IMPORTANT NOTE: The following information is intended to supplement, not substitute for, the expertise and judgment of your physician, pharmacist or other healthcare professional. It should not be construed to indicate that use of the drug is safe, appropriate or effective for you. Consult your healthcare professional before using this drug.

Generic Name: LANSOPRAZOLE/AMOXICILLIN/CLARITHROMYCIN - ORAL
Pronounced: (lan-SOE-pra-zole/a-MOX-i-SIL-in/kla-RITH-roe-MYE-sin)

Prevpac Oral Uses

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). Unnecessary use or misuse of any antibiotic can lead to its decreased effectiveness.

How To Use Prevpac Oral

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.

Antibiotics work best when the amount of medicine in your body is kept at a constant level. Therefore, take this product regularly and at evenly spaced intervals to get the most benefit from it. Remember to take it at the same times each day. Continue to take this product until the full prescribed amount is finished, even if symptoms disappear after a few days. Stopping antibiotics too early may allow bacteria to continue to grow, which may result in a return of the infection.

Tell your doctor if your condition persists or worsens.
