HelloPharmacist Scorecard of Cough Syrup + Immune Natural Grape Flavor by Zarbee's Baby

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

What’s inside

Full disclosure
Ingredient Transparency · database check
Full

Every active ingredient lists its own amount on the label.

Why this rating?
  • The label discloses an exact amount for 2 of its 2 active ingredients.
  • No proprietary blends here — you can verify the dose of every single component.

This product contains 2 active ingredients: zinc and honey. Zinc is a mineral your body needs for immune function and wound healing, and it's included to support immune health during cough and cold symptoms.

Honey has been used traditionally to soothe coughs and throat irritation. The syrup also contains water, natural flavor, and citric acid as inactive ingredients.

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: Soothes coughs, hoarseness, dry throat irritants.
  • We looked for evidence on: Cough, Sore throat, Hoarseness, Throat irritation.
  • The strongest evidence on file: Honey is rated "Possibly Effective" for Cough (Natural Medicines).
  • Also on file: Zinc is rated "Insufficient Reliable Evidence To Rate" for Postoperative sore throat.

The evidence behind these ingredients is mixed. Zinc is effective for treating zinc deficiency and likely effective for Wilson disease, but for supporting immune health during a cough, the data shows it's only possibly effective for general immune support—the evidence isn't strong.

Honey is possibly effective at soothing coughs and throat irritation. Neither ingredient has strong proof for preventing or shortening colds or coughs in otherwise healthy children.

The evidence, ingredient by ingredient Zinc Honey

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 2 matched ingredients.
  • Pregnancy & breastfeeding safety ratings cover 2 of 2.
  • General safety write-ups exist for 2 of 2.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Zinc is generally well tolerated in recommended amounts. The main side effects are nausea, vomiting, diarrhea, abdominal cramps, and a metallic taste—these are dose-related, meaning higher doses are more likely to cause them.

Doses above 40 mg daily for adults can raise the risk of copper deficiency over time. Honey is safe for children over 1 year of age and generally well tolerated; nausea, stomach pain, and vomiting can occur but are uncommon.

Avoid honey from the Black Sea coast of Turkey, as some batches contain toxins that can cause heart rhythm problems. Allergic reactions to honey are rare but possible.

For pregnancy and breastfeeding: we hold conflicting data on zinc (one entry says Likely Safe, another says Likely Unsafe), so talk to your obstetrician or midwife for personalized advice. Honey is rated Likely Safe in pregnancy and for a breastfeeding mother to consume, though medicinal use should be discussed with your provider.

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

Why this rating?
  • 2 of the 2 matched ingredients can interact with medications — Honey, Zinc.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: anticoagulant / antiplatelet drugs.
  • For scale: 788 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, tell your pediatrician or pharmacist if your child takes any quinolone antibiotics (like ciprofloxacin), cephalexin, tetracycline antibiotics, penicillamine, ritonavir, integrase inhibitors for HIV, or bictegravir/emtricitabine/tenofovir alafenamide—zinc can reduce how well these work and may require dose timing changes. Less certain risks involve phenytoin (Dilantin), some drugs broken down by the liver enzyme CYP3A4, and blood thinners or antiplatelet drugs, where honey's effects are theoretical or mixed.

Check the exact medications your child takes with your healthcare provider.

The bottom line

Scorecard at a glanceFully disclosed formula with some supporting evidence for its stated purpose. Moderate medication interactions have been identified, and safety information is well characterized.

This syrup may help soothe your child's cough and support immune health, but the evidence for those uses isn't strong. The main concern is zinc's interaction with certain antibiotics and other medications—if your child takes any prescription drugs, check them against the medication list on this page before giving the syrup.

Talk it over with your pediatrician or pharmacist to be sure it's right for your child.

Each ingredient & the kinds of drugs it affects

For each ingredient in Cough Syrup + Immune Natural Grape Flavor with known interactions, here are the types of medications they can affect. Open any type for the detail — or search your exact drug in the checker above.

