How Many Excedrin Can You Take? The Box Changes the Answer

For adults, the dose on both main Excedrin boxes is 2 caplets. The Excedrin Migraine label says not to take more than 2 caplets in 24 hours unless a doctor tells you to. The Excedrin Extra Strength label allows 2 caplets every 6 hours, up to 8 in 24 hours. If you already took more than your box allows, call Poison Control at 1-800-222-1222 (1-844-764-7669 in Canada), even if you feel fine.

Here is the strange part. Both boxes hold the same pill: acetaminophen 250 mg, aspirin 250 mg and caffeine 65 mg per caplet, according to their labels (Migraine, Extra Strength). FDA's files from the 1990s show where that 2 came from.

How Many Excedrin Can You Take at Once or in a Day?

"Excedrin" is a family of products without one shared number, and store brands copy these formulas, so check the Drug Facts on your own bottle.

So for a single dose, all four labels above give the same answer: 2 caplets. The daily line is where they split. The PM label adds that drowsiness will occur, not to drive, and not to use it with any other diphenhydramine product, even one used on skin.

Some people should not go by these numbers at all. The aspirin boxes warn that children and teens who have or are recovering from chickenpox or flu-like symptoms should not use them, because of Reye's syndrome. If you are pregnant or breastfeeding, the labels say to ask a health professional first. The current FDA-approved Migraine Relief carton also says not to use aspirin "at 20 weeks or later in pregnancy" unless a doctor directs it (the DailyMed Migraine label we link still says the last 3 months). They also say to ask a doctor before use if you have liver disease, stomach ulcers or bleeding problems, high blood pressure, heart or kidney disease, or asthma (Migraine label, Extra Strength label).

Why Does Excedrin Migraine Say 2 When Extra Strength Says 8?

Extra Strength is sold under FDA's standing rules for over-the-counter pain relievers. DailyMed files it as an "OTC monograph" product, and its label covers minor aches and pains, headache included.

Excedrin Migraine took another road. In 1997 the maker filed a new drug application, NDA 20-802, to put "migraine" on the box. FDA's naming committee wrote that the product "is identical to a companion product called EXCEDRIN EXTRA STRENGTH." It added that "The application data was necessary to gain the additional labeling of Migraine" (FDA file).

That data came from three trials. In each, adults with diagnosed migraine took one dose of two tablets, or a placebo, for one attack. FDA's 1997 medical review concluded that "Two tablets of Excedrin* Extra-Strength is a dosage effective" for moderate or severe migraine pain. In the published trials, 59.3% of 602 adults with migraine who took the drug had pain down to mild or none at 2 hours. On placebo, it was 32.8%. People whose attacks usually needed bed rest, or who vomited in 20% or more of attacks, were left out.

The first Migraine label did not stop at one dose. FDA's 1999 safety review says the 1998 approval came "without any change in the recommended dose range": 2 every 6 hours, up to 8 in 24 hours. In 1999, citing other migraine drug labels, FDA's neurology team leader wrote that "if the first dose is not effective, the diagnosis should be reconsidered prior to taking additional doses," calling it "a safety concern": a more serious condition can look like a migraine. The 1999 label in FDA's file then said "take 2 tablets," and to stop and ask a doctor if "your migraine is not relieved or worsens after first dose." By the 2003 label, the directions also said "do not take more than 2 tablets in 24 hours, unless directed by a doctor," and that line is still on the box.

The liver warning repeats each box's own number. FDA's rule for over-the-counter acetaminophen sets the wording: "more than [insert maximum number of daily dosage units] in 24 hours, which is the maximum daily amount." Each box fills in its own directions, so Migraine says 2 and Extra Strength says 8. Either way, each label says severe liver damage may occur past its own number.

You may read that the 2-caplet limit exists to prevent rebound headaches. Neither FDA's 1997 medical review nor that 1999 memo, both read in full, mentions rebound. The safety review adds that one dose may lower the risk of ear ringing and hearing loss. The Migraine box's overuse warning came later, in 2017, at FDA's request, and it counts days per month, not caplets per day.

