  • side/adverse effect: nephrotoxicity (most serious), hepatotoxicity, GI distress, headache, hearing loss, peripheral neuritis, rash, K↓, anemia


4. acetaminophen (Tylenol)

  • Acetaminophen inhibits prostaglandin synthesis. Acetaminophen is used to decrease pain and fever, not used to decrease inflammation.
  • Acetaminophen is contraindicated in clients with hepatic or renal disease, alcoholism, and/or hypersensitivity.
  • side/adverse effect: anorexia, nausea, vomiting, hepatotoxicity, hypoglycemia, oliguria, rash
  • Monitor liver enzyme test results. Instruct the client that self-medication should not be used longer than 10 days for an adult and 5 days for a child.
  • maximum 4g/day
  • Note that the antidote for acetaminophen is acetylcysteine (Mucomyst).


  • Non-Steroidal Anti-Inflammatory drugs are aspirin and aspirin-like medications that inhibit the synthesis of prostaglandins. The medications act as an analgesic to relieve pain, an antipyretic to reduce body temperature, and an anticoagulant to inhibit platelet aggregation.
    ex) ibuprofen (Motrin IB, Advil), ketorolac (Toradol), indomethacin (Indocin)
  • NSAIDs are contraindicated in clients with hypersensitivity or liver or renal disease.
  • side/adverse effect: hepatotoxicity, gastric irritation, decreased renal function, tinnitus, blurred vision, dysrhythmias, blood dyscrasias, cardiovascular thrombotic events, dizziness, headache
  • Monitor for signs of bleeding such as tarry stools, bleeding gums, petechiae, ecchymosis, and purpura. Instruct the client to take the medication with water, milk, or food. An enteric-coated or buffered form of aspirin can be taken to decrease gastric distress. Clients taking aspirin should sit upright for 20 to 30 minutes after taking the dose. Note that aspirin should be discontinued 3 to 7 days before surgery to reduce the risk of bleeding. Clients taking anticoagulants should not take aspirin or NSAIDs. Aspirin and NSAIDs should not be taken together because aspirin decreases the blood level and the effectiveness of the NSAIDs and can increase the risk of bleeding. Instruct the client to avoid alcoholic beverages.