Honey3 drug types · 738 drugs

Phenytoin (Dilantin)

Theoretically, honey might increase levels of phenytoin.
In an animal model, the rate and extent of absorption of phenytoin was increased by honey. This effect has not been reported in humans.

Likelihood Possible Evidence D
Anticoagulant/Antiplatelet Drugs

Theoretically, honey may increase the risk of bleeding when used with anticoagulant or antiplatelet drugs.
In vitro, honey inhibits platelet aggregation and increases the time to clotting. Furthermore, animal research suggests that feeding mice large doses of honey for 12 days increases bleeding time when compared with no intervention. However, these effects have not been reported in humans.

Likelihood Unlikely Evidence D
Cytochrome P450 3A4 (Cyp3A4) Substrates

Theoretically, honey might decrease levels of drugs metabolized by CYP3A4, but research is conflicting.
Some clinical research shows that honey induces CYP3A4. However, other clinical studies found no effect on CYP3A4 activity. Different honey preparations may have different effects on CYP3A4.

Likelihood Possible Evidence B

Zinc10 drug types · 67 drugs

Bictegravir/Emtricitabine/Tenofovir Alafenamide (Biktarvy)

Theoretically, zinc might decrease levels of bictegravir/emtricitabine/tenofovir alafenamide by reducing its absorption.
Advise patients that bictegravir/emtricitabine/tenofovir alafenamide should be taken at least 2 hours before or 6 hours after zinc containing products.

Likelihood Probable Evidence D
Cephalexin (Keflex)

Zinc might decrease cephalexin levels by chelating with cephalexin in the gut and preventing its absorption.
A pharmacokinetic study shows that zinc sulfate 250 mg taken concomitantly with cephalexin 500 mg decreases peak levels of cephalexin by 31% and reduces the exposure to cephalexin by 27%. Also, taking zinc sulfate 3 hours before cephalexin decreases peak levels of cephalexin by 11% and reduces the exposure to cephalexin by 18%. By decreasing cephalexin levels, zinc might increase the risk of treatment failure. This effect does not occur when zinc is taken 3 hours after the cephalexin dose. To avoid an interaction, advise patients take zinc sulfate 3 hours after taking cephalexin.

Likelihood Probable Evidence B
Cisplatin (Platinol-Aq)

Theoretically, zinc might interfere with the therapeutic effects of cisplatin.
Animal research suggests that zinc stimulates tumor cell production of the protein metallothionein, which binds and inactivates cisplatin. It is not known whether zinc supplements or high dietary zinc intake can cause clinically significant interference with cisplatin therapy. Cisplatin might also increase zinc excretion.

Likelihood Possible Evidence D
Integrase Inhibitors

Theoretically, taking zinc along with integrase inhibitors might decrease the levels and clinical effects of these drugs.
Zinc is a divalent cation. Pharmacokinetic studies have shown that other divalent cations such as calcium and iron can decrease blood levels of the integrase inhibitor dolutegravir through chelation.

Likelihood Possible Evidence D
Penicillamine (Cuprimine, Depen)

Zinc might reduce the levels and clinical effects of penicillamine.
By forming an insoluble complex with penicillamine, zinc interferes with penicillamine absorption and activity. Zinc supplements reduce the efficacy of low-dose penicillamine (0.5-1 gram/day), but do not seem to affect higher doses (1-2.75 gram/day), provided dosing times are separated. Advise patients to take zinc and penicillamine at least 2 hours apart.

Likelihood Probable Evidence B
Quinolone Antibiotics

Zinc can decrease the levels and clinical effects of quinolones antibiotics.
Quinolones form complexes with zinc in the gastrointestinal tract, reducing absorption of both the quinolone and zinc if taken at the same time. Advise patients to take these drugs at least 2 hours before, or 4-6 hours after, zinc supplements.

