Nighttime Cough

Generic Name: dextromethorphan/doxylamine (DEX-troe-meth-OR-fan/dox-IL-a-meen)
Brand Name: Nighttime Cough

Nighttime Cough is used for:

Relieving symptoms of runny nose, sneezing, and cough due to colds, upper respiratory infections, and allergies. It may also be used for other conditions as determined by your doctor.

Nighttime Cough is a cough suppressant and antihistamine combination. The antihistamine works by blocking the action of histamine, which helps reduce symptoms, such as watery eyes and sneezing. The cough suppressant works in the brain to reduce dry or unproductive cough.

  • you are allergic to any ingredient in Nighttime Cough
  • you are unable to urinate or are having an asthma attack
  • you take sodium oxybate (GHB) or you 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.
