HelloPharmacist Scorecard of Immune Alert by Herbs Etc.
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.
What’s inside
Low disclosure
Immune Alert contains 11 ingredients, including active herbal extracts and a proprietary blend. The main active ingredients are andrographis herb extract, olive leaf extract, four different echinacea extracts (purpurea and angustifolia, in seed, root, and flower forms), elderberry extract, and spilanthes herb extract.
These are combined with inactive ingredients — gelatin capsule, glycerin, water, carob, chlorophyll, olive oil, sunflower lecithin, and beeswax — that serve as fillers and binders. The product blends traditional immune-support herbs, though the proprietary extract blend means you won't see exact individual amounts on the label.
Does it work?
Moderate evidence
Evidence for most of these ingredients' effectiveness is limited or not established in the data we hold. Andrographis shows possibly effective evidence for ulcerative colitis, tonsillopharyngitis, and osteoarthritis — but family Mediterranean fever lacks reliable evidence to rate.
Echinacea's effectiveness for anxiety, athletic performance, ADHD, burns, chronic fatigue syndrome, and migraine headache is not established. Elderberry's effectiveness for hay fever, heart disease, chronic fatigue, COPD, cognitive function, and respiratory infections is also insufficient to rate.
Olive leaf extract similarly lacks established evidence for osteoporosis, indigestion, exercise-induced respiratory infections, shingles, flu, and osteoarthritis. We hold no effectiveness data for spilanthes.
How safe is it?
Well-documented data
Andrographis is often well tolerated short-term, but long-term safety and product quality aren't well established. Common side effects include stomach discomfort, taste changes, diarrhea, dizziness, fatigue, headache, nausea, vomiting, itching, and rash.
Rare but serious allergic reactions including anaphylaxis have been reported. Echinacea is generally well tolerated, but can cause stomach pain, constipation, diarrhea, heartburn, nausea, vomiting, and rashes.
Severe allergic reactions and hepatitis (liver inflammation) are rare but have occurred — people allergic to ragweed and related plants are at higher risk. Elderberry made from ripe, cooked fruit is well tolerated; raw or unripe berries, seeds, and leaves contain toxins that can cause nausea, vomiting, severe diarrhea, weakness, dizziness, and numbness.
One case of autoimmune hepatitis was reported after long-term elderberry use. Olive leaf extract is generally well tolerated; headache and stomach discomfort occur occasionally, and one case of acne was reported.
Olive tree pollen can trigger seasonal allergies in sensitive people.
Meds to double-check
Moderate interaction found
Before taking Immune Alert, double-check the following medication types with your pharmacist or the search tool below. Blood pressure medications (antihypertensives) — andrographis may lower blood pressure further.
Blood thinners or antiplatelet drugs — andrographis may increase bleeding risk. Immunosuppressants — both andrographis and echinacea can interfere with them.
Drugs metabolized by liver enzyme CYP3A4 and CYP1A2 (a very large category including many statins, blood pressure drugs, cancer medications, and others) — echinacea may affect how quickly your body clears them. Cancer drugs, especially etoposide (VePesid) — echinacea may increase levels to risky heights.
Warfarin (Coumadin) and similar blood thinners — echinacea may speed their clearance. Midazolam (Versed) or similar sedatives — echinacea may reduce effectiveness.
Pazopanib (Votrient) — elderberry may theoretically interact.
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.
This product may help with a few specific conditions — andrographis for ulcerative colitis, sore throat, or joint pain — but most ingredients lack strong evidence. The bigger issue is that it interacts with many medications, especially blood pressure drugs, blood thinners, immunosuppressants, and common cancer and HIV drugs.
If you take any prescription medication, check it against our tool first. Talk to your pharmacist before starting, especially if you're on a blood thinner, immune-suppressing drug, or heart or diabetes medication.

Immune Alert by Herbs Etc. Drug Interactions
HelloPharmacist Interaction Report
Immune Alert by Herbs Etc. does interact with medications.
The most serious concerns involve andrographis and echinacea — both ingredients can affect how your body handles drugs.
Read the full breakdown — every affected drug type, severity by severity
Andrographis raises two Major concerns: it may lower blood pressure (hypotension) when combined with blood pressure medications (antihypertensives), and it may increase bleeding risk with blood thinners or antiplatelet drugs. It can also theoretically interfere with drugs that suppress the immune system (immunosuppressants).
Minor interactions exist with specific pain relievers: etoricoxib (Arcoxia) absorption may drop, while celecoxib (Celebrex) levels might increase. Glipizide (Glucotrol), a diabetes medication, could see higher concentrations, though the effect is unclear.
