GENERALLY SAFE TO FLY
The FAA's over-the-counter guide lists guaifenesin (found in Mucinex and Robitussin) in its "Generally Safe to Fly" column, with caution because combination products may contain sedating antihistamines; if the label states PM (for nighttime use) or DM (containing dextromethorphan), it says not to fly while using these medications and for at least 5 dosage intervals after the last dose.
