Uses for lansoprazole, amoxicillin, and clarithromycin

Prevpac® is a product containing three components: lansoprazole, amoxicillin, and clarithromycin. Lansoprazole, amoxicillin, and clarithromycin is used to treat patients with H. pylori infection and duodenal ulcers caused by H. pylori bacteria.

Lansoprazole is a proton pump inhibitor (PPI). It works by decreasing the amount of acid produced by the stomach. Amoxicillin and clarithromycin both belong to the class of medicines known as antibiotics. They work by killing bacteria or preventing their growth. However, lansoprazole, amoxicillin, and clarithromycin will not work for colds, flu, or other virus infections.

Lansoprazole, amoxicillin, and clarithromycin is available only with your doctor's prescription.

Before using lansoprazole, amoxicillin, and clarithromycin

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 lansoprazole, amoxicillin, and clarithromycin, the following should be considered:

Allergies

Tell your doctor if you have ever had any unusual or allergic reaction to lansoprazole, amoxicillin, and clarithromycin 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 have not been performed on the relationship of age to the effects of Prevpac® in the pediatric population. Safety and efficacy have not been established.

Geriatric

Appropriate studies performed to date have not demonstrated geriatric-specific problems that would limit the usefulness of Prevpac® in the elderly. However, elderly patients are more likely to have kidney or liver problems, which may require caution and an adjustment in the dose for patients receiving lansoprazole, amoxicillin, and clarithromycin.

Breastfeeding

There are no adequate studies in women for determining infant risk when using this medication during breastfeeding. Weigh the potential benefits against the potential risks before taking this medication while breastfeeding.

Interactions with medicines

In these cases, your doctor may want to change the dose, or other precautions may be necessary.

The following interactions have been selected on the basis of their potential significance and are not necessarily all-inclusive.
