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.

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.

This includes supplements and over-the-counter medications, as they might have active ingredients that interact with the drug.
