Guaifenesin+Dextromethorphan+Phenylephrine is used in the treatment of nasal congestion and dry cough.

This is a combination of three medicines: Guaifenesin, dextromethorphan and phenylephrine which relieve cough and cold symptoms. Guaifenesin is an expectorant which decreases the stickiness of mucus (phlegm) and helps in its removal from the airways. Dextromethorphan is a cough suppressant that relieves cough by reducing the activity of cough centre in the brain. Phenylephrine is a decongestant which narrows the small blood vessels providing relief from congestion or stuffiness in the nose.
