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 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 bleeding: Aspirin may cause severe stomach bleeding; risk factors include patients ≥60 years; history of stomach ulcers or bleeding problems; coadministration with anticoagulants or steroids; coadministration with other NSAIDs; ≥3 alcoholic drinks every day during therapy; and prolonged use or administration of more than the recommended dose.
• Hypersensitivity: Aspirin may cause a severe allergic reaction, including hives, skin reddening, facial swelling, rash, asthma, blisters, and/or shock. If an allergic reaction occurs, discontinue use immediately.
• Salicylate sensitivity: Patients with sensitivity to tartrazine dyes, nasal polyps, and asthma may have an increased risk of salicylate sensitivity.
Disease-related concerns:
• Ethanol use: Heavy ethanol use (>3 drinks/day) can increase bleeding risks and may enhance gastric mucosal damage.
Special populations:
• 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 healthcare provider if these occur.
Other warnings/precautions:
• Self-medication (OTC use): When used for self-medication, do not exceed recommended dose. Contact a health care provider before use if you have a history of GI problems (including ulcers) and stomach problems that last or come back (heartburn, upset stomach, pain); bleeding problems; are on a sodium-restricted diet; coadministration with a diuretic, anticoagulant or a prescription medication for diabetes, gout, or arthritis, or if you have asthma, hypertension, cardiac disease, hepatic cirrhosis, or renal disease. Discontinue use if any of the following occur: feeling faint; vomiting blood; bloody or black stools; stomach pain that does not get better; pain gets worse or lasts >10 days; fever gets worse or lasts >3 days; difficulty swallowing; ringing in the ears or loss of hearing; redness or swelling in the painful area; or any new symptoms appear.

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 of age (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, >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]).
