What is Robitussin Dry Cough Medicine?

Robitussin Dry Cough Medicine can help to treat dry, persistent and uncomfortable coughs.  Robitussin also helps to soothe discomfort caused by coughing. Robitussin liquid cough medicine is easy to administer and its soothing effects can last up to 8 hours. If you are looking for soothing and effective relief from dry coughs, try Robitussin Dry Cough Medicine.  

What causes a cough?

A dry cough tends to be tickly and can be irritating. Unlike a chesty cough, it doesn’t produce any thick mucus. Experiencing a short-term cough is common and can be caused by a variety of factors including:

  • An upper respiratory tract infection that affects the throat, windpipe or sinuses, such as cold, flu, laryngitis, sinusitis or whooping cough
  • A lower respiratory tract infection that affect your lungs or lower airways, such as bronchitis or pneumonia
  • An allergy, such as allergic rhinitis or hay fever
  • A flare-up of a long-term condition such as asthma, COPD or chronic bronchitis 
  • Inhalation of dust or smoke

Most short-term coughs will clear up within 3 weeks. If your cough does not improve after a couple of weeks, see advice from your doctor, as it may be a sign of an illness or condition. 

How can Robitussin treat a dry cough?

The active ingredient in Robitussin Dry Cough medicine is dextromethorphan, which belongs to a group of medicines called cough suppressants. It works by providing effective relief from persistent dry, irritating coughs. The formula is non-drowsy, so can be administered during the day. The liquid format is easy to administer.
