Havrix Drug Interactions

Medications that suppress the immune system, such as azathioprine, and medications that "thin" the blood, such as heparin, can cause drug interactions with Havrix. This can cause a person's body to not respond properly to the vaccine, or may increase the risk of side effects. To avoid such problems, it is important to tell the healthcare provider about all medicines you are taking before receiving Havrix.
