HelloPharmacist Scorecard of Andrographis Extract 400 mg by NOW

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 12, 2026

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 1 of its 1 active ingredient.
  • No proprietary blends here — you can verify the dose of every single component.

This product contains one active ingredient: andrographis extract at 400 mg per capsule. Andrographis is a plant used traditionally in Southeast Asian medicine, and the extract concentrates its active compounds.

The capsule also holds inactive ingredients — hypromellose (the capsule material), rice flour, stearic acid, and silicon dioxide — which are fillers and binders that help hold the tablet together.

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: supports immune function and seasonal wellness.
  • We looked for evidence on: Acute bronchitis, Influenza, Rhinosinusitis, Tonsillopharyngitis, Upper respiratory tract infection (URTI), Coronavirus disease 2019 (COVID-19) — and 3 related terms.
  • The strongest evidence on file: Andrographis is rated "Possibly Effective" for Tonsillopharyngitis (Natural Medicines).
  • Also on file: Andrographis is rated "Insufficient Reliable Evidence To Rate" for Acute bronchitis, Upper respiratory tract infection (URTI), Influenza, Rhinosinusitis, and more.

The evidence for andrographis is still developing. Research suggests it may be possibly effective for ulcerative colitis, sore throat and tonsillopharyngitis, and osteoarthritis.

However, for familial Mediterranean fever, we don't yet have enough reliable evidence to rate it. If you're considering this supplement for one of those conditions, talk with your pharmacist or doctor about what the current research shows and whether it makes sense for you.

The evidence, ingredient by ingredient Andrographis

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 1 of the 1 matched ingredient.
  • Pregnancy & breastfeeding safety ratings cover 1 of 1.
  • General safety write-ups exist for 1 of 1.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Andrographis is generally well tolerated when used short-term, though the quality of products on the market and long-term safety data aren't well established. At typical doses it's usually fine, but side effects become more likely at higher doses (5–10 mg/kg of andrographolide content) or if you take it for longer than two weeks.

The most common side effects are stomach discomfort, altered taste, diarrhea, dizziness, fatigue, headache, nausea, vomiting, itching, and rash. Severe allergic reactions, including anaphylaxis, are rare but possible.

Skin reactions — including rash, itching, hives, and rarely Stevens-Johnson syndrome — have also been reported. During pregnancy, safety data raises concerns; the evidence advises against use.

While breastfeeding, there isn't enough safety information, so it's best to avoid it. If you're pregnant, planning to become pregnant, or breastfeeding, talk with your pharmacist or doctor before taking this product.

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?
  • 1 of the 1 matched ingredient can interact with medications — Andrographis.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: anticoagulant / antiplatelet drugs; immunosuppressants / transplant drugs.
  • For scale: 413 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 you start, double-check with your pharmacist if you take blood pressure medications, blood thinners or antiplatelet drugs like warfarin or aspirin, or immunosuppressive drugs. Also run through this if you're on etoricoxib (Arcoxia), celecoxib (Celebrex), or glipizide (Glucotrol).

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.

Andrographis may be worth considering if you're dealing with sore throat, ulcerative colitis, or osteoarthritis and want to explore plant-based options. If you take blood pressure medications, blood thinners, immunosuppressants, or certain pain relievers or diabetes drugs, check with your pharmacist first — this supplement could affect how those work.

Avoid it during pregnancy and while breastfeeding.

Andrographis extract6 drug types · 413 drugs

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.

Likelihood Possible Evidence D
Antihypertensive Drugs

Theoretically, andrographis might increase the risk of hypotension when used with antihypertensive drugs.
Animal research suggests that andrographis has hypotensive effects.

Likelihood Possible Evidence D
Immunosuppressants

Theoretically, andrographis might interfere with the effects of immunosuppressive drugs.
Laboratory research suggests that andrographolide has immunostimulant activity.

Likelihood Possible Evidence D
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.

Likelihood Possible Evidence D
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.

Likelihood Possible Evidence D
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.

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.
What is andrographis used for?
Research suggests andrographis may help with sore throat and tonsillopharyngitis, ulcerative colitis, and osteoarthritis. The evidence for each is still developing — it's rated possibly effective for these uses.
Can I take this while pregnant or breastfeeding?

What side effects might I notice?
Most common are stomach discomfort, altered taste, diarrhea, dizziness, fatigue, headache, nausea, and rashes. These happen more often at higher doses (5–10 mg/kg of the active compound) or if you take it longer than two weeks. Severe allergic reactions are rare but possible.
How long is it safe to take andrographis?
Andrographis is generally well tolerated short-term. Side effects are more likely if doses reach or exceed 5–10 mg/kg of andrographolide or if you take it for longer than 14 days. Long-term safety isn't well established.
Will this interact with my blood pressure or blood thinner medications?
Possibly. Andrographis may lower blood pressure further and increase bleeding risk with blood thinners. Talk with your pharmacist before starting, especially if you take medications for either condition.
