Important warnings
- Severe diarrhea warning: Rabeprazole raises your risk of severe diarrhea. This diarrhea is caused by infection of the intestines by bacteria (Clostridium difficile). Talk to your doctor if you have watery stool, stomach pain, or a fever that doesn’t go away.
- Bone fractures warning: If you take several daily doses of rabeprazole for a long period of time (1 year or longer), your risk of fractures of the hip, wrist, or spine is increased. This drug should be used at the lowest dose possible. It should also be used for the shortest time needed.
- Low magnesium levels warning: Rabeprazole can cause low levels in your body of a mineral called magnesium. This usually happens after 1 year of treatment. However, it can occur after you take rabeprazole for 3 months or longer. Low magnesium levels may not cause any symptoms, but serious side effects can occur. These can include muscle spasms, abnormal heart rhythms, or seizures.
- Cutaneous lupus erythematosus and systemic lupus erythematosus warning: Rabeprazole can cause cutaneous lupus erythematosus (CLE) and systemic lupus erythematosus (SLE). CLE and SLE are autoimmune diseases. Symptoms of CLE can range from a rash on the skin and nose, to a raised, scaly, red or purple rash on certain parts of the body. Symptoms of SLE can include fever, tiredness, weight loss, blood clots, heartburn, and stomach pain. If you have any of these symptoms, call your doctor.
- Fundic gland polyps warning: Long-term use (especially over one year) of rabeprazole can cause fundic gland polyps. These polyps are growths on the lining of your stomach that can become cancerous. To help prevent these polyps, you should use this drug for as short a time as possible.
