Hiberix Warnings and Precautions
If your child has a bleeding disorder, make sure the healthcare provider is aware before giving the child Hiberix. Precautions and warnings also include watching out for febrile seizures (seizures associated with high fevers in young children) in your child, being aware of possible drug interactions, and postponing the vaccine if your child has a moderate or severe illness.
What Should I Tell My Child's Healthcare Provider Before Getting Hiberix?
You should talk to a healthcare provider before your child receives Hiberix® (Hib vaccine) if your child has:
- A moderate or severe illness
- An immune-suppressing condition such as HIV or AIDS, diabetes, or cancer
- A bleeding disorder
- Had any sort of a reaction to any vaccine in the past
- Any allergies, including allergies to foods, dyes, or preservatives.
Make sure to tell the healthcare provider about any medications your child is taking, including prescription and non-prescription medicines, vitamins, and herbal supplements.
Specific Warnings and Precautions
Warnings and precautions to be aware of prior to getting Hiberix include the following:
- If you have an immune-suppressing condition, Hiberix may not be as effective as usual for protection against Haemophilus influenzae type b (Hib).
- Hiberix does not contain thimerosal (a mercury-containing preservative). Parents who are concerned about exposing their children to thimerosal can be confident that this vaccine has no thimerosal (not even trace amounts). Some parents are concerned about the aluminum content of vaccines; Hiberix does not contain aluminum.
- This vaccine is not made from human fetal components or animal components, as some vaccines are.
- Make sure your healthcare provider knows if your child has ever had any serious reactions (including Guillain-Barré syndrome, a neurological disorder) to any vaccines in the past. In some cases, this (and other) vaccines may not be recommended.
- Care must be taken when giving any intramuscular injection (including Hiberix) to individuals with bleeding disorders or who are taking anticoagulant medications, also known as "blood thinners" (see Hiberix Drug Interactions). In some cases, your child's healthcare provider may decide that the risk of the injection is not worth the benefit.
- Febrile seizures (seizures associated with high fevers in young children) have been rarely associated with vaccines, including Hiberix. If your child has a tendency to get febrile seizures, ask your healthcare provider if you should give an anti-fever medication such as acetaminophen (Tylenol®) or ibuprofen (Advil®, Motrin®) to help avoid this problem.
- Your child can receive Hiberix if he or she has a mild illness (such as the common cold). However, it is usually best to postpone the vaccine in the case of a moderate or severe illness.
- Although Hiberix contains tetanus toxoid (a component that improves the effectiveness of the vaccine), it is not a substitute for a tetanus vaccine.
- This vaccine may interfere with urine tests for Haemophilus influenzae type b. If your child's healthcare provider suspects that your child may have a Hib disease, another type of test (other than a urine test) should be used.
- Hiberix is considered a pregnancy Category C medication. This means it is unknown if it is safe for use during pregnancy. However, this is a childhood vaccine and should not be given to pregnant women.
- At this time, it is unknown if Hiberix passes through breast milk. However, this is a childhood vaccine and should not be given to breastfeeding women.
