Warnings
Contraindications
Hypersensitivity to pantoprazole or other proton pump inhibitors (PPIs)
Concomitant administration with 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 who have diarrhea that does not improve
Severe hepatic impairment
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
Published observational studies suggest that PPI therapy may be associated with an increased risk for osteoporosis-related fractures of the hip, wrist, or spine, particularly with prolonged (>1 year), 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
PPIs may decrease the efficacy of clopidogrel by reducing the formation of the active metabolite
Therapy increases risk of Salmonella, Campylobacter, and other infections
Infusion related reactions including thrombophlebitis and hypersensitivity reported
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
Relief of symptoms does not eliminate the possibility of a 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
Risk of salmonella and campylobacter infections increased with use of proton pump inhibitors
May elevate and/or prolong serum concentrations of methotrexate and/or its metabolite when administered concomitantly with PPIs, possibly leading to toxicity; consider a temporary withdrawal of PPI therapy with high dose methotrexate administration
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 (eg, 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 (>1 year); adverse effects may result, including tetany, arrhythmias, and seizures; 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 adequate and well-controlled studies in pregnant women; advise pregnant women of the potential risk of fetal harm; drug should be used during pregnancy only if potential benefit justifies potential risk to fetus
Lactation
Pantoprazole and metabolites are excreted in milk of rats. Pantoprazole excretion in human milk has been detected in a study of a single nursing mother after a single 40 mg oral dose of pantoprazole sodium; clinical relevance of this finding not known; many drugs excreted in human milk have potential for serious adverse reactions in nursing infants; based on potential for tumorigenicity shown for pantoprazole sodium in rodent carcinogenicity studies, a decision should be made whether to discontinue nursing or to discontinue drug, taking into account benefit of drug to mother
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

PANTOPRAZOLE - INJECTION
(pan-TOE-pra-zole)
COMMON BRAND NAME(S): Protonix IV
USES: Pantoprazole is used to treat certain stomach and esophagus problems (such as acid reflux). It works by decreasing the amount of acid your stomach makes. This medication relieves symptoms such as heartburn, difficulty swallowing, and cough. It helps heal acid damage to the stomach and esophagus, helps prevent ulcers, and may help prevent cancer of the esophagus. Pantoprazole belongs to a class of drugs known as proton pump inhibitors (PPIs).The injection form of this drug is used for a short time when you cannot take the medication by mouth. When possible, your doctor should switch you to the form that is taken by mouth.
HOW TO USE: This medication is given by injection into a vein as directed by your doctor. The dosage and length of treatment are based on your medical condition and response to treatment.If you are using this medication at home, learn all preparation and usage instructions from your health care professional. Before using, check this product visually for particles or discoloration. If either is present, do not use the liquid. Learn how to store and discard medical supplies safely.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 use this medication.
SIDE EFFECTS: Headache or diarrhea may occur. Redness, pain, or swelling at the injection site may also occur. If any of these effects last or get 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.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 not listed above, 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 using pantoprazole, 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, a lack of certain minerals in the body (such as zinc), 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 pantoprazole) may increase your risk of bone fractures, especially with longer use, higher doses, and in older adults. Talk with your doctor 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.This medication passes into breast milk. Consult your doctor before breast-feeding.
DRUG INTERACTIONS: 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.
