What are the side effects of Havrix?


In rare cases, Havrix may cause a severe allergic reaction that leads to difficulty breathing, swelling in the face or throat, unusual hoarseness and hives. If you develop these symptoms after getting a Havrix injection, get medical attention right away and do not get your second, or "booster," shot. Other serious side effects of Havrix may include:

  • irregular heartbeat
  • changes in behavior
  • unusual bruising or bleeding
  • high fever
  • seizures

Havrix may cause less severe side effects, including:

  • mild fever
  • tiredness
  • headaches
  • loss of appetite
  • nausea
  • redness or swelling at the injection site

Other side effects may be possible, so talk to your doctor if any new or unusual symptoms develop after getting a Havrix injection.
