Engerix-B

When and How to Take It

Some general considerations to keep in mind with Engerix-B include the following:
 
  • This vaccine is typically given as three or four doses, depending on the age of the individual and the specific dosage used.
     
  • For infants, this vaccine is injected into a muscle (intramuscularly), usually in the thigh. In adults and older children, the upper arm can be used.
     
  • If absolutely necessary, Engerix-B can be injected subcutaneously (just under the skin), instead of intramuscularly. However, this method of injection might reduce the effectiveness of the vaccine and may increase the risk of certain side effects, such as lumps at the injection site.
     
  • People can be vaccinated if they have a minor illness, such as the common cold. However, the Engerix-B vaccine should be postponed if the individual is moderately or severely ill.
     

Engerix-B Dosing Information

The specific dose and schedule for this vaccine will vary, depending on the following factors:
 
  • Your age
  • Your previous vaccination history
  • Your kidney function, especially if you are on dialysis.

Side Effects

Just like any vaccine, Engerix-B may cause side effects. However, not everyone who receives the vaccine will experience problems. In fact, most people tolerate it well, with only minor side effects, if any. If adverse reactions do occur, in most cases, they are minor and either require no treatment or can be treated easily by you or your healthcare provider. Serious reactions are less common.
 
Some of the most common side effects seen with Engerix-B include but are not limited to:
 
  • Fatigue
  • Dizziness
  • Headaches
  • Fever
  • Injection site reactions, such as pain, redness, or swelling.
