Side Effects to Report
Some side effects with Havrix
(or other routine childhood vaccines), while occurring infrequently, are potentially serious and should be reported immediately to your healthcare provider. These include, but are not limited to:
- A high fever
- Any unusual behavior changes in a child (aside from the usual fussiness that typically occurs after vaccinations)
- A seizure
- Persistent, inconsolable crying (in a child) lasting for three hours or more
- Signs of an allergic reaction, such as:
- An unexplained rash
- Swelling of the mouth or throat
- Difficulty breathing.
Final Thoughts on Havrix Side Effects
You may experience some or none of the side effects listed in this article. Unfortunately, there is no way for your healthcare provider to know beforehand if you will have problems with this vaccine.
Therefore, make sure to let your healthcare provider know if you develop any adverse reactions after receiving this injection. Also, let your healthcare provider know if something "just does not seem right." While it may not be a Havrix side effect, your healthcare provider will be able to diagnose and treat the problem, or provide reassurance if nothing is the matter.
