Drug & supplement interaction

Blue Flag + Romosozumab-Aqqg

Romosozumab-Aqqg brand name: Evenity.

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 Blue Flag and Romosozumab-Aqqg 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 label for Romosozumab-Aqqg states a food rule worth keeping to, and 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

Blue Flag and Romosozumab-Aqqg

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 Romosozumab-Aqqg and Blue Flag 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.

What to actually watch for

No Interaction Found — But Data Suggests Blue Flag and Romosozumab-Aqqg May Share a Side Effect

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.

  • Headache Additional detail

    Blue Flag

    “Orally, blue flag can cause nausea and vomiting, and the fresh root can irritate mucosa (4,19). Orally and topically, the volatile oil constituent of blue flag irritates mucous membranes and can cause lacrimation, eye inflammation, irritation of the throat, and headache (4).”

How to take them

Some Romosozumab-Aqqg Products Have a Food Rule — Blue Flag Should Not Break It

At least one FDA label for a product containing Romosozumab-Aqqg says to take it on an empty stomach. Most supplements — Blue Flag included — are taken with a meal, so the easy mistake is swallowing both together at breakfast. Where that rule applies, keep Romosozumab-Aqqg on its own and move Blue Flag to a meal later in the day.

This may not be true of your version. Food instructions belong to the product, not the ingredient: two Romosozumab-Aqqg products can carry different directions, and extended-release forms often differ from immediate-release ones. The label we read is quoted below — check the directions on your own box or bottle, or ask your pharmacist, for how to take the exact product you were given.

Allow EVENITY to sit at room temperature for at least 30 minutes before injecting.

From the Dosage and Administration section of the FDA label we read for Romosozumab-Aqqg — where that label names a specific product, the instruction is that product's. Read the label on DailyMed ›

A food rule is not an interaction — it is about how much of the medicine you absorb. The directions that came with your own product, and your pharmacist, outrank anything on this page.

About Blue Flag

What is Blue Flag?

  • Skin conditions like acne and eczema
  • Constipation and digestive complaints
  • Liver and gallbladder support (traditional)
  • Lymphatic and 'detox' tonic (traditional)
  • Thyroid and glandular swelling (traditional)

Blue Flag is a flowering plant whose root has been used in traditional and herbal medicine for skin and digestive complaints, but there is very little modern scientific evidence to support these uses. The fresh root can be toxic and irritating, so it should be used cautiously, if at all, and avoided in pregnancy and breastfeeding. Talk to a pharmacist or doctor before trying it.

Iris versicolor · Iridaceae · Dried rhizome (root) · Dried root, tincture, liquid extract, capsules, occasionally in topical preparations

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

Blue Flag: dosing

There is no well-established or standardized dose for Blue Flag, and reliable dosing information from quality clinical research is lacking. Traditional sources used small amounts of the dried root or tincture, but these are not validated by modern studies.If a product is used, follow the directions on the label and start low.

About Romosozumab-aqqg Injection

What Is Romosozumab-aqqg Injection Used For?

Brand name: Evenity

Evenity (romosozumab-aqqg) is approved to treat osteoporosis in postmenopausal women who are at high risk for breaking a bone. That includes women who have already had an osteoporotic fracture, have multiple risk factors for fractures, or have not responded to — or cannot tolerate — other osteoporosis treatments.

Treatment with Evenity is limited to 12 monthly doses. If continued bone protection is needed after that course, a prescriber will typically recommend switching to a different type of osteoporosis medication called an anti-resorptive agent.

Taking Blue Flag and Romosozumab-Aqqg Together: Common Questions

Is it safe to take Blue Flag with Romosozumab-Aqqg?
We do not list a known interaction between Blue Flag and Romosozumab-Aqqg. 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 Blue Flag and Romosozumab-Aqqg have any of the same side effects?
Yes — our sources link each of them separately to one 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.
Should I take Blue Flag and Romosozumab-Aqqg at the same time of day?
At least one FDA label for a product containing Romosozumab-Aqqg says to take it on an empty stomach, and supplements are usually taken with a meal — so taking them together at breakfast is the easy mistake. Where that applies, keep Romosozumab-Aqqg on its own and move Blue Flag to a meal later in the day. Food instructions belong to the product rather than the ingredient, so check the directions on your own box. This is about absorption, not an interaction.
Does Blue Flag interact with any other medications?
Yes. Blue Flag has 78 documented drug interactions in our database — Romosozumab-Aqqg is simply not one of them. If you take anything else, it is worth checking each one; they are all listed on this page.