So the 2 on the Migraine box is the one tested dose, kept to one so a migraine it does not help gets checked. It does not mean the pill is weaker, and it does not let you use the Extra Strength number for a migraine. (For what the same label says about drinking, see Excedrin and alcohol.)

Took 3, 4 or 6 Excedrin? What the Milligrams Add Up To

Here is the math for Excedrin Migraine and Extra Strength caplets, which are the same pill. It is arithmetic, not a safety rating. It does not fit Tension Headache caplets, which have 500 mg of acetaminophen each, or the PM box, which adds a sleep aid.

Past 8 caplets, you are over both lines. The Extra Strength column is not a backup limit for a Migraine box.

Both labels give one instruction for taking too much (Migraine label): "In case of overdose, get medical help or contact a Poison Control Center right away." So if you went past your box's line, call Poison Control at 1-800-222-1222. MedlinePlus gives that number to call "right away," and poisonhelp.org has an online tool. In Canada, call 1-844-764-7669, or 1-800-463-5060 in Quebec (Health Canada). Have the box, the number of caplets, the time, and anything else with acetaminophen you took today, but do not delay the call to find them. (Doubled a different medicine? See took medication twice.)

Feeling fine is not a reason to skip the call. The label says quick help matters "even if you do not notice any signs or symptoms," and MedlinePlus notes acetaminophen overdose symptoms "may not occur until 12 or more hours" later (more in took too much Tylenol). Call 911 if someone collapses, has a seizure, is confused or hard to wake, or is breathing very fast. MedlinePlus lists these among the signs of aspirin overdose.

If you took a lot on purpose, or you are having thoughts of hurting yourself, you deserve help right now. Call 911 or Poison Control. In the U.S., you can also call or text the 988 Suicide & Crisis Lifeline at 988. In Canada, 988 is the suicide crisis helpline.

Can You Take Excedrin With Tylenol, NyQuil or Ibuprofen?

Count the acetaminophen in every box you took today, Excedrin included. Under "Do not use," both Excedrin labels (Migraine, Extra Strength) list "with any other drug containing acetaminophen (prescription or nonprescription)."

• Tylenol Extra Strength has 500 mg per caplet. Its directions say not more than 6 caplets in 24 hours unless a doctor directs, and its liver warning names more than 4,000 mg of acetaminophen in 24 hours.
• NyQuil Cold & Flu LiquiCaps have 325 mg each, so the usual 2-LiquiCap dose is 650 mg. See Tylenol with NyQuil.
• Some prescription pain pills pair an opioid with acetaminophen, like Norco.

Two Excedrin Migraine (500 mg) plus two Tylenol Extra Strength (1,000 mg) is 1,500 mg of acetaminophen, from two boxes that each say not to combine them. In a 2012 study of 500 adults asked to show how they would take store-bought acetaminophen over a day, 45.6% would have gone over by "double-dipping" with two products.

Ibuprofen and naproxen raise a different issue. The aspirin in Excedrin Migraine and Extra Strength is an NSAID. The Migraine label says the chance of severe stomach bleeding is higher if you take other NSAIDs, naming ibuprofen and naproxen. Ask your pharmacist before you combine them.

How Many Days a Month Can You Take Excedrin?

The Migraine label answers with a warning, not an allowance: "Headaches may worsen if this product is used for 10 or more days per month." That is medication overuse headache, once called rebound headache, as StatPearls on the NIH's bookshelf explains.

The same 10 shows up in the International Headache Society's ICHD-3, which uses "≥10 days/month for >3 months" for combination pain relievers. It counts caffeine as part of what makes a product a combination. Single pain relievers, like plain acetaminophen or ibuprofen, get 15 or more days instead, per StatPearls.