Likelihood Probable Evidence B
Ritonavir (Norvir)

Zinc modestly reduces levels of ritonavir.
Clinical research shows that zinc might reduce serum ritonavir levels by chelating with ritonavir in the gut and preventing its absorption. In patients with HIV, ritonavir is taken with atazanavir to prevent the metabolism and increase the effects of atazanavir. A pharmacokinetic study shows that, in patients being treated with atazanavir/ritonavir, co-administration of zinc sulfate (Solvazinc tablets) 125 mg as a single dose or as multiple daily doses for 2 weeks reduces plasma levels of ritonavir by about 16%. However, atazanavir levels still remains high enough to prevent HIV virus replication. Therefore, the decrease in ritonavir levels is not likely to be clinically significant.

Likelihood Probable Evidence B
Tetracycline Antibiotics

Zinc might reduce levels of tetracycline antibiotics.
Tetracyclines form complexes with zinc in the gastrointestinal tract, which can reduce absorption of both the tetracycline and zinc when taken at the same time. Taking zinc sulfate 200 mg with tetracycline reduces absorption of the antibiotic by 30% to 40%. Demeclocycline and minocycline cause a similar interaction. However, doxycycline does not seem to interact significantly with zinc. Advise patients to take tetracyclines at least 2 hours before, or 4-6 hours after, zinc supplements to avoid any interactions.

Likelihood Probable Evidence B
Amiloride (Midamor)

Amiloride can modestly reduce zinc excretion and increase zinc levels.
Clinical research shows that amiloride can reduce urinary zinc excretion, especially at doses of 10 mg per day or more. This zinc-sparing effect can help to counteract zinc losses caused by thiazide diuretics, but it is unlikely to cause zinc toxicity at usual amiloride doses. The other potassium-sparing diuretics, spironolactone (Aldactone) and triamterene (Dyrenium), do not seem to have a zinc-sparing effect.

Likelihood Probable Evidence B
Atazanavir (Reyataz)

Zinc modestly reduces levels of atazanavir, although this effect does not seem to be clinically significant.
Clinical research shows that zinc might decrease serum atazanavir levels by chelating with atazanavir in the gut and preventing its absorption. Although a single dose of zinc sulfate (Solvazinc tablets) 125 mg orally does not affect atazanavir concentrations in patients being treated with atazanavir/ritonavir, co-administration of zinc sulfate 125 mg daily for 2 weeks reduces plasma levels of atazanavir by about 22% in these patients. However, despite this decrease, atazanavir levels still remain at high enough concentrations for the prevention of HIV virus replication.

Cough Syrup + Immune Natural Grape Flavor by Zarbee's Baby: Common Questions

Does Cough Syrup + Immune Natural Grape Flavor by Zarbee's Baby interact with any medications?
Yes. Based on its ingredients, Cough Syrup + Immune Natural Grape Flavor has a known interaction with 787 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Cough Syrup + Immune Natural Grape Flavor contains 2 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.
Can I give this to my baby under 1 year old?
The product facts don't specify an age limit, but honey itself is not recommended for babies under 1 year. Talk to your pediatrician about whether this syrup is appropriate for your baby's age.
What are the side effects of zinc in this syrup?
The most common are nausea, vomiting, diarrhea, stomach cramps, and a metallic taste. These are usually dose-related—higher doses are more likely to cause them. At recommended levels, zinc is well tolerated.
Will this syrup prevent my child from catching a cold?
The evidence that zinc prevents colds or shortens them in healthy children is only possibly effective, meaning it's not well established. Honey may help soothe a cough once it starts, but again, the proof is only possibly effective.
Is it safe to give this while my child is on antibiotics?
Zinc can interfere with how some antibiotics are absorbed, making them less effective. If your child is on any antibiotic, check the specific drug name with your pediatrician or pharmacist before giving this syrup—they may need to space the doses apart.
Can I use this syrup if my child is allergic to bee products?
This syrup contains honey, which is made by bees. Allergic reactions to honey are rare but possible, especially in people with existing allergies to bee products. Talk to your pediatrician if your child has any known bee allergies before using it.
