Tanafed DP suspension

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

Tanafed DP 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.

Tanafed DP suspension is an antihistamine and decongestant combination. The antihistamine works by blocking the action of histamine, which helps reduce symptoms such as watery eyes and sneezing. The decongestant promotes sinus and nasal drainage, relieving congestion and pressure.

  • you have severe high blood pressure, severe heart blood vessel disease, rapid heartbeat, or severe heart problems
  • you are unable to urinate or are having an asthma attack

Contact your doctor or health care provider right away if any of these apply to you.
