How does this medication work? What will it do for me?

This is a product that contains three separate medications: lansoprazole, clarithromycin, and amoxicillin. Lansoprazole belongs to the group of medications called proton pump inhibitors (PPIs). Clarithromycin and amoxicillin belong to the group of medications called antibiotics. Together these medications are used to treat H. pylori (bacteria that cause inflammation in the stomach) for people with a duodenal ulcer (an ulcer at the beginning of the small intestine).

These medications are also used to reduce the risk of another duodenal ulcer for people who have recently had a duodenal ulcer and who have tested positive for H. pylori. Lansoprazole helps to lower the acidity of the stomach, which helps the antibiotics (clarithromycin and amoxicillin) kill the bacteria and heal the ulcer.

This medication may be available under multiple brand names and/or in several different forms. Any specific brand name of this medication may not be available in all of the forms or approved for all of the conditions discussed here. As well, some forms of this medication may not be used for all of the conditions discussed here.

Your doctor may have suggested this medication for conditions other than those listed in these drug information articles. If you have not discussed this with your doctor or are not sure why you are taking this medication, speak to your doctor. Do not stop taking this medication without consulting your doctor.

Do not give this medication to anyone else, even if they have the same symptoms as you do. It can be harmful for people to take this medication if their doctor has not prescribed it.

How should I use this medication?

The usual adult dose of this combination of medications is 30 mg of lansoprazole, 500 mg of clarithromycin and 1 g of amoxicillin (2 × 500 mg capsules), twice a day before meals for 7, 10, or 14 days.

Lansoprazole capsules should be swallowed whole with water – do not crush, break, or chew them.

Many things can affect the dose of medication that a person needs, such as body weight, other medical conditions, and other medications. If your doctor has recommended a dose different from the ones listed here, do not change the way that you are taking the medication without consulting your doctor.

It is important to take this medication exactly as prescribed by your doctor and to finish all this medication. Not doing so may decrease the effectiveness of this medication and may increase the chances of bacteria developing resistance to amoxicillin and clarithromycin.

If you miss a dose, take it as soon as possible and continue with your regular schedule. If it is almost time for your next dose, skip the missed dose and continue with your regular dosing schedule. Do not take a double dose to make up for a missed one. If you are not sure what to do after missing a dose, contact your doctor or pharmacist for advice.

Are there any other precautions or warnings for this medication?

Before you begin taking a medication, be sure to inform your doctor of any medical conditions or allergies you may have, any medications you are taking, whether you are pregnant or breast-feeding, and any other significant facts about your health. These factors may affect how you should take this medication.

Abnormal heart rhythm: Clarithromycin may cause a heart rhythm problem called QT prolongation. If you have a history of QT prolongation, a medical condition associated with QT prolongation, or are taking certain medications (e.g., amiodarone, sotalol), discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed.

Allergic reactions: Some people who are allergic to penicillin or cephalosporins also experience allergic reactions to amoxicillin. Some people who are allergic to erythromycin or azithromycin also experience allergic reactions to clarithromycin. Before you take lansoprazole - clarithromycin - amoxicillin, inform your doctor about any previous adverse reactions you have had to medications, especially penicillin or erythromycin antibiotics. Contact your doctor at once if you experience signs of an allergic reaction, such as skin rash, itching, difficulty breathing, or swelling of the face and throat.

Diarrhea: Diarrhea is a common side effect of antibiotics such as amoxicillin and clarithromycin. Diarrhea usually stops when the antibiotic is finished. However, a serious condition called pseudomembranous colitis can occur. If you develop severe watery and bloody diarrhea (with or without stomach cramps and fever) any time during treatment or up to 1 or 2 months after stopping this medication, contact your doctor.

Kidney function: A safe and effective dose of lansoprazole - clarithromycin - amoxicillin for people with reduced kidney function has not been determined. If you have kidney disease or decreased kidney function, discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed.

Liver function: Liver disease or reduced liver function may cause clarithromycin or lansoprazole to build up in the body, causing side effects. If you have liver problems, discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed. Your doctor may want to test your liver function regularly with blood tests while you are taking this medication.

Clarithromycin may also cause a decrease in liver function. If you experience symptoms of liver problems such as fatigue, feeling unwell, loss of appetite, nausea, yellowing of the skin or whites of the eyes, dark urine, pale stools, abdominal pain or swelling, and itchy skin, contact your doctor immediately.

Methotrexate: When taken together, proton pump inhibitors such as lansoprazole may cause methotrexate to build up in the body, causing severe side effects, including possible death. Methotrexate is used to treat certain types of cancer, arthritis, and gastrointestinal disease. If you are taking methotrexate for any reason, discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed.

Myasthenia gravis: Myasthenia gravis is a condition that causes specific muscle weakness. Clarithromycin may cause symptoms of myasthenia gravis to occur or become worse. If you have myasthenia gravis, discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed.

Stomach cancer: Lansoprazole can improve some of the symptoms of stomach cancer and make it harder for a doctor to diagnose it.

Subacute cutaneous lupus erythematosus (SCLE): Rarely, this medication has been associated with SCLE, an autoimmune disease. If you develop any skin lesions, especially in sun-exposed skin areas, and if accompanied by muscle aches or pains, contact your doctor immediately.

Pregnancy: This medication should not be used during pregnancy, especially during the first 3 months, unless the benefits outweigh the risks. If you become pregnant while taking this medication, contact your doctor immediately.

Breast-feeding: Amoxicillin and clarithromycin pass into breast milk. It is not known if lansoprazole passes into breast milk. If you are breast-feeding and taking this medication, it may affect your baby. Talk to your doctor about whether you should continue breast-feeding.

Children: The safety and effectiveness of using this combination of medications have not been established for children.

Seniors: Due to the possibility of reduced kidney and liver function, seniors should discuss with their doctor how this medication may affect their medical condition, how their medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed.
