Cautions
For rectal use only
Avoid overdose by checking product labels carefully; acetaminophen is found in many dosage forms and many combination products
If not sure whether a drug contains acetaminophen, ask a physician or a pharmacist
If experiencing liver disease, ask a physician or a pharmacist before using
Ask a physician or pharmacist if taking warfarin or blood-thinning products
Discontinue use and ask a physician if fever lasts >3 days (72 h) or recurs, pain lasts >5 days continuously or recurs
Use caution in patients with known G6PD deficiency
Risk of hepatotoxicity is higher in alcoholics, chronic high dose
Risk for rare, but serious skin reactions that can be fatal; these reactions include Stevens-Johnson Syndrome (SJS), toxic epidermal necrolysis (TEN), and acute generalized exanthematous pustulosis (AGEP); symptoms may include skin redness, blisters and rash

Pregnancy category: B; Crosses placenta, safe to use in all stages of pregnancy short term
Lactation: Excreted in breast milk; compatible w/ breastfeeding
Pregnant or breastfeeding patients should seek advice of health professional before using OTC drugs
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
Inhibits prostaglandin synthesis in the CNS and works peripherally to block pain impulse generation; acts on hypothalamus to produce antipyresis
Pharmacokinetics

Half-life: 2.4 hr (adolescents); 2-3 hr (adults); 2-5 hr (children); 4-10 hr (neonates)
Plasma Time: 107-288 min
Peak Plasma Concentration: dose-dependent; (10 mg/kg) 5.5 mcg/mL, (20 mg/kg) 8.8 mcg/mL, (30 mg/kg) 14.2 mcg/mL
Protein Bound: 10-25% (therapeutic concentrations); 43% (toxic concentrations)
Distribution: 1 L/kg
Metabolism: Liver (microsomal enzyme systems); conjugation (glucuronic/sulfuric acid)
Metabolites: N-acetyl-p-benzoquinoneimine, N-acetylimidoquinone, NAPQI; further metabolized via conjugation with glutathione
Excretion: <5% is excreted in the urine as unconjugated (free) acetaminophen and 60-80% as glucuronide metabolites
