Common questions about side effects of dexlansoprazole

Here are answers to some common questions about side effects of dexlansoprazole delayed-release oral capsule. If you have other questions, talk with your doctor or pharmacist.

How do side effects of dexlansoprazole compare with those seen with omeprazole?

Side effects of dexlansoprazole and omeprazole are very similar. Both omeprazole and dexlansoprazole are proton pump inhibitor (PPI) medications prescribed for similar conditions.

Mild side effects of dexlansoprazole and omeprazole include headache, abdominal pain, and diarrhea.

Shared serious side effects include low magnesium blood level, low vitamin B12 blood level, and increased risk for bone fracture. One difference is rare reports of atrophic gastritis in people who used omeprazole long-term. This side effect hasn’t been reported with dexlansoprazole.

Talk with your doctor or pharmacist to learn more about how dexlansoprazole and omeprazole compare.

Does dexlansoprazole cause long-term side effects?

Yes, in some cases dexlansoprazole delayed-release oral capsule may cause long-term side effects. These can occur if you take the drug for a long time or they may last for a while after you’ve stopped taking the drug.

Examples of long-term side effects reported with dexlansoprazole delayed-release oral capsule include:

  • a certain type of nephritis
  • low vitamin B12 blood level
  • a certain type of stomach polyps
  • increased risk for bone fracture*
  • low magnesium blood level*

Talk with your doctor to learn more about these side effects and how to manage them. Ask your doctor for more information about how long these side effects of dexlansoprazole may last.

Side effects of dexlansoprazole in detail

Below you’ll find details on some of the side effects of dexlansoprazole delayed-release oral capsule.

Increased risk for bone fracture

Studies in people taking proton pump inhibitor (PPIs) medications, such as dexlansoprazole, show an increased risk for bone fracture with long-term use. These fractures were reported in the wrist, hip, or spine and are related to osteoporosis.

Symptoms of a bone fracture include:

  • severe pain in the affected bone
  • swelling, bruising, and discoloration at the affected area
  • difficulty or inability to support weight with the affected bone

Certain factors can increase the risk of bone fracture with dexlansoprazole delayed-release oral capsule. These include taking a high dosage and taking the drug for longer than a year. Having osteoporosis also increases this risk.

Ways to manage

To minimize risk of bone fracture, talk with your doctor to ensure:

  • you’re taking the lowest dosage of dexlansoprazole needed to treat your condition
  • you don’t take dexlansoprazole longer than needed to treat your condition and symptoms

Also talk with your doctor about ways to maintain bone health if you take dexlansoprazole. Depending on your risk of fractures, they may suggest using calcium and vitamin D supplements. They can also discuss other strategies for building healthy bones, such as resistance training or eating certain foods.

If you develop symptoms of a bone fracture, seek medical attention right away.

Low magnesium blood level

Low magnesium blood level is a rare side effect that has been reported when proton pump inhibitor (PPI) drugs such as dexlansoprazole are taken long term.

Magnesium is a mineral found throughout your body. It’s needed for many different functions, including sleep, exercise, and making proteins. Symptoms of low blood magnesium include:

  • nausea and vomiting
  • appetite loss
  • weakness
  • muscle cramps or spasms

Serious cases of low blood magnesium are rare, but can cause more serious symptoms such as seizures or arrhythmia.

Without treatment, low blood magnesium can also cause low blood levels of calcium or potassium. If you already have a low blood calcium level, it may be worsened if you develop low blood magnesium from taking dexlansoprazole.

Ways to manage

If you experience symptoms of low blood magnesium, tell your doctor. They’ll likely recommend stopping dexlansoprazole and starting magnesium replacement treatment.

Severe skin reactions

Rarely, severe skin reactions have been reported in people taking proton pump inhibitors (PPIs) including dexlansoprazole. While rare, these reactions are potentially life threatening.

These severe skin reactions include:

If you’ve experienced a severe skin reaction from taking a proton pump inhibitor (PPI) besides dexlansoprazole in the past, let your doctor know before starting treatment. You may be at higher risk of this side effect if you take dexlansoprazole.

Ways to manage

If you experience symptoms of severe skin reactions listed above, immediately seek medical attention. Call 911 or your local emergency number. These reactions are life threatening and require immediate treatment in a hospital or emergency room. Your dexlansoprazole treatment will be stopped should any of these reactions occur.

Allergic reaction

For some people, dexlansoprazole delayed-release oral capsule can cause an allergic reaction.

Symptoms can be mild or serious, and they may include:

  • itchiness
  • skin rash
  • swelling under the skin, usually affecting eyelids, lips, hands, or feet
  • swelling of the mouth, tongue, or throat, which can make it hard to breathe
  • flushing (temporary warmth, redness, or deepening of skin color)

Ways to manage

For mild allergic reaction symptoms, such as a mild rash, call your doctor right away. They may recommend treatments to help manage your symptoms. They’ll also let you know whether you should keep taking the medication.

For severe allergic reaction symptoms, such as swelling or trouble breathing, call 911 or your local emergency number right away. These symptoms require immediate medical care because they can become life threatening. If you’ve had a serious allergic reaction to dexlansoprazole delayed-release oral capsule, your doctor may recommend taking a different medication instead.
