When is WinRho
given?
®
WinRho
is given at 28 weeks and when
you deliver, if your baby is Rh positive.
®
Do I need WinRho
every time I get pregnant?
®
WinRho
is recommended with each pregnancy. It will help protect your baby and any
future pregnancies.
Once your body makes antibodies, they do not go away. Every time you get pregnant, the
risk to your baby is more serious.

What are the risks of WinRho
?

WinRho
is a blood product. These steps are taken to make it safe:
all donors are tested for viruses (e.g., HIV, Hepatitis B, Hepatitis C)
the product is filtered and treated to kill viruses
®
WinRho
has been used since 1968 in Canada with very few serious effects reported. If
you have questions, talk to your doctor or healthcare provider.

What if I choose not to get WinRho
?

Without WinRho
, there is a 12 percent chance you will form Rh antibodies that can harm
your baby. The risk increases with each pregnancy.
®
What are the side effects of WinRho
?

have no side effects. Rarely, WinRho
can cause:
pain at the injection site
fever (temperature over 38.5 °C or 101.3 °F)
feeling weak and unwell (malaise)
a headache
an allergic reaction (e.g., hives), which is usually not bad and goes away quickly
