Prevpac Oral Precautions
Before taking this product, tell your doctor or pharmacist if you are allergic to lansoprazole, amoxicillin, or clarithromycin; or to penicillins (such as ampicillin), cephalosporins (such as cephalexin), or macrolide antibiotics (such as erythromycin); or if you have any other allergies. This product may contain inactive ingredients, which can cause allergic reactions or other problems. Talk to your pharmacist for more details.
Before using this medication, tell your doctor or pharmacist your medical history, especially of:
- liver disease (including liver problems with past clarithromycin use)
- kidney disease
- a certain type of muscle disease (myasthenia gravis)
- a certain type of viral infection (infectious mononucleosis)
Some symptoms may actually be signs of a more serious condition. Tell your doctor immediately if you have:
- heartburn combined with lightheadedness/sweating/dizziness
- chest pain or shoulder/jaw pain (especially with trouble breathing)
- pain spreading to arms/neck/shoulders
- unexplained weight loss
Clarithromycin may cause a condition that affects the heart rhythm (QT prolongation). QT prolongation can infrequently result in serious (rarely fatal) fast/irregular heartbeat and other symptoms (such as severe dizziness, fainting) that require immediate medical attention. The risk of QT prolongation may be increased if you have certain medical conditions or are taking other drugs that may affect the heart rhythm (see also Drug Interactions section). Before using this product, tell your doctor or pharmacist if you have any of the following conditions:
- certain heart problems (heart failure, slow heartbeat, QT prolongation in the EKG)
- family history of certain heart problems (QT prolongation in the EKG, sudden cardiac death)
Low levels of potassium or magnesium in the blood may also increase your risk of QT prolongation. This risk may increase if you use certain drugs (such as diuretics/"water pills") or if you have conditions such as severe sweating, diarrhea, or vomiting. Talk to your doctor about using this product safely.
During pregnancy, this product should be used only when clearly needed. Discuss the risks and benefits with your doctor.
Amoxicillin passes into breast milk. It is unknown if lansoprazole or clarithromycin pass into breast milk. Consult your doctor before breast-feeding.
Prevpac Oral Side Effects
Diarrhea, headache, nausea, vomiting, and abnormal taste may occur. If any of these effects persist or worsen, tell your doctor or pharmacist promptly.
Remember that your doctor has prescribed this medication because he or she has judged that the benefit to you is greater than the risk of side effects. Many people using this medication do not have serious side effects.

This medication may rarely cause a severe intestinal condition (Clostridium difficile-associated diarrhea) due to a type of resistant bacteria. This condition may occur during treatment or weeks to months after treatment has stopped. Do not use anti-diarrhea products or narcotic pain medications if you have any of the following symptoms because these products may make them worse. Tell your doctor immediately if you develop:
- persistent diarrhea
- abdominal or stomach pain/cramping
- blood/mucus in your stool
Use of this medication for prolonged or repeated periods may result in oral thrush or a new yeast infection. Contact your doctor if you notice white patches in your mouth, a change in vaginal discharge, or other new symptoms.
A very serious allergic reaction to this drug is rare. However, seek immediate medical attention if you notice any symptoms of a serious allergic reaction, including:
- rash
- itching/swelling (especially of the face/tongue/throat)
- severe dizziness
- trouble breathing
Amoxicillin can commonly cause a mild rash that is usually not serious. However, you may not be able to tell it apart from a rare rash that could be a sign of a severe allergic reaction. Therefore, seek immediate medical attention if you develop any rash.