Echinacea — present in five different forms in this product — interacts with a larger set of medications. The most serious are drugs processed through liver enzyme CYP3A4 (which include many common medications), drugs broken down by CYP1A2 (including caffeine, which echinacea can boost by around 30%), immunosuppressants, and the cancer drug etoposide (VePesid), which can cause more severe blood cell drops.
Minor interactions exist with the blood thinner warfarin (Coumadin), the HIV medication lopinavir/ritonavir (Kaletra), and midazolam (Versed), a sedative.
Elderberry may interfere with immunosuppressants and theoretically interact with pazopanib (Votrient), a cancer medication. Olive leaf extract and spilanthes have no documented interactions we hold data for — we could not check spilanthes.
Altogether, these interactions span 1,017 individual medications.

For each ingredient in Immune Alert 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.
Echinacea purpurea Seed Extract
Caffeine
Echinacea can increase plasma levels of caffeine by inhibiting its metabolism.
Echinacea seems to increase plasma concentrations of caffeine by around 30%. This is likely due to inhibition of cytochrome P450 1A2 (CYP1A2) by echinacea.
Cytochrome P450 1A2 (Cyp1A2) Substrates
Echinacea might inhibit the metabolism of CYP1A2 and increase plasma levels of some drugs.
Echinacea appears to inhibit CYP1A2 enzymes in humans. Additionally, echinacea seems to increase plasma concentrations of caffeine, a CYP1A2 substrate, by around 30%. Theoretically, echinacea might increase levels of other drugs metabolized by CYP1A2.
Cytochrome P450 3A4 (Cyp3A4) Substrates
Echinacea may induce hepatic CYP3A4 and inhibit intestinal CYP3A4. This may increase or decrease levels of drugs metabolized by CYP3A4.
Several clinical trials have shown that taking echinacea for up to one month does not significantly affect the metabolism of various CYP3A4 substrates, including midazolam, docetaxel, etravirine, lopinavir-ritonavir, and darunavir-ritonavir. However, other clinical research shows that echinacea may increase the clearance of midazolam, suggesting that echinacea might induce CYP3A4. The discrepancy is thought to be due to differing effects of echinacea on intestinal versus hepatic CYP3A4 enzymes. Echinacea appears to induce hepatic CYP3A4 but inhibit intestinal CYP3A4. In some cases, these effects might cancel each other out, but in others, drug levels may be increased or decreased depending on the level of effect at hepatic and intestinal sites. The effect of echinacea on CYP3A4 activity may differ depending on the CYP3A4 substrate.
Etoposide (Vepesid)
Echinacea may increase levels of etoposide.
In one report, concomitant use of etoposide and echinacea was associated with more severe thrombocytopenia than the use of etoposide alone, suggesting inhibition of etoposide metabolism. Etoposide is a cytochrome P450 3A4 (CYP3A4) substrate. Echinacea has variable effects on CYP3A4, but some studies have reported inhibition of the enzyme.
Immunosuppressants
Echinacea has immunostimulant activity which may interfere with immunosuppressant therapy.
Theoretically, echinacea may interfere with immunosuppressant therapy because of its immunostimulant activity.
Darunavir (Prezista)
Theoretically, echinacea may interfere with the metabolism of darunavir; however, a small clinical study found no effect.
Darunavir is metabolized by cytochrome P450 3A4 (CYP3A4) and is administered with the CYP3A4 inhibitor ritonavir to increase its plasma concentrations. Echinacea has variable effects on CYP3A4, but administration of an E. purpurea root extract (Arkocapsulas Echinacea, Arkopharma) 500 mg four times daily for 14 days did not affect darunavir/ritonavir pharmacokinetics in 15 HIV-infected patients.
Dayquil Severe
Echinacea is reported to have varying effects on a number of Cytochrome P450 metabolizing enzymes in the liver, including CYP1A2 and CYP3A4, which play a role in acetaminophen and dextromethorphan metabolism (both contained in DayQuil Severe), respectively. Studies have reported both enzyme inhibition and induction, making it difficult to predict clinically significant drug interactions with reliability. Specific drug interaction studies reporting definitive results are rare, and potential drug interactions involving echinacea should likely be taken on a case-by-case basis. Based on what we know about how acetaminophen and dextromethorphan are metabolized, the risk of a clinically significant interaction between echinacea and DayQuil Severe is low.
