Good to know
- Children's Delsym and adult Delsym 12 Hour Cough Relief have the same active ingredient at the same strength (dextromethorphan polistirex equivalent to 30 mg dextromethorphan HBr per 5 mL) and the same dosing directions by age; the children's box says "For Children & Adults".
- Delsym's active ingredient is dextromethorphan bound to a resin (polistirex) so it is released over 12 hours; the strength is stated as the equivalent amount of dextromethorphan HBr.
- Other Delsym-branded products, such as Delsym Cough + Chest Congestion DM and Delsym Nighttime Cough, contain different ingredient combinations.
