Rabeprazole (Aciphex) is a medication used to treat symptoms of gastroesophageal reflux disease (GERD) and other conditions involving too much stomach acid. The dosage is typically once a day for most conditions. Rabeprazole (Aciphex) isn't know to cause many side effects, but some of the more common ones include constipation and passing gas. Long-term use of rabeprazole (Aciphex) raise the risk for more serious warnings, such as the risk of bone fractures.
For adults only:
Lower the risk of duodenal ulcer(s) caused by Helicobacter pylori (H. pylori) infection
Other medical conditions that cause too much stomach acid (e.g., Zollinger-Ellison syndrome)
For adults and children 12 years and older:
Gastroesophageal reflux disease (GERD)
Rabeprazole (Aciphex) is a proton pump inhibitor (PPI). It lowers the amount of acid in your stomach by blocking the final step of stomach acid production. This helps relieve heartburn and other stomach problems.

Typically, rabeprazole (Aciphex) can be taken with or without food. But if you're taking this medication to treat H. pylori or duodenal ulcers, it's best to take it with food.
For the treatment of duodenal ulcers, take rabeprazole (Aciphex) in the morning after breakfast. For H. pylori therapy, take your first dose with breakfast and your second dose with dinner. Ask your provider or pharmacist if you have questions about the best time to take rabeprazole (Aciphex).
Swallow the rabeprazole (Aciphex) pills whole. Don't chew or crush the pills. Doing so can change how the medication gets absorbed into your body.
Rabeprazole (Aciphex) can interact with many medications. Let your provider or pharmacist know what medications you take or plan to take. These medications include over-the-counter products and supplements. Talk with your provider or pharmacist if you have any questions about interactions with this medication.
Rabeprazole (Aciphex) can cause some serious health issues. This risk may be even higher for certain groups. If this worries you, talk to your doctor or pharmacist about other options.
Frequent episodes of GERD can sometimes be a symptom of stomach cancer. If your symptoms of GERD get worse or come back after taking rabeprazole (Aciphex), let your provider know. Also contact your provider if you have poor appetite, unexplained weight loss, or weakness along with GERD. They can check if there are other serious medical problems going on.
Some people taking PPIs have developed sudden kidney inflammation. Though rare, this problem can happen at any point during treatment. Talk with your provider if you are urinating more or less than usual, feel nauseous or weak, or have a fever, rash, or joint pain.
Risk factors: Older adults | Recent stay at a hospital or nursing home | People with a weakened immune system
Some clinical studies showed that taking PPIs, such as rabeprazole (Aciphex), can raise the risk of infectious diarrhea. Your risk is higher if you're over 65 years old, have recently stayed at a hospital or nursing home, or have a weakened immune system. To lower your risk of infectious diarrhea, take the lowest possible dose of rabeprazole (Aciphex) for the shortest amount of time that works well for you. If you experience severe or watery diarrhea, fever, belly pain, loss of appetite, or nausea, let your provider know right away.
Risk factors: Taking high doses of rabeprazole (Aciphex) | Taking rabeprazole (Aciphex) for longer than a year | Risk for osteoporosis
PPIs, like rabeprazole (Aciphex), might raise the risk of bone fractures in the hip, wrist, or spine. Your risk is higher if you take more than one dose of rabeprazole (Aciphex) per day or if you take it for more than a year. To prevent the risk of bone fracture, take the lowest possible dose of rabeprazole (Aciphex) for the shortest amount of time for your symptoms. If you've had bone fractures before or have osteoporosis (weak bones), talk to your provider about your risk before using this medication.
PPIs, such as rabeprazole (Aciphex), have rarely caused serious skin reactions. These reactions include Stevens-Johnson syndrome (SJS) and toxic epidermal necrolysis (TEN). Symptoms can include fever, body aches, rash, peeling skin, painful blisters, and swelling of the face. If you notice any of these symptoms, get medical help immediately.
Some people taking PPIs like rabeprazole (Aciphex) developed new or worsening lupus, a condition where your immune system attacks your own body. Lupus symptoms can occur any time during treatment with rabeprazole (Aciphex). Some typical symptoms include joint pain or rash, but they often improve within 1 to 3 months of stopping this medication. If you experience any lupus symptoms while taking rabeprazole (Aciphex), stop the medication and contact your provider.
Taking acid-lowering medications like rabeprazole (Aciphex) for 3 years or longer can lead to poor vitamin B12 absorption. Talk to your provider if you've symptoms of vitamin B12 deficiency, such as dizziness, muscle weakness, pale skin, tiredness, or tingling in arms or legs.
Taking rabeprazole (Aciphex) for 3 months or longer can raise your risk for low magnesium levels, which can sometimes lead to other electrolyte problems. Your risk is higher if you're also taking other medications that can affect electrolyte levels, such as digoxin (Lanoxin) or [water pills]. Let your provider know if you've symptoms electrolyte problems like irregular heart rate, muscle cramps, and tremors.
Rabeprazole (Aciphex) can interfere with how other medications work. An important medication to avoid with rabeprazole (Aciphex) is Edurant (rilpivirine). This is because rabeprazole (Aciphex) can lower the amount of Edurant (rilpivirine) in your body and cause the medication to not work as well, which can lead to human immunodeficiency virus (HIV) spreading in your body. Make sure to avoid taking these medications together.
In addition, rabeprazole (Aciphex) can also interact with warfarin (Coumadin), which can raise your risk of abnormal bleeding. Your provider will monitor your bloodwork (e.g., INR) to make sure these medications are safe to take together. Watch out for nosebleeds, dizziness, unusual bruising, or bleeding from cuts that take a long time to stop.
Finally, rabeprazole (Aciphex) can raise the risk of methotrexate toxicity when taken together with methotrexate.
