DailyMed › Where a percentage is shown, it is the share of 24,614 voluntary FDA FAERS reports for Valbenazine Tosylate that mention that effect — a reporting proportion, not an incidence rate and not evidence the drug caused it. 7,8-benzoflavone’s licensed record lists no adverse effects our clinical vocabulary could match, so there is no 7,8-benzoflavone side to compare — that is a limit of the record, not a statement that 7,8-benzoflavone has no side effects.

About 7,8-benzoflavone

What is 7,8-benzoflavone?

  • Lowering estrogen levels
  • Raising testosterone
  • Reducing gynecomastia from anabolic steroids
  • Bodybuilding and athletic performance

7,8-Benzoflavone (alpha-naphthoflavone) is a synthetic flavone studied mainly in laboratories for its effects on enzymes like aromatase and certain liver enzymes. It is not an approved or well-studied dietary supplement in humans, its safety is poorly defined, and aromatase inhibitors are banned in sports — so it should not be used without medical supervision.

Synthetic flavone compound (also studied as a plant flavonoid derivative) · Research chemical; sometimes found in bodybuilding or 'aromatase inhibitor' supplements

An interaction check asks whether these two react with each other — it does not ask whether 7,8-benzoflavone is a good idea for someone in your situation. Here is what our 7,8-benzoflavone record says about it on its own.
