HelloPharmacist Scorecard of Sinupret Kids Syrup Sinus & Immune by Bioforce

Our pharmacy team’s full take, with four database checks built into the cards below — a summary of what is known, not a grade of the product itself.

From our pharmacy team — supplement deep dive

Generated from HelloPharmacist’s pharmacist-curated databases and editorial rules · Last generated Jul 11, 2026

What’s inside

Low disclosure
Ingredient Transparency · database check
Low

Most active ingredients don't disclose an individual amount — you can't tell how much of each you're getting.

Why this rating?
  • The label discloses an exact amount for 0 of its 5 active ingredients.
  • “Sinupret(R) proprietary blend” is a proprietary blend — the label gives one combined amount (880 mg) without saying how much of each component you get.

This syrup contains five active herbal ingredients: gentian, European elder, cowslip, sorrel, and European vervain. Together they're formulated to support sinus and immune function in children.

The product also contains inactive ingredients including water, maltitol (a sweetener), ethyl alcohol, and cherry flavor to make it palatable for kids.

Does it work?

Moderate evidence
Evidence for Intended Use · database check
By FDA rules, dietary supplements can’t claim to treat, cure, or prevent disease — so labels speak in careful marketing language. We discern each product’s intended use from its name, label claims, and label statements, then grade the clinical evidence for that use. How these ratings are computed
Moderate

Some clinical evidence supports this product's ingredients for its stated purpose, but it isn't conclusive.

Why this rating?
  • The label markets this product for: Promotes nasal health and supports immune system.
  • We looked for evidence on: Rhinosinusitis, Sinusitis, Bronchitis, Sinus congestion, Upper respiratory support, Nasal congestion.
  • The strongest evidence on file: Cowslip is rated "Possibly Effective" for Sinusitis (Natural Medicines).
  • Also on file: Gentian is rated "Insufficient Reliable Evidence To Rate" for Rhinosinusitis.
  • Also on file: Sorrel is rated "Insufficient Reliable Evidence To Rate" for Bronchitis, Rhinosinusitis.

The evidence for these ingredients is limited. Cowslip is rated possibly effective for sinusitis, suggesting some traditional use and research backing — though the data aren't conclusive.

The other ingredients — gentian, European elder, sorrel, and European vervain — either haven't been studied enough for their effectiveness in sinus or immune support, or the evidence we hold is insufficient to rate them. This doesn't mean they don't work; it means we just don't have solid clinical proof in the data we review.

The evidence, ingredient by ingredient Gentian Cowslip Sorrel

How safe is it?

Well-documented data
Safety Information · database check
Well characterized

Adverse-effect, pregnancy, and general safety data are on file for most of these ingredients.

Why this rating?
  • We hold adverse-effect (side-effect) data for 2 of the 3 matched ingredients.
  • Pregnancy & breastfeeding safety ratings cover 3 of 3.
  • General safety write-ups exist for 3 of 3.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Gentian is generally well tolerated in small amounts, but it can upset your stomach and hasn't been studied at high doses. Some people using gentian in combination with other herbs have reported nausea, vomiting, diarrhea, and bloating.

Sorrel contains high levels of oxalates, which can be a concern at large or concentrated doses and may theoretically affect kidney function — though this is rare. Sorrel pollen can also trigger allergic reactions in people sensitive to weed pollen.

Cowslip is generally used in traditional teas, but human safety data are sparse and allergic reactions are possible. We have no reliable safety information for European Elder or European Vervain at this time.

Side effects, ingredient by ingredient Gentian Cowslip Sorrel

Meds to double-check

Moderate interaction found
Known Interaction Concern · database check
Moderate identified

The most serious documented interaction for these ingredients is Moderate. Check your medications for a personalized result.

Why this rating?
  • 2 of the 3 matched ingredients can interact with medications — Gentian, Sorrel.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: anticoagulant / antiplatelet drugs.
  • For scale: 333 individual medications appear in the full list. A big number alone doesn't make a product dangerous — what matters is whether YOUR medication is on it, so run yours through the interaction checker on this page.

Before giving this syrup to your child, double-check any blood thinners or antiplatelet medications (like aspirin or warfarin) — sorrel may add to their effect. If your child takes blood pressure medication, check that too, since gentian may increase how much it lowers pressure.

Also verify any antihistamines, especially fexofenadine (Allegra), as sorrel may reduce their absorption. For European Elder and European Vervain, we hold no interaction data, so we cannot advise on those.

