Heartburn (cont.)

Heartburn Symptoms
The pain of heartburn is described as a burning feeling in the chest. Often, the sensation may spread up into the throat, jaw, arms, or back. That's why heartburn is often mistaken for chest pain due to a heart attack. However, do not second guess yourself. If you are having chest pain for any reason, seek medical attention immediately, if only to rule out a heart attack.
Heartburn (often called acid indigestion) typically occurs 30-60 minutes after meals. The pain is worse when lying down, bending forward, and straining to pass stools. The pain is relieved by standing upright, swallowing saliva or water, or by taking antacids.
- If small amounts of stomach acid or food travel beyond the esophagus and up into the mouth, you may experience bitter or sour taste. This is known as regurgitation. It is common after meals, especially if you are lying down, bending over, or straining.
- Stomach acid can also affect the respiratory tract, causing asthma, hoarseness, chronic cough, sore throat, or tooth
damage (acid eats the enamel on teeth). You may feel as if you have a lump in
your throat.
- If the acid exposure continues for long periods of time, the esophagus becomes damaged. You may then have difficulty swallowing. In more serious cases, you may lose weight and become dehydrated. Very rarely, the esophagus may bleed or tear completely because it is so damaged. In severe cases, you may vomit blood or have small amounts of blood in your bowel movements. However, all these are uncommon.

Important Safety Information
- KAPIDEX may not be right for everyone. You should not take KAPIDEX if you are allergic to KAPIDEX or any of its ingredients. Severe allergic reactions have been reported.
- Symptom relief does not rule out other serious stomach conditions.
- The most common side effects of KAPIDEX were diarrhea (4.8%), stomach pain (4.0%), nausea (2.9%), common cold (1.9%), vomiting (1.6%), and gas (1.6%). KAPIDEX and certain other medicines can affect each other. Before taking KAPIDEX, tell your doctor if you are taking ampicillin, atazanavir, digoxin, iron, ketoconazole, or tacrolimus. If you are taking KAPIDEX with warfarin, you may need to be monitored because serious risks could occur.
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.
