RhoGAM
Generic name:
Pharmacist-reviewed drug information from the RxWiki encyclopedia.
Overview
RhoGAM is a prescription medication used to prevent Rh immunization, also known as Rh incompatibility. This occurs when a person who has an Rh-negative blood type receives blood or blood products that are Rh-positive or when a mother who is Rh-negative is pregnant with a fetus who is Rh-positive. The immune system of an Rh-negative individual will attack Rh-positive cells.
RhoGAM belongs to a group of drugs called immunoglobulins. These work by making the immune system work better.
This medication is available in an injectable form to be given directly into a muscle (IM) by a healthcare professional.
Common side effects of RhoGAM include pain and redness at the site of injection, rash, body aches, and fevers.

Drug interactions
Tell your doctor about all the medicines you take, including prescription and non-prescription medicines, vitamins, and herbal supplements. Especially tell your doctor if you require immunizations. RhoGAM may impair the efficacy of live vaccines such as measles, mumps, and varicella. Administration of live vaccines should generally be delayed until 12 weeks after the final dose of RhoGAM. If RhoGAM is administered within 14 days after administration of a live vaccine, the efficacy of the vaccination may be impaired. The postpartum vaccination of rubella-susceptible women with rubella or MMR vaccine should not be delayed because of the receipt of RhoGAM.

Pregnancy
Tell your doctor if you are pregnant or plan to become pregnant.
The FDA categorizes medications based on safety for use during pregnancy. Five categories - A, B, C, D, and X – are used to classify the possible risks to an unborn baby when a medication is taken during pregnancy.
RhoGAM falls into category C. No studies have been done in animals, and no well-controlled studies have been done in pregnant women. RhoGAM should be given to a pregnant woman only if clearly needed.
Breastfeeding
Tell your doctor if you are breastfeeding or plan to breastfeed.
It is not known if RhoGAM crosses into human milk. Because many medications can cross into human milk and because of the possibility for serious adverse reactions in nursing infants with use of this medication, a choice should be made whether to stop nursing or stop the use of this medication. Your doctor and you will decide if the benefits outweigh the risk of using RhoGAM.
