One active ingredient is the whole argument for Delsym. There's no expectorant and no decongestant in the orange suspension, just dextromethorphan polistirex, an extended-release cough suppressant, and the label spaces doses twelve hours apart. When you're standing in an aisle working out what you can safely take alongside what, a bottle that does exactly one thing is easier to be sure of.
That one thing is what most of us need at two in the morning. We tested this against a dry, tickly cough that had already outlasted every lozenge in the house, and the twelve-hour stretch was what we kept noticing: one dose before bed instead of a bottle, a cup, and a phone flashlight at 3 a.m. It doesn't make you drowsy, so the same bottle covers the daytime, and the orange flavor is mild enough that you're not bracing for it.
Twelve hours is also the catch. If your cough breaks through around hour eight, you can't top up the way you can with a shorter-acting liquid, which is where the CoughGels below come in. And this is a suppressant, full stop: with a wet, chesty cough you want an expectorant in the mix, and Robitussin DM Max is the pick for that. For the dry cough that arrives with a cold and settles in for a week, this is the bottle that stays on the nightstand.
Pros
- One ingredient, nothing extra to check
- Twelve hours of relief per dose
- Non-drowsy, so it works in the daytime
- Mild orange flavor that doesn't linger
Cons
- Smallest bottle of the liquids here
For the cough that keeps you up, this is the bottle we keep on the shelf: one ingredient, a dose every twelve hours, and no drowsiness to sleep off.
