Why Are Reactions to Prevacid 24HR a Concern?

Serious Side Effects

Some side effects with Prevacid 24HR, while occurring infrequently, are potentially serious and should be reported immediately to your healthcare provider. These include but are not limited to:
  • Signs of an allergic reaction to Prevacid 24HR, such as:
    • An unexplained rash
    • Hives
    • Itching
    • Unexplained swelling, especially of the mouth, lips, or throat
    • Wheezing or difficulty breathing
    • Difficulty swallowing
  • An irregular heart rhythm (arrhythmia)
  • Chest pain (angina)
  • A slow heart rate (bradycardia)
  • Heart palpitations
  • A heart attack
  • Anxiety or depression
  • Broken bones (some studies suggest this or other similar medications may increase the risk of bone fractures)
  • Signs of low blood magnesium (hypomagnesemia), such as:
    • Muscle spasm
    • An irregular heart rhythm (arrhythmia)
    • Seizures.


It should be noted that these "side effects" occurred rarely in clinical studies, and there is a good chance that they are completely unrelated to Prevacid 24HR. For instance, it is highly unlikely that this medication could cause a heart attack.
