Warnings
Contraindications
Hypersensitivity to rabeprazole or other proton pump inhibitors (PPIs)
Rilpivirine-containing products
Cautions
PPIs are possibly associated with increased incidence of Clostridium difficile-associated diarrhea (CDAD); consider diagnosis of CDAD for patients taking PPIs with diarrhea that does not improve
In liver disease may require dosage reduction
Cutaneous lupus erythematosus (CLE) and systemic lupus erythematosus (SLE) reported with PPIs; avoid using for longer than medically indicated; discontinue if signs or symptoms consistent with CLE or SLE are observed and refer patient to specialist; most patients improve with discontinuation of PPI alone in 4-12 weeks; serological testing (e.g. ANA) may be positive and elevated serological test results may take longer to resolve than clinical manifestations
Severe cutaneous adverse reactions, including Stevens-Johnson syndrome (SJS) and toxic epidermal necrolysis (TEN), drug reaction with eosinophilia and systemic symptoms (DRESS), and acute generalized exanthematous pustulosis (AGEP) reported in association with use of PPIs; discontinue therapy at first signs or symptoms of severe cutaneous adverse reactions or other signs of hypersensitivity and consider further evaluation
Use of proton pump inhibitors may increase risk of salmonella and campylobacter infection
Reduce of symptoms does not eliminate presence of gastric malignancy; consider additional follow-up and diagnostic testing in adult patients who have suboptimal response or early symptomatic relapse after completing treatment with a PPI
Published observational studies suggest that PPI therapy may be associated with an increased risk of osteoporosis-related fractures of the hip, wrist, or spine; particularly with prolonged (>1 yr), high-dose therapy
Decreased gastric acidity increases serum chromogranin A (CgA) levels and may cause false positive diagnostic results for neuroendocrine tumors; temporarily discontinue PPIs before assessing CgA levels
Monitor for increases in INR and prothombin time when coadministered with warfarin
Daily long-term use (e.g., longer than 3 years) may lead to malabsorption or a deficiency of cyanocobalamin
Acute interstitial nephritis reported in patients taking proton pump inhibitors
Concomitant use of proton pump inhibitors with methotrexate, primarily at high dose, may elevate and prolong serum concentrations of methotrexate and/or its metabolite, possibly leading to methotrexate toxicities; in high-dose methotrexate administration, a temporary withdrawal of the PPI may be considered in some patients
PPI therapy is associated with increased risk of fundic gland polyp; risk increases with long-term use >1 year; patient may be asymptomatic; problem usually identified incidentally on endoscopy; use shortest duration of therapy appropriate to condition being treated
Acute tubulointerstitial nephritis (TIN) reported in patients taking PPIs; may occur at any point during PPI therapy; patients may present with varying signs and symptoms from symptomatic hypersensitivity reactions to non-specific symptoms of decreased renal function (e.g., malaise, nausea, anorexia); in reported case series, some patients were diagnosed on biopsy and in absence of extra-renal manifestations (eg, fever, rash or arthralgia); discontinue therapy and evaluate patients with suspected acute TIN
Hypomagnesemia and mineral metabolism
- Hypomagnesemia may occur with prolonged use (ie, >1 yr); adverse effects, such as tetany, arrhythmias, or seizures, may result; in 25% of cases reviewed, magnesium supplementation alone did not improve low serum magnesium levels, and the PPI had to be discontinued; consider monitoring magnesium levels prior to initiation of PPI treatment and periodically
- Hypomagnesemia may lead to hypocalcemia and/or hypokalemia and may exacerbate underlying hypocalcemia in at-risk patients; in most patients, treatment of hypomagnesemia required magnesium replacement and discontinuation of the PPI
- Consider monitoring magnesium and calcium levels prior to initiation of therapy and periodically while on treatment in patients with a preexisting risk of hypocalcemia (eg, hypoparathyroidism); supplement with magnesium and/or calcium as necessary. If hypocalcemia is refractory to treatment, consider discontinuing the PPI
Pregnancy & Lactation
Pregnancy
There are no available human data in pregnant women to inform drug associated risk; background risk of major birth defects and miscarriage for indicated populations are unknown; however, background risk in U.S. general population of major birth defects is 2-4% and of miscarriage is 15- 20% of clinically recognized pregnancies; no evidence of adverse developmental effects were seen in animal reproduction studies with rabeprazole administered during organogenesis at 13 and 8 times human area under plasma concentration-time curve (AUC) at recommended dose for GERD, in rats and rabbits, respectively; changes in bone morphology were observed in offspring of rats treated with oral doses of different PPI through most of pregnancy and lactation; when maternal administration was confined to gestation only, there were no effects on bone physeal morphology in offspring at any age
Lactation
Lactation studies have not been conducted to assess presence in human milk, effects on breastfed infant, or effects on milk production; drug is present in rat milk; development and health benefits of breastfeeding should be considered along with mother’s clinical need for therapy and any potential adverse effects on breastfed infant from drug or from underlying maternal condition
Pregnancy Categories
A: Generally acceptable. Controlled studies in pregnant women show no evidence of fetal risk.
