Pain reliever stacking checker: what two over-the-counter products add up to in 24 hours

Answer the question people actually type — “can I take Tylenol and Aleve in the same day, and how much is too much?” — with the numbers off the labels instead of a guess.

Add Up A Day's Doses Against The Label

Pain reliever stacking checker: what two over-the-counter products add up to in 24 hours

Pick up to two over-the-counter pain relievers and how many label doses of each you would take in a day. This adds the acetaminophen, naproxen sodium and ibuprofen and compares the totals to the ceilings printed on the Drug Facts labels.

Uses: First product · Doses of the first product in 24 hours · Second product · Doses of the second product in 24 hours

This is an arithmetic check against published Drug Facts labels, not medical advice, not a dosing instruction, and not a safety clearance. It cannot know what else you take or what conditions you have. Read the label on every product you use, and ask a pharmacist or your doctor before combining pain relievers — especially if you have liver, kidney, heart or stomach conditions, take blood thinners, are pregnant, or drink alcohol regularly. If you think someone has taken too much acetaminophen, call Poison Control at 1-800-222-1222 immediately, even if they seem fine.

Example — adjust the inputs above for your situation

Within the label limits: 3,000 mg acetaminophen, 660 mg naproxen sodium and 0 mg ibuprofen in 24 hours.

Acetaminophen and an NSAID work on pain differently, which is why labels do not forbid taking them in the same day — the danger is quantity, and the totals above are under the published ceilings. That holds only if these are the only products you take: check everything else in the cabinet for the same ingredients.

Acetaminophen in 24 hours
3,000 mg (liver warning above 4,000 mg)
Naproxen sodium in 24 hours
660 mg (label ceiling 660 mg)
Ibuprofen in 24 hours
0 mg (label ceiling 1,200 mg)
First product
3 × 2 caplets (1,000 mg acetaminophen) every 6 hours
Second product
3 × 1 caplet (220 mg naproxen sodium) every 8 to 12 hours
  • ※ This tool only counts what you tell it. Acetaminophen is also in many cold, flu, sinus, allergy and night-time products, and prescription pain medicines — check every label for it.
  • ※ Label ceilings assume a healthy adult taking the product for a short time. Liver disease, kidney disease, heart disease, stomach ulcers, blood thinners, pregnancy and regular alcohol use all change the arithmetic, and your doctor's directions override the carton.
  • ※ Not medical advice and not a dosing instruction. If the number is close to a limit, or you are unsure, ask a pharmacist — they will answer this question for free.

How this is calculated

Straight addition against published Drug Facts labels. Each product contributes a fixed milligram amount per label-directed adult dose: TYLENOL Regular Strength 650 mg acetaminophen per 2-tablet dose, Extra Strength 1,000 mg per 2-caplet dose, 8 HR Arthritis Pain 1,300 mg per 2-caplet dose, TYLENOL with Naproxen 650 mg acetaminophen plus 220 mg naproxen sodium per dose, Aleve 220 mg naproxen sodium per caplet, and Advil 400 mg ibuprofen per 2-tablet dose. Doses are multiplied out, summed by active ingredient, and compared with the labels' own 24-hour ceilings: 4,000 mg is the acetaminophen figure named in the liver-damage warning (3,000 mg is the ceiling on the Extra Strength carton), 660 mg for naproxen sodium and 1,200 mg for ibuprofen without a doctor's direction. Two separate NSAIDs together, and two acetaminophen products together, are flagged regardless of the totals. There is no clinical model here and no personalisation — it counts milligrams.

Assumptions, limitations & sources

Assumptions

  • · A healthy adult or child 12 and over taking the products short-term exactly as the label directs.
  • · One 'dose' means the label's standard adult dose for that product, shown in the result.
  • · Only the two products entered are counted — the tool cannot know about anything else in the medicine cabinet.
  • · TYLENOL with Naproxen contributes 650 mg acetaminophen and 220 mg naproxen sodium per dose, per the manufacturer's approval announcement; its own 24-hour ceiling has not been published yet.

Limitations

  • · Not medical advice, not a dosing instruction, and no substitute for the Drug Facts label or a pharmacist.
  • · Acetaminophen is an ingredient in hundreds of combination cold, flu, sinus, allergy and night-time products and in prescription pain medicines. Those are the doses that push people over the line, and this tool cannot see them.
  • · Label ceilings assume no complicating conditions. Liver disease, kidney disease, heart disease, a history of stomach ulcers or bleeding, blood thinners, pregnancy, and regular alcohol use all change what is safe, and a doctor's directions override the carton.
  • · NSAID warnings this tool does not weigh: naproxen and ibuprofen carry FDA warnings about heart attack, stroke and gastrointestinal bleeding, and both labels cap continuous use without a doctor at 10 days for pain.
  • · The full Drug Facts label for TYLENOL with Naproxen has not been published yet, so its own maximum daily doses cannot be checked here. Follow the carton.

The story behind this tool

Health

The FDA approved a Tylenol that contains naproxen — what that means for the bottle already in your cabinet

TYLENOL with Naproxen puts 650 mg of acetaminophen and 220 mg of naproxen sodium in a single over-the-counter dose — the first fixed-dose combination of its kind. It also makes an old question urgent: if one pill now contains both, how do you avoid doubling up?
