NCT ID NCT06716645
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This completed study looked at how two different Robitussin cough syrup regimens affect quality of life in 244 adults with coughs from the common cold. One group used a single daytime/nighttime syrup, while the other used separate daytime and nighttime syrups. Researchers measured changes in symptoms and daily functioning using a standard cold questionnaire.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
Active substance
Dextromethorphan and guaifenesin (daytime); dextromethorphan and doxylamine (nighttime)
What this could lead to
If the results are positive, this could confirm that these over-the-counter cough syrups help people feel better and function more normally while they have a cold.
What could go wrong
This is a completed real-world study, not a tightly controlled trial, so results may be influenced by factors like how people naturally recover from a cold. The findings are unlikely to change standard care.
