Warnings
Black Box Warnings
Ibuprofen
-
Cardiovascular risk

- Risk may increase with duration of use
- Patients with existing cardiovascular disease or risk factors for such disease may be at greater risk
- NSAIDs are contraindicated for perioperative pain in setting of coronary artery bypass graft (CABG) surgery
-
Gastrointestinal risk
- NSAIDs increase risk of serious GI adverse events, including bleeding, ulceration, and gastric or intestinal perforation, which can be fatal
- GI adverse events may occur at any time during use and without warning symptoms
- Elderly patients are at greater risk for serious GI events
Contraindications
Ibuprofen
- Hypersensitivity to ibuprofen, other NSAIDs, aspirin, or excipients
- Perioperative pain in setting of CABG surgery
Acetaminophen
- Hypersensitivity
- Severe active liver disease
Cautions
Acetaminophen
-
Hepatotoxicity risk
- Risk of hepatotoxicity is higher in patients taking long-term high dose, or use of more than one acetaminophen-containing product
- Acetaminophen is available in many dosage forms and products; check label carefully to avoid overdose
- Limit acetaminophen dose from all sources and routes to <4 g/day in adults
- Consumption of 3 or more alcoholic drinks/day may increase risk of liver damage
-
Allergic reaction
- Risk for rare, but serious skin reactions that can be fatal; these reactions include Stevens-Johnson syndrome, toxic epidermal necrolysis, and acute generalized exanthematous pustulosis; symptoms may include skin redness, blisters, and rash
- Discontinue if symptoms occur and seek medical help immediately
Ibuprofen
If pregnant or breastfeeding, ask a health professional before use; it is especially important not to use ibuprofen at 20 weeks or later in pregnancy unless definitely directed to do so by a doctor; it may cause problems in the unborn child or complications during delivery
Keep out of reach of children; in case of overdose, get medical help or contact a poison control center right away; prompt medical attention is critical for adults as well as for children even if you do not notice any signs or symptoms
-
NSAID allergy
- May cause severe allergic reaction, especially in patients allergic to aspirin
- Symptoms may include hives, asthma, skin redness, blisters, rash, facial swelling, and shock
- Discontinue if symptoms occur and seek medical help immediately
-
GI bleeding
- NSAIDs increase risk of serious GI adverse events, including bleeding, ulceration, and gastric or intestinal perforation, which can be fatal
- Risk is higher with patients who are aged ≥60 yr, have history of peptic ulcer disease or GI bleeding, take anticoagulants or corticosteroids, take aspirin or other NSAIDs, consume ≥3 alcoholic drinks every day while taking this drug, or take a higher dose or for a longer duration than recommended
-
Cardiovascular risk
- NSAIDs, except aspirin, increase risk of MI, heart failure, and stroke, which can be fatal
- Higher risk if higher dose consumed or taken longer than directed
-
Renal injury
- Long-term administration of NSAIDs may result in renal papillary necrosis and other renal injury
- Patients at greatest risk include elderly individuals and those with impaired renal function, hypovolemia, heart failure, liver dysfunction, or salt depletion
- Risk increased if coadministered with diuretics, ACE inhibitors, or angiotensin receptor blockers
Pregnancy & Lactation
Pregnancy
Ibuprofen
- Ask a health professional before use; it is especially important not to use ibuprofen at 20 weeks or later in pregnancy unless definitely directed to do so by a doctor because it may cause problems in the unborn child or complications during delivery; NSAID use during third trimester increases risk of premature closure of the fetal ductus arteriosus
- There are no adequate and well-controlled studies in pregnant women; data from observational studies regarding potential embryofetal risks of NSAID use in women in the first or second trimesters of pregnancy are inconclusive
Acetaminophen
- Low risk of cryptorchidism in boys if used for several weeks or longer
Lactation
Ibuprofen
- Considered compatible with breastfeeding (LactMed)
- No lactation studies have been conducted; however, limited published literature reports that following oral administration, ibuprofen is present in human milk at relative infant doses of 0.06-0.6% of the maternal weight-adjusted daily dose
Acetaminophen
- Considered compatible with breastfeeding (LactMed)
Pregnancy Categories
A: Generally acceptable. Controlled studies in pregnant women show no evidence of fetal risk.
B: May be acceptable. Either animal studies show no risk but human studies not available or animal studies showed minor risks and human studies done and showed no risk. C: Use with caution if benefits outweigh risks. Animal studies show risk and human studies not available or neither animal nor human studies done. D: Use in LIFE-THREATENING emergencies when no safer drug available. Positive evidence of human fetal risk. X: Do not use in pregnancy. Risks involved outweigh potential benefits. Safer alternatives exist. NA: Information not available.Pharmacology
Mechanism of Action
Acetaminophen
- Acts on hypothalamus to produce antipyresis
- May work peripherally to block pain impulse generation; may also inhibit prostaglandin synthesis in CNS
Ibuprofen
- Elicits anti-inflammatory, analgesic, and antipyretic activity
- Inhibits synthesis of prostaglandins in body tissues by inhibiting at least 2 cyclooxygenase (COX) isoenzymes, COX-1 and COX-2
- May inhibit chemotaxis, alter lymphocyte activity, decrease proinflammatory cytokine activity, and inhibit neutrophil aggregation; these effects may contribute to its anti-inflammatory activity
Administration
Oral Administration
Take with food or milk if GI distress occurs
Storage
Store at 20-25ºC (68-77ºF); avoid excessive heat >40ºC (104ºF)
