Side effects of esomeprazole in detail

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

Bone fractures

People taking esomeprazole delayed-release oral capsule in studies reported bone fractures. This side effect may be serious.

Taking a proton pump inhibitor (PPI) may increase the risk of osteoporosis-related bone fractures. (Esomeprazole delayed-release oral capsule is a PPI). With osteoporosis, your bones become thin and brittle. This makes them more likely to break. Bone fractures of the hip, wrist, or spine may be more likely to happen to people taking a PPI.

Certain factors can increase the risk of bone fractures with esomeprazole delayed-release oral capsule. These include taking high doses of esomeprazole or taking it for a year or longer.

Ways to manage

Due to this risk, doctors usually prescribe esomeprazole delayed-release capsule at the lowest dosage for the shortest period of time necessary. If you take this medication long term or in high doses, your doctor may suggest ways to help support your bone health. For example, they may recommend taking a calcium supplement.

New or worsening lupus

People taking esomeprazole delayed-release oral capsule have reported new or worsening lupus. This side effect may be serious, but it’s unclear how often it has happened or if esomeprazole delayed-release oral capsule was the cause. But it’s important to note that lupus was not seen during studies of esomeprazole delayed-release oral capsule.

Lupus is an autoimmune disorder that can affect the joints and skin. (Autoimmune disorders happen when the immune system attacks the body’s own tissues.) Some people starting a PPI, including esomeprazole, may develop lupus. People who already have lupus may experience worsening symptoms. This can occur from days to years after starting a PPI.

Symptoms may include:

  • fever
  • fatigue
  • joint pain
  • rash on your cheeks

Ways to manage

If you experience new or worsening symptoms of lupus, tell your doctor. They’ll likely recommend stopping esomeprazole delayed-release capsules. In most cases, symptoms improve within a couple of months after stopping the drug.

Severe, watery diarrhea

People taking esomeprazole delayed-release oral capsule have reported severe, watery diarrhea due to C.diff. This side effect may be serious, but it’s unclear how often this has happened or if esomeprazole delayed-release oral capsule was the cause. But it’s important to note that severe, watery diarrhea was not seen during studies of esomeprazole delayed-release oral capsule.

Taking a PPI, such as esomeprazole delayed-release capsule, may increase the risk of severe, watery diarrhea. This kind of diarrhea is due to a bacterial infection with C.diff. Other symptoms may include:

  • appetite loss
  • nausea
  • stomach cramps
  • stomach pain
  • fever

Ways to manage

If you develop symptoms of diarrhea due to C. diff, consult your doctor for advice. If your symptoms seem severe, get medical care right away.

Allergic reaction

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

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

  • itchiness
  • skin rash
  • severe skin rashes that may blister or peel
  • 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

If you experience a mild allergic reaction, 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 esomeprazole delayed-release oral capsule, your doctor may recommend taking a different medication instead.
