Duotan PD suspension
Generic Name: dexchlorpheniramine/pseudoephedrine (dex-klor-fen-IR-a-meen/soo-doe-e-FED-rin)

Duotan PD suspension is used for:
Relieving congestion, sneezing, runny nose, nasal or throat itching, and itchy or watery eyes caused by colds, hay fever, or other allergic conditions. It may also be used for other conditions as determined by your doctor.
