General Information on PrevPac
PrevPac is used for treating stomach or intestinal ulcers caused due to H. pylori bacteria. It also prevents the ulcers from coming back. An ulcer can lead to serious damage to the stomach or intestinal lining, including blockage, tearing or bleeding.
This medicine is a combination of three drugs: Lansoprazole, Clarithromycin and Amoxicillin. Clarithromycin is a macrolide antibiotic, Amoxicillin is a penicillin antibiotic, while Lansoprazole belongs to the class of PPIs or proton pump inhibitors. Antibiotics work by fighting the growth and spread of bacteria. PPIs work by blocking the production of acid in the patient’s stomach.
You can buy PrevPac in the form of oral capsules and tablets.
Side effects of PrevPac
Before you buy PrevPac, inform your doctor if you have an allergy to Lansoprazole, Clarithromycin or Amoxicillin, or to macrolide antibiotics (e.g. erythromycin), cephalosporins (e.g. cephalexin) or penicillin (e.g. ampicillin). If you are allergic to any of these ingredients, you may witness allergy symptoms. Such symptoms include hives, difficulty breathing, severe dizziness, or facial swelling.
