Understanding the 'Cough Q' product family
The term “Cough Q” is often used generically to refer to a variety of branded medications, such as Kuff Q, Cof Q, and Q-Tussin, that treat cough and cold symptoms. Because the ingredients differ across these products, it is vital to check the label and understand the specific formulation to match it to your symptoms. The main distinction is whether the product is formulated for a wet (productive) cough or a dry (non-productive) cough.
Formulations for wet or chesty cough
Some versions of 'Cough Q' products are designed to address productive coughs, which produce mucus or phlegm. These formulations are common for chest congestion associated with conditions like bronchitis, asthma, or common colds. Key ingredients often include Guaifenesin, an expectorant, Bromhexine, a mucolytic, and Terbutaline, a bronchodilator.
Formulations for dry cough
Other formulations are specifically for dry, irritating coughs that do not produce mucus. These products contain antitussive or cough-suppressant ingredients to calm the cough reflex.
Key ingredients may include Dextromethorphan, a cough suppressant, Phenylephrine, a nasal decongestant, and Chlorpheniramine, an antihistamine.
A note on herbal products
Some products branded as 'Cough Q' might also be herbal formulations containing ingredients like plantain lanceolate, thyme, basil, and eucalyptus. Always check the packaging to confirm the active ingredients.

Avoid use with certain medications, especially monoamine oxidase (MAO) inhibitors, due to interaction risks. The safety of these products during pregnancy or while breastfeeding is often not established, and consultation with a healthcare provider is best.
