Guaifenesin is an expectorant that helps thin and loosen mucus in the airways, making it easier to cough up. Taking it at night might disrupt sleep because it can stimulate coughing as it works to clear mucus. If nighttime cough is problematic, it may be advisable to consult a healthcare provider for alternative treatments or timing adjustments.
