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.
Also inform your doctor if you have a liver or kidney disease, muscle disease, or a viral infection such as infectious mononucleosis. Seek medical attention immediately if you have any of the following symptoms:
- Heartburn along with lightheadedness, dizziness or sweating
- Chest pain
- Shoulder or jaw pain along with trouble breathing
- Unexplained weight loss
- Pain spreading to the neck, shoulders or arms
Clarithromycin in PrevPac may sometimes lead to QT prolongation, which may result in fatally fast or irregular heartbeat. Inform your doctor beforehand if you have a family history of heart problems such as sudden cardiac death or QT prolongation, or if you have a heart problem such as heart failure or slow heartbeat.
PrevPac patients may commonly experience an abnormal taste in the mouth, vomiting, nausea, headache or diarrhea. These are mild side effects of the drug and can be easily managed with or without medical help. However, you should notify your doctor immediately if any of these become too troublesome.

What is a "Generic" medication/drug?
Generic drugs are medications that have the comparable medicinal ingredients as the original brand name drug, but which are generally cheaper in price. Nearly 1 in 3 drugs dispensed are "generic". They undergo comparative testing to ensure that they are the same as their "brand" counterparts in:
- Active Ingredient (e.g. "Pravastatin" is the active ingredient in brand name Pravachol)
- Dosage (e.g. 10 mg of the active ingredient)
- Safety (e.g. same or similar side effects, drug interactions)
- Performance (e.g. 10 mg of a "generic" can be substituted for 10 mg of the "brand" and have the same therapeutic result)
- Intended use (e.g. both "generic" and "brand" would be prescribed for the same conditions)
What this means is that "generic" medications can be used as a substitute of their brand equivalents with comparable therapeutic results. There are a few exceptions (examples are outlined at the end of this page) and as always you should consult your physician before switching from a brand name medications to a generic or vice versa.
What differences are there between generic and brand?
While generics and brand equivalent drugs contain comparable active ingredients, they may be different in the following ways:
- Appearance (e.g. the scoring or markings)
The color, shape and size of the medication come from the fillers that are added to the active ingredients to make the drug. These fillers that are added to the drug have no medical use and do not to change the effectiveness of the final product. A generic drug must contain comparable active ingredients and must be comparable in strength and dosage to the original brand name equivalent. Generic drugs can be more cost effective than purchasing the brand name.
Why do generics cost less than the brand name equivalents?
When a new drug is "invented", the company that discovered it has a patent on it that gives them the exclusive production rights for this medication. Once the patent expires in a country, other companies can bring the product to market under their own name. This patent prevents other companies from copying the drug during that time so they can earn back their Research and Development costs through being the exclusive supplier of the product. After the patent expires however, other companies can develop a "generic" version of the product. These versions generally are offered at much lower prices because the companies do not have the same development costs as the original company who developed the medication.
The main thing to realize here though is that the two products are therapeutically comparable. They may look different, and be called something different, but they are required to be have the same active ingredient.
How are Generic drugs tested to ensure quality and efficacy?
The two most generally accepted methods to prove the safety of a generic version of a drug are to either repeat most of the chemistry, animal and human studies originally done, or to show that the drug performs comparably with the original brand name drug. This second option is called a "comparative bioavailability" study. During this type of study, volunteers are given the original drug, and then separately later the generic drug. The rates at which the drug is delivered to the patient (into their blood stream or otherwise absorbed) are measured to ensure they are the same. Because the same active ingredient is used the major concern is just that it delivers the common chemical(s) at the same rate so that they have the same effect. Please note that the methods that the manufacturers use may vary from country to country.
