DayQuil and Tylenol: the quick answer
- Don’t take them together. Both contain acetaminophen.
- An hour apart doesn’t help. It’s still two doses stacking up.
- Ibuprofen is the safe add-on. Advil or Motrin doesn’t double anything.
- Switching later is fine. Stop DayQuil, then make Tylenol your next dose.
- Too much acetaminophen hurts your liver, sometimes before you feel anything.

How long after DayQuil can you take Tylenol?
Only once you've stopped DayQuil, and no sooner than your next dose is due. DayQuil is every 4 hours, so wait at least 4 hours after your last dose, and count both toward one daily total. Going the other way, wait until your next Tylenol dose is due (6 hours after Extra Strength) before switching to DayQuil.