It counts days, not caplets: a day with any Excedrin is a day on the count. And 10 days is a warning sign, not a diagnosis. ICHD-3 also requires headaches on 15 or more days a month. Staying under 10 is not a guarantee either.

Extra Strength counts the same way. The six Extra Strength labels we checked on DailyMed do not print this overuse warning, but ICHD-3's count is about what is in the pill, and the pill is identical. Five of those labels say to stop use and ask a doctor if pain gets worse or lasts more than 10 days (example).

The Migraine label also says to ask a doctor before use if "you have daily headaches." Near 10 days most months? That is the talk to have, because the headaches are the thing to treat. If you also use a triptan, see how often you can take sumatriptan.

Took Excedrin Migraine and Still Have a Headache?

The Migraine label says to stop and ask a doctor if "your migraine is not relieved or worsens after first dose." Its directions still cap you at 2 caplets in 24 hours unless a doctor directs otherwise.

Sometimes the headache is not one Excedrin should treat. The Migraine label says to ask a doctor before use if migraines were never diagnosed, if this headache is different from your usual ones, if it is "the worst headache of your life," if you have a fever and stiff neck, if it started after a head injury, exertion, coughing or bending, if your first headache came after age 50, if a migraine is so severe you need bed rest, or if you have vomiting with your migraine (threw up a dose? see vomiting after taking medication).

Some cannot wait. MedlinePlus says a sudden, "explosive or violent" headache needs emergency care, and to get help right away for a headache that is "the worst ever" or comes with fever and a stiff neck, slurred speech, vision changes or weakness.

The Migraine label also says to stop using it and ask a doctor for signs of stomach bleeding (feeling faint, vomiting blood, bloody or black stools, stomach pain that does not get better) or ringing in the ears or hearing loss. For an allergic reaction, such as hives, facial swelling or wheezing, or a skin reaction such as reddening, blisters or rash, it says to stop use and seek medical help right away.

How Pillo Helps

Two things here come down to memory: what you already took today, and how many days this month you reached for a pain reliever.

Pillo's Medication List keeps every medicine you take in one place, so a second acetaminophen product is easier to catch. For daily medicines, the persistent alarm keeps going until you respond, and Adherence Reporting tracks your history. For Excedrin itself, jot down each date so you can answer "how often?" at your next visit. Pillo is free for unlimited medications, with ads.

FAQ

Is Excedrin Migraine the same as Excedrin Extra Strength?

Same pill, different label. Both have acetaminophen 250 mg, aspirin 250 mg and caffeine 65 mg per caplet, and FDA's naming committee called them "identical" in 1997, but Migraine says not more than 2 caplets in 24 hours unless a doctor directs, while Extra Strength allows up to 8. Follow the box you are using.

Can I take Excedrin and Tylenol together?

The Excedrin labels list "any other drug containing acetaminophen" under "Do not use," and Tylenol is acetaminophen. If you already took both, add up the acetaminophen from each box and call Poison Control at 1-800-222-1222 (1-844-764-7669 in Canada) or a pharmacist.

Can I take ibuprofen after Excedrin?

Ask a pharmacist first. Excedrin Migraine and Extra Strength contain aspirin, an NSAID, and the Migraine label says the chance of severe stomach bleeding is higher if you also take other NSAIDs such as ibuprofen, or if you are 60 or older, have had ulcers or take a blood thinner.

Can you take Excedrin Migraine two days in a row?

The Migraine label counts its limit per 24 hours and its overuse warning per month: headaches may worsen if it is used on 10 or more days a month. If you need it day after day, the label says to ask a doctor, since it lists daily headaches as a reason to check first.

Does the caffeine in Excedrin add up with coffee?

Yes. Two caplets have 130 mg of caffeine, which the Migraine label calls "about as much caffeine as a cup of coffee," and it says to limit other caffeine while you take it. The FDA cites 400 mg a day as an amount not generally linked to negative effects for most adults.
