BayRho-D

If your blood type is Rh o(D) negative and your baby`s blood type is Rh o(D) positive, your body may produce a defense (antibodies) against Rh o(D) positive blood . These antibodies usually will not cause a problem if this is your first pregnancy, unless you have had a blood transfusion in the past and have already developed these antibodies. However, if you have other Rh o(D) positive babies in the future, these antibodies may try to destroy the blood of the future babies. If this occurs, it is a very serious condition. Babies born with this condition may need to have their blood replaced.

Rh o(D) immune globulin can be used to treat immune thrombocytopenic purpura, a type of blood disorder . This medicine may be helpful to prevent excessive bleeding.

Rh o(D) immune globulin may also be used if you have recently received a transfusion that contained Rh o(D) positive blood and your blood type is Rh o(D) negative .

Rh o(D) immune globulin is to be administered only by or under the supervision of your doctor or other health care professional .

This product is available in the following dosage forms:
