In general, pantoprazole (the active ingredient contained in Protonix IV) has been very well tolerated. At the time of its approval by the FDA, pantoprazole had been tested in over 11,100 patients in clinical trials involving various dosages and duration of treatment. In 2 controlled trials where daily doses up to 40 mg were given for up to 8 weeks, there were no dose-related adverse side effects associated with the use of this drug.
Gastrointestinal side effects may be due to underlying diseases among treated patients. In placebo-controlled trials, the use of pantoprazole (the active ingredient contained in Protonix IV) was associated with the following (incidence vs. placebo): diarrhea (4% vs. 1%), flatulence (2% vs. 2%), abdominal pain (1% vs. 2%), and eructation (belching) (1% vs. 1%). Postmarketing side effects have included cases of pancreatitis and clostridium difficile associated diarrhea.
In addition, the following gastrointestinal problems have been reported in up to 1% of patients (causal relationship is unclear): constipation, dyspepsia, gastroenteritis, nausea, vomiting, anorexia, aphthous stomatitis, cardiospasm, colitis, dry mouth, duodenitis, dysphagia, esophageal hemorrhage, esophagitis, gastrointestinal carcinoma, gastrointestinal hemorrhage, gastrointestinal moniliasis, gingivitis, glossitis, halitosis, hematemesis, increased appetite, increased salivation, melena, mouth ulceration, oral moniliasis, periodontal abscess, periodontitis, rectal hemorrhage, stomach ulcer, tongue discoloration, abnormal stools, hernia, and ulcerative colitis.
Nervous system side effects have included headache in 6% and insomnia in less than 1% of patients (compared to 6% and 2% of placebo patients, respectively) in controlled trials. Less common nervous system side effects that have occurred in approximately 1% of patients and where there is an unclear causal association include asthenia, pain, migraine, anxiety, dizziness, abnormal dreams, confusion, convulsion, depression, dysarthria, emotional lability, hallucinations, hyperkinesia, hypesthesia, libido decreased, nervousness, neuralgia, neuritis, paresthesia, reflexes decreased, malaise, fatigue, sleep disorder, somnolence, thinking abnormal, tremor, vertigo, speech disorder, deafness, ear pain, taste perversion, hypokinesia, or tinnitus.

The risk of hip fracture was significantly increased among patients prescribed long-term high dose PPIs.
Hypersensitivity side effects have been rare. Allergic reactions, usually manifest as a rash, have appeared in less than 1% of patients. Other possible signs of allergy have included facial and generalized edema. Rare cases of anaphylaxis, angioedema, and severe dermatologic reactions (Stevens-Johnson syndrome, toxic epidermal necrolysis--some fatal--and erythema multiforme) have been described in postmarketing reports.
