What is hoarseness?

Hoarseness is an abnormal deep, harsh voice caused by a variety of conditions.

What causes hoarseness?

Hoarseness is generally caused by irritation of, or injury to, the vocal cords. The larynx (also referred to as the voice box), is the portion of the respiratory (breathing) tract containing the vocal cords. The cartilaginous outer wall of the larynx is commonly referred to as the "Adams apple." The vocal cords are two bands of muscle that form a "V" inside the larynx. When we sing or speak, the vocal cords vibrate and produce sound.

Hoarseness can be caused by a number of conditions. The most common cause of hoarseness is acute laryngitis (inflammation of the vocal cords) caused by an upper respiratory tract infection (usually viral), and less commonly from overuse or misuse of the voice (such as from yelling or singing).

Other causes of hoarseness include:

benign vocal cord nodules or polyps,
gastroesophageal reflux (GERD),
allergies,
inhalation of irritants/smoking,
thyroid problems,
trauma to the larynx/vocal cords,
neurological conditions (Parkinson's disease and strokes), and
cancer of the larynx.

Uses of KAPIDEX

Persistent heartburn two or more days a week, despite treatment and diet changes, could be acid reflux disease (ARD). Prescription KAPIDEX capsules are used in adults to treat heartburn related to ARD, to heal acid-related damage to the lining of the esophagus (called erosive esophagitis or EE), and to stop EE from coming back. Individual results may vary. Most damage (erosions) heals in 4�8 weeks.

Talk to your doctor or healthcare professional. Please see full Prescribing Information for KAPIDEX.
