A patient is allergic to acetylsalicylic acid (aspirin). Which of the following medications is contraindicated due to cross-hypersensitivity reactions?
A) Acetaminophen (Tylenol)
B) Naproxen sodium (Naprosyn)
C) Morphine sulfate (MS Contin)
D) Naloxone (Narcan)
B
Feedback:
In people who have demonstrated hypersensitivity to aspirin, all nonaspirin NSAIDs are contraindicated because cross-hypersensitivity reactions may occur with any drugs that inhibit prostaglandin synthesis. Acetaminophen (Tylenol) does not have cross-sensitivity with acetylsalicylic acid (aspirin) because it is not an NSAID. Morphine sulfate (MS Contin) does not have a cross-sensitivity to aspirin because it is an opioid, not an NSAID. Naloxone (Narcan) is an opioid antagonist and does not have cross-sensitivity with aspirin.
