HelloPharmacist Scorecard of Activated Charcoal 840 mg by NusaPure

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: activated charcoal powder at 840 mg per capsule. Activated charcoal is a form of carbon that's been processed to be highly porous, which allows it to bind to substances in your digestive tract.

The capsule also contains inactive ingredients — cellulose, silica, and rice powder — which are fillers and binders that help form the capsule.

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

This product doesn't appear to be marketed for a specific use, so we graded Activated Charcoal's overall clinical evidence instead.

Moderate

Some clinical evidence supports Activated Charcoal for:

Why this rating?
  • We looked at the product name, claims, and label statements and couldn't find a stated purpose to grade.
  • Since the label doesn't commit to one use, we graded the ingredient's overall clinical evidence instead.
  • On file: Poisoning — rated "Possibly Effective" (Natural Medicines).

Activated charcoal is possibly effective for poisoning when used as directed, typically in an emergency setting under medical supervision. For other uses — including high blood phosphate levels, wound healing, indigestion, hangover, and high cholesterol — the evidence we hold is insufficient to rate whether it works.

If you're considering it for any of these other reasons, talk with your pharmacist or doctor about what the research actually supports.

The evidence, ingredient by ingredient Activated Charcoal

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.

Activated charcoal is generally well tolerated for short-term use, but it does carry some risks. The most common side effects are gastrointestinal: constipation (often the main complaint), black stools, abdominal pain, bloating, and gas.

These are usually temporary. Rarely, it can cause gastrointestinal obstruction or — if inhaled — lung irritation.

Safety data for routine use in pregnancy and breastfeeding is limited. The evidence rates it possibly safe, but it hasn't been well studied for ongoing use in these settings.

If you're pregnant or breastfeeding and considering activated charcoal, talk with your doctor or pharmacist for personalized guidance.

Known Interaction Concern · database check
Major identified

At least one ingredient has a documented Major-severity interaction. Check your medications for a personalized result.

Why this rating?
  • 1 of the 1 matched ingredient can interact with medications — Activated Charcoal.
  • The most serious interaction on file is rated Major.
  • For scale: 2,028 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 taking this product, double-check any oral medications you take (Major severity) — activated charcoal can reduce how much of them your body absorbs. Also ask about oral contraceptives (Moderate) and whether drinking alcohol with it changes how it works (Moderate).

The bottom line

Scorecard at a glanceFully disclosed formula with some supporting evidence behind its ingredients' uses. Major medication interactions have been identified, and safety information is well characterized.

Activated charcoal may help in acute poisoning cases under medical care, but it interacts with a very large number of medications by reducing their absorption. If you take any regular medications — especially oral contraceptives, heart drugs, or pain relievers — check with us before you start.

For other uses, the evidence isn't strong enough to recommend it.

activated Charcoal powder3 drug types · 2,027 drugs

Oral Drugs

Activated charcoal reduces systemic exposure to many drugs, including those that undergo enterohepatic recirculation, regardless of the route of administration.
Activated charcoal adsorbs various drugs and may reduce their absorption and/or half-life. Examples of affected drugs include acetaminophen, aminophylline, amiodarone, atenolol, carbamazepine, dapsone, digoxin, disopyramide, fluoxetine, indomethacin, moxifloxacin, nadolol, phenytoin, phenobarbital, piroxicam, quinine, sotalol, theophylline, tricyclic antidepressants, valproate, and verapamil. Avoid co-administration, except after drug overdose.

Likelihood Probable Evidence B
Alcohol (Ethanol)

The binding action of activated charcoal may be reduced by alcohol.
Alcohol may lower the adsorptive capacity of activated charcoal.

Likelihood Probable Evidence D
Contraceptive Drugs

Activated charcoal may reduce the clinical effects of oral contraceptives.
Activated charcoal, taken in a dose of 5 grams four times daily for 3 days, may bind to, and reduce the absorption of, oral contraceptives, thereby limiting their effectiveness and increasing the risk of contraceptive failure. However, some clinical research shows that the risk for this interaction is minimal when activated charcoal is taken either 3 hours after or at least 12 hours before oral contraceptives.

Activated Charcoal 840 mg by NusaPure: Common Questions

Does Activated Charcoal 840 mg by NusaPure interact with any medications?
Yes. Based on its ingredients, Activated Charcoal 840 mg has a known interaction with 2,027 medications, including 2022 rated major. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Activated Charcoal 840 mg contains a single active ingredient, and that one ingredient can interact with many different medications on its own. We check it against each medication and show the mechanism 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.
Does activated charcoal really bind everything?
No — it binds to many drugs and substances, but not all. It's especially effective at adsorbing compounds that circulate back through your liver (enterohepatic recirculation). That's why it can affect so many medications. The best approach is to check your specific drugs with our search tool.
When should I take it relative to my other medications?
We don't have the specifics on timing in our data. Because activated charcoal can interfere with absorption, spacing matters — your pharmacist can tell you the exact gap you need between this and each of your medications.
Will it really make my birth control fail?
Activated charcoal may reduce oral contraceptive absorption and effectiveness, but some research suggests the effect might be limited in practice. Don't assume you're protected — talk with your doctor or pharmacist about whether it's safe to use together and what backup you might need.
Is it safe to take during pregnancy?
The evidence rates it possibly safe, but it hasn't been well studied for routine use in pregnancy. There isn't enough data to know either way. Talk with your doctor or pharmacist before starting it — they can give you personalized advice based on your situation.
What are the most common side effects?
Constipation is the most frequent complaint, followed by black stools, abdominal pain, bloating, and gas — all gastrointestinal. These are usually temporary. Rarely, it can cause a bowel blockage.
Can I use this for a hangover?
Activated charcoal is listed as having insufficient evidence to rate for hangover relief in our data. We don't have enough research to say whether it actually works for that purpose.
