This product is a highly effective, standard-of-care treatment for its specific indications, but loses some points for potential side effects and drug interactions.
Pharmacist's Verdict
Robitussin DM Max is a classic, effective combination for quieting a nagging cough while also helping to break up mucus in your chest. It's a reliable workhorse for the common cold, but it's not the best choice if you only have one type of symptom.

Cons
- Can cause drowsiness, dizziness, and nausea; do not drive until you know how it affects you.
