How does this medication work? What will it do for me?
Rotavirus vaccine is used to prevent infection by the rotavirus, which causes severe gastrointestinal (digestive system) infections in newborns and young children. The vaccine is made up of live virus that has been weakened so that it does not cause infection. The vaccine works by exposing your body to the weakened virus, thus allowing your body to produce its own protection (antibodies) against the disease.
Rotavirus is the most common cause of severe diarrhea in newborns and young children. It is spread from hand-to-mouth contact with stools from an infected person. Although most children get over this infection on their own, some develop severe vomiting, diarrhea and dehydration, needing hospital care to recover.

Are there any other precautions or warnings for this medication?
Before you begin using a medication, be sure to inform your doctor of any medical conditions or allergies you may have, any medications you are taking, whether you are pregnant or breast-feeding, and any other significant facts about your health. These factors may affect how you should use this medication.
Fever: Your child's doctor may decide to delay this vaccine if your child has an acute infection or fever. Mild infections without fever, such as colds, usually do not require delay of the vaccine.
Immune problems: As with any vaccine, rotavirus vaccine may not provide complete protection against rotavirus for all people. When used for children with impaired immune systems, rotavirus vaccine may not create enough of an antibody response to protect against infections caused by these bacteria. Also, this vaccine may not be effective for people receiving immunosuppressive therapy (e.g., some medications used to treat cancer or for transplant recipients).
Other vaccines: Rotavirus vaccine may be given in the doctor's office at the same time as your child receives other routine infant vaccinations.
Pregnancy: This vaccine is intended for infants and young children only and should not be used by pregnant women.
Breast-feeding: This vaccine is intended for infants and young children only and should not be used by breast-feeding women.
What other drugs could interact with this medication?
There may be an interaction between rotavirus vaccine and any of the following:
- immune globulin
- corticosteroids (e.g., budesonide, dexamethasone, hydrocortisone, fluticasone, prednisone)
- medications to treat cancer (e.g., carboplatin, cyclophosphamide, doxorubicin, ifosfamide, vincristine)
- tuberculin skin tests
Tell your doctor or prescriber about all prescription, over-the-counter (non-prescription), and herbal medications that you are taking. Also tell them about any supplements you take. Since caffeine, alcohol, the nicotine from cigarettes, or street drugs can affect the action of many medications, you should let your prescriber know if you use them. Depending on your specific circumstances, your doctor may want you to:
- stop taking one of the medications,
- change one of the medications to another,
- change how you are taking one or both of the medications, or
- leave everything as is.
An interaction between two medications does not always mean that you must stop taking one of them. Speak to your doctor about how any drug interactions are being managed or should be managed.
