Dyphylline and guaifenesin

Dyphylline is a bronchodilator. It works by relaxing muscles in the airways to improve breathing.

Guaifenesin is an expectorant. It helps loosen congestion in your chest and throat, making it easier to cough out through your mouth.

Dyphylline and guaifenesin is a combination medicine used to treat cough and breathing problems caused by conditions such as bronchial asthma, chronic bronchitis, or emphysema.

This medication is not a rescue medication for asthma or bronchitis, and is not a cure for emphysema.

Dyphylline and guaifenesin may also be used for purposes not listed in this medication guide.

Ask a doctor or pharmacist before using any cough or cold medicine. Guaifenesin is contained in many combination medicines. Taking certain products together can cause you to get too much guaifenesin.
