Aciphex (rabeprazole sodium) is a proton pump inhibitor (PPI) designed to provide long-lasting suppression of gastric acid production. It is clinically proven to treat gastroesophageal reflux disease (GERD), heal erosive esophagitis, and manage conditions related to hypersecretion. By targeting the proton pumps in the stomach lining, Aciphex offers sustained symptomatic relief and promotes mucosal healing. Its delayed-release formulation ensures optimal delivery and efficacy, making it a trusted choice among gastroenterologists and primary care providers.

- Supports improved quality of life through reliable symptom control
- Offers convenient dosing with minimal interference to daily routine
Common use
Aciphex is primarily indicated for the short-term treatment (4 to 8 weeks) in healing and symptomatic relief of erosive gastroesophageal reflux disease (GERD). It is also approved for maintenance therapy of healed erosive esophagitis and treatment of symptomatic GERD. Additionally, Aciphex is used in combination with antibiotics for the eradication of Helicobacter pylori in patients with duodenal ulcer disease. Off-label uses may include management of Zollinger-Ellison syndrome and other hypersecretory conditions, though such applications require careful medical supervision.
Dosage and direction
The recommended adult dosage for healing of erosive GERD is 20 mg once daily for 4 to 8 weeks. For maintenance of healing of erosive esophagitis, the dose is 20 mg once daily. For symptomatic GERD, 20 mg once daily for 4 weeks is recommended. For H. pylori eradication, Aciphex 20 mg is taken twice daily for 7 days alongside prescribed antibiotics. Tablets should be swallowed whole, with or without food, and must not be crushed, split, or chewed. Dosage adjustments may be necessary for patients with severe hepatic impairment.
Precautions
Patients should be advised that Aciphex may mask symptoms of gastric malignancy; appropriate diagnostic evaluation should be conducted if alarm features such as unintentional weight loss, recurrent vomiting, or dysphagia are present. Long-term use (particularly beyond one year) may be associated with an increased risk of fractures of the hip, wrist, and spine. Hypomagnesemia has been reported rarely with prolonged PPI therapy; monitoring of magnesium levels should be considered in patients expected to be on long-term treatment or those taking concomitant medications such as digoxin or diuretics. Patients should be monitored for signs of Clostridium difficile-associated diarrhea.
Contraindications
Aciphex is contraindicated in patients with known hypersensitivity to rabeprazole, substituted benzimidazoles, or any component of the formulation. Concomitant use with rilpivirine-containing products is contraindicated due to the potential for decreased rilpivirine plasma concentrations, which may result in loss of virologic response and possible resistance. Use is also contraindicated in settings where rapid and complete acid suppression may be theoretically harmful, such as in patients with suspected gastrointestinal obstruction or perforation.
Possible side effect
Common adverse reactions (≥2% incidence) include headache, diarrhea, nausea, vomiting, abdominal pain, flatulence, and constipation. Less frequently, patients may experience dizziness, rash, dry mouth, insomnia, or back pain. Serious but rare side effects include anaphylaxis, Stevens-Johnson syndrome, toxic epidermal necrolysis, acute interstitial nephritis, hepatic encephalopathy in patients with pre-existing liver disease, and cutaneous lupus erythematosus. Vitamin B12 deficiency may occur with long-term use due to decreased absorption.
Drug interaction
Aciphex may alter the absorption of drugs that are pH-dependent, such as ketoconazole, iron salts, and digoxin (monitoring recommended). It may increase exposure to methotrexate, potentially leading to toxicity. Concomitant use with warfarin may require increased monitoring of INR due to potential increases in international normalized ratio (INR) and prothrombin time. Rabeprazole is metabolized by CYP2C19 and CYP3A4; caution is advised with drugs that are substrates or inhibitors of these enzymes. Avoid concomitant use with atazanavir and nelfinavir due to reduced antiretroviral efficacy.
Missed dose
If a dose of Aciphex is missed, it should be taken as soon as remembered, unless it is nearly time for the next scheduled dose. In that case, the missed dose should be skipped and the regular dosing schedule resumed. Patients should not take a double dose to make up for a missed one. Consistency in daily dosing is recommended to maintain acid suppression, though occasional missed doses are unlikely to significantly impact long-term efficacy.
Overdose
Experience with Aciphex overdose is limited. Reported doses of up to 80 mg have been well-tolerated. Rabeprazole is not removed by hemodialysis. In the event of suspected overdose, supportive and symptomatic treatment is recommended. Gastric lavage may be considered if performed shortly after ingestion. Monitor for potential electrolyte abnormalities, particularly in patients with comorbid conditions. There is no specific antidote for rabeprazole overdose.
Storage
Aciphex tablets should be stored at room temperature, between 20°C to 25°C (68°F to 77°F), with excursions permitted between 15°C to 30°C (59°F to 86°F). Keep the medication in its original container, tightly closed, and protected from moisture and light. Keep out of reach of children and pets. Do not use beyond the expiration date printed on the packaging.

The full prescribing information should be reviewed for complete details on warnings, precautions, and adverse reactions.
Reviews
Clinical studies and post-marketing surveillance demonstrate that Aciphex is generally well-tolerated and effective for its indicated uses. In randomized controlled trials, Aciphex 20 mg daily showed healing rates of up to 93% in patients with erosive esophagitis over an 8-week period. Patients report significant improvement in heartburn frequency and severity, with many experiencing relief within the first few days of therapy. Long-term users note consistent symptom control, though some express concern regarding potential side effects with extended use. Healthcare providers appreciate its reliable pharmacokinetic profile and favorable drug interaction spectrum compared to some other PPIs.
