Relieving congestion and cough due to colds, flu, or hay fever. It may also be used for other conditions as determined by your doctor.
Maxifed-G CDX is a decongestant, cough suppressant, and expectorant combination. The decongestant works by constricting blood vessels and reducing swelling in the nasal passages.