Docetaxel (Taxotere)
Theoretically, echinacea may interfere with the metabolism of docetaxel; however, a small clinical study found no effect.
Docetaxel is metabolized by cytochrome P450 3A4 (CYP3A4). Echinacea has variable effects on CYP3A4, but taking E. purpurea whole plant extract (Echinaforce, A. Vogel Biopharma AG) 20 drops three times daily for 2 weeks did not alter the pharmacokinetics of docetaxel in one clinical study.
Etravirine (Intelence)
Theoretically, echinacea may interfere with the metabolism of etravirine; however, a small clinical study found no effect.
Etravirine is metabolized by cytochrome P450 3A4 (CYP3A4). Echinacea has variable effects on CYP3A4, but taking E. purpurea root extract (Arkocapsulas Echinacea, Arkopharma) 500 mg three times daily for 14 days did not alter the pharmacokinetics of etravirine in HIV-infected patients.
Lopinavir/Ritonavir (Kaletra)
Theoretically, echinacea may interfere with the metabolism of lopinavir; however, a small clinical study found no effect.
Lopinavir is metabolized by cytochrome P450 3A4 (CYP3A4) and is administered with the CYP3A4 inhibitor ritonavir to increase its plasma concentrations. Echinacea has variable effects on CYP3A4, but taking E. purpurea (Echinamide, Natural Factors Nutritional Products, Inc.) 500 mg three times daily for 14 days did not alter the pharmacokinetics of lopinavir/ritonavir in healthy volunteers.
Midazolam (Versed)
Theoretically, echinacea may increase the metabolism of intravenous midazolam.
Echinacea induces hepatic CYP3A4 and might decrease plasma levels of midazolam by about 20%, reducing the effectiveness of intravenous midazolam. Echinacea also appears to inhibit intestinal CYP3A4, which could theoretically increase the bioavailability of oral midazolam. This may cancel out the decrease in availability caused by induction of hepatic CYP3A4, such that overall plasma levels after oral administration of midazolam are not affected by echinacea.
Warfarin (Coumadin)
Echinacea seems to increase the clearance of warfarin, although the effect may not be clinically significant.
Preliminary clinical research in healthy male volunteers suggests that taking echinacea increases the clearance of the active S-isomer of warfarin after a single dose of warfarin, but there was not a clinically significant effect on the INR.
Andrographis Herb Extract
Anticoagulant/Antiplatelet Drugs
Theoretically, andrographis might increase the risk of bleeding when used with anticoagulant or antiplatelet drugs.
Animal and laboratory studies suggest that andrographis has antiplatelet effects.
Antihypertensive Drugs
Theoretically, andrographis might increase the risk of hypotension when used with antihypertensive drugs.
Animal research suggests that andrographis has hypotensive effects.
Immunosuppressants
Theoretically, andrographis might interfere with the effects of immunosuppressive drugs.
Laboratory research suggests that andrographolide has immunostimulant activity.
Celecoxib (Celebrex)
Theoretically, andrographis extract might increase the maximum concentration and time to peak concentration of celecoxib. The clinical significance of these changes is unclear.
Animal research suggests that andrographis extract taken orally increases the maximum concentration and time to peak concentration of celecoxib but does not appear to impact the area under the curve.
Etoricoxib (Arcoxia)
Theoretically, andrographis might decrease the absorption of etoricoxib, although the clinical significance is unclear.
Animal research shows that andrographis extract, or the constituent andrographolide, taken orally with etoricoxib decreases the bioavailability of etoricoxib. However, this reduced bioavailability is not correlated with a reduction in the anti-inflammatory effects of etoricoxib in arthritic mice models. The clinical significance of this interaction is unclear.
Glipizide (Glucotrol)
Theoretically, andrographis extract might increase the maximum concentration and area under the curve of glipizide; however, opposite effects are seen with the constituent, andrographolide. The clinical significance of this interaction is unclear.
Animal research suggests that andrographis extract taken orally with glipizide in diabetes-induced rats increases the maximum concentration and area under the curve of glipizide. However, the opposite effect is seen with the constituent, andrographolide, in which the maximum concentration and area under the curve are decreased when taken with glipizide.
Elderberry Extract, Fresh
Immunosuppressants
Theoretically, elderberry might interfere with immunosuppressant therapy due to its immunostimulant activity.
Elderberry has immunostimulant activity, increasing the production of cytokines, including interleukin and tumor necrosis factor.
Pazopanib (Votrient)
Theoretically, elderberry might interact with pazopanib, potentially increasing the risk of adverse effects.
