Not e: Acetaminophen-induced hepatotoxicity, which can be life threatening, has been associated with doses >4 g/day. Although doses up to 4 g/day are generally well tolerated (Ref), hepatotoxicity has been reported rarely at this dose limit (Ref). Due to this risk, some experts recommend a lower maximum dose of 3 g/day in adults with normal liver function, particularly when used for longer durations (eg, >7 days) for pain (Ref). Heavy alcohol use, malnutrition, fasting, low body weight, advanced age, febrile illness, select liver disease, and use of drugs that interact with acetaminophen metabolism may increase risk of hepatotoxicity; a lower total daily dose (eg, 2 g/day) or avoidance may be preferred (Ref). When calculating total daily dose, confirm that all sources (eg, prescription, OTCs, combinations) are included.
Migraine, mild to moderate, acute treatment:
Note: Risk of medication-overuse headache may be higher with combination analgesics containing caffeine; limit use to <10 days per month to avoid medication-overuse headache. Administration early in the course of a migraine attack, at the first sign of pain, may improve response to treatment (Ref).
Oral: Acetaminophen 250 mg/aspirin 250 mg/caffeine 65 mg: 2 tablets as a single dose. Maximum: 2 tablets per 24 hours (Ref).

Concerns related to adverse effects:
• Drug reaction with eosinophilia and systemic symptoms: Potentially serious, sometimes fatal, drug reaction with eosinophilia and systemic symptoms (DRESS), also known as multiorgan hypersensitivity reactions, has been reported with nonsteroidal anti-inflammatory drugs (NSAIDs). Monitor for signs and symptoms (eg, fever, rash, lymphadenopathy, eosinophilia) in association with other organ system involvement (eg, hepatitis, nephritis, hematological abnormalities, myocarditis, myositis). Early symptoms of hypersensitivity reaction (eg, lymphadenopathy, fever) may occur without rash; discontinue therapy and further evaluate if DRESS is suspected.
• GI effects: Contains aspirin which may cause stomach bleeding. Risk is increased with ulcers or bleeding problems, using other medications containing an NSAID, ethanol use, or using longer than recommended.
• Hepatotoxicity: Severe liver damage may occur if used with other medications that contain acetaminophen. Limit acetaminophen dose from all sources (prescription and OTC) to ≤4 g/day and avoid or limit ethanol to <3 drinks per day.
• Hypersensitivity reactions: Allergic reactions have been reported with acetaminophen and/or aspirin use.
• Skin reactions: Rarely, acetaminophen may cause serious and potentially fatal skin reactions such as acute generalized exanthematous pustulosis, Stevens-Johnson syndrome (SJS), and toxic epidermal necrolysis (TEN). Discontinue treatment if severe skin reactions develop.
Dosage form specific issues:
• Caffeine: Some products may contain an amount of caffeine similar to one cup of coffee; limit the use of other caffeine-containing beverages or foods.
Special populations:
• Older adult: May have increased risk of severe stomach bleeding in patients 60 years and older.
• Pediatric: Children and teenagers who have or are recovering from chickenpox or flu-like symptoms should not use this product. Changes in behavior (along with nausea and vomiting) may be an early sign of Reye's syndrome; patients should be instructed to contact their health care provider if these occur.
Other warnings/precautions:
• Appropriate use: Use for 10 or more days per month may cause medication overuse headache.
• Self-medication (OTC use): Notify health care provider prior to use if you have asthma, arthritis, diabetes, gout, heart disease, high blood pressure, kidney disease, liver disease, stomach bleeding or history of heartburn, or are taking a diuretic. Discontinue use and contact health care provider for any of the following: allergic reaction, bloody/black stools, feeling faint, fever that gets worse or lasts more than 3 days, hearing loss, pain that gets worse or last more than 10 days, redness or swelling of painful area, ringing in the ears, stomach pain that does not get better, vomiting blood, or if new symptoms occur. When used for migraine, contact health care provider prior to use if you have never had a migraine before, if this migraine is different than normal, if your first migraine was diagnosed at over 50 years of age, if you have a stiff neck and fever, if your migraine requires bed rest, or if your headache occurred following coughing, bending, exertion, or head injury

Beers Criteria: Aspirin, when used chronically at doses more than 325 mg/day, is identified in the Beers Criteria as a potentially inappropriate medication to be avoided in patients 65 years and older (unless alternative agents ineffective and patient can receive concomitant gastroprotective agent) due to increased risk of GI bleeding and peptic ulcer disease in older adults in high risk category (eg, older than 75 years of age or receiving concomitant oral/parenteral corticosteroids, anticoagulants, or antiplatelet agents). In addition, avoid for short-term scheduled use in combination with oral/parenteral corticosteroids, anticoagulants, or antiplatelet agents unless alternatives are ineffective and patient can receive concomitant gastroprotective agent (Beers Criteria [AGS 2023]).
KIDs List: Salicylates, when used in pediatric patients <18 years of age with suspicion of viral illness (influenza, chickenpox), are identified on the Key Potentially Inappropriate Drugs in Pediatrics (KIDs) list and should be used with caution due to risk of Reye syndrome (weak recommendation; very low quality of evidence) (PPA [Meyers 2020]).
