PedvaxHIB Drug Interactions
Azathioprine, Coumadin, cortisone, and methotrexate are among the products that can cause drug interactions with PedvaxHIB. When these medications are combined with PedvaxHIB, they can cause the vaccine to lose its effectiveness. Therefore, it is important to tell the healthcare provider administering the injection about all medicines your child is currently taking, including vitamins and supplements.
