Quick Scoop

For most DayQuil products , adults and teens 12+ can take it every 4 hours as needed , with no more than 4 doses in 24 hours. Some versions, like DayQuil Intense Flu , may have different directions, so the label matters.

Safe use

  • Do not exceed the package directions. Taking more can raise the risk of serious side effects, including liver damage from acetaminophen.
  • Check other cold/flu meds first. Many products contain acetaminophen, so combining them can accidentally double up.
  • Use the measuring cup or syringe for liquid DayQuil instead of a kitchen spoon.

When to get help
