Which component is common to all listed analgesics (Vicodin, Percocet, Tylenol 1–4)?

• A. Acetaminophen
• B. Ibuprofen
• C. Aspirin
• D. Caffeine

Answer: (A)

All three analgesics pair an opioid with acetaminophen. Vicodin combines hydrocodone and acetaminophen; Percocet combines oxycodone and acetaminophen; Tylenol 1–4 are acetaminophen with codeine. So acetaminophen is the ingredient common to all. This is why it’s used to boost pain relief while allowing lower opioid doses. Ibuprofen and aspirin are NSAIDs, not part of these specific formulations, and caffeine isn’t a standard ingredient in these combinations. Remember the safety point: avoid exceeding the daily acetaminophen limit to protect the liver, especially when taking multiple products that may contain acetaminophen.
