This product is used to treat stomach/intestinal ulcers caused by the bacteria H. pylori and to prevent the ulcers from returning. Treating an ulcer reduces the risk of serious damage to the lining of the stomach/intestines (such as bleeding, tearing, blockage).
Lansoprazole is known as a proton pump inhibitor (PPI). It works by blocking acid production in the stomach. Decreasing excess stomach acid can help the ulcer heal. Amoxicillin and clarithromycin are antibiotics used to treat a wide variety of bacterial infections (including H. pylori). Treating the infection helps reduce the risk of the ulcer returning. Amoxicillin is a penicillin-type antibiotic and clarithromycin is a macrolide-type antibiotic. They work by stopping the growth of bacteria.
The antibiotics in this product treat only bacterial infections. Antibiotics do not work for viral infections (such as common cold, flu). Using any antibiotic when it is not needed can cause it to not work for future infections.
Lansoprazole is not recommended for use in children younger than 1 year due to an increased risk of serious side effects. Ask the doctor or pharmacist for details.
Take this medication by mouth exactly as directed by your doctor, usually 1 dose (4 pills) twice daily before a meal. Swallow the lansoprazole capsules whole. Do not crush or chew.
Each packet contains both the morning and evening doses of this medication (a 1-day supply). Consult your doctor or pharmacist for instructions on the proper use of this product. The dosage and length of treatment is based on your medical condition and response to treatment.
For the best effect, take this product at evenly spaced times. To help you remember, take this product at the same times every day. Continue to take this medication until the full prescribed amount is finished, even if symptoms disappear after a few days. Stopping the medication too early may result in a return of the infection.
Tell your doctor if your condition lasts or gets worse.
