Prevpac (Lansoprazole, Clarithromycin, Amoxicillin)
What is Prevpac?
Prevpac is combination treatment of lansoprazole, amoxicillin, and clarithromycin. This medication treatment is used to combat bacterial infections involving H. pylori or duodenal ulcers in your gut.
Amoxicillin is a form of penicillin antibiotic. It prevents bacteria from making cell walls which are the protective covering they need to survive.
Clarithromycin is a macrolide antibiotic. This stops bacteria from making the proteins they need to grow and survive.
Lansoprazole is known as a proton pump inhibitor (PPI). It prevents a bump in your stomach from making protons, which help with acid formation in your gut. Your stomach tends to be calmer when there is less acid present, so taking this medication can help with symptoms like heartburn or acid reflux.
Altogether, this course of treatment creates an inhospitable environment for H. pylori in the gut, working to ease unwanted symptoms such as stomach and intestinal ulcers, burping, nausea, and stomach pain.
How does Prevpac work?
The components of Prevpac eradicate stomach and intestinal ulcers caused by the bacteria H. pylori. The combination of drugs works by blocking acid production and stopping growth of harmful bacteria in the stomach to help the ulcer heal.
Treating ulcers reduces the risk of damage to the lining of the gut, including but not limited to bleeding, tearing, and blockage. This course of treatment allows the gut to heal by reducing acid and limiting production of bacteria.
Antibiotics do not work for viral infections like the common cold or flu. Prevpac should only be used to treat bacterial infections.
A standard dosage of Prevpac is generally 1 dose of 4 pills, taken twice daily before a meal. The capsules are meant to be taken whole, by mouth. One pro of this course of medications is that it is often take in a short course of 10 to 14 days. It comes in a convenient pack form to ensure adequate dosage and comprehensive treatment.
For adults, this often includes 30 milligrams of lansoprazole, 1000 mg of amoxicillin (2 capsules), and 500 mg of clarithromycin.
Each packet of Prevpac contains the morning and evening doses of this medication. The length of treatment for this medication should be determined by a medical professional based on your medical condition and response to treatment.
Taking antibiotics for an extended period or when it is not needed can cause it not to work for future infections, so it is best to take only for the duration recommended by your provider. For best results, take Prevpac at consistent times each day. Even if symptoms go away, take the medication until the full prescribed amount is complete. Stopping antibiotics earlier than recommended can cause harmful bacteria to grow, which can result in return or worsening of infection.
If you condition lasts or worsens, notify your provider as soon as possible.
If someone experiences symptoms, namely fainting or trouble breathing, call emergency services (911) or a poison control center immediately. US resident can call 1-800-222-1222 to reach their local poison control center.
If you miss a dose, take it as soon as you remember. If this is close to your next dose, skip the missed dose and take as you usually would at your regular time. Do not double dose.

Warnings & Precautions
Before taking Prevpac, consult your doctor of pharmacist and notify them if you are allergic to lansoprazole, amoxicillin, or clarithromycin, or penicillin.
You should also notify your provider if you have a medical history that includes:
- liver disease
- kidney disease
- heart disease
- muscle disease
- infectious mononucleosis
Clarithromycin can cause a condition that affects heart rhythm, called QT prolongation. QT prolongation can, in rare cases, cause fast or irregular heartbeat and other symptoms such as dizziness, fainting which require immediate medical attention.
The risk of developing this condition may increase if you are taking certain medications that may also cause QT prolongation. Tell your doctor if you have a heart problem (e.g. slow heartbeat, EKG irregularities, heart failure) or family history of certain heart issues. Low levels of potassium or magnesium can also increase risk. This risk may increase if you are taking certain diuretics or experience other symptoms like severe sweating, diarrhea, or vomiting.
Prevpac may limit efficacy of live bacterial vaccines. Tell your healthcare provider that you are taking Prevpac prior to any vaccinations.

Before taking a new medication, be sure to consult with your provider on all other medications you are currently on. Drug interactions may change how your medications work or create undesired side effects. Consulting with a medical professional can help limit unwanted side effects or drug interactions that may be very risky or even fatal.
Prevpac is known to interact with the following medications:
- Methotrexate – methotrexate is strong medication taken for treatment of psoriasis or rheumatoid arthritis.
Clarithromycin can slow down the removal of certain medications from your body, potentially affecting how they work. Some products require stomach acid for proper absorption, so lansoprazole may also change how products work.
Before using Prevpac, be sure to keep a list of all the products you use and share it with your doctor or pharmacist so they can determine the right dosage for you. This includes supplements and over-the-counter medications, as they might have active ingredients that interact with the drug. Do not start, stop, or change dosages without consulting a medical professional first.
