VanaCof DX liquid

Generic Name: chlophedianol/guaifenesin/pseudoephedrine (KLOE-fe-DYE-a-nol/gwye-FEN-e-sin/SOO-doe-e-FED-rin)
Brand Name: VanaCof DX

VanaCof DX liquid is used for:

Relieving symptoms of nasal congestion, cough, and throat and airway irritation caused by colds, hay fever, or other upper respiratory allergies. It may also be used for other conditions as determined by your doctor.

VanaCof DX liquid is a decongestant, cough suppressant, and expectorant combination. The decongestant works by constricting blood vessels and reducing swelling in the nasal passages. The expectorant works by loosening mucus and thinning lung secretions in the chest, making coughs more productive. The cough suppressant works in the brain to help decrease the cough reflex.

Do NOT use VanaCof DX liquid if:

  • you are allergic to any ingredient in VanaCof DX liquid
  • you have severe or uncontrolled high blood pressure, rapid heartbeat, or other severe heart problems (eg, heart blood vessel disease)
  • you take droxidopa or have taken furazolidone or a monoamine oxidase inhibitor (MAOI) (eg, phenelzine) within the last 14 days

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