Description
Lansoprazole is used to treat certain conditions where there is too much acid in the stomach. It is used to treat duodenal and gastric ulcers, gastric ulcers caused by NSAID use, erosive esophagitis, and gastroesophageal reflux disease (GERD). GERD is a condition wherein the acid in the stomach washes back up into the esophagus. Sometimes lansoprazole is used in combination with antibiotics (eg, amoxicillin, clarithromycin) to treat ulcers associated with an infection caused by H. pylori bacteria.
Lansoprazole is also used to treat Zollinger-Ellison syndrome (ZES), which is a condition where the stomach produces too much acid.
Lansoprazole is a proton pump inhibitor (PPI). It works by decreasing the amount of acid produced by the stomach.
This medicine is available both over-the-counter (OTC) and with your doctor's prescription.
This product is available in the following dosage forms:
- Capsule, Delayed Release
- Tablet Disintegrating, Delayed Release
- Powder for Suspension
Before Using
In deciding to use a medicine, the risks of taking the medicine must be weighed against the good it will do. This is a decision you and your doctor will make. For this medicine, the following should be considered:

Tell your doctor if you have ever had any unusual or allergic reaction to this medicine or any other medicines. Also tell your health care professional if you have any other types of allergies, such as to foods, dyes, preservatives, or animals. For non-prescription products, read the label or package ingredients carefully.
Pediatric
Appropriate studies performed to date have not demonstrated pediatric-specific problems that would limit the usefulness of lansoprazole to treat GERD and erosive esophagitis in children 1 to 17 years of age. Safety and efficacy have not been established in children younger than 1 year of age. This medicine may increase the risk for heart problems (eg, heart valve thickening) in children younger than 1 year of age.
Geriatric
Appropriate studies performed to date have not demonstrated geriatric-specific problems that would limit the usefulness of lansoprazole in the elderly. However, elderly patients are more sensitive to the effects of this medicine than younger adults.

Lansoprazole may cause a serious type of allergic reaction when used in patients with conditions treated with antibiotics. Call your doctor right away if you or your child has itching, trouble breathing or swallowing, or any swelling of your hands, face, or mouth.
Check with your doctor right away if you have a change in frequency of urination or amount of urine, blood in the urine, fever, joint pain, loss of appetite, skin rash, swelling of the body or feet and ankles, unusual tiredness or weakness, or unusual weight gain. These could be symptoms of a serious kidney problem called acute tubulointerstitial nephritis.
Taking this medicine for a long time may make it harder for your body to absorb vitamin B12. Tell your doctor if you have concerns about vitamin B12 deficiency.
Serious stomach conditions may occur while taking this medicine alone or together with antibiotics. Check with your doctor immediately if you or your child has stomach cramps, bloated feeling, watery and severe diarrhea which may also be bloody sometimes, fever, nausea or vomiting, or unusual tiredness or weakness.
Lansoprazole may increase your risk of having fractures of the hip, wrist, and spine. This is more likely if you have osteoporosis, if you are 50 years of age and older, if you receive high doses of this medicine, or if you use it for one year or more. Call your doctor right away if you have severe bone pain or are unable to walk or sit normally.

This medicine may cause hypomagnesemia (low magnesium in the blood). This is more likely to occur if you are taking this medicine for more than one year, or if you are taking this medicine together with digoxin (Lanoxin®) or certain diuretics or "water pills".
