Nexium relieves heartburn and other symptoms caused by the backflow of stomach acid into the canal to the stomach (the esophagus)—a condition known as gastroesophageal reflux disease. It is also indicated to heal the damage (erosive esophagitis) that reflux disease can cause.
Prescribed in combination with the antibiotics amoxicillin and clarithromycin, Nexium is also used to treat the infection that causes most duodenal ulcers (ulcers occurring just beyond the exit from the stomach).
Nexium works by reducing the production of stomach acid.
Use Nexium as directed by your doctor.
- Take Nexium at least one hour before meals.
- Be careful to swallow it whole. If you have trouble swallowing capsules, you can open the capsule and carefully pour the pellets onto one tablespoon of applesauce. The applesauce should not be hot. Mix in the pellets, then swallow the applesauce immediately, without chewing.
- If you miss a dose of Nexium, take it as soon as you remember. If it is almost time for your next dose, skip the one you missed and go back to your regular schedule. Never take 2 doses at the same time.
Ask your health care provider any questions you may have about how to use Nexium.
Store Nexium at room temperature, between 68 and 77 degrees F (20 and 25 degrees C). Store away from heat, moisture, and light. Keep Nexium out of the reach of children and away from pets.
