Drugs and Foods to Avoid

Ask your doctor or pharmacist before using any other medicine, including over-the-counter medicines, vitamins, and herbal products.

  • Your child should not take aspirin or medicines that contain aspirin (such as cold medicines) for 6 weeks after receiving this vaccine. Carefully check the label of any pain, headache, or cold medicine you give to your child to be sure it does not contain aspirin or salicylic acid.
  • Immune globulin and blood or plasma transfusions should not be given at the same time as this vaccine.
  • Make sure your child's doctor knows if your child is using a medicine that weakens the immune system, such as a steroid or cancer medicine. This vaccine may not work as well if your child has a weak immune system.
  • Talk to your doctor before your child gets flu shots or other vaccines after he or she receives this vaccine.

Warnings While Using This Medicine

  • Using this vaccine while pregnant can harm the unborn baby. Women of childbearing age should avoid getting pregnant for 3 months after receiving this vaccine.
  • Make sure your child's doctor knows if your child has a history of a brain injury, seizures, bleeding disorders (such as thrombocytopenia), or high fevers.
  • Tell your child's doctor if your child has had an allergic reaction to eggs.
  • Children who have received this vaccine have developed a fever and in some cases a fever with seizures. Talk with your child's doctor if you have concerns about this.
  • Your child should avoid close contact with people at high risk for catching the varicella virus for 6 weeks after receiving this vaccine. People who are at risk for catching the virus are pregnant women, newborn babies, and anyone who has a weak immune system that keeps them from fighting infections.
  • Make sure your doctor knows if your child has recently had a blood or plasma transfusion, or received an immune globulin injection. Tell your doctor if your child needs to receive a tuberculin skin test.
  • This vaccine contains albumin, which comes from human blood. Some human blood products have transmitted certain viruses to people who have received them. The risk of getting a virus from medicines made of human blood has been greatly reduced in recent years. This is the result of required testing of human donors for certain viruses, and testing during manufacture of these medicines. Although the risk is low, talk with your child's doctor if you have concerns.
