Chlorcyclizine/Phenylephrine Syrup


Pronunciation: klor-SYE-klih-zeen/FEN-il-EF-rin
Generic Name: Chlorcyclizine/Phenylephrine
Brand Name: Dallergy


Chlorcyclizine/Phenylephrine Syrup is used for:

Relieving symptoms of sinus congestion; pressure; runny nose; itching of the nose or throat; itchy, watery eyes; and sneezing due to colds, hay fever, or allergies. It may also be used for other conditions as determined by your doctor.


Chlorcyclizine/Phenylephrine Syrup 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, which relieves congestion and pressure.

  • you are allergic to any ingredient in Chlorcyclizine/Phenylephrine Syrup

  • you have severe or uncontrolled 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

  • you take droxidopa or sodium oxybate (GHB), or you have taken furazolidone or a monoamine oxidase inhibitor (MAOI) (eg, phenelzine) within the last 14 days