B: May be acceptable. Either animal studies show no risk but human studies not available or animal studies showed minor risks and human studies done and showed no risk. C: Use with caution if benefits outweigh risks. Animal studies show risk and human studies not available or neither animal nor human studies done. D: Use in LIFE-THREATENING emergencies when no safer drug available. Positive evidence of human fetal risk. X: Do not use in pregnancy. Risks involved outweigh potential benefits. Safer alternatives exist. NA: Information not available.Pharmacology

RABEPRAZOLE DELAYED-RELEASE - ORAL
(ra-BEP-ra-zole)
COMMON BRAND NAME(S): Aciphex
USES: Rabeprazole is used to treat certain stomach and esophagus problems (such as acid reflux, ulcers). It works by decreasing the amount of acid your stomach makes. It relieves symptoms such as heartburn, difficulty swallowing, and cough. This medication helps heal acid damage to the stomach and esophagus, helps prevent ulcers, and may help prevent cancer of the esophagus. Rabeprazole belongs to a class of drugs known as proton pump inhibitors (PPIs).
HOW TO USE: Read the Medication Guide and the Patient Information Leaflet if available from your pharmacist before you start taking rabeprazole and each time you get a refill. If you have any questions, ask your doctor or pharmacist.If you are using the tablets, take your dose by mouth with or without food as directed by your doctor, usually 1 to 2 times daily. Swallow the tablet whole with water. Do not crush, chew, or split the tablet. Doing so can release all of the drug at once, increasing the risk of side effects.If you are using the capsules, take the dose 30 minutes before a meal as directed by your doctor, usually once daily. Do not swallow the capsule whole. Open the capsule and sprinkle the contents onto a small amount of soft food (such as applesauce or yogurt) or liquid. The food or liquid that you use should be at or below room temperature. Swallow the entire mixture within 15 minutes of preparing it. Do not chew or crush the prepared mixture.The dosage and length of treatment are based on your medical condition and response to treatment. In children, the dosage is also based on weight.If needed, antacids may be taken along with this medication. If you are also taking sucralfate, take rabeprazole at least 30 minutes before sucralfate.Use this medication regularly to get the most benefit from it. To help you remember, take it at the same time(s) each day. Continue to take this medication for the prescribed length of treatment even if you are feeling better.Tell your doctor if your condition lasts or gets worse. The risk of side effects goes up over time. Ask your doctor how long you should take this medication.
SIDE EFFECTS: Headache may occur. If this effect lasts or gets worse, tell your doctor or pharmacist promptly.Remember that this medication has been prescribed because your doctor 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.Tell your doctor right away if you have any serious side effects, including: symptoms of a low magnesium blood level (such as muscle spasms, irregular heartbeat, seizures), signs of lupus (such as rash on nose and cheeks, new or worsening joint pain).This medication may rarely cause a severe intestinal condition due to a bacteria called C. difficile. This condition may occur during treatment or weeks to months after treatment has stopped. Tell your doctor right away if you develop: diarrhea that doesn't stop, abdominal or stomach pain/cramping, blood/mucus in your stool.If you have these symptoms, do not use anti-diarrhea or opioid products because they may make symptoms worse.Rarely, proton pump inhibitors (such as rabeprazole) have caused vitamin B-12 deficiency. The risk is increased if they are taken every day for a long time (3 years or longer). Tell your doctor right away if you develop symptoms of vitamin B-12 deficiency (such as unusual weakness, sore tongue, or numbness/tingling of the hands/feet).A very serious allergic reaction to this drug is rare. However, get medical help right away if you notice any symptoms of a serious allergic reaction, including: fever, swollen lymph nodes, rash, itching/swelling (especially of the face/tongue/throat), severe dizziness, trouble breathing, signs of kidney problems (such as change in the amount of urine).This is not a complete list of possible side effects. If you notice other effects, contact your doctor or pharmacist.In the US -Call your doctor for medical advice about side effects. You may report side effects to FDA at 1-800-FDA-1088 or at www.fda.gov/medwatch.In Canada - Call your doctor for medical advice about side effects. You may report side effects to Health Canada at 1-866-234-2345.
PRECAUTIONS: Before taking rabeprazole, tell your doctor or pharmacist if you are allergic to it; or to similar drugs (such as lansoprazole, omeprazole); 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, lupus.Some symptoms may actually be signs of a more serious condition. Get medical help right away if you have: heartburn with lightheadedness/sweating/dizziness, chest/jaw/arm/shoulder pain (especially with shortness of breath, unusual sweating), unexplained weight loss.Before having surgery, tell your doctor or dentist about all the products you use (including prescription drugs, nonprescription drugs, and herbal products).Proton pump inhibitors (such as rabeprazole) may increase your risk for bone fractures, especially with longer use, higher doses, and in older adults. Talk with your doctor or pharmacist about ways to prevent bone loss/fracture, such as by taking calcium (such as calcium citrate) and vitamin D supplements.Older adults may be more sensitive to the side effects of this drug, especially bone loss and fractures (see above), and C. difficile infection (see Side Effects section).During pregnancy, this medication should be used only when clearly needed. Discuss the risks and benefits with your doctor.It is unknown if this medication passes into breast milk. However, similar drugs pass into breast milk. The effects on a nursing infant are unknown. Consult your doctor before breast-feeding.
DRUG INTERACTIONS: See also How to Use section.Drug interactions may change how your medications work or increase your risk for serious side effects. This document does not contain all possible drug interactions. Keep a list of all the products you use (including prescription/nonprescription drugs and herbal products) and share it with your doctor and pharmacist. Do not start, stop, or change the dosage of any medicines without your doctor's approval.A product that may interact with this drug is: methotrexate (especially high-dose treatment).Some products need stomach acid so that the body can absorb them properly. Rabeprazole decreases stomach acid, so it may change how well these products work. Some affected products include ampicillin, atazanavir, erlotinib, levoketoconazole, nelfinavir, pazopanib, rilpivirine, certain azole antifungals (itraconazole, ketoconazole, posaconazole), among others.This medication may interfere with certain laboratory tests, possibly causing false test results.
