Pantoprazole (Protonix) is a proton-pump inhibitor (PPI). It's used to treat symptoms of gastroesophageal reflux disease (GERD) in adults and children. It's also used to treat other conditions involving too much stomach acid, such as erosive esophagitis, in adults only. Pantoprazole (Protonix) is taken by mouth, typically once daily for most conditions. Some of the more common side effects of this medication include headache and diarrhea. Pantoprazole (Protonix) isn't available over-the-counter (OTC).
Short-term treatment of gastroesophageal reflux disease (GERD)
Other medical conditions that cause too much stomach acid (e.g., Zollinger-Ellison syndrome)
Pantoprazole (Protonix) 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.

Long-term use might weaken bones and raise the risk of bone fractures

Not available over-the-counter
Swallow the pantoprazole (Protonix) oral tablets whole. Don't chew or crush the tablets. Doing so can change how the medication gets absorbed into your body.
Typically, pantoprazole (Protonix) oral tablets can be taken with or without food. But pantoprazole (Protonix) oral granules and suspension should be taken 30 minutes before your meal.
Pantoprazole (Protonix) oral granules or suspension: Mix and stir the granules or suspension with 5 mL of applesauce. Take the entire dose within 10 minutes of mixing. Make sure to wash down the granules with water. Alternatively, you can mix the granules or suspension with 5 mL of apple juice. Make sure to drink the entire dose immediately. Rinse the cup 1 to 2 more times with apple juice to get all the remaining granules.
Pantoprazole (Protonix) can interact with many medications. Let your care team know what medications you take or plan to take. These medications include over-the-counter products and supplements. Talk with your care team if you have any questions about interactions with this medication.
Pantoprazole (Protonix) 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 heartburn can be a symptom of stomach cancer. If your heartburn gets worse or comes back after taking pantoprazole (Protonix), let your healthcare professional (HCP) know. Also contact your HCP if you have poor appetite, unexplained weight loss, or weakness along with your heartburn. They can check if there are other serious medical problems going on.
Some people taking PPIs like pantoprazole (Protonix) have had sudden kidney problems. These problems can happen at any point during treatment. Talk with your HCP if you're urinating more or less than usual, feel nauseous or weak, or have a fever, rash, or joint pain. These can be symptoms of kidney problems.
Risk factors: Older people | Recent stay at a hospital or nursing home | People with a weakened immune system (e.g., HIV, cancer)
Some clinical studies showed that PPIs, such as pantoprazole (Protonix), can raise the risk of getting a bacterial infection called Clostridioides difficile (C. diff). This infection can cause severe 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 C. diff diarrhea, take the lowest possible dose of pantoprazole (Protonix) 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 primary care provider know right away.
Risk factors: Taking high doses of pantoprazole (Protonix) | Taking pantoprazole (Protonix) for longer than a year | Risk for osteoporosis
PPIs like pantoprazole (Protonix) 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 pantoprazole (Protonix) per day or if you take it for more than a year. To prevent the risk of bone fractures, take the lowest possible dose of pantoprazole (Protonix) 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 pantoprazole (Protonix), 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 pantoprazole (Protonix) developed new or worsening lupus, a condition where your immune system attacks your own body. Lupus symptoms can occur any time during treatment with pantoprazole (Protonix). 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 pantoprazole (Protonix), stop the medication and contact your provider.
Risk factor: Long-term use | Taking medications that can lower magnesium levels
Using acid-lowering medications like pantoprazole (Protonix) for a long period of time can cause your vitamin B12 levels to drop. Pantoprazole (Protonix) lowers the amount of acid in your stomach, which is needed for vitamin B12 absorption. If you've been taking this medication for longer than 3 years, or if you have symptoms of vitamin B12 deficiency (e.g., dizziness, muscle weakness, pale skin, tiredness, tingling in arms or legs), talk to your primary care provider.
Taking pantoprazole (Protonix) can also lower your magnesium levels. This can happen 3 months after taking pantoprazole (Protonix), but it's more likely after a year of treatment. Low magnesium levels can sometimes lead to other electrolyte problems. You're at risk for low magnesium levels if you take other medications that can affect electrolyte levels, such as digoxin (Lanoxin) or water pills. Your primary care provider might check your blood during treatment with pantoprazole (Protonix) to make sure your electrolyte levels are in the normal range. Watch for symptoms of electrolyte problems like irregular heart rate, muscle cramps, and tremors. Let your primary care provider know right away if they occur.
Pantoprazole (Protonix) can interfere with how other medications work. An important interaction to note is with pantoprazole (Protonix) is Edurant (rilpivirine), a medication that treat human immunodeficiency virus (HIV). Pantoprazole (Protonix) can lower the amount of Edurant (rilpivirine) in your body and cause the medication to not work as well, which can lead to virus spreading in your body. Make sure to avoid taking these medications together.
In addition, pantoprazole (Protonix) 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, pantoprazole (Protonix) can raise the risk of methotrexate toxicity when taken together with methotrexate.
Pantoprazole (Protonix) can get in the way of certain tumor screenings or drug testing, which can lead to inaccurate results. Talk with your HCP or radiologist about your medication history before getting any testing done. In some cases, your care team might ask you to temporarily stop pantoprazole (Protonix) 2 weeks before your blood work.
Pantoprazole (Protonix) is available by prescription as oral tablets, suspension, and granules. It's also available as an injection that's administered into the veins by a provider in a healthcare setting.
