Overview

This formula combines Dextromethorphan HBr for cough suppression and Guaifenesin for mucus thinning. Dextromethorphan HBr is effective at the stated dose for cough relief. While Guaifenesin helps to loosen phlegm, its direct impact on cough frequency itself is more variable; however, its mechanism supports clearing chest congestion. The combined action provides comprehensive relief for both dry and productive coughs caused by minor throat and bronchial irritation typically associated with common colds.

The Good

Provides dual-action relief by suppressing cough and thinning mucus.

Dextromethorphan HBr is a clinically proven cough suppressant.

Guaifenesin helps to clear chest congestion effectively.

The Bad

Mixed evidence for Guaifenesin efficacy for cough suppression, as it helps clear mucus but isn't an antitussive.

Potential for side effects like nausea, vomiting, dizziness, and headache, particularly with Guaifenesin.

Dextromethorphan HBr can cause drowsiness and dizziness, impairing activities requiring alertness.

Is it for you?