The bottom line

Scorecard at a glanceFormula with limited ingredient disclosure with some supporting evidence for its stated purpose. Moderate medication interactions have been identified, and safety information is well characterized.

Sinupret Kids Syrup is a traditional herbal formula that may appeal to parents looking for plant-based sinus and immune support. If your child takes blood thinners, blood pressure medications, or antihistamines like fexofenadine, check with us or your pharmacist first — sorrel and gentian could affect how those drugs work.

Gentian1 drug type · 172 drugs

Antihypertensive Drugs

Theoretically, taking gentian with antihypertensive drugs might increase the risk of hypotension.
In vitro research shows that gentian can cause vasodilation and lower blood pressure.

Likelihood Possible Evidence D
Gentian full monograph & interactions

Sorrel3 drug types · 169 drugs

Anticoagulant/Antiplatelet Drugs

Theoretically, sorrel might cause additive effects and side effects when used with anticoagulant or antiplatelet drugs.
In vitro, sorrel has been shown to inhibit platelet aggregation. However, this effect has not been reported in humans.

Likelihood Possible Evidence D
Fexofenadine (Allegra)

Sorrel might reduce the effectiveness of fexofenadine by reducing its absorption from the gut.
In vitro research shows that an ethanol extract of sorrel inhibits organic anion-transporting polypeptide 1A2 (OATP1A2), which transports fexofenadine from the intestine into cells. In rats, concomitant administration of sorrel extract with fexofenadine reduces oral absorption of fexofenadine and the area under the plasma concentration-time curve (AUC).

Likelihood Likely Evidence D
Organic Anion-Transporting Polypeptide Substrates (Oatp)

Sorrel might reduce the effectiveness of OATP substrates by reducing their absorption from the gut.
In vitro research shows that sorrel inhibits OATP1A2. Theoretically it may inhibit other OATPs. The OATPs are expressed in the small intestine and liver and transport drugs into cells. Inhibition of OATP may reduce the bioavailability of oral drugs that are substrates of OATP.

Sinupret Kids Syrup Sinus & Immune by Bioforce: Common Questions

Does Sinupret Kids Syrup Sinus & Immune by Bioforce interact with any medications?
Yes. Based on its ingredients, Sinupret Kids Syrup Sinus & Immune has a known interaction with 333 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Sinupret Kids Syrup Sinus & Immune contains 5 active ingredients, and an interaction can come from any of them. We check every ingredient, combine the results into one list per medication, and show which ingredient and mechanism is responsible.
Where does this information come from?
The product label data comes from the NIH Dietary Supplement Label Database (DSLD); the interaction data is built on the Natural Medicines database and reviewed by HelloPharmacist pharmacists.
Is this safe for my child if she's pregnant or breastfeeding?
This product is labeled for kids, so pregnancy isn't the main concern — but if a breastfeeding parent were to take it, gentian and cowslip should be avoided due to insufficient safety data. Sorrel is rated possibly safe during breastfeeding, but concentrated medicinal doses haven't been proven safe, so it's best to avoid it. Talk with your pediatrician or pharmacist about what's right for your situation.
What does cowslip do in this formula?
Cowslip is included for its possible effectiveness in sinusitis. It's traditionally been used in herbal preparations for sinus support, though the solid clinical evidence is limited. It's one of the better-studied ingredients in this blend.
Can this syrup upset my child's stomach?
It's possible. Gentian can cause gastrointestinal upset in some children, and people using gentian with other herbs have reported nausea, vomiting, diarrhea, and bloating. Sorrel has also been linked to nausea and an unpleasant aftertaste when used with other herbs. If your child develops stomach discomfort, stop the product and call your pharmacist.
Will this work for my child's sinus infection?
Cowslip is rated possibly effective for sinusitis, meaning there's some research and traditional use backing it — but the evidence isn't strong or complete. The other ingredients haven't been studied enough to know how well they work for sinus problems. This product may help, but it's not guaranteed, and it shouldn't replace medical treatment if your child's infection is severe.
Does this syrup contain any allergens I should know about?
Sorrel pollen can trigger allergic reactions in people sensitive to weed pollen — up to 19% of people with weed allergies may react. Cowslip can also cause allergic reactions in some people. If your child has known weed or plant allergies, mention those to your pharmacist before starting this product.
